Does anyone use these? Anyone know whether any of them produce better results than just a buy and hold? Even if normally buy and hold is better, I would bet moving average systems would produce much lower drawdowns, particularly when the market is sky high like it is now. Seems like with a moving average, once the price starts to dip, you cover, and don't uncover again until maybe many percentage points more to the downside, thus hopefully missing the next bear market in large part. I'm trying to read up on these, but most don't seem to be all that great off hand. Anyone have any thoughts? Thanks!
