Apple is currently worth about $590 billion. It's stock brought down the S&P by about 0.09% for the year. Compare that to last year when the stock brought up the S&P by about 0.8%.
Since the bear market low on March 9, 2009, the S&P is up 204.99 percent, but losing Apple would mean it would have gained just 197.63 percent.
Notably, analysts still love AAPL. Out of 49 brokerages, Yahoo reports that 41 have a position rating on Apple and none rate the stock as "sell". The current median price target for the stock is $145, a gain of nearly 40%.
