How are CMCSA long put max profit and max loss calculated?

Max profit equals the strike minus premium times 100 (reached at zero); max loss equals the premium times 100. Breakeven is strike minus premium. For the CMCSA long put priced from the end-of-day chain at a 30-day expiry (ATM IV 43.19%), the computed maximum profit is $2,288.50 per contract and the computed maximum loss is -$110.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CMCSA long put?

The breakeven for the CMCSA long put priced on this page is roughly $22.90 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current CMCSA market-implied 1-standard-deviation expected move is approximately 12.38%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current CMCSA implied volatility affect this long put?

CMCSA ATM IV is at 43.19% with IV rank near 71.29%, which is elevated relative to its 1-year range. Premium-selling structures (covered call, cash-secured put, iron condor) generally look more attractive when IV rank is high; premium-buying structures (long call, long put, debit spreads) are more expensive in that regime.

CMCSA Long Put Strategy

CMCSA (Comcast Corporation), in the Communication Services sector, (Telecommunications Services industry), listed on NASDAQ.

Comcast Corporation functions as a global media and technology conglomerate. Its diverse operations are segmented across Cable Communications, Media, Studios, Theme Parks, and Sky. The Cable Communications division delivers internet, television, phone, and mobile services to residential and business clients under its Xfinity brand, alongside offering advertising solutions. Its Media segment encompasses NBCUniversal's television and streaming platforms, including its national, regional, and international cable channels, the NBC and Telemundo broadcast networks, and the Peacock streaming service. The Studios segment is responsible for NBCUniversal's film and television production and distribution activities. Through its Theme Parks division, Comcast manages Universal Studios resorts located in Orlando, Florida; Hollywood, California; Osaka, Japan; and Beijing, China.

CMCSA (Comcast Corporation) trades in the Communication Services sector, specifically Telecommunications Services, with a market capitalization of approximately $82.77B, a trailing P/E of 4.46, a beta of 0.66 versus the broader market, a 52-week range of 22.13-34.35801, average daily share volume of 31.9M, a public-listing history dating back to 1980, approximately 182K full-time employees. These structural characteristics shape how CMCSA stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.66 indicates CMCSA has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 4.46 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. CMCSA pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a long put on CMCSA?

A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.

Current CMCSA snapshot

As of June 30, 2026, spot at $24.39, ATM IV 43.19%, IV rank 71.29%, expected move 12.38%. The long put on CMCSA below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 31-day expiry.

Why this long put structure on CMCSA specifically: CMCSA IV at 43.19% is rich versus its 1-year range, which makes a premium-buying CMCSA long put relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 12.38% (roughly $3.02 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CMCSA expiries trade a higher absolute premium for lower per-day decay. Position sizing on CMCSA should anchor to the underlying notional of $24.39 per share and to the trader's directional view on CMCSA stock.

CMCSA long put setup

The CMCSA long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CMCSA near $24.39, the first option leg uses a $24.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CMCSA chain at a 31-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 CMCSA shares for the stock leg in covered calls and collars).

CMCSA thesis for this long put

The market-implied 1-standard-deviation range for CMCSA extends from approximately $21.37 on the downside to $27.41 on the upside. A CMCSA long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CMCSA position with one put per 100 shares held. Current CMCSA IV rank near 71.29% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on CMCSA at 43.19%. As a Communication Services name, CMCSA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CMCSA-specific events.

CMCSA long put positions are structurally bearish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. CMCSA positions also carry Communication Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CMCSA alongside the broader basket even when CMCSA-specific fundamentals are unchanged. Long-premium structures like a long put on CMCSA are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current CMCSA chain quotes before placing a trade.
