Financial risk management

Ever worried about losing more than just your shirt in a bad investment?

Imagine you're at a carnival, betting on games with a fixed amount of money. You want to know how much you might lose if you bet too much.

You're looking for a way to measure the worst-case scenario, not just the first loss you'd face. It's like asking, "What's the worst I could lose if things go south?"

Example

You bet 100 on a game with a 50% chance of winning 200. Traditional VaR might say you won't lose more than 50 on average. But if you lose, you lose all 100. CVaR tells you the average loss if you lose, which is $75 in this case.

Remember this

CVaR helps you understand the true potential loss, not just the average loss.
