Following Executive...

Following corporate executives is not a good strategy. The executive might be good for one company but may not perform as well in other companies. You should invest in companies with good financial standing. But at the same time if a bad executive takes over then could be trouble. This is not the companies fault, but wrong executive decision.
Leadership is important and to keep everyone in synch to get the job done. Anyone can do this given the opportunity.
In the end, look for long term investment and company financial. What can they deliver. Company as one will deliver not just executive. Their job is to lead the vision of the company.
