I note also that DB is facing regulatory charges on its brokerage business in Korea and is being accused of market manipulation. See http://community.nasdaq.com/News/2011-03/trading-ban-in-south-korea-has-little-impact-on-db-stock-regulatory-overhang-lingers.aspx?storyid=60183

Perhaps what we have seen here in relation to DB's trading in BOW also warrants a closer look, even if it may not have been illegal. Did it have advance inside knowledge of Arrow's takeover bid, for example?
