example of a really good answer:
Distinguish between idiosyncratic and systemic risk.

Idiosyncratic risk is the risk that results from owning a specific security in the form of a stock, bond, CD, etc. It is the risk you think of when you think about losing money investing in a specific thing. For example, if you bought a share of AMZN, and then earnings came out and they were disappointing and the stock price falls resulting in you losing money, you just suffered the consequences of idiosyncratic risk. You can diversify against idiosyncratic risk by purchasing many different securities so that when one does poorly, it doesn’t affect you as much because the others are likely to not be suffering the same problems.
Systemic risk, on the other hand, is risk that affects many securities at once. These are often geopolitical events that result in the market as a whole being affected. For example, a highly infectious virus might originate somewhere in the world and start to spread aggressively causing economic slowdowns/lockdowns that in turn affect the performance of many securities at once. These sorts of things are generally out of the hands of individual investors, and cannot be so easily diversified against.
