Temple-Inland was the New York Stock Exchange's biggest winner during a down week, soaring after an unsolicited buyout offer from International Paper (NYSE: IP). Temple-Inland isn't welcoming the deal, but it will be hard to sway shareholders against the $3.3 billion cash bid.

There was no material news leading to last week's 26% spike in the shares of Gramercy Capital, but the commercial real estate financier was due for a bounce. Even after last week's run, the shares are still trading for just more than half of what they were in their February peak.

Ariad Pharmaceuticals rose after favorable data came out on its potential cancer treatment. Ariad's ridaforolimus -- an experimental pill-based drug -- apparently preserved the benefits of chemotherapy to extend the lives of sarcoma sufferers. Ariad and marketing partner Merck (NYSE: MRK) plan to push for the treatment's approval this year.

Zion Oil and Gas spewed 18% higher last week. Options activity spiked after the Israeli oil and gas explorer declared a rights offering. The volatile shares have been known to move on positive drilling updates or buyout speculation.

Ebix had a rare weekly gain after the enterprise software specialist for the insurance industry announced that it has repurchased more than a million shares over the past three months. There has also been some welcome insider buying lately. Ebix plans to ask its board to approve an even larger buyback plan once the current one is completed.

It was a great week for these five stocks. Now let's see if they're up for an encore.
