If you got Pennington to find any valuable info when you asked him to develop quantitative analogies between forest life cycles and those of corporations to find some profitable trades you could certainly do the same in finding some numerical formula that could identify trade opportunities by analyzing baseball.
Each team– a stock, the aggregate teams– the market, each player– a corporate division, each salary– an investment made in the division and the company, each relevant performance statistic– a relevant performance statistic. Identify the right decision mix that makes teams perform better over time and improve over time and analyze similarities in companies doing the same.
The greatest liability is also the greatest asset– human decision and performance permeate the game of baseball from start to finish and one could question whether it’s possible to find a truly consistent system as a result. I would argue that this complexity makes it a perfect analogy to market/company performance. It moves based on imbedded and sometimes unexplainable intellect and experience of its participants. The chaotic human decision making process is pervasive in both.
Some books are too clever by half. Anthony Trongone’s Trading in the Footsteps of Sherlock Holmes: Balancing Probabilities for Successful Investing (W & A Publishing/Traders Press, 2010) is one of them. The idea—to encourage traders to adopt an analytical mindset and achieve emotional discipline by relying heavily on quotations from Sherlock Holmes novels and stories—sounded promising, even fun. And fun is a rare commodity in trading books. Although the book started off well, as it progressed Holmes became a less and less useful coach and analogies from detecting to trading became increasingly strained. It’s hard, for instance, to invoke Holmes in a discussion of order types.
Similes and metaphors play an important role in both the internal thought-process of a day trader as well as in communication between two traders. To describe the emotional reactions coupled to the movement of a stock in likeness to a rollercoaster, or to compare averaging down in hopes of breaking even to digging one’s self out of a hole is to use simile to quickly illustrate a particular situation as clearly and succinctly as possible. Every trader uses these analogies, each having his own favorites, and they are used to add structure to an environment that often lacks useful tools for explaining particular occurrences.
