August's 10 Worst-Performing S&P 500 Stocks

Historically, not much happens on Wall Street during the last full month of the summer. And, for the most part, that pattern held true in August.

But with the election less than two months away and traders back from their summer vacations, investors can expect things to pick up significantly in the next few months.

For the month, the S&P 500 moved up 27.26 points, or 2%, to finish at 1,406.58.

Here are 10 S&P 500 stocks that greatly disappointed investors during the final month of the summer.
