Buy only one or a few stocks at the low enough price. If the price goes up, wait until you have significant profit before adding some more. The unrealised profit protact you from too much loss if the price goes down.
If the price goes down after you bought one or a few shares, wait until the price hit the bottom or went low enough. Buy Call Option.

MaNameJeff : Tariff talk is problematic, seems any little miss will make the market tank. Depends on your risk tolerance
