Did you know that the data underlying studies of investor behavior in the US is over twenty years old?
“What Investors Don’t Know,” Wall Street Journal, January 24-25, 2015 B8. Brokerages in the US haven’t shared the information they have for one of two reasons: to comply with privacy regulations or to protect their own proprietary data. Because this data hasn’t been collated and studied, there’s no recent analytics of investor behavior. So what your professor’s teaching you about investor behavior is out of date or based on foreign data.
Couldn’t this data be anonymized and analyzed? Don’t we do that with medical data? Isn’t the trending data important outside the individual brokerage? Is this information really proprietary to the brokerage? Who really owns the data? Why can’t this be accessed? Who’s trying to hide what?
