People who would make that argument would argue that any assertion that men are inherently different from women (even if the men are different in negative way) is sexism. And that we should treat all people as equally the same and to suggest otherwise would be sexist.

I would argue that by recognizing the inherent difference in the sexes we could create a better more diverse society. By recognizing that male and female investors tend to do better in different economies (men when more risk taking is appropriate, women when risk taking is a bad idea) companies can achieve two important goals: First by diversifying who works for them (the male to female ratio) they can create a better portfolio for their clients because the investment portfolios will do better in a wide variety of economic situations, and second, and perhaps more importantly, they can diversify their workplace.
