CMCSA Short Squeeze Score: -
CMCSA ranked on Tapeboard's 0-100 short squeeze leaderboard · components disclosed below · methodology fully published
This score isn't static — short interest re-settles every two weeks and CMCSA's borrow fee can spike intraday. Tapeboard re-scores CMCSA every day, ranks it against the full live squeeze board, and pairs it with a real-time scanner and watchlist — so you catch the setup changing, not a snapshot. Free, no card.
How CMCSA got to -
Since setup v5 (2026-09-28), a stock is ranked only if its short interest is at least 15% of float. Ranked names are scored 0-100 on 20-day volatility (70%) and 5-day float rotation (30%), each as a percentile among the gated names. A higher score means higher historical odds of a large move in either direction; it is not a directional call. The inputs below (short interest, borrow fee, float utilization, days to cover, momentum, short-volume ratio, fee change) are shown for context at zero weight.
Not on today's ranked board. The squeeze board covers stocks with short interest of at least 15% of float and is rebuilt after each session's close.
CMCSA 30-day borrow fee and short interest trend
Trailing-30-day series of two of the highest-signal squeeze inputs for CMCSA, the IBKR borrow fee (cost to short the stock) and short interest as a percentage of float. Free per-ticker borrow-fee history is not published by Fintel or Ortex on their public pages.
Insufficient history, CMCSA has fewer than 5 days of squeeze-score data on file. Sparkline returns once the daily ingest accumulates a full 30-day window (typically 2-3 weeks for newly-listed or newly-shorted tickers).
How the score is calculated
Tapeboard's short squeeze score (setup v5) gates on short interest of at least 15% of float (FINRA settlement, point-in-time and split-safe), then ranks by 70% 20-day volatility percentile + 30% 5-day float-rotation percentile. Out of sample, the top 10 moved +20% within five sessions about 17% of the time and fell 20% about 12% of the time, against 4.5% and 2.3% for all stocks. Sources: FINRA consolidated short-interest files for short interest, daily bars for volatility and rotation, IBKR Stock Loan Availability for borrow fees (context), and FINRA CNMS daily short sale volume files for the heavy-short-volume flag (context; not the Reg SHO threshold list). The full methodology, including the calibrated odds table and known limitations, is published at /methodology/short-squeeze-score.

Frequently asked questions about CMCSA squeeze risk
What does a Short Squeeze Score of - mean for CMCSA?
A score of not available for CMCSA means it is either low on the setup board (quieter than other heavily shorted names) or not ranked at all (short interest below 15% of float, or incomplete data). Low-ranked gated names historically reached +20% within five sessions about 5% of the time, close to the 4.5% base rate for all stocks.
How fresh is the CMCSA squeeze data?
CMCSA's score recomputes once daily after the US market close (typically by 9 PM ET). Volatility and float rotation come from daily price bars; borrow fee and the other context fields refresh daily. Short interest carries the most recent FINRA settlement date and is held between readings, because FINRA publishes short interest on a settlement schedule, not daily. That is why the SI %Float row above is stamped with its own as-of date. Real-time short interest does not exist publicly in US markets.
Is CMCSA on the FINRA threshold list?
As of the most recent FINRA file, CMCSA is not on the threshold list. The list is published end-of-day and a ticker can move on or off based on cumulative settlement failures over rolling five-day windows. See stocks currently on the threshold list.
