TA25 closed at 822 on Friday. Yahoo now says it is up 3.2% but the value is 772. Now I only have a 3rd grade education, (and never underestimate a 3rd grade education!!) but it seems to me that 822 X 1.03 is not even close to 772....
Edit: Interestingly, Bloomberg gives the same value. Something is fishy here...
Edit 2: Mistery solved, Yahoo data (as I already knew) sucks!! It really closed at 748 on Friday.
