 Apr15 comment Forward Adjusting Stock Prices? @bill_080: thank you. the need to re-calculate all data is exactly what I want to avoid. Because in such a case, 'past' indicators / calculations become meaningless when you back-adjust. forward adjusting keeps everything in-tact, although, as you say, the 'price' is not the actual traded price. I have the same question regarding 1-min intervals forward adjustment, and hot it will / should influence the correctness of end-of-day figures. I will ask it as a separate question, pointing to this one as a reference. thank you. Apr15 awarded Scholar Apr15 comment Forward Adjusting Stock Prices? @bill_080: thank you. so it appears from your example that my forward adjusting method does work in all situations (including splits / dividends). do you see any situations where it won't work? any pitfalls? Apr15 accepted Forward Adjusting Stock Prices? Apr15 comment Forward Adjusting Stock Prices? @bill_080: yes, I meant "print close". Apr15 comment Forward Adjusting Stock Prices? @bill_080: thank you. My question is this: suppose that on interval = 6 the stock splits 3-for-1. and say that the return from interval 5 to interval 6 is given to us. Do you agree that this method of adjusting the prices forward would still be valid? same story when there's an X-dividend: if we have the return (from date x to date x+1, where the X-dividend takes place), do you agree that this method of forward adjusting would still hold true? Apr15 comment Forward Adjusting Stock Prices? @bill_080: this is a general question on how to best forward adjust stock prices; obviously, the actual calculations will be done programatically (using a language such as c++/ python etc). the key is how do you forward adjust stock prices?
