Comcast (CMCSA)
Forward P/E is 6.27x against a peer median of 8.43x, a ratio of 0.74x — below the fair range — with trailing P/E 6.86x and PEG not available (shown as n/a). Latest-quarter revenue fell 6.1% year over year (PRIMARY, EDGAR), so the apparent discount fails the value-trap check: revenue is shrinking, and shrinking faster than the cluster, which is why the label is FAIRLY PRICED rather than UNDERVALUED. Delivered demand check: the Telecom & cable group's median growth was -1.2% year over year — demand falling, and this company is shrinking much faster than that pace.
What would change this label: Move to UNDERVALUED if revenue growth returns above 0% year over year for two quarters while the forward P/E stays below about 7.6x (0.90x the peer median). Move to OVERVALUED if the forward P/E rises above about 9.7x (1.15x the peer median) at unchanged estimates while revenue is still shrinking.
Comcast sells broadband internet, cable TV, media and entertainment. Its shares trade at about 6 times next year's expected earnings, below similar companies at about 8 times, but its sales fell about 6%. That shrinkage makes the shares fairly priced rather than a clear bargain.
Both lines start at 100 on 2020-09-01. Over the full window Comcast returned -48.36% and the S&P 500 +118.28% (price returns; dividends not reinvested). Worst peak-to-trough fall for Comcast: -64.4% (2021-09-02 to 2026-10-09). Source: Nasdaq official daily history.

Sales, profit and cash
This company does not report a gross-profit line in its SEC facts (normal for banks, payment networks and some health insurers), so profit is shown as net income instead — gross margin is marked UNVERIFIED-absent rather than estimated.
Free cash flow = cash from operations minus spending on plant and equipment, both from the company’s SEC cash-flow statement. Gaps are quarters where that spending line is not separately tagged in the filings — shown as gaps, never estimated.

The last twelve reported quarters. Full 25-quarter history sits in the data pack behind this page. A dash means the figure is not tagged as a standalone quarter in the company’s SEC facts (the usual case is the fourth quarter, which many companies only report inside the full-year filing) — it is missing, not zero.
Earnings: getting better or worse?
Each box is one quarter’s earnings per share (EPS). Green means EPS was higher than the same quarter a year earlier; red means lower; a dash means the figure is not tagged in the filings.
Basis: GAAP diluted EPS from SEC company facts, compared with the same quarter a year earlier.

What we could not verify
- Gross profit / gross margin: not tagged as a standalone line in this company's EDGAR company facts (common for banks, payment networks and some healthcare payers) — shown as UNVERIFIED-absent; the page charts revenue and net income instead.
- TTM GAAP diluted EPS could not be summed from company facts because at least one of the last four quarters (typically Q4) has no standalone tagged EPS; trailing P/E is therefore taken from the labelled secondary source in valuation_label.md.
- Own-history P/E range not yet compiled for this company in the Phase 1 batch run; the label rests on peer-median, growth and PEG evidence.
- PEG Ratio shown as n/a on statistics page
- Q3 2026 earnings release in CEO search results names Brian L. Roberts and Mike Cavanagh as co-CEOs; recorded Brian L. Roberts per profile page
- Guidance record (each quarter scored against the guidance the company gave the quarter before) is not yet compiled for this company — it is a Phase 2 layer. The earnings strip below therefore uses reported EPS versus a year earlier, which is fully sourced from filings.
The IT factor — the most exciting thing the market is overlooking — is not assessed on an X-Ray page. It belongs to the Deep Dive (Phase 2), where it gets the evidence standard it needs. Leadership-era scoring (the six years split by chief executive) is likewise a Phase 2 layer; this page names the current chief executive only, from a sourced profile.
