Why I just bought these 2 unloved FTSE 100 shares

first_img See all posts by David Barnes “This Stock Could Be Like Buying Amazon in 1997” Why I just bought these 2 unloved FTSE 100 shares Our 6 ‘Best Buys Now’ Shares David Barnes owns shares in Taylor Wimpey, Lloyds Bank, Experian, Smith & Nephew, Unilever, Hargreaves Lansdown and Sage. The Motley Fool UK has recommended Experian, Hargreaves Lansdown, Lloyds Banking Group, Sage Group, and Unilever. Views expressed on the companies mentioned in this article are those of the writer and therefore may differ from the official recommendations we make in our subscription services such as Share Advisor, Hidden Winners and Pro. Here at The Motley Fool we believe that considering a diverse range of insights makes us better investors. I’m sure you’ll agree that’s quite the statement from Motley Fool Co-Founder Tom Gardner.But since our US analyst team first recommended shares in this unique tech stock back in 2016, the value has soared.What’s more, we firmly believe there’s still plenty of upside in its future. In fact, even throughout the current coronavirus crisis, its performance has been beating Wall St expectations.And right now, we’re giving you a chance to discover exactly what has got our analysts all fired up about this niche industry phenomenon, in our FREE special report, A Top US Share From The Motley Fool. Simply click below to discover how you can take advantage of this. Enter Your Email Addresscenter_img Last week I bought two unloved FTSE 100 shares on the back of some disappointing financial results.As a rule, I try to build my portfolio around non-cyclical quality growth stocks, or progressive income stocks where I think the company in question has a good long-term runway of growth ahead of it.5G is here – and shares of this ‘sleeping giant’ could be a great way for you to potentially profit!According to one leading industry firm, the 5G boom could create a global industry worth US$12.3 TRILLION out of thin air…And if you click here we’ll show you something that could be key to unlocking 5G’s full potential…Examples might be Smith & Nephew, Experian, Unilever, Hargreaves Lansdown, Sage or Halma. In fact, I think that’s a pretty decent growth starter portfolio. But occasionally, I get tempted into a cyclical struggling company where I think there’s tremendous value over the medium term.This FTSE 100 bank is at an eight-year lowShares in Lloyds bank (LSE: LLOY) fell to just 26p last Thursday. The 12-month high was 70p so the share price has tumbled 63%. Over the same period, the FTSE 100 is down by about 23%. I would expect this underperformance. They say that banks are first in and first out of an economic downturn. It’s a highly cyclical company.The bank has announced a loss before tax of £602m for the first half. It also set aside a further £2.4bn for bad debts in the second quarter. Low Interest rates are squeezing margins and a struggling economy paints a bleak economic picture. The dividend is suspended and may not return in full for some time.But I think this is exactly the time when you should consider buying a cyclical share. Be greedy when others are fearful and all that.I agree with Harvey Jones that the key here is time and patience. This is a share to buy and ignore for five years. If/when the economy recovers and the dividend gets anywhere close to 3p per share again, that could be a yield of 11.5% you’re locking in.If banks weren’t cyclical enough for you…The other FTSE 100 company I’ve taken the plunge with is housebuilder Taylor Wimpey (LSE: TW). As you might expect, if you’re a housebuilder that can’t build houses, revenues are going to suffer.The firm posted a pre-tax loss of £39.8m for the first half of the year. Full-year completions are expected to be around 40% down. The generous dividend (including special dividend payments) has long since been scrapped.But I see these problems as temporary. Net cash actually surged to nearly £500m and the total order book was up 23% from a year ago. The government stamp duty holiday should also help boost sales.As I’ve said before, there’s a chronic shortage of housing in the UK. The government has promised to build 300,000 per year. This situation hasn’t changed. A price-to-earnings ratio of eight is also appealing for this FTSE 100 builder.As the economy begins to recover, surely the dividends will return. They were running at over 10% last year. There’s hopefully some upside in the share price as well. This is another share to buy and forget about for a few years and I think your patience will be rewarded. Renowned stock-picker Mark Rogers and his analyst team at The Motley Fool UK have named 6 shares that they believe UK investors should consider buying NOW.So if you’re looking for more stock ideas to try and best position your portfolio today, then it might be a good day for you.

