A Stock Point is a virtual reward that tracks the price of a share. When you shop at a participating merchant or buy a product from an eligible brand, you earn Stock Points based on the value of your purchase and the deal amount. 100 Stock Points is equivalent to 1 share of the same company.
This means that the value of your Stock Points will change in the same way that the real share price changes. If the share price goes up, the value of your Stock Points will go up. If the share price goes down, the value of your Stock Points will go down.
