What’s Next For Merck Stock After A 5% Fall In A Week?

The stock price of Merck (NYSE: MRK) reached its all-time high of around $82 in Sep 2020. It has since hovered in the range of $70-80 for the better part of the last year, before a recent sell-off in pharmaceutical stocks resulted in MRK falling to $72 levels currently. MRK stock is down over 5% in the last five trading days. Even before the recent fall, MRK stock underperformed its peers, due to rising concerns of slowing sales for some of its drugs, such as, Januvia and Janumet, along with the impact of the Covid-19 pandemic on its vaccines, including Gardasil. However, the recent decline can be attributed to rising concerns over the Biden’s administration’s plan to reduce healthcare costs, including negotiating the drug prices in its Medicare program. But will MRK stock continue its downward trajectory over the coming weeks, or is a recovery in the stock imminent?

According to the Trefis Machine Learning Engine, which identifies trends in the company’s stock price using ten years of historical data, returns for MRK stock average around 4.1% in the next one-month (twenty-one trading days) period after experiencing a 5.1% drop over the previous week (five trading days), implying that the stock will likely rebound in the near term.
