I stopped reading at "I've always like (sic) retail stocks ...". How's that working for him in 2017.? O'Neil has likely made far more money from brokerage commissions, book sales and seminars for retail investors than actually trading stocks (which conveniently are undocumented). Just one more biased perpetrator of the myth that the average joe can make money with any degree of success trading stocks. The vast majority of investors that read his books would have been and still are better off with Vanguard.
