“a single firm showed”
You almost accidentally got a fact right. it was ONE firm, Fidelity, only one of the largest trading houses on the planet and their results were backed up by the other trading firms (though they refused to give exact stats only said that it seemed “about right” in interviews following).
The problem is that the results were confirmed by another “firm” which is a trading app, only one of the most globally used trading mobile trading apps with trillions of dollars in processed trades and they came up with numbers that were very similar to Fidelity’s. So not exactly “one firm” you can’t even accidentally get your facts straight.
And yes, you’re right, individually we can (and do) deviate from “norms” … but that wasn’t the question I posed in the OP now was it. The question I posed is that given that women are IN GENERAL better traders than men, why aren’t there more female traders.
The question had nothing to do with a specific individual. Sheesh.
