Comcast Stock Surges: Here’s Why Traders Are Buzzing in August 2025

Comcast shares just got a rocket boost—and Wall Street's scrambling to keep up. Here's the breakdown.

Broadband Bets Pay Off (Again)

Another quarter, another case of cord-cutters driving straight into Comcast's broadband arms. The cable giant's internet division keeps printing money while legacy TV revenues crumble—classic pivot.

Peacock Finally Takes Flight

After burning cash like a meme-stock trader, their streaming service might actually be turning a corner. Ad-tier subscriptions smashed targets, proving even dinosaurs can adapt.

The Hidden Play Nobody's Talking About

Dark fiber deals and 5G backhaul contracts are padding margins while analysts nap on their spreadsheets. Typical.

So is this a sustainable rally or just another case of institutional FOMO? Either way—another reminder that boring infrastructure often outlives flashy disruptors. *Cough* crypto bros *cough*.

Comcast Q2 earnings

Sales inched only 2% higher year over year, and adjusted net income was up only 3% -- but earnings per share as calculated according to generally accepted accounting principles (GAAP) nearly tripled to an astounding $2.98, and free cash FLOW more than tripled to $4.5 billion.

That alone would more than explain investors' enthusiasm today.

Is Comcast stock a buy?

Comcast didn't give guidance for how the rest of the year will play out, and analysts who follow the stock might be in for a surprise. According to Yahoo! Finance data, earnings are only supposed to grow a penny (year over year) in Q3, and to decline in Q4 -- resulting in full-year 2025 profit declining $0.02 to $4.31 per share. Comcast's tremendous Q2, however, just delivered nearly three-quarters of the year's forecast profit in a single quarter, setting up Comcast to potentially thrash expectations by the end of this year.

Meanwhile, Comcast stock trades for a mere 5 times trailing earnings -- which might be the right price if earnings are shrinking, but could be incredibly cheap if earnings grow like it looks like they're going to. Even factoring Comcast's $100 billion-plus debt load into the picture, a stock that costs 5.3x earnings, pays a 4.1% dividend, and shows any growth at all would seem cheap to me.

Comcast stock is a buy.
