NEW YORK (TheStreet) -- On his Monday Stop Trading! segment on CNBC, Jim Cramer said Exxon's (XOM - Get Report) CEO Rex Tillerson is doing "a lot right" behind the scenes, as the company acquires natural-gas producer XTO Energy (XTO).

"He realizes the shales are bigger than anyone realizes," Cramer said. "I think the XTO move is a move of brilliance."

Still, Cramer laments that Exxon has always been "so biased" against stock buybacks, especially because it has done nothing for the stock.

Meanwhile, amid Monday's stock market rally, homebuilder Standard Pacific's ( SPF) stock price was rising along with Fannie Mae's ( FNM).

Cramer noted this, declaring that Standard Pacific has been going up with Fannie Mae amid an impending housing shortage, as people are being paid to stay in their homes. Given this, homebuilder Lennar ( LEN - Get Report) is another stock to keep an eye on, Cramer said.
