OptionMonster's Pete Najarian said he remained bullish on Apple stock, not taking a guess what new products Apple would release next month.
"I'm not really sure, but I rolled out of the 460 calls in August today, rolled up to the 500 in September," he said. "The reason I did that was, I was looking for areas where I'm seeing the most unusual activity. Looked like there was a fair amount of activity to the upside, the 500 strike was very active."

Stuart Frankel's Steve Grasso wasn't a buyer of Apple stock at current levels.
"I think it's a little long in the tooth," he said, noting that the stock was trading below its 200-day moving average of $471. (Apple shares closed at $467.36, up 2.84 percent.)
"Great spot to take a stall, take a breather in the name, and you've seen money coming out of Google, into Apple and Facebook," he added.

Tim Seymour of EmergingMoney.com was bearish, adding that he was focused on what Apple wasn't doing in emerging markets.
"Right now, it looks tired," he said.