Rugby League legend Ellery Hanley MBE, one of Yorkshire’s finest sportsmen, with an incredible 30 year sporting career, is fronting The Sick Children’s Trust: 2010 Tower Power Challenge.Ellery is encouraging runners of all abilities to get to the top of Bridgewater Place, the hard way…by running up the stairs. 30 Storeys, 600 steps for one great cause.The Sick Children’s Trust is organising a tower run up the tallest building in Yorkshire, Bridgewater Place in Leeds on the 22nd of May 2010.This will be the first of its kind outside London and aims to raise £90,000 towards its target of £1.7 million for ‘The Big Move’ appeal. The SCT Leeds ‘Home from Home’, Eckersley House, has to be relocated from St James’s Hospital to Leeds General Infirmary. If The Sick Children’s Trust doesn’t move Eckersley House hundreds of children will go through prolonged treatment without their families being close by.“Tower running is one of the toughest new sports to capture the imagination of fitness addicts all over the world. I’m encouraging runners to be one of the 300 hundred people running up 600 stairs in this adrenaline fuelled tower race. The 2010 Tower Power Challenge goes one further than your average 10k race. The average runner will burn 704 calories an hour flat running—but racing upstairs increases that by 50 percent—it’s quite a challenge,” says Ellery.“But it’s not just an endurance test, the 2010 Tower Power Challenge is a brilliant fundraiser and Eckersley House needs public support now more than ever to complete the build of the new house at the Leeds General Infirmary. We need to raise the final £500,000 to open new house in June.” says Ellery.The Sick Children’s Trust ensures that the very basic of all medicines has a chance to work; family love and support. The charity helps families stay close by to their sick child at all times making a real difference to their recovery.Vicki Smith, fundraiser for the 2010 Tower Power Challenge says, “This is our final fundraising drive for the new house and we’re looking for enthusiastic runners to help us raise £90,000 towards our £1.7million target for The Big Move appeal. Now’s the time to lace up the sneakers and download that form and start training. The Tower Power Challenge is an unusually healthy way to get to the top!”Participants must be 18 years old or over and a training plan will be available to download on The Sick Children’s Trust website.Register and download your sponsorship forms at www.sickchildrenstrust.orgOr contact us via email: [email protected] or phone Vicki, Regional Fundraiser, on 07525 424406 About Howard Lake Howard Lake is a digital fundraising entrepreneur.

National Day of Mourning honors Indigenous resistance

first_imgWW photo: Liz GreenIndigenous people and their supporters gathered on Coles Hill in Plymouth, Mass., for the 45th annual National Day of Mourning, organized by United American Indians of New England. A spirited march followed a rally, and then a potluck dinner and social at two local churches. NDOM brings the truth to light about the real meaning of “Thanksgiving” for Native peoples — genocide, theft of Indigenous lands and racist repression.The Nov. 27 all-Native rally program included Juan Gonzalez, who performed opening prayers and later spoke; Maya, who spoke about the history of Guatemala; Moonanum James, from the Aquinnah Wampanoag Nation, who reviewed the origins of NDOM; Mahtowin Munro, from the Lakota Nation, who spoke about the solidarity of Indigenous peoples with other movements fighting oppression, including Ferguson; Bert Waters, also from the Wampanoag Nation, who read a solidarity statement from political prisoner Leonard Peltier; Inarunika, from the Taino Nation, who talked about the first invasion of the Americas by Christopher Columbus; and Stephanie Hedgecoke, of the Cherokee Language and Cultural Circle, who spoke about the struggle against fracking and the Keystone XL Pipeline.FacebookTwitterWhatsAppEmailPrintMoreShare thisFacebookTwitterWhatsAppEmailPrintMoreShare thislast_img read more

