T-Mobile U.S. stock (NASDAQ: TMUS) has increased 13% in the last three months and currently trades at $149. The rally in the stock was driven due to strong Q1 2021 performance. The company reported revenues of $19.8 billion in Q1 2021. TMUS added 260,000 net new postpaid accounts and 773,000 postpaid lines during the quarter. The new account adds were twice as much as the previous quarter. T-Mobile’s customer base now stands at more than 103 million, which puts it ahead of AT&T and makes it the second largest telecom player, just behind Verizon. The deal with Sprint is helping T-Mobile register healthy subscriber growth, while also providing the company access to Sprint’s key radio frequency assets which, when combined with T-Mobile’s, will give it industry-leading 5G technology. T-Mobile’s 5G network already covers 1.6 million square miles of the U.S., more than double its next closest competitor, AT&T. T-Mobile plans to extend that network to smaller markets and rural areas, thus aiming to raise that share close to 20% in the next five years, from its level of share which is in the low teens currently.  But will TMUS’ stock continue its upward trajectory over the coming weeks, or is a correction in the stock more likely?

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

Question 1: Is the average return for T-Mobile US stock higher after a drop?


Consider two situations,

Case 1: T-Mobile US stock drops by -5% or more in a week

Case 2: T-Mobile US stock rises by 5% or more in a week

Is the average return for T-Mobile US stock higher over the subsequent month after Case 1 or Case 2?

TMUS stock fares better after Case 1, with an average return of 5.4% 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 1.8% for Case 2.
