I have stock data starting in A1 and continuing down to A7. I am calculating return A1/A7-1. However, each month, a new piece of data will appear. So once August starts, I will then have a piece of data in A8. When Sept starts, I will have a new piece of data in A9. Is there a way to update my formula each month automatically so that it will then calculate A1/A8-1 in August and A1/A9-1 in Sept??
Thank You
