Fascinating study from Harvard Business School's Boris Groysberg showing that women star stock analysts are more likely than men to maintain their star power when they switch companies.

The study How star women build portable skills found that unlike their male counterparts, female stars who switched firms performed just as well, in the aggregate, as those who stayed put. Furthermore, it might also be better for the company that recruited them. Maybe. Firms acquiring male stars experienced a share-price loss whereas the acquisitions of female stars generated a share-price increase, although when you look at the numbers themselves, they are pretty small to be significant.

Groysberg argues that it's because women have more portable skills. Whereas men focus on the power relationships, women are more inclined to develop networks with clients and contacts at the companies they cover. Women were also more likely to have mentors. Women are also more likely to look at a variety of factors, like does the organization welcome them as an individual, when making their move. Men, on the other hand, focus more on compensation.

The study's findings are interesting because they suggest that women have had to make these adjustments because of attitudes and road blocks when they entered the workplace. When you're more likely to get laid off in a downturn, when you are not part of the boys' club, these adjustments are necessary. And career building.
