This book is now in reprint. It was written years ago. I read it in the 80's and thus I am recalling from memory. It is most unlikely the book has been updated since the author has passed on. Perhaps it is somewhat on the superficial side, but in a way that can't be helped. I say that because as a market trader, I have used planetary cycles in my endeavor. Every market is different in that each responds in a different fashion to various cycles. For instance the beans respond to Mercury, the cattle to Neptune, and the stock market to other planetary configurations (called aspects). I can state in the most vociferous terms that markets do indeed respond to the planets and their relations to each other. Nevertheless, this book will give the novice some insightful means to do market research.
