 And so once your portfolio gets too far out of certain thresholds, you want to automatically rebalance that both when the stock market's down and when it's up. And so, you know, we rebalance, we're selling bonds and buying stocks during COVID when the stock market was down, that turned out to be a great move. It wasn't our genius. It was our rules. And then conversely in 2021, when stocks were up so much, we were selling stocks and buying bonds. And so it's especially for you people in retirement, you need to make sure your risk reducers are actual risk reducers. And when you're rebalancing, you're rebalancing to make sure that you're managing risk. Those are really, really important things.
