CNBC’s website today had adjacent links to stories about the market. One strategist was forecasting a higher target and felt the market would stay overbought, and the other strategist felt the S&P; could correct 15-20%. I might feel marginally better if either strategist had statistical evidence that one outcome was more likely than the other, but nothing at all was offered. They are simply opinions. A less formal term would be “guess.”
This is the problem with forecasting—people take it seriously and base investment decisions or asset allocations on guesses. I fail to see how this is going to help anybody invest in the long run. Sure, you might have a lucky guess here or there; after all, one of these two forecasters is going to be right about this situation since they have opposite opinions.
Relative strength is not based on guessing. It is based on math. That doesn’t mean it is never wrong; in fact, it can be out of synch for extended periods. It is just that historically there has been a long-term tendency for markets to follow strength. If we identify the relative strength mathematically and keep rotating to it, we hope to benefit from that long-term tendency of markets.
