Fortis shares rise 8.87% premarket driven by Zacks B Momentum Score, upward earnings revisions, and defensive momentum in volatile market.

Fortis surged 8.87% in premarket trading, driven by renewed investor confidence in its momentum profile and earnings trajectory. The stock’s Zacks Momentum Style Score of B, coupled with upward revisions to its full-year earnings estimates, positioned it as a top momentum pick amid market volatility. Recent price gains—4.92% over the past quarter and 24.23% annually—outperformed the S&P 500, while the utility sector’s negative performance highlighted Fortis’s relative strength. Analysts cited the stock’s resilience, stable dividend yields, and improving earnings outlook as key catalysts. The upcoming February 12 earnings report is expected to validate the sustainability of this momentum, though structural risks related to regulated utility operations and cash flow pressures remain.
