I raised a probably same issue in another post today. After the stock split, the shares original price are not adjusted accordingly. Regards

Sorry, the stock in question is Amazon's. The original cost before the 1/20 split was 1818.20 US which when divided by 20 is is 90.91 US$. A recent price of 91.16 is close, not the current devaluation of over 95,02%. The main problem with this is the distortion in the whole porfolio. Sorry for my earlier mistake. Can you help? I think that in the future should not be difficult to have the original stock prices divided by the split number. 

Help? All the best.
