A recent study has found that women tend to choose more conservative strategies while men often favor riskier options.  Parents of young women were more likely to urge them to save but young men were more likely to be educated on wealth building and investing.

"There have been  studies indicating the difference is less about gender and more based on certain attributes like financial literacy and economic backgrounds", is what behavioral finance expert Brad Barber, professor of finance at the Graduate School of Management at the University of California, Davis remarked. 

Women are more interested in security and stabilizers in a household.  Finance has traditionally been a macho domain, as depicted in The Wolf of Wall Street.  Women make up less than 10% of fund managers in the United States, which is a decrease from 13% in 2000.  Men frequently take the lead on financial decisions.

Women's portfolio performance is slightly better (about .4% better) as an annual rate of return.  This is likely because women hold more conservative investments that are less prone to volatility.  Men are more risk tolerant toward gains and women are more risk tolerant toward losses.  As a result, women are better long term investors while men are better day traders.

Of course, research tends to paint behavior with broad strokes.  Many men are conservative investors and plenty of women are comfortable with riskier strategies.  It really comes down to each person's own situation and preferences.
