NEW YORK (TheStreet) -- Shares of Boeing Co. are up 1.51% to $131.70 in pre-market trade after the aerospace company increased its earnings guidance for the year as its second quarter earnings climbed 52%, supported by continued strong demand for the company's jetliners as well as aggressive cost-cutting, the Wall Street Journal reports. The company raised its per-share earnings estimate for the year to $7.90 to $8.10 per share, from its earlier view of $7.15 to $7.35. The increase reflects $408 million in tax benefits, its strong operating performance and a $272 million charge tied to the KC-46A Tanker program, the Journal noted.
