Tim has been subjected to much criticism in these reports. He has filed rebuttals and I believe him. This is not n**i Germany and it's no crime to be a Jew. I believe that he is honest about his trades and does not front-run his students. In fact I have noticed that he is careful not to trade against them, however here is an argument he may find difficult to rebut.
Investing in profitable companies means sharing in their profits, but most companies with penny stocks are doomed to fail: at least that's what Tim tells us. Trading in their stocks, therefore, is a zero-sum game and any gain comes at the expense of other traders, not from the companies. Fluctuaction in the price of stocks is not a natural phenominon. It is the result of actions by traders. Tim is teaching his students how to take their money by outsmarting them. Also, would Tim be willing to reveal how well his students are doing on balance?
We know that he has two millionaires and a handful of others who are on their way, but how many are down to their last cent? I really would like to know.
