Jim Cramer says Apache Corp. (APA) is his "No. 1 Angry Name" because the oil company has shed some 30% since he bought shares for his charitable trust.

Cramer told a conference call with members of his Action Alerts PLUS club for investors that he loves Apache's assets (especially a major Texas oil find called the "Alpine High"), but that the market keeps ignoring the company's positives.

"Do you know that [the Alpine High] is very for real?" he said. "They are spending fortunes developing pipe to take it out of the ground, but nobody cares. And I mean nobody, even though everyone was crazy about it when the stock was in the $60s and the price of oil was below here."
