As the closing bell rang Friday, stocks rallied for a strong finish to the week. Here's what TheStreet learned in a hectic week riddled with deals, breaking news and major market moves. 

First, always have your team's back. We're looking at you, Gap Inc. (GPS) . In the company's announcement that President Jeff Kirwan is leaving, CEO Art Peck said Gap has "not achieved operational excellence and accelerated profit growth." Way to throw him under the bus. 

Second, know your team. This one's for Ford Motor Co. (F) , which this week announced executive VP and North America president Raj Nair is leaving the company following an investigation into reports of inappropriate behavior. 

Lastly, take a breath and enjoy the weekend. Remember that one of the best investing moves you can make is to simply stay the course. If it works for Warren Buffett, it will work for you.
