I was expecting alot more from someone referred to as the foremost authority on seasonality in the futures markets. While I give Jake alot of credit for bringing greater visibility to seasonal trading strategies through his earlier research from the late 70s on, this book was somewhat of a disappointment. My first concern is that a large portion of his data modeling is based off of cash market data. While this often allows one a much greater data pool to tap which in turn can assist in lending statistical significance to apparent patterns, I have to question the validity of this approach since as most traders know, futures prices often diverge significantly from those of the cash market. There are no clear trading rules elucidated for particular seasonals, and individual contract months are not well touched on. In addition, while technical filters are mentioned, there is no clear integration with seasonals. For anyone actually interested in trading seasonals with very clear rules spelled out with specific seasonals based on individual contract months, I would highly recommend John Momsen's "UltraReliable Seasonal Trades." While I haven't traded Momsen's methods long enough to draw a 100% conclusion, I've already made significant profits with his systems. This text didn't add enough workable knowledge to warrant the price IMHO. It does however provide some decent info on performing your own seasonal research by data mining...
