the gurufocus link is just reporting the high and low price of the quarter.  price range (average) – the estimated trade prices. the average price   is calculated from the time weighted average during the period. if no   price range is shown, the trade prices are estimated trade prices,   which are more accurate estimates. aapl: $420.05 - $549.03 ($467.26) the numbers for the high and low match what i found for aapl on yahoo finance. keep in mind their definition uses estimate 3 times.
