I disagree here, while there is always a tradeoff between risks and returns and there is volatility, you don't have to gamble on the stock market. You can invest in ways that over the long term have a very high chance of generating positive returns , which is what most people should be doing with most of their money. Pulling out of the S&P500 because it has dropped a few percent is pretty much the opposite of of low-risk strategy, baring people at retirement age or some specific scenarios. It may appear that people are trying to be low risk but by selling they are converting unrealised loss over the last months to realised losses from peak and are thereby exposing themselves to more risk. There is simply no clear ways to know when to buy or sell, the only thing we do know is in 5-10 years it is very likely the S&P500 will be higher than it is now and trying to time when to buy and sell is impossible, so a holding strategy is the best strategy.
