Are Investment Strategies Testable?
Abnormal Returns thinks so. I’m not so sure.
I track net-worth as my how-mi-doing. I feel that’s the most important step, both to beat the mental accounting impulse, and the last-trade bias. I’m not sure that strategies can be “testable” beyond that though. We pass through history once in our lives. The good or bad strategy I had in the 90’s may or may not be appropriate for the 10’s.
