Hansen-Jagannathan bound
Okay kiddo, have you ever heard of a superhero called Superman? He's super fast, super strong, and super awesome. But just like Superman, we want our investments to be super awesome too. That's why we have something called the Hansen-Jagannathan (or HJ) bound to make sure our investments are super good.
Now, imagine you have some money and you want to invest it in the stock market. You have a few different stocks to choose from, like Apple, Nike, and McDonald's. But how do you know which one to pick? You could just guess, but that's not very smart.
The HJ bound helps us figure out which stock is the best choice. It looks at the risks and rewards of each stock and compares them. The HJ bound is like a special tool that tells us how much risk we need to take on to get a certain reward.
For example, let's say we want to get a reward of 10% on our investment. The HJ bound will tell us how much risk we need to take on to get that reward. Some stocks might be really risky and we would have to take on a lot of risk to get that reward. Other stocks might be less risky and we wouldn't have to take on as much risk to get the same reward.
The HJ bound is important because it helps us make smart investment decisions. We can use it to compare different stocks and see which one is the best choice for us. It's like having x-ray vision, just like Superman!