Studies Showing Voter Opposition to EPA Regs

first_img Facebook Twitter SHARE By Andy Eubank – Nov 3, 2014 Previous article2014 FFA National Agricultural Proficiency Winners AnnouncedNext articleMorning Outlook Andy Eubank SHARE As the public comment period for the U.S. Environmental Protection Agency’s proposed greenhouse-gas rules on existing power plants hits the home stretch to closing date and with the election here, studies are piling up about the impact these regulations will have on the nation and the reaction voters have to them.Among those studies is an independent evaluation by Energy Ventures Analysis, which uncovered significant flaws in the EPA’s estimates of the compliance cost of its Clean Power Plan, which will regulate carbon-dioxide emissions from more than 3,000 U.S. coal-fired power plants. According to the study, the regulations as a part of the Clean Power Plan will drive wholesale electricity costs up by $274 billion, non-power natural gas prices up $80 billion, and costs to replace coal-fired power by $53 billion.Another study by NERA Economic Consulting also reveals significant negative economic impacts resulting from the EPA’s Clean Power Plan. The NERA analysis indicates that power-plant costs to comply with the EPA’s plan “could total $366 billion in today’s dollars,” and raise electric bills by double digits in 43 states, with 14 states “facing peak-year electricity prices that exceed 20 percent.”The NERA study found that the regulations’ impact on global climate will be pretty meaningless, citing that atmospheric CO2 levels would be reduced by only less one-half percent – which comes to about two one-hundredths of a degree in temperature, and sea-level reductions by only the thickness of three sheets of paper. Yet consumer and business energy costs could rise to $41 billion or more per year, the NERA analysis reports.Voters vote “No” to EPA regulationsVoters have expressed concerns over the past few months with the administration’s approach on the issue, and many find the EPA’s plan out of step with what citizens want.The Partnership for a Better Energy Future very recently revealed results from a multistate poll of likely voters. The results showed a major gap between the EPA’s actions, and the voting public’s opinion on the issue. Nearly half of those polled say they are not willing to pay a single dollar more in their energy bill to accommodate the new EPA regulations. Additionally, the majority believe the United States cannot afford new costs and potential job losses resulting from the EPA regulations. Middle-class voters and seniors are among the top opponents of the rule. The poll also finds that public opposition is led by concerns about job loss, possible energy rationing and increased electricity rates, especially for the middle class​.​“EPA’s push to implement one of the most complicated and costliest rules in history is creating real concerns across the country that should not be ignored,” said U.S. Chamber of Commerce Institute for 21st Century Energy President and CEO Karen Harbert. “This poll affirms what we’re hearing from state​s​ businesses and families that will be forced to comply. The EPA should heed these concerns and abandon its current approach, which will bring negative consequences for our entire economy with very little environmental benefit in return.”Indiana Voters in Sync with National PollsThese national polls fall in line with two other polls taken in Indiana in recent months. One such poll by 60 Plus Association revealed that Hoosier senior citizens – most identifying themselves as Democrat or Independent voters – are concerned about increasing energy costs due to new regulations under consideration the EPA. The poll surveyed 609 registered voters, age 55 and over, from across the state. A majority of survey respondents indicated the president and Congress should be focusing on keeping energy prices low, rather than creating new regulations for power plants. 79 percent of the respondents said they “definitely” plan to vote in the upcoming November election.Another poll taken by the Indiana Coal Council revealed similar findings from participants from northern and central Indiana. When choosing a source for electricity, 81 percent of respondents reported that reliability was the most important factor for them, closely followed by 73 percent of respondents who stated low price and affordability are significant considerations when choosing an energy source.But from business and industry experts to independent electric-grid operators, to former EPA chiefs and the U.S. Department of Energy, all agree the EPA’s Clean Power Plan will not achieve what voters want, and it won’t achieve environmental benefits of any worthwhile level.“Seems like a bad plan overall,” said Don Kuriowa, a Hoosier voter who has been watching closely where the candidates stand on this issue. “I will have to seriously consider whether to give my vote to any federal or state candidate that isn’t aware and actively voicing opposition to the EPA’s excessive regulations.” Source: Indiana division of Count on Coal, sponsored by the National Mining Association Home Energy Studies Showing Voter Opposition to EPA Regs Studies Showing Voter Opposition to EPA Regs Facebook Twitterlast_img read more

