I was reading a Wall Street Journal column by James Stewart recently. He has a column called “Common Sense” which outlines his approach to selecting stocks and investing. His strategy involves buying when the stock market drops 10% and then selling when the stock market rises 25%. This type of investing (which looks at relative market levels) is a type of “technical analysis” as opposed to “fundamental analysis” which looks at the merit of individual stocks relative to financial metrics. To be fair, Mr. Stewart’s model is a mix of technical and fundamental analysis, but the “buy”and “sell” signals are pure technical analysis (in my opinion).
The headline of the article really caught my eye, however:
When bad times get worse, it’s best to stick to a system
That quote reminded me of a line from one of my favorite investing books titled “A Random Walk Down Wall Street” by Burton Malkiel. On p146 he discusses his opinions of technicians which rings eerily familiar:
I personally have never known a successful technician, but I have seen the wrecks of several unsuccessful ones. Curiously, however, the broke technician is never apologetic. If you commit the social blunder of asking him why he is broke, he will tell you quite ingenuously that he made the all-too-human error of not believing his own charts
