Buying a call gives the right to buy 100 shares at the strike until expiry. Risk is capped at the premium paid; profit grows point-for-point above the breakeven (strike + premium).

Underlying (optional)
Market inputs

Premiums start as Black-Scholes model values — overwrite them with your broker’s real quotes for exact numbers.

Dollar P&L for the whole position. Pre-expiry cells are model values (constant IV); real marks will differ with volatility and skew.

Common questions

What is the maximum loss on a long call?
The premium paid. If the stock finishes at or below the strike at expiry, the call expires worthless and the loss equals the debit, no more.
What is the breakeven for a long call?
Strike price plus the premium paid per share. Above that at expiry, the position is profitable.
When do traders use long calls?
To express a bullish view with limited, defined risk — or to control upside exposure with less capital than 100 shares. Time decay works against the position.

Educational model, not trade advice. Options involve substantial risk and are not suitable for every investor — read the OCC’s Characteristics and Risks of Standardized Options. Model values use Black-Scholes with your inputs (constant volatility, European exercise, no dividends) and will differ from live market prices.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
