A decent flow of contracts from the Pentagon along with a couple of divestment and acquisition deals in the past week should have aided major defense contractors’ share price performance. However, the U.S. stock market ended on a disappointing note last Friday, after a COVID-19 aid package proposal worth $900 billion was rejected by Senate Republicans.This might have marred growth of defense stocks and caused major indices of the Aerospace-Defense space to end in the red zone over the trailing five trading sessions. The S&P 500 Aerospace & Defense (Industry) index lost 1%, while the Dow Jones U.S. Aerospace & Defense index slipped 0.6% in the aforementioned time period.Among the past week’s highlights, defense majors namely Lockheed Martin LMT and Bell-Boeing, a joint-venture between Textron’s TXT Bell unit and The Boeing Company BA secured a number of notable deals from the Department of Defense’s daily funding session. Moreover, Leidos Holdings LDOS signed an acquisition deal while Northrop Grumman NOC divested one of its businesses.Recap of Past Week’s Important Stories1.
