These stocks climbed in Friday's holiday finish to the week. Find out why.

Friday was largely a day of rest for the stock market, with major market benchmarks mixed as investors continue to grapple with all the implications of the presidential election and its future impact. The Dow finished up 40 points on the day, but the S&P 500 fell slightly, and the oil and gold markets posted substantial declines. Yet amid the mixed performance from broad indexes, some stocks enjoyed big gains, and PTC Therapeutics (PTCT -1.40%), Advanced Micro Devices (AMD -2.12%), and Nordstrom (JWN 0.97%) were among the best-performing stocks in the market. Below, we'll look more closely at these stocks to tell you why they did so well.

PTC Therapeutics wins an unexpected victory

PTC Therapeutics launched 88% higher after the Committee for Medicinal Products for Human Use of the European Medicines Agency recommended the renewal of the marketing authorization for the company's Translarna Duchenne muscular dystrophy treatment. Many investors had feared that the committee's conditional approval might not be renewed, but the regulatory decision paves the way for renewed approval from the European Commission, which is likely to follow the committee's recommendation. For PTC, the decision requires it to do a new 18-month study of the drug in connection with the disease, with results expected for early 2021. Still, even with today's gains, the stock trades at only about a third of where it started the year.

AMD rides the coattails of its competitor

Advanced Micro Devices climbed by 6% in the wake of positive results from its primary competitor in the graphics processing chip market. NVIDIA soared by nearly 30% after posting exceptionally strong quarterly financials, which many saw as transformative for that company. For Advanced Micro, investors apparently took the news from its competitor as positive for the entire industry, despite the fact that others believe that AMD might well suffer because of its rival's success. Going forward, AMD will have to demonstrate its ability to retain control of its niches within the market and successfully defend them, or else the upward movement of both stocks in concert might well turn to disparate performance.

Nordstrom signals retail strength

Finally, Nordstrom finished higher by 5%. The high-end department store retailer reported its third-quarter financial numbers Thursday afternoon, and investors were pleased with a return to solid comparable-store sales gains and good earnings performance. Aggressive expansion in store counts was centered on the discount Nordstrom Rack concept, but the retailer also said that its earnings for the full year would be higher than it had previously expected. The struggles for retailers aren't entirely over and done with, but Nordstrom's results suggested that the company might at least have some positive momentum moving into the key holiday season.
