Loss aversion is a behavioral economics theory. That explains the behavior of some people who tend to avoid losses. You could say that some people do not want to incur losses, even if the profit behind those losses is double the potential loss.

The risk aversion here is an act, or you can say it is the risk profile of investors who tend to avoid risky assets. In this case, this is not a bad thing but more about managing assets based on the investor risk profile.
