-It would have been nice to take the summer off, but there was still money to be made in the markets if you didn’t “sell in May and go away.”

While politics and tragedy dominated the headlines the past three months, global financial markets maintained their steady march higher. The S&P 500 Index rose roughly 2 percent and volatility was remarkably subdued outside of a few spikes. However, some stocks did experience price moves of over 50 percent since May, leaving investors with outsize returns if they played their cards right.

Here are a few of the more notable moves this summer -— though not all of them were positive for investors.

NRG Energy Inc. 

The U.S. power generator’s shares took off after it came under pressure from billionaire investor Paul Singer to streamline. The firm is the biggest winner in the S&P 500, surging 54 percent.
