After the worst one-day decline in U.S. history -- "Black Monday" in October 1987 -- Americans were unclear on why the stock market had unraveled.
Slightly more than half of Americans (52%) say they currently have money invested in the stock market. This matches the low first reached in 2013 for Gallup's 19-year trend.
Thirty-five percent of Americans favor real estate as the best long-term investment choice, a four-percentage-point gain from last year that moves it further ahead of stocks (22%), gold (17%), savings accounts (15%) and bonds (7%).
