Most leading technology stocks turned their back on early-session losses Monday as the sector awaited the latest quarterly results from Apple Inc. and Texas Instruments Inc.

The tech-heavy Nasdaq Composite Index (RIXF) added more than 17 points to 2,174, while the Morgan Stanley High Tech 35 Index (MSH) and the Philadelphia Semiconductor Index (SOX) each rose more than 1%.

Gains came from Dell Inc. (DELL), Oracle Corp. (ORCL), Google Inc. (GOOG), IBM Corp. (IBM), Cisco Systems Inc. (CSCO) and Hewlett-Packard Co. (HPQ).

Much of the spotlight later in the day is expected to be on Apple Inc. (AAPL) as the company is scheduled to deliver its fourth-quarter results after the market closes. Apple's shares rose 75 cents to $188.78.

Analysts surveyed by Thomson Reuters expect Apple to earn $1.42 a share on $9.2 billion in sales for the quarter. Sales of the iPhone are expected to gain much of investors' attention.

TI (TXN) shares rose 55 cents, or 2.4%, to $23.30 ahead of the communication-chip maker's third-quarter results, due after the market closes. Wall Street analysts estimate that TI will report a 17% drop in its quarterly sales compared with the same period a year ago.
