Too many retail market players don't know what is too good to be true(me? Between March - April 2011, I was one of them!). Now I thought I know but in case someone don't know, I just list some examples below: Example 1: In 1999 Amerindo Technology Fund rose an incredible 248.9%. Its portfolio manager Alberto Vilar ridiculed anyone who dared to doubt it. To him the Internet was a perpetual moneymaking machine: “If you’re out of this sector, you’re going to underperform. You’re in a horse and buggy, and I’m in a Porsche. You don’t like tenfold growth opportunities? Then go with someone else.” How about this fund now? You could guess. Example 2: • Did you know the fever of funds about internet? In February 2000, hedge-fund manager James J. Cramer asserted that IT companies “are the only ones worth owning right now.” These “winners of the new world.” They “are the only ones that are going higher consistently in good days and bad.” “You have to throw out all of the matrices and formulas and texts that existed before the Web. . . . If we used any of what Graham and Dodd teach us, we wouldn’t have a dime under management.” Where is he now? I don't know but most of his clients had lost their shirts between 2000 -2003. *** How many retail market players ridiculed "Warren Buffet" as a man out of date? How many retail market players cursed his self interest? These market players don't understand "consider self-interest" in the market is the basis of market intelligence. How many intelligent retail market players are here? So far I could not see anyone(including myself) is intelligent enough! *** When too many people in the market claim that the next “sure thing,” good or bad, the market tends to go towards to the opposite. It doesn't matter it will be health care, or energy, or real estate, or gold. If your head becomes hot, you should let it cools down. If your head is too cold, you need the guts to check the reality and find the opportunities. Could you hear crying at the peak such as IT booming or that before GFC? Don't follow the crying and cheering but using your brains for wisdom and intelligence.
