Among the companies with shares expected to actively trade in Tuesday's session are Texas Instruments, Agrium and Blue Nile.

Texas Instruments Inc. (TXN) narrowed its second-quarter guidance around its prior midpoint--the first time in about a year the company has done so as business rebounds from its recent lows.

Agrium Inc. (AGU) said it expects its earnings for the first half of the year to be at or near the top-end of its expectations, pointing to strong results across its crop-input business.

Online jeweler Blue Nile Inc. (NILE) said it hired Julie Yoakum as its newly titled chief merchandising officer, replacing Senior Vice President Susan Bell, who is retiring this month.
