I am not sure of the scientific correlation between addictive personalities and stock trading, but anecdotally I have seen many of the same people that suffer from addiction to gambling or alcohol also are addictive stock traders.

I have a very good friend that falls into this category and he is always making trades.  He plays options and is constantly doing a deal.  Unfortunately, he also has an alcohol problem.

While this is is not scientific evidence it probably does lend itself to some investigation.
