You're thinking about your personal investments, not someone managing a large investment firm or hedge fund. This simple fixes for your personal investments would be seen as absolutely insane in the professional investment world. You can't just tell your clients "oh I put $100 Billion into some nearly 0% interest investments because I think the market is crazy", especially if the DJIA is having record months. Even the people managing your 401k are expected have a steady read of return and react slowly and calmly.
