"The odds of outpacing the averages are slim indeed. Consider a new study by Hendrik Bessembinder, a finance professor at Arizona State University. He looked at U.S. stock performance over the 90 years through December 2016.
His startling discovery: The market’s entire 90-year gain, over and above Treasury bills, could be attributed to just 1,092 companies, equal to 4% of all stocks. The other 96% collectively matched T-bills."
"S&P’s most recent analysis found that, over the past 15 years, just 7% of large-cap U.S. stock funds outpaced the S&P 500-stock index, 6% of mid-cap funds beat the S&P MidCap 400 and 6% of small-cap funds outshone the S&P SmallCap 600. The 15-year results for bond funds and international stock funds were almost as grim."
So picking stocks is not best choice for most investors.
