Does regret lead to bad investment decisions?

The decision to sell a stock, for example, should be based only on the stock’s current price and expectations about the future – not on its historical prices. For many, however, selling a stock for €1,800 that just a few weeks ago was trading at €2,000 feels like a loss, and they are reluctant to realise this loss by selling the stock.

The findings are reported in a paper in the journal Nature Communications by researchers including Marta Gonzalez, an assistant professor of civil and environmental engineering and engineering systems at MIT and lead author Zoltan Toroczkai and Yihui Ren at Notre Dame.
