OT: That's not true. The term "Past performance is no guarantee of future returns" is a cardinal rule of investing. The reason for this is because it has been proven true time and again.
If an investor could use past performance to beat the stock market, then we would not have an efficient market. Everyone would do it. Finance theory calls this the "weak form" of market efficiency.
I submit that using dart-throwing (a method famously used by John Stossel from 20/20) is equally as effective as using TA.
Of course this is my opinion, but its an opinion grounded in solid research in the field of Corporate Finance.
