NEW YORK ( TheStreet) -- For the first time in its history, Apple's ( AAPL) iPhone 4S was surpassed by a competitor. Could this be hurting Apple's shares? Apple's share price has come under pressure recently, on concerns of lack of innovation at the Cupertino, Calif.-based giant, as well as fatigue. Consumers are flocking to the iPhone 5 in droves, and it's still extremely difficult to get one. Shares are off 14.36% over the past month and 11.83% over three months, compared to a 5.87% and 2.72% decline in the Nasdaq. Samsung's Galaxy S III surpassed iPhone 4S sales in the third quarter (August), according to research firm Strategy Analytics. Among the reasons cited were " a large touchscreen, extensive distribution and generous operator subsidies.." Samsung sold 18 million units of its flagship smartphone, with Apple reportedly only selling 16.2 million units of the iPhone 4S. Apple also sold 6 million iPhone 5s during the quarter. "Apple shipped an estimated 16.2 million iPhone 4S units worldwide for second place, as consumers temporarily held off purchases in anticipation of a widely expected iPhone 5 upgrade at the end of the quarter," said Neil Shah, senior analyst with Strategy Analytics. Shah added that he believes Apple will regain the crown in the all-important fourth quarter, with the iPhone 5 launch going extremely well. Apple sold 5 million units of the iPhone 5 in its first weekend.
