Black's approximation

Black's approximation is a mathematical formula used to value stocks and other investments. It's a way of estimating how much something is worth by looking at how much investors are willing to pay for it and what they think it's worth. The formula takes into account things like the amount of money that people have invested in the stock, how risky the stock is, and the chance that it will make a profit. Black's approximation is used to help people figure out if an investment is worth buying or not. It's like a grown-up way of helping you decide if something is a good idea or not.
