Aston Martin CEO steps down and replaced by CEO of AMG. As investors, we look for opportunity to make quick trades as well as look long term. I would not invest in Aston Martin long term, but I see value to taking advantage of good news and market reactions. I purchase shares of Aston Martin as the news was announced, the replacement of a CEO with a record of dwindling sales is always good news. Especially if he/she is replaced by someone better. Made around a 30% gain when I sold the stock today on a short term trade.
