Assessing Millicom (NasdaqGS:TIGO): Is the Recent Rally Reflected in Its Current Valuation?

Kshitija Bhandaru
Millicom International Cellular (NasdaqGS:TIGO) has turned a few heads recently, as its stock price made a double-digit climb this month. Investors are understandably curious whether this renewed momentum hints at a real shift, from slow progress to possible growth in the months ahead. With TIGO’s longstanding presence in emerging telecom markets, even minor swings tend to spark fresh debates over its long-term potential. Glancing back over the year, TIGO’s stock has been anything but dull, boasting over 92% gain in the past twelve months and surging more than 28% in the past three months alone. While a dip over the past week may give some pause, the overall trend has moved upward, outpacing many sector peers. Still, mixed results on net income growth and revenue expansion offer plenty for valuation-focused investors to weigh as they look forward. So after such a steep rally, should buyers expect even more upside, or is the market already baking in Millicom’s future growth potential?
