Do you fall into the hedgehog or fox style of thinking, and how does it impact your investing methods? (The fox knows many things, but the hedgehog knows one big thing.”) Think about this for a moment before answering.
Maybe we are all a little bit of both, but lean more to one side than the other in our thinking processes. As a Mosaic Investor, I like to think of myself as a “fox thinker,” but due to an obstinate nature, particularly when it comes to facts, — well, I might be tugged over to the hedgehog side of the thinking spectrum on occasion.
A “hedgehog investor” is one who knows a method of investing (a big idea) and will stick with it regardless of any evidence suggesting they might be wrong, or at least misinformed. “Hedgehog investors” are reluctant to break with their “big idea” or examine their methods when questions are raised as to its validity. In many cases, it is the lack of evidence supporting the investing method that should raise the flag of warning.

Let’s use an example I followed back in the 1970s and into the 1980s. To my knowledge, this investing method is no longer used so no harm should come to any readers. This timing model was followed by so many investors at the time that a signal to move in or out of the market actually had an impact on the market.
The timing model used no-load mutual funds that permitted one to trade over the telephone. Remember, no Internet was available to T.C. PITS at the time. Here were the trading signals. When one was out of the market, you were to remain on the sidelines until the 200-Day Moving Averages for both the NYSE (It might have been the DJI) and the Dow Jones Transportation averages moved from below to above the moving average. When both averages were positive, one moved all cash into the no-load mutual funds of choice. The service also included mutual fund recommendations. The investor stayed in the market until both the NYSE and DJT averages moved from above to below their 200-Day Moving Averages. These were not Exponential Moving Averages, but simple moving averages. Even though the trading rules were clearly explained, if one did not want to do this on their own, we were welcome to turn our money over to this advisor at a cost of 3% of the portfolio value. I considered a 3% fee for this service to be usury.
Please note – I am not an advocate of the above timing model.
Here we have a “big idea” or a hedgehog approach to investing. Now if one applied a little “fox thinking” one could outsmart this well known investment advice by using Exponential Moving Averages (EMAs) instead of Simple Moving Averages (SMAs). Remember, EMAs are faster moving averages compared to SMAs. Using EMAs one would exit and enter the market a few days before the timing advisor gave his buy or sell signal, thereby avoiding the market move when this “hedgehog advisor” gave his signal. On one occasion, this advanced warning resulted in avoiding a 22% single day drop in the market. Anyone remember “Black Monday” back in October of 1987?
Without getting too specific, there are still “hedgehog thinkers” working the marketing system without providing evidence their investment advice actually works, and by works, one generally means the investing method will perform better than a benchmark. The S&P 500 is one of the most used equities benchmarks in this country so one expects a portfolio will outshine the S&P 500.
A “fox investor” is constantly taking in new information, particularly research that breaks new ground. This investor also has a reliable method for determining portfolio performance and portfolio risk. These two important measuring instruments are wrapped into one important ratio — the Information Ratio. It is unfortunate this ratio does not carry a more descriptive name, but we will go with the common usage.
Perhaps it is a bit of the “hedgehog” in me, but I think asset allocation (AA) is really a “fox” or even “foxy” approach to investing. Combine AA with some technical analysis, tactical asset allocating, mix in QPP analysis and one begins to put together an investing model that can be shown to reduce risk while improving performance. And that is what it is all about.
