For those would-be investors wanting to jump into the stock market but wondering which stock to buy, legendary investor Warren Buffett has a suggestion: Try buying 500 stocks instead.“In my view, for most people, the best thing to do is own the S&P 500 index fund,” Buffett said at Berkshire Hathaway’s annual meeting in May. But what is the S&P 500, and how do you invest in one of its funds?Here’s an intro to how S&P 500 funds work, and whether one might be a good fit for your portfolio.What is the S&P 500?The S&P 500, or S&P, is a stock market index comprising shares of 500 large, industry-leading U.S. companies. It is widely followed and often considered a proxy for the overall health of the U.S. stock market.Standard & Poor’s, an American investment information service, created the index in 1957. Every quarter, its investment committee meets to review which stocks belong in the index based on each company’s market size, liquidity and group representation. Today, 505 stocks constitute the index, since some of the 500 companies have more than one class of shares.Contrary to popular belief, the stocks forming the index are not the 500 biggest U.S. companies, but they are arguably the 500 most important companies. Over .2 trillion is invested through the index, with these 505 stocks representing about 80% of the total U.S. stock market’s value.The S&P 500 is a cap-weighted index, meaning each stock within the index is weighted according to its market capitalization, or total market value (number of outstanding shares multiplied by current market price). The larger the company, the greater its influence on the index.As of Aug. 31, 2020, these are the top 10 companies by index weight in the S&P 500:Apple.Microsoft.Amazon.Facebook.Alphabet, Google’s parent company (shares in classes A and C).Berkshire Hathaway.Johnson & Johnson.Visa.Procter & Gamble.How do you invest in the S&P 500?An index is a measure of its underlying stocks’ performance, so you cannot directly invest in the index itself. Buying every company’s shares would be an arduous task (think 505 separate transactions), but thankfully there are index funds and exchange-traded funds, or ETFs, that replicate the index, effectively doing that work for you.While all S&P 500 funds track the holdings of this index, an investor must consider whether using an index fund (a passively managed mutual fund) or an ETF makes the most sense for them. The good news when weighing index funds versus ETFs is that there are solid S&P 500 options in each category, and all of these products leverage the diversity of the index itself.Because the S&P 500 is weighted by each company’s market capitalization, the larger companies in the index can sometimes have an outsize impact on the performance of the larger index. In other words, a big dip in price for Apple shares can create a dip in the index as a whole. Because of this, some investors prefer to purchase the S&P 500 in an equal-weighted format, so that each company has the same impact on the index. This is meant to create an index that is more representative of the overall U.S. market.After deciding your preference for an index fund or ETF, cap-weighted or equal-weighted, you can begin narrowing down which S&P 500 fund to purchase. To minimize your costs, look into each fund’s expense ratio — the percentage of your assets you’ll pay in fees each year — to see how they compare.Fees are important here since all of these funds track the same index, which means their returns should be roughly the same. The lower the fee, the more of that return you keep.Should you invest in the S&P 500?There are a number of things to think about before you choose any investment. But an S&P fund can generally be a good choice if you want to add broad exposure to the U.S. stock market to your portfolio.“The S&P 500 is a key part of a diversified investing strategy because it’s a good bet that the U.S. economy will continue to succeed and grow in the long term,” says Tony Molina, senior product manager at Wealthfront. The U.S. has the largest economy and stock market in the world, and is one of the most resilient and active, especially when it comes to innovation. That’s why it’s a no-brainer to include the S&P 500 as part of your portfolio.”Larger companies are generally more stable to invest in because they are well-established and widely followed. Thus, these stocks usually have less risk and lower volatility. The S&P 500 combines large companies across various industries, so investors access a broad, diversified mix of companies when investing in it.Choosing an index fund or ETF can also help investors avoid — or at least minimize — the behavioral pitfalls from stock-picking, which is a losing strategy, says Dejan Ilijevski, president of Sabela Capital Markets.Ilijevski cites the May 2018 study by professor Hendrik Bessembinder at Arizona State University, which examined investments in publicly traded U.S. stocks between 1926 and 2016 and found that just over 4% of the companies accounted for the total wealth created.“Picking those few individual winners is impossible,” Ilijevski says. “Your best bet is to own as much of the market with a fund that tracks the index.”Using index funds and ETFs can help investors generate strong returns while also minimizing their costs, says Kevin Koehler, chartered financial analyst and director of the investment strategy group at Miracle Mile Advisors in Los Angeles.“Investing in the S&P 500 the past 25 years would have given an investor over a 10% annualized return, proving that an investor does not need to be paying high expenses to get good market returns,” Koehler says.Are there drawbacks to investing in the S&P 500?There are caveats to consider. The S&P 500 consists of only large-cap U.S. stocks. Portfolio diversification encompasses buying mid- and small-cap companies along with large-caps; allocating funds to international companies along with domestic ones; and including bonds, cash and potentially other asset classes with stocks.Koehler also notes drawbacks in the S&P 500 related to its market-cap weighting.“As passive investing increases, investors are continually investing in S&P 500 funds, which has contributed to a ‘rich get richer’ problem, where the largest stocks are getting larger due to S&P 500 investing, rather than individual stock investing,” Koehler says. “This can lead to higher volatility, as active managers sell an individual stock on top of index funds selling a portion. The market could continuously be overvalued compared to its underlying value.”But relative to the downsides of many investment types, the flaws of S&P 500 funds seem relatively minor, especially when used as a part of your overall portfolio and held for the longer term. This helps explain why icons like Buffett have so publicly endorsed them.“I happen to believe that Berkshire is about as solid as any single investment can be, in terms of earning reasonable returns over time,” said Buffett at the May meeting, speaking about the investing company he’s turned into an empire. “But, I would not want to bet my life on whether we beat the S&P 500 over the next 10 years.”More From NerdWallet4 Ways Women Can Invest in Other WomenHow the Pros Ride Market Volatility — and Why You Shouldn’tIf Doing Less Means Saving More, Try These 5 Money MovesTiffany Lam-Balfour is a writer at NerdWallet.