Students help elders “Cycle Without Age”

She currently serves as a line editor. Makenzie Stallo Ann Louden’s Legacy printEvery Thursday, the residents of the Trinity Terrace retirement community gather at Trinity Trail for a bike ride. But they don’t do it alone. The residents relax and enjoy the ride in specialized rickshaws piloted by TCU students.Trinity resident Emma Coley has never missed a ride in the rickshaw.“They bought the two rickshaws and set it up and asked me if I would be interested, and I said sure,” Coley said. “Anything to get me out, and I love it and I wouldn’t miss one.”The volunteer “pilots” of these rickshaws are all TCU students, most of whom have been recruited by sociology instructor Dr. Keith Whitworth.“It’s just a way for the students to give back to the community and for the residents to experience something that they wouldn’t be able to otherwise,” Whitworth said. This project is part of an international movement called Cycling Without Age. It was founded by Ole Kassow in Copenhagen, Denmark in 2012, and is now in 28 countries around the world. Kassow’s mission was to get elderly citizens with limited mobility back on bicycles.The official website states: “Life unfolds at all ages, young and old, and can be thrilling, fun, sad, beautiful and meaningful. Cycling Without Age is about letting people age in a positive context – fully aware of the opportunities that lie ahead when interacting in their local community.”Spending time outdoors has great health advantages for senior citizens, but too few actually reap these benefits, as reported by Community Home Health Care.Trinity resident Carol McCarty said a lot of residents never venture outside. “Some people never leave or get out of their room, except for when they eat and then they go back to their room,” said Trinity resident Carol McCarty. “They never go outside.”For senior citizens, going outside can improve the immune system, boost vitamin D levels, improve focus and recover from injuries at a faster rate, according to Community Home Health Care. Quick List Venngage InfographicsThe program came to the attention of Keith Manning, the operations project manager for Trinity Terrace, after one of the residents who was an avid cyclist suggested this program to him.Manning said the partnership with TCU was a natural fit.“I love the fact that we have older adults talking with the students, getting to swap life stories and learn about things from each other,” Manning said. “Intergenerationality is one of the founding factors of Cycling without Age.”First-year pre-nursing major Bryce Cherry said he enjoys getting to know the residents on a personal level.“I mainly enjoy the human aspect of it like getting to talk to people and getting to know their stories and everything they’ve been through from homemakers to retired air force colonels,” Cherry said.

June 9, 2021 Find out more Organisation News “The Islamic Republic of Iran has been one of the world’s worst countries as regards cracking down on freedom of the press in connection with the pandemic,” said Reza Moini, the head of RSF’s Iran-Afghanistan desk. “In the light of the recently revealed figures and the government’s continuing denial of the gravity of the health crisis, we can only be extremely concerned about the situation of detainees in general and journalists in particular. We therefore call on Javaid Rehman, the UN special rapporteur on human rights in Iran, to do everything possible to visit Iran’s prisons and report on the situation.” The BBC’s Persian service revealed on 3 August that leaked Iranian government data showed that the real death toll from Covid-19 in Iran was nearly 42,000 – three times the figure of 14,400 that the Iranian health ministry gave on 20 July. Several prisoners of conscience have begun a hunger strike in various prisons. They include Nasrin Sotoudeh, a lawyer who has defended many journalists and who was awarded the Sakharov Prize for Freedom of Thought in 2012. Sotoudeh has refused to eat since 10 August in protest against her current situation and those of other political prisoners. Her husband reports that her physical condition had deteriorated dramatically and that she has been transferred to the prison’s clinic. Follow the news on Iran Ever since March, RSF has been condemning the cover-up about the spread of Covid-19 and the crackdown on independent reporting in Iran, but media outlets and journalists continue to pay the price of the government’s lies.

