As stock market slide rattles investors, some advice from an expert

NEW YORK (WABC) -- On Friday, the stock market suffered its worst one-day drop since 2008.

For years, investors in U.S. stocks shrugged off threats - a government shutdown, fear of a euro collapse, a near U.S. debt default - and just kept on buying. At the sixth anniversary of the bull market in March, the Standard and Poor's 500 index had more than tripled in value.

Now, buyers are hard to find. A wave of selling has hammered major indexes, with the S&P 500 losing nearly 6 percent in the past week. That is its worst weekly slump since 2011, and leaves it close to what Wall Street calls a "correction," or a fall of 10 percent from a recent high.

Is there more selling to come? No one knows, but corrections are natural in a bull market, a pause in the market's march higher, and this one is long overdue. They usually come about once every 18 months. The last one was four years ago.

What's the best move now for investors? Joining us on Eyewitness News Sunday Morning to shed some light was stock expert Richard Bregman.
