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.

Fred Meyer stores will phase out all sales of guns and ammunition, according to parent company, Kroger."Fred Meyer has made a business decision to exit the firearms category," Kroger spokesperson Kristal Howard said in an emailed statement on Monday.The company said it made the decision last week "after evaluating changing customer preferences" and also "softening consumer demand" for guns for the last several years.Annual gun sales at Fred Meyer are million and "continue to decline," according to the company."More recently Fred Meyer has been transitioning away from gun departments as a result of the ongoing work to optimize space in Fred Meyer stores," the company said.The news comes after Kroger announced last week that the grocer will stop selling magazines featuring "assault rifles."Earlier this month, Kroger said its Fred Meyer stores would stop selling guns to anyone under 21, even though the law permits the sale of rifles to anyone 18 or older. Kroger has 45 Fred Meyer stores located in four Western states.This followed a decision by Dick's Sporting Goods Chief Executive Officer Edward Stack to stopping selling what he called "assault-style rifles" and high capacity magazines after a mass shooting at a high school in Parkland, Florida.Walmart, which stopped selling military-style semiautomatic rifles back in 2015, also recently raised its gun purchase age from 18 to 21.The-CNN-Wire 1423

For years, Toys "R" Us was an American success story.Now the discount toy retailer is in its final chapter. The company filed for bankruptcy in September. On Wednesday, Toys "R" Us told employees that it would close or sell all its stores in the United States.It's an ignominious end for the company that was once the toy industry's powerhouse. In the second half of the 20th century, just after the Baby Boom, Toys "R" Us grew into a dominant retail chain thanks to its low prices and a knack for keeping the nation's hottest toys in stock."Toys 'R' Us, Big Kid on the Block, Won't Stop Growing," a Wall Street Journal headline blared in 1988.It all started in 1948, when Charles Lazarus, age 25, opened a baby furniture store called Children's Bargain Town in Washington, D.C. He knew Americans returning from World War II were starting families and needed somewhere to stock up on nursery decor.But before long, Lazarus discovered that the real money was not in cribs, but in toys.Toys break, or go out of fashion — which means parents need to go to the store more often, Toys "R" Us explains in its online company history.In 1957, Lazarus opened his first store stocked only with toys. It was modeled after a supermarket, with items stocked high on shelves and a wide assortment of choices. He named it Toys "R" Us — with a backwards "R" in the logo that was supposed to look it it was drawn by a kid.The mainstays of the iconic Toys "R" Us marketing campaigns emerged over the next two decade. Dr. G. Raffe, which had been used to advertise Children's Bargain Town, became "Geoffrey."In a Washington Post ad from 1970, an eager Geoffrey touted "super giraffic selections" inside "super giraffic stores!" Geoffrey made his first TV appearance in 1973. The "I don't want to grow up" jingle made its debut in the early 1980s.In the meantime, Toys "R" Us was booming.The company went public in 1978 after the bankruptcy of onetime parent Interstate Stores. It quickly became a Wall Street favorite. In 1980, the Los Angeles Times called Toys 'R' Us "one of the New York Stock Exchange's hottest stocks.""What we are is a supermarket for toys," Lazarus told the Washington Post in 1981. "We don't have a competitor in variety. There is none."The Washington Post story favorably compared Toys "R" Us to another American giant: McDonald's."Like McDonald's, with its regimented service and standardized burgers and fries, Toys 'R' Us has become an American institution," the article said.Toys 'R' Us was also known in the corporate world for its sophisticated use of computers."One thing that sets the Toys 'R' Us operation apart is that Mr. Lazarus knows precisely what his customers are buying," a 1985 Wall Street Journal article said. "Each product is tracked by computer, and that helps the chain spot hot-selling items weeks before most competitors do."Lazarus also kept his stores stocked with a variety of baby products, like diapers and formula, so shoppers would have a reason to shop year-round.Things started to go awry in the 1990s. In 1994, Lazarus stepped down as CEO. But the biggest change came when Walmart started offering lower prices on diapers, according to toy industry analyst Jim Silver.While Toys "R" Us remained a destination during the holidays, it lost regular shoppers during the rest of the year."That changed everything," Silver said.In 2001, Toys "R" Us opened a flagship store in Times Square, complete with a 60-foot Ferris wheel and a life-size Barbie dollhouse, in order to juice enthusiasm. But the costs were "astronomical," Silver said.On shaky ground, Toys "R" Us was taken private by a group of private equity firms in 2005. Bain Capital, Kohlberg Kravis Roberts & Co. and Vornado Realty Trust bought the company for .6 billion.Saddled with debt, the store was not able to pour enough money into necessary, innovative changes. By the time Amazon ruled the online shopping ecosystem, Toys "R" Us was lightyears behind — despite an early partnership with Amazon in 2000. The agreement to jointly sell toys online ultimately went sour and ended after a court fight."Walmart had a better online experience. Target had a better online experience," Silver said. "They lost online and they didn't adapt."In 2015, Toys "R" Us closed its Times Square mega-store. It was the beginning of the end.A dismal 2017 holiday season was the death knell. Toys "R" Us will run out of cash in the United States in May 2018, according to a recent bankruptcy filing."Everything is up for sale," Toys "R" Us CEO David Brandon told employees on a conference call earlier this week. 4609

  

FRANKFORT, Ky. -- Kentucky Gov. Matt Bevin is taking a stand on school shootings after 17 people died in a Florida school this week.It's a societal scourge that's top of mind for Bevin since not even a month has passed since a shooting killed two at Marshall High School in the small western Kentucky town of Benton.RELATED: Trump cites mental health in shooting, no mention of gunsIn a Facebook video posted Thursday night, Bevin called on producers of movies, music, television shows and video games to be part of an effort to “figure out how to try to repair this fabric of America that’s getting shredded beyond recognition.”"Our culture is crumbling from within, and the cost of it is high," Bevin said. "All of you, we've got to step up. We're the adults -- let's act like it. Let's step forward. Let's start a conversation."He also made the more standard overtures to fellow governors, the president and Congress to strike up a dialogue that can prevent future school shootings.Watch the video in the player below.The Associated Press reports Bevin also?told talk radio hosts on Thursday that guns are not the reason for the increase in school shootings. He blamed a culture that delegitimizes life through violent video games, TV shows and music lyrics.Bevin called video games where people kill others “garbage” and said “it’s the same as pornography.” He said “freedom of speech” has been abused by allowing things that are “filthy and disgusting and have no redeemable value.” 1505
