On Monday, auto parts supplier BorgWarner (NYSE: BWA) completed the spinoff of its fuel systems and aftermarket businesses into a new publicly traded company. The all-stock split is creating confusion on some websites that track stock prices, causing BorgWarner shares to appear down more than 10% in Wednesday trading. BorgWarner is an automotive industry specialist that traces its roots back to 1928, but the company is a standout for investors these days due to its focus on the future.
