Overbought/Oversold: Two Risky Words
The short term Overbought/Oversold indicator, which is avidly followed by some public investors, is a 10-day moving average of advances and declines in the market. Caution: Sometimes in the beginning of a new bull market the index will appear substantially overbought because it has just come out from a long decline. This should not be taken as a sign to sell stocks. A similar occurrence can happen in the early stage or first leg of a major bear market when the index becomes unusually oversold. This event is really telling you that an eminent bear market may be beginning.
What you learn from years of trying experience is generally more important than the opinions and theories of experts using their favorite indicator. Sometimes, the more widely quoted and accepted the market or economic expert, the more trouble you might, on occasion, get yourself into. Who can forget the expert who in the spring and summer of 1982 insisted that government borrowing was going to crowd out the private sector and interest rates and inflation would soar back to new heights? The exact opposite happened; inflation broke and interest rates came crashing down. Conventional wisdom is rarely right in the market.
