Bulls Hack Out of a Thicket

The stock market's favorite markers of robust growth were back on the field Thursday, too.

In merger and acquisition activity, Cisco(CSCO) agreed to by WebEx(WEBX) for $3.2 billion, or a 23% premium. Cisco slipped a fraction while WebEx jumped 22%.

Blackstone squashed rumors that the firm would launch a competing bid for Texas utility TXU(TXU) but reportedly said it would join with current equity partners Kohlberg Kravis Roberts and Texas Pacific Group if they needed another equity partner on the $32 billion deal.

Dow Chemical(DOW) gained 5.6% on news the company plans a joint venture with an India-based petrochemical company. Caremark(CMX) added 2.7% ahead of the company shareholder vote Friday on whether to accept a $26.5 billion buyout bid from CVS(CVS) or to wait on a higher bid from Express Scripts(ESRX), which gained 1.6% Thursday.

Copper miners Freeport McMoran Copper & Gold(FCX), Southern Copper(PCU), and Rio Tinto(RTP)l gained 6.7%, 2.8% and 2.9%, respectively.

Oil fell 1% Thursday, to $57.55 per barrel -- weakness that suggests the typically slower spring and summer seasons may be kicking in. The lower oil price spurred a 0.9% rally in the Dow Jones Transportation Average.
