Deutsche Bank analyst Karl Keirstead cut his price target for MicroStrategy shares to $150 on reduced margin assumptions following the company's presentation at his firm's conference. MicroStrategy provided details on its plan to accelerate spending in 2018 as it looks to boost revenue growth, Keirstead tells investors in a research note. He believes the commentary suggests margins will indeed move into the single digit range. He notes that on its Q2 earnings call, MicroStrategy warned operating margins would decline to 5%-10% "if necessary." Keirstead keeps a Hold rating on the shares.