The newspaper’s editor said it was sanctioned for publishing an interview with a public health specialist under the headline, “The government’s coronavirus case figures cannot be trusted.” Iran is ranked 173rd out of 180 countries in RSF’s 2020 World Press Freedom Index. Reporters Without Borders (RSF) calls on the UN special rapporteur on human rights in Iran to inspect the country’s prisons as soon as possible, now that the revelation of a cover-up of coronavirus deaths in Iran has increased concern about the degree to which prisoners of conscience, including journalists, are exposed to the virus in its over-crowded jails. “For an infectious disease such as Covid-19, we need not only resources but also an appropriate health policy,” he said. “The only thing the prison authorities do is isolate the sick or transfer them to other wings of the prison.” Detainees with Covid-19 should be released so that they can receive the necessary treatment “or at least die with dignity in their family,” he added. Speaking on condition of anonymity, a doctor who works in a prison in Tehran province confirmed to RSF that the prison system was incapable of dealing with the situation resulting from the pandemic.

Public sector staff most stressed

first_img Previous Article Next Article Public sector staff most stressedOn 11 Mar 2003 in Personnel Today Related posts:No related photos. Public sector workers suffer more stress than their private sectorcounterparts, according to a survey by the Chartered Institute of Personnel andDevelopment. Almost 40 per cent of NHS staff and 30 per cent of local government workersfind their work stressful. Yet, according to the poll of 1,000 public andprivate sector staff, only 25 per cent of all staff claim they are stressed. The report Pressure at Work and the Psychological Contract cites the longhours and heavy workloads in the public sector as the biggest reason forstress, followed by a decline in work satisfaction. The report claims the psychological contract – the mutual expectations ofemployers and staff – is under most pressure in the public sector. Only 7 per cent of central government employees believe strongly that theorganisation cares about their opinions, while only 20 per cent feel fairlytreated by their manager. Mike Emmott, employee relations adviser at the CIPD, believes the publicsector must focus on HR if it is to reduce stress levels and improve staffsatisfaction and services. “The NHS has relatively few HR professionals, while national and localgovernment needs to pay more attention to the way people management policiesare implemented,” he said.

Effects of experimental temperature elevation on high-arctic soil microarthropod populations

first_imgAn experiment was conducted to measure the effects of summer warming on the total population densities of soil-dwelling microarthropods in the high Arctic and to compare these results with those from natural between-year and between-site variations. Small polythene tents were used to elevate summer temperatures over 3 years on polar semi-desert and tundra heath in West Spitsbergen, Svalbard, Norway. Soil cores were taken at regular intervals from tented and untented (control) plots and heat extracted for mites (Acarina: Oribatida) and springtails (Collembola). Species present were similar at both sites, but at the start of the experiment total springtail populations were greater at the polar semi-desert whilst oribatid mite densities were equal at both sites. No significant effect of temperature elevation on oribatid mite populations emerged, even after 3 years. By contrast, springtail numbers were significantly lower on tented versus control plots at the polar semi-desert at the end of year 3, but not so at the tundra heath. Collembola numbers declined at both sites during the warm dry midsummers of 1992/1993 and this was most marked at the better drained polar semi-desert site. Over the equivalent period total oribatid mite populations, while relatively more stable, increased significantly at the polar semi-desert as a result of an increase in the number of juveniles. Results are interpreted in the context of the ecophysiological adaptations of oribatid mites and springtails to soil temperature and moisture. The resulting survival characteristics are considered in relation to the temperature and moisture characteristics of the two sites. The experiment demonstrated that year to year variation in climate, interacting with physical differences between sites, produced an equal or greater effect on microarthropod numbers at any one site than the 8–10% increase in “heat availability” (day degrees above zero) resulting from the summer tent treatment. The limitations of the use of tents to elevate soil temperatures are discussed. Comparisons are made with microarthropod population data from other polar and alpine sites.last_img read more
