Philip Morris

Philip Morris stock (NYSE: PM) has rallied 34% in the last six months (126 trading days) and is currently trading at $95 per share. Despite belonging to a defensive sector (tobacco), the stock has been able to register healthy gains in the last few months with the company beating analysts’ expectations in Q1 2021 and providing an upbeat forecast for the coming quarters. Heated tobacco shipments increased by 30% y-o-y in Q1 2021, while the market share of heated tobacco units in markets where IQOS is sold was up 1.7% to reach 7.6%. With the vaping market expected to grow at a healthy double-digit rate in the coming years, Philip Morris is expected to benefit with higher IQOS sales. Also, though the steps contemplated by the U.S. government to make tobacco products less attractive (by reducing nicotine content in cigarettes) has taken a heavy toll on Altria’s stock, Philip Morris saw an increase as it does not operate in the U.S. market.  But will PM’s stock continue its upward trajectory over the coming weeks, or is a correction in the stock more likely?

According to the Trefis Machine Learning Engine, which identifies trends in a company’s stock price data for the last ten years, returns for PM stock average close to -0.6% in the next one-month (21 trading days) period after experiencing a 34% rise over the previous six-month (126 trading days) period. Notably, though, the stock is likely to perform at par with the S&P500 over the next month, with an expected return which would be in line with the S&P500.
