NEW YORK ( TheStreet) -- Several stocks trading near $5 were moving on above-average volume during Monday's session.

Sirius XM ( SIRI) was up a fraction of a penny to 91 cents on a spike in volume after the satellite radio provider upsized a debt offering of 8.75% notes due in 2015 from $550 million to $800 million. Barrington Research said the increased offer enables repayment of $500 million of 9.625% senior notes due 2013 as well as $244.4 million of senior secured term loan due 2012, with more than $50 million left over for general corporate purposes. The firm added that the positive fundamentals continue to provide the underpinnings for their favorable investment view. Volume topped 108 million shares, compared to the 50-day average daily volume of 94,000, according to the Nasdaq.

Chordiant Software ( CHRD) surged by $1.16, or 30.5%, to $4.97 after Pegasystems ( PEGA) said it will buy the company for $161.5 million, or $5 per share. Volume topped 7.83 million shares, compared to the 50-day average daily volume of 194,000.

IntelliPharmaCeutics ( IPCI) gave back 72 cents, or 17.4%, to $3.42, retracing some of the stock's 166% surge on Friday.
