These are hard to predict. However you always have the option to react. The best way to react to news such as chip shortage, fertiliser shortage, wheat shortage, high prices in oil, is to sell once you hear the news. Of course one would need to have bought first before such news arrives, so it’s always good to have a diversified portfolio so that these news will likely hit a small fraction of your portfolio. One can also short sell and play with puts, but it’s more difficult there because you don’t know how fast the price will go down.
