Comcast Stock Jumps 20% In 3 Months – Will The Rally Continue?

CMCSA: Comcast logo

Comcast stock (NASDAQ: CMCSA) increased almost 20% in the last three months and is currently trading at close to $50 per share. The company’s foray into streaming with the launch of Peacock in mid-2020 also helped boost the stock price as streaming demand has been high during the pandemic. The company beat analysts’ expectations in the recently released FY2020 results, which provided a further boost to the stock price. The Peacock video-streaming reported 33 million total sign-ups. Financials in 2021 are expected to improve as gradual lifting of lockdowns will drive some recovery in the most affected segments of Comcast, like movie theaters and theme parks. The management also increased the dividend by 9% in January 2021. But will Comcast’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 20 years, returns for CMCSA stock average close to 3% in the next three-month (63 trading days) period after experiencing a 20% rise over the previous three-month (63 trading days) period. Notably, though, the stock is likely to outperform the S&P500 over the next month, with an expected return which would be 2.5% higher compared to the S&P500.

Some Fun Scenarios, FAQs & Making Sense of CMCSA Stock Movements:

Question 1: Is the average return for Comcast stock higher after a drop?


Consider two situations,

Case 1: Comcast stock drops by -5% or more in a week

Case 2: Comcast stock rises by 5% or more in a week

Is the average return for Comcast stock higher over the subsequent month after Case 1 or Case 2?

CMCSA stock fares better after Case 1, with an average return of 1.4% over the next month (21 trading days) under Case 1 (where the stock has just suffered a 5% loss over the previous week), versus, an average return of 0.8% for Case 2.

In comparison, the S&P 500 has an average return of 3.1% over the next 21 trading days under Case 1, and an average return of just 0.5% for Case 2 as detailed in our dashboard that details the average return for the S&P 500 after a fall or rise.
