Apple, which sold more than 5 million iPhone 5s in the first three days the smartphone has been available, is on a record-breaking sales pace but that doesn't appear to be enough for Wall Street.
Apple shares are down more than $9 to about $691 Monday morning, apparently because the weekend sales figures were less than what analysts expected.
The phone launched Friday in nine countries around the world including the U.S., and sales should stay strong as it readies to launch in 22 more countries this Friday.
But the demand may be outstripping supply, worrying investors. If you try purchasing the phone through Apple's website, the company now says there's a three- to four-week wait time for the iPhone 5.
