Hi, I'm New here, so please be gentle. First I work in the Egyptian Stock Market (CASE) And I have three cases that I can't edit the data for. The first case is A Stock that offered general subscription for former holders of that stock, and the subscription is 2 stocks for every original stock with the fee of 5 pounds/stock, The Closing price in the last day before subscription began was 128.45, , after moving the price Limits (128.45+10)/3 = 46.15, the closing price equals 46.15 pound. How can I adjust the older data? Someone suggested making a distribution of (-10) and then split it 3 for 1 until the last date of old prices. The second case is almost the same, a Stock which offered general subscription for former holders, 1 new stock for every owned original stock with the fees of 5 pounds/share. The Third case is a stock that offered general subscription for former holders, 6.7 new stocks for every 100 owned original stocks with the fees of 201 pounds/share. Please Advice on how to edit the old data to fit the new prices.
