Shares of Apple jumped more than 7 per cent overnight, with one analyst calling a two-month sell-off in shares of the most valuable company on earth insane.
After hitting an all-time of $US705.10 on the day the company launched the iPhone 5, Apple's stock slumped into correction, and then into bear territory, down nearly 21 per cent from that September high.
Topeka Capital Markets analyst Brian White, who sees "insanity" in the stock plunge, believes that the sell-off over the past eight weeks is overdone. He cites new "blockbuster" products for the holiday season - including the iPad Mini - as reasons for buying the stock.
He thinks Apple could grow its earnings per share at a rate of 20 per cent to 30 per cent per year over the next five years. That's based on the company's low market share in mobile phones and PCs, "combined with growth opportunities in tablets and new potential areas such as Apple TV".
That said, the Cupertino, California, company warned late last month that the costs of making new gadgets would cut into profit in its holiday quarter.
On the same day, the company fell short of Wall Street expectations for the second quarter in a row - something that hasn't happened in more than a decade.
Monday's increase is the biggest one-day gain since May 21, when the stock closed up 5.8 per cent at $US561.30.
Shares of Apple Inc rose $US38.05, or 7.2 per cent, to close at $US565.73 on Monday. Even with the gain, the stock is down nearly 20 per cent from the record high of $US705.10 struck on September 21.
