This has merits in a bull market regime. However, we may not in a bull market: history suggests that we will have a deeper bottom within 3 - 12 months. So if you buy stock now, when the market is within 10% of it's peak, and you have to wait for two years for the market to recover to that peak, there's plenty of time for someone to wait for the trough and substantially outperform you. Hopefully you are at least collecting dividends, but 2% is a small solace for spending 30% more than you would need if you were patient for a few months.
