“Back from my trip west, and getting a look at Apple’s stock performance and the picture is kinda nasty given the life-time high closing point the stock hit on Dec. 28. Since then it’s been a rough ride, as about a third of its value has been erased, most of that on Jan. 23, when it fell $16.57 or more than 10%. Ouch. On a split-adjusted basis, that day qualifies as the single-worst price drop in Apple’s trading history,” Arik Hesseldahl blogs for BusinessWeek.
Hesseldahl writes, “But there have been worse days when you measure the drops by percentage. According to my spreadsheet, Jan. 23 was only the 14th worst percentage drop ever. The worst single-day fall was the 52% drop on Sept. 29, 2000, followed by the 24.37% drop on Oct. 19, 1997.”
Hesseldahl writes, “And as multi-day drops go, this period is pretty close to the worst, but not quite. Over 24 trading says, Apple has lost about 34% of its value, with an average drop of about 1.7% a day. I had to look way back to find a comparable period that was worse, but I found a few that compare.”
