Seriously, if the stock market is going to plunge, Pepsi stock is also going to plunge. The simplest way to reduce your exposure to the stock market is to shift assets toward cash: sell shares, keep dollars, maybe in the money market rather than just as cash. Dollars are exposed to the risk of inflation (hyperinflation hasn't happened yet in the US but it's so common that https://en.wikipedia.org/wiki/Hyperinflation doesn't even attempt to list all historical episodes of hyperinflation, just dozens of notable ones) so investors commonly try to move to metals to balance that risk. Cryptocurrencies have emerged as an alternative, and they have the advantage of being more portable in emergency evacuation situations.
