## Direct answer

An option contract connects a buyer, or **holder**, with a seller, or **writer**:

- A **Call** gives its holder the right to buy the underlying at the strike under the contract terms.
- A **Put** gives its holder the right to sell the underlying at the strike.
- The holder pays premium and chooses whether to exercise.
- The writer receives premium and must perform if assigned.

“Call is bullish and Put is bearish” is incomplete. Position direction matters: buying and selling the same option create opposite payoff and obligation profiles.

| Position | Initial cash flow | General exposure | Expiration maximum loss |
| --- | --- | --- | --- |
| Long Call | Pay premium | Bullish | Premium plus costs |
| Short Call | Receive premium | Bearish/neutral | Theoretically unlimited if uncovered |
| Long Put | Pay premium | Bearish/protective | Premium plus costs |
| Short Put | Receive premium | Bullish/neutral | Substantial, as stock can fall to zero |

## Rights, obligations, and payoff formulas

Let `S` be the underlying price at expiration, `K` the strike, and `P` the premium per underlying unit.

`Long Call profit = max(S - K, 0) - P`

`Short Call profit = P - max(S - K, 0)`

`Long Put profit = max(K - S, 0) - P`

`Short Put profit = P - max(K - S, 0)`

Long and short results are opposite before fees when their terms and entry premium match. The expiration break-even is `K + Call premium` for a Call buyer and writer, and `K - Put premium` for a Put buyer and writer. Break-even describes expiration, not the option's market value before expiration.

### Four contracts, four economic positions

- **Long Call:** right to buy; no obligation to exercise; unlimited theoretical upside and premium-limited loss.
- **Short Call:** obligation to sell or settle if assigned; premium-limited profit; an uncovered position can lose without a theoretical ceiling.
- **Long Put:** right to sell; useful for a bearish view or protecting owned assets; finite profit because the underlying cannot ordinarily fall below zero.
- **Short Put:** obligation to buy or settle if assigned; premium-limited profit; loss can approach `K - premium` per share if the underlying becomes worthless.

A covered Call, cash-secured Put, protective Put, spread, or other combination changes portfolio economics. “Covered” and “cash-secured” describe collateral or accompanying holdings; they do not remove market loss.

### Contract terms still control

Verify underlying, Call or Put, long or short side, strike, expiration, multiplier, deliverable, exercise style, settlement, and quantity. Standard equity options commonly use a 100-share multiplier, but adjusted and index contracts can differ. American-style shorts can be assigned before expiration; European-style contracts generally cannot be exercised until expiration.

Before expiration, price also depends on remaining time, implied volatility, rates, expected dividends, and liquidity. A correct direction can lose when the move is too small or late, IV changes adversely, or spreads are wide.

## One strike, all four positions

Assume standard 100-share contracts with strike `$100`. The Call premium is `$4` (`$400` per contract) and the Put premium is `$3` (`$300` per contract). Results below are at expiration, before fees.

| Stock at expiration | Long Call | Short Call | Long Put | Short Put |
| --- | ---: | ---: | ---: | ---: |
| `$80` | `-$400` | `+$400` | `+$1,700` | `-$1,700` |
| `$100` | `-$400` | `+$400` | `-$300` | `+$300` |
| `$120` | `+$1,600` | `-$1,600` | `-$300` | `+$300` |

At `$120`, Call intrinsic value is `$20 × 100 = $2,000`; subtracting the `$400` premium gives the long Call `$1,600`, while the short Call loses `$1,600`. At `$80`, Put intrinsic value is also `$2,000`; subtracting `$300` gives the long Put `$1,700`, opposite the short Put.

Call expiration break-even is `$100 + $4 = $104`. Put expiration break-even is `$100 - $3 = $97`. At `$100`, both options expire with no intrinsic value, so buyers lose and writers retain the premiums before costs.

## From order to expiration

- `Buy to Open` creates a long option; `Sell to Close` exits it.
- `Sell to Open` creates a short option; `Buy to Close` exits it.
- A holder can normally sell instead of exercising, subject to liquidity.
- Exercise can create a stock purchase, stock sale, or cash settlement.
- Assignment imposes the corresponding obligation on a writer selected through clearing and broker procedures.
- An in-the-money option near expiration can be automatically exercised under applicable procedures, but broker rules and contrary instructions matter.
- After-hours movement, pin risk, dividends, and broker cutoffs can make expiration outcomes differ from a simple payoff chart.

For each position, calculate premium cash flow, multiplier, expiration break-even, maximum gain and loss, stock or cash created by exercise/assignment, margin or funding needs, and an exit deadline.

## Risks and boundaries

- **Buyer premium loss:** a long option can lose 100% of premium.
- **Writer obligation:** premium received is small relative to possible assignment exposure.
- **Uncovered Call risk:** loss can grow as the underlying rises.
- **Short Put downside:** assignment can require buying a collapsing asset at the strike.
- **Time decay:** generally harms buyers and helps writers only if other variables do not overwhelm it.
- **Volatility repricing:** IV changes can offset correct directional movement.
- **Leverage:** option percentage changes can be much larger than the underlying's.
- **Liquidity:** Mid or model value may not be executable.
- **Exercise and assignment:** unexpected stock, cash, margin, dividend, or borrow consequences can arise.
- **Adjusted contracts:** corporate actions may change the standard multiplier or deliverable.
- **Combination risk:** one safe-looking leg cannot describe the risk of the whole portfolio.

## Common misconceptions

- “A Call is bullish.” A long Call is bullish; a short Call has the opposite exposure.
- “A Put is bearish.” A long Put is bearish or protective; a short Put is generally bullish/neutral.
- “Buyers can be assigned.” Assignment applies to writers; holders decide on exercise, subject to procedures.
- “Writers receive free income.” Premium compensates an enforceable obligation.
- “Limited loss means a long option is low risk.” A frequent 100% premium loss can be material.
- “Short Put risk is unlimited.” It is very large but bounded by the underlying reaching zero.
- “Covered means no loss.” The accompanying stock can fall substantially.
- “In the money means profitable.” Premium and costs determine profit.
- “Exercise is required to realize value.” An offsetting closing trade is usually available when liquid.
- “Every contract represents 100 shares.” Adjusted and non-equity contracts can differ.
