Questions about CMCSA
What people ask.
Why is CMCSA on Broken Stocks?
CMCSA qualifies for the Red List on decline depth. It is down -23.7% from its rolling 252-day high of $32.98, set on 2025-07-03 — 329d ago.
Is CMCSA a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. CMCSA is down -23.7% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.
Is CMCSA a buy?
Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.
Where is CMCSA trading inside its 52-week range?
At $25.16, CMCSA sits 10.0% of the way from its 52-week low ($24.13) to its 52-week high ($34.36). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CMCSA been declining?
The current 23.7% decline accrued over 329d, which annualizes to roughly -26.3% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.
How does CMCSA compare to its sector?
There are 41 other Communication Services tickers on Broken Stocks: 28 Red, 6 Amber, 7 Watch, with 17 showing recovering structural signals. Median sector decline is -45.9% — CMCSA's decline is shallower than the sector median.
Does CMCSA's earnings date affect its tier?
No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-04-23) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
