Yahoo finance inaccurate stock data


Why is Yahoo Finance historical stock price data inaccurate? See examples: AAPL - actual closing prices in 2012 when AAPL previously closed > $100/share adjusted for 7:1 split; chart & data do not agree, esp when picking different time periods, e.g. "Max" vs "5 year" vs 'Custom". Historical data is also incorrect. These closing prices are wrong:


Sep 21, 2012 95.12 
Sep 20, 2012 94.93
Sep 19, 2012 95.39

NASDAQ



Similar inaccuracies, look at charts & historical data for peak close in March, 2000 > \$5000 when Yahoo data reflects correct closing prices but Yahoo charts never get above $3100.


Apparently discrepancies are rampant..
