NEW YORK (TheStreet) -- Twitter (TWTR) has been having a rough time keeping up its share price as the social media network fails to significantly grow its revenue and userbase. Fingers have been pointed at Twitter CEO Dick Costolo, but could some of the stock slump be attributed to a lack of female leadership?
While there is a clear gender imbalance across all of tech, Twitter in particular seems to have a difficult time retaining female employees in senior roles. Chloe Sladden, vice president of media, left in August. Vivian Schiller, who was the head of news and journalism partnerships at Twitter, left in October 2014, after just 10 months, and April Underwood, director of product, left in February of this year. There are also rumors of Kate Jhaveri, senior director of consumer marketing, possibly leaving in the near future after having been passed over for the role of CMO.
Just 21% of senior level roles at Twitter were filled by women as of last July, excluding the above departures. At Facebook (FB), 23% of leadership roles are held by women, 21% at Google (GOOG), 20% at Apple (AAPL), 25% at Amazon (AMZN), and 29% at eBay (EBAY).
Twitter did not respond to an email asking for comment.
Gender-diverse companies (in the top quartile for ratio of women to men) are 15% more likely to financially outperform the national industry median, according to a McKinsey & Company study from January. In the U.S., for every 10% increase in racial and ethnic diversity on the senior-executive team, earnings before interest and taxes rise 0.8%.
