With people staying inside and self-isolating to stem the spread of the novel coronavirus, many video games saw increased player engagement -- and many gaming stocks proved relatively resilient in last month's tumultuous trading. Zynga may also have benefited from the new video game it announced at the beginning of the month, set in J.K. Rowling's Wizarding World franchise. Image source: Getty Images. So what Zynga published a press release on March 5 announcing its upcoming game, Harry Potter: Puzzles & Spells. The game will be set in the match-three puzzle genre, and be available on Android, Apple iOS, Facebook, and Amazon Kindle platforms. While the announcement of Harry Potter: Puzzles & Spells may have helped Zynga's stock last month, heightened player activity and general resilience for video game stocks were probably bigger factors in the company's performance. Verizon CEO Hans Vestberg stated that his company's network had seen a 75% increase in gaming traffic since the start of the novel coronavirus outbreak, and investors seem to have liked Zynga's odds of soaking up extra player engagement. Now what Zynga stock has slipped early in April's trading, despite positive momentum for the broader market. The video game company's share price is down roughly 5% in the month so far: ^SPX data by YCharts. Zynga's first-quarter earnings period closed at the end of March, and the company will likely report its first-quarter earnings results some time next month. While some companies have either cut or fallen short of guidance due to the novel coronavirus, the digital nature of Zynga's business suggests that it stands a good chance of hitting its sales target.
