Check Point ( CHKP - Get Report) fell Monday after RBC Capital Markets analyst Robert Brez affirmed outperform with a $65 target price, citing difficult economic environment for software companies in general.

Most software companies "have a lower pipeline today than going into the quarter, reflecting some pull-forward of deals, which could lead to a tough start to the September quarter," Breza wrote.

"The deal environment for most software companies was characterized by smaller deal sizes and lower close rates," he added.

Check Point's stock closed down 4.89% to $44.96 on 4.5 million shares, nearly double its average daily volume.
