Turning points is a theory based on Min-Max analysis. Barring bankruptcy, and any other unforeseen situations such as fraud like in the case of Enron and Worldcom, all stocks have a base price which can be determined by using the financial statements. Total share holder's equity, working capital, market cap multiple to sales, etc, can all be used to determine a stock's base price. Likewise, these ratios can also be used to determine a stock's top price based on the stock's historical averages and comparable against other companies.
In mathematics, most continuous functions have a min-max property. Stocks can be likened to smooth continuous functions, and in any stock chart it could be seen that these min max properties do appear in the charts. I think it is this belief that has shaped my investment philosophy.
As stated earlier, barring bankruptcy, I want to make a purchase at a min price and exit the position at a max price. Or alternatively, short a company at a max price and exit the position at the min price. This approach to investing implies the following:
- IPOs are avoided
- Research companies, such as bio medical companies with no financial statements, would be avoided
- Stocks making new 52 week highs and new 52 week lows would be avoided.
With regard to IPO's, there is no historical price pattern to base a min-max decision on. With respect to research companies, there is no meaningful financial information to compute ratios. And with respect to 52 week highs or lows, the max or min is yet to be formed.
This would imply that my investment candidates would consist of mature companies or new companies that have been trading for at least one year, and I should focus on companies that are range bound and have a well determined min and max.
This analysis would explain my continued persistence in buying companies that are dropping in price and selling near their min point, and my constant shorting of companies making new highs near their previous high point. While this may sound like a great idea, in general practice this is a recipe for disaster!
From a market perspective, it implies buying companies the market is shunning (i.e. RIMM, BBI) and shorting market darlings (i.e. AAPL, NFLX). From an economics perspective, it implies buying companies with decreasing market share (YHOO), and shorting companies with increasing market share (GOOG). From a financial perspective it implies buying companies with decreasing profit or even loses (AMD), and shorting companies with increasing profits (INTC). Overall it, implies being a contrarian!
Min-max is great for mathematics, but if applied literally to stock investing it leads to losses instead of profits. In reality one wants to ride the bull and short the bear. Literally this would mean buy at the max and short at the min! This is what actually works in real life. Old mins get breached and go lower, and old max get breached and go higher.
In a way, investing requires a lot of optimism. It requires blind faith to believe that something that is going up will continue to go up and something that goes down will continue to go down, which in our gravity bound world does not work all the time!
After all, this blind optimism leads to tulip mania, dot com mania and housing mania. All of these manias have at their heart the greater fool theory in common. As Charles Prince, the ex CEO of Citigroup once said, "as long as the music is playing, one needs to keep on dancing". So keep buying as long as one is not the greater fool making the last purchase at the highest price!
Is it possible to reconcile min-max theory with the market reality? Perhaps it is, and I need to give it some thought. Eventually min-max does work. Stock prices don't continue going up forever, and eventually, aside from bankruptcy, most companies do have a bottoming out price at which they either recover (AAPL, F, YHOO, EBAY) or get bought out by other companies (PALM, SUN). The secret of applying min-max theory to stock investing would be determining how to avoid companies that either go bankrupt (GM, BBI, LEH, WCOM, ENRON) or get take under offers such a Bear Sterns.
