Here are some quotes from the book:
"One would have been profitable, in 12 out of 14 years by employing the "go long on $SPY on the first trading day of the month trading strategy" as against the buy and hold approach of $SPY, which was profitable, for 10 out of 14 years."
"First trading day of the month trader was profitable in 3 out of 4 years, when $SPY had negative returns for the year."
What is the not so great about it?
At first glance, this book can be intimidating in the sense that it appears to have a lot statistics. The book does not include backup to test Kora's theories ourselves
. However, he does mention that they can be made available through request.
Despite the fact that I've taken a number of statistical courses in college, at first I definitely felt like there were too many percentages and 'T-Test' or 'Payoff Ratio' lingo. Luckily, the book will summarize the statistical findings at the end of each study. For example, in one of the first studies, the author concludes that the $SPY fares better on the close of the first day when the last day of the previous month closed down. These tidbits helped me summarize the statistical tables that were presented.
Furthermore, the book does a fairly decent job of explaining what each of the statistical measures represents and how it is being calculated at the beginning of the book.
One of the best things about the book is that all the "best" strategies with the "first trading day of the month" are summarized at the end of the book. Though this in it in itself may not be enough to be a comprehensive trading strategy, it can provide you with valuable insight that may fit into your own trading plan
What is your final recommendation?
