When I first started investing years ago, I had the "help"
of a financial advisor who put me up with a market timing strategy. Supposedly, their system would get the signals when to move in and out of the market. After having that active for a few months, I decided to end my relationship with the advisor.
Think about this way, if they could really accurately time the market, why don't every just do it and let their systems take over easily make tons of money? The answer is just because they "have a system", it doesn't mean the system works consistently, if at all.
