The third-quarter earnings of Apple, the computer and iPod maker, is estimated to have jumped 38 percent, according to a consensus forecast published on Monday.

Apple is expected to publish the report after the closing bell Monday. Earnings are estimated to have jumped 38 percent from a year earlier, to 86 cents a share, on sales of over 6 billion dollars, according to the consensus forecast compiled by Thomson Financial, an arm of The Thomson Corporation, one of the world's leading information companies.

In July, Apple said it would earn 65 cents a share this quarter-- 21 cents below current expectations. Investors will be watching for specifics on iPhone, iPod and Mac sales.

Apple shares have more than tripled in 15 months, and some analysts have raised their price targets for Apple shares to 200 dollars.
