No, I don’t think it makes sense to change the meta strategy allocation each month. The problem is that if you would for example change from the Nasdaq 100 strategy to a safer strategy like Bond Rotation, then you profit only half if there is a recovery. It’s like selling half of your Nasdaq100 allocation and go to cash. This means that you realize a loss with no chance to recovery. The Nasdaq 100 strategy had a lot of such one month draw downs but it had even more really big monthly gains with single stocks surging 20% or more.
However due to the high valuation of the Nasdaq100 and the normally underperforming summer period I would not invest too much in the Nasdaq100.
