You Cannot Time The Market
I’ve heard that nobody can time the market. I have heard that over and over. I have heard it from academics in love with their finance theories inclusive of Efficient Markets / Random Walk. I have heard it from supposed investment experts who hide behind buy-and-hold and index investing as a way to collect fees. Mostly, I have heard that you cannot time the market from people who have either never tried or who tried and failed and then gave up.
Additionally, I have been told that I’d lose credibility if I ever claimed I could time the market. If making a statement that goes against “common wisdom” impacts my credibility more than the facts surrounding my techniques and performance, then so be it.
For now, I’ll let you decide what “success” at timing the market means. Does it mean that you have to be 100% correct every instance? Does it mean that you have to outperform by 10%, 20%….100% compared to just following the market?
All the times I have heard “you cannot time the market”, I have never heard how they precisely define success or failure at that pursuit.
Since this site appeared on the Internet in January of 2005, I have offered the HEDGEfolios Timing Indicator as my primary indicator for market timing.
Here are 34 dates where I said the market’s direction was turning during the past 5 years:

I challenge anyone to actually compute the performance of either or both of those data sets. You decide if that proves or disproves whether it is possible to time the market.
