Keeping Score on Apple Finance Predictions

Philip Elmer-DeWitt:

In our ranking of the best and worst Apple (AAPL) analysts for Q1 2011, which lists them based on how accurately they predicted seven key numbers — revenue, earnings, gross margins and unit sales — the unaffiliated analysts (blue in the chart at right) took 9 out of the 10 top spots.

The bottom 20 spots were all held by professionals working for the banks and brokerage houses. Taken as a whole, the numbers they sent their paying clients were off by a margin (9.04%) more than twice as big as those generated by the guys who do it for free (3.94%).