Feeling lucky? Employees of United Airlines weren't.On Monday, United quickly shelved plans to replace quarterly employee bonuses with a 0,000 lottery prize, after a stinging backlash from its workforce.The lottery, which the airline announced on Friday, would have paid 0,000 to one lucky employee selected at random, and smaller bonuses of ,000 or ,000 to about 1,300 more. Other employees would have gotten prizes including 50 vacation packages or 10 Mercedes.The overwhelming majority of United's 90,000 workers would have lost bonuses that paid up to ,500 over the course of the year."Our intention was to introduce a better, more exciting program, but we misjudged how these changes would be received by many of you," said Scott Kirby, president of United Continental, the holding company for the airline, in an email to employees. "We are pressing the pause button," he wrote.Experts on compensation and workplace culture said they had never heard of a company of United's size and stature trying this kind of lottery program."I really thought it was a joke when I first heard of it," said Tom Gimbel, founder and CEO of LaSalle Network, a national staffing and recruiting firm. "It's very amateurish."The backlash and reversal comes while United is negotiating a new union contract with its pilots. The union wasn't happy with the lottery."This just puts a bad taste in our mouths," said Roger Phillips, a United pilot and spokesman for the pilots union at the airline. 1497

  

Forecasters have warned of potentially record-breaking temperatures in Spain and Portugal this week as much of Europe swelters in a heat wave that has left some farmers suffering drought conditions.The UK Met Office said parts of the Iberian peninsula could beat the all-time continental European record of 48 degrees Celsius (118.4 degrees Fahrenheit) this week, with inland areas likely to be hotter than the coast.That record was set in the Greek capital, Athens, in July 1977. According to the World Meteorological Organization, the record for Spain is currently 47.3 Celsius, while for Portugal it's 47.4 Celsius.The Portuguese capital, Lisbon, could see a high of 41 Celsius on Saturday, according to CNN forecasters. Its average temperature is 28 Celsius for this time of year.A heat wave warning was in place across much of southern and eastern France on Thursday. The national meteorological agency, Méteo France, said Wednesday that temperatures in the south of the country would come close to record highs in the coming days.Vacationers have been warned to take precautions against extreme temperatures, as the heat wave coincides with the peak holiday season in Europe.Vulnerable people such as children and the elderly could be at risk of heat stroke, which occurs when a person's core body temperature rises above 40 Celsius and can lead to permanent brain, heart and kidney damage and, in more severe instances, death.Spain's meteorological office, Aemet, warned of high temperatures lasting from Wednesday into early next week.The hot spell will be particularly intense and long-lasting in Spain's southwest, the central zone and the Ebro Valley, with temperatures above 40 Celsius, it said. In inland areas of the northwestern region of Galicia, normally known for its mild, rainy weather, the mercury could hit 41 Celsius on Thursday, it said.Wildfires have raged in Sweden and neighboring Scandinavian nations in recent weeks amid unusually hot, dry conditions. Some places in Sweden have had their driest May-to-July period on record, according to its meteorological agency, and a number of weather stations have recorded only 10% to 15% of their normal rainfall.The United Kingdom is also experiencing a prolonged spell of hot, dry weather. The Met Office said last week that some parts of east and southeast England had had virtually no rain for more than 50 days. Thunderstorms over the weekend brought with them rain and cooler weather, but temperatures are again on the rise.The National Farmers' Union hosted an emergency summit Wednesday with representatives of the UK government, at which it called for its members to be given help to cope with the conditions. Farmers are struggling with irrigation, heat stress on livestock, the loss of crops and a shortage of forage for animals, the union said."The impacts of the dry and hot weather have been hugely challenging for many farms across the country, with many not seeing such weather in their lifetimes," said NFU President Minette Batters.The UK Environment Agency said it would allow greater flexibility in the rules on water extraction to help farmers manage the situation.Meanwhile, German Agriculture Minister Julia Kl?ckner wrote to the European Commission on Wednesday urging it to take steps to help farmers affected by drought. Food for livestock could become scarce in the coming weeks, she warned.The past four months in Germany have been very hot and dry, particularly in the north and east of the country.The European Commission announced measures Thursday to help farmers cope, including giving them higher advance payments from EU funds and granting more flexibility to use land that would normally be left fallow to grow animal fodder.The latter measure will be of particular help to livestock farmers, it said. 3815
