What is the ROI on a stock purchased for $87.24 per share a few years ago, that now has a price of $62.56 per share?

Answer 1

This is the formula (End Value - Beginning Value) / Beginning Value. So, for your question (62.56 - 87.24) / 87.24 = - 28.28%. Hence, currently the stockholder is down 28% on his or her investment.
