Millicom’s Q4 2025 earnings release ignited a sharp intraday rally, propelling the stock to a 52-week high. The surge reflects robust organic revenue growth, strategic acquisitions, and a deleveraged balance sheet. With the stock trading near its all-time peak, traders are now weighing whether this is a sustainable breakout or a cautionary overbought setup.

Q4 Earnings Power Drives TIGO's Intraday Rally
Millicom’s Q4 2025 results delivered a triple threat: 4.7% organic revenue growth to $1.7B, a record $778M Adjusted EBITDA, and $278M in equity free cash flow. CEO Marcelo Benitez highlighted disciplined cost control, postpaid migration, and fixed-mobile convergence as key drivers. The $975M Lati tower sale and acquisitions in Colombia, Chile, and Coltel further strengthened the balance sheet, reducing leverage to 2.31x. These milestones, coupled with a $916M FY 2025 EFCF beat, positioned TIGO as a high-conviction growth story, triggering a breakout above its 52-week high.

Telecom Sector Mixed as TIGO Outpaces Peers
The iShares U.S. Telecommunications ETF (IYZ) fell 1.09%, while Verizon (VZ) edged up 0.15%. TIGO’s 3.76% surge outperformed sector peers, reflecting its unique focus on Latin American expansion and infrastructure monetization. The sector’s underperformance highlights TIGO’s differentiation through strategic divestitures and postpaid growth, contrasting with legacy carriers’ regulatory and margin pressures.

Backtest Millicom Stock Performance
The backtest of TIGO's performance following a 4% intraday increase from 2022 to the present shows impressive results. The strategy achieved a 129.79% return, significantly outperforming the benchmark, which returned 42.26%. The excess return was 87.53%, indicating that the strategy's focus on intraday percentage changes greater than 4% was highly beneficial.However, it's important to note that the strategy had a maximum drawdown of 64.92%, which is relatively high, and a volatility of 39.52%. This suggests that while the strategy delivered strong returns, it also came with considerable risk and fluctuations. The Sharpe ratio of 0.57 indicates that the risk-adjusted returns were acceptable but not exceptional.In conclusion, the strategy's ability to capitalize on intraday surges led to substantial gains, but it was not without its risks. Investors should carefully consider their risk tolerance and the potential for significant losses when employing such a strategy.

TIGO at a Pivotal Crossroads: Ride the Momentum or Hedge the Overbought Risk
Millicom’s Q4 earnings have created a high-conviction trade, but the stock’s proximity to its 52-week high and RSI near 60 suggest caution. The $69.55 Bollinger upper band and 200D MA at $47.79 indicate a strong bullish bias, yet overbought conditions could trigger a pullback. Traders should monitor the $67.455 intraday low as support and the $72.18 52-week high as resistance. With Verizon (VZ) up 0.15%, the telecom sector’s mixed performance underscores TIGO’s standalone momentum. Now: Buy TIGO20260320C65 for a 5% upside target or short TIGO20260320P65 if $65.00 breaks. Watch for a $70.00 close to confirm the breakout.
