Editor's Note: Jeffrey A. Hirsch is editor-in-chief of the Stock Trader's Almanac, which popularized the "Sell in May" market strategy. On Oct. 6, Hirsch told CNBC Pro his technical analysis gave a 'buy'' signal on the market. The S&P 500 went on to gain 5 percent.
Seasonal trading and investing patterns and strategies are now in vogue. Just a short time ago, market seasonality and other forms of financial technical analysis were considered esoteric and trivial.
Now, not only is it acceptable to discuss and use technical analysis, it is expected and sought after. Practically everyone on TV has a technical chart, historical seasonal pattern or comparison to prove their point. I say welcome aboard.
At Hirsch Holdings and the Stock Trader's Almanac, we have been relying on seasonality and technical analysis for six decades.
While many market participants are hip to the saying "sell in May and go away," most forget to get back into the market in the fall. And we learned that you shouldn't just buy blindly at the end of October, something last month's rally made clear.
