How Men’s Overconfidence Hurts Them as Investors
There’s been a lot of academic research suggesting that men think they know what they’re doing, even when they really don’t know what they’re doing…
MEN and women invest differently, a growing body of research has found. And in at least one important respect, women may be better at it.
The latest data comes from Vanguard, the mutual fund company. Among 2.7 million people with I.R.A.’s at the company, it found that during the financial crisis of 2008 and 2009, men were much more likely than women to sell their shares at stock market lows. Those sales presumably meant big losses — and missing the start of the market rally that began a year ago.
Male investors, as a group, appear to be overconfident, said John Ameriks, head of Vanguard Investment Counseling and Research and a co-author of the study. “There’s been a lot of academic research suggesting that men think they know what they’re doing, even when they really don’t know what they’re doing,” he said.
Women, on the other hand, appear more likely to acknowledge when they don’t know something — like the direction of the stock market or of the price of a stock or a bond.
