Shares of MetroPCS Communications gained as industry news had some investors betting that there may be consolidation in the wireless business, perhaps with Sprint Nextel snapping up other companies. Leap Wireless International pledged to consider all possible strategy changes. Net losses every year since 2006 and $3.2 billion in long-term debt have pushed Leap’s shares down. Leap rejected MetroPCS’s $5.5 billion bid to acquire it five years ago. But an analyst from Near Earth investment bank in Stamford, Conn., said MetroPCS remains a good fit for Leap. “Their spectrum is very complementary,” he said. “A buyer who bought Leap could be interested in both. They’d make a great combination,” the analyst said. A spokesman for MetroPCS declined to comment on takeover speculation.
