Every option is either a call or a put. A call option gives its buyer the right to buy the underlying asset at the strike price. A put option gives its buyer the right to sell the underlying at the strike price. Calls gain value when the underlying rises; puts gain value when it falls. Everything else in options, from income strategies to complex spreads, is built from combinations of calls and puts, bought or sold.

## Calls at a glance

A call is a bet that the price will rise above the strike, or a way to lock in a purchase price.

| | Call buyer | Call seller |
|---|---|---|
| View | Bullish | Neutral to bearish |
| Pays or receives | Pays premium | Receives premium |
| Profit when | Price rises above strike plus premium | Price stays below strike |
| Maximum loss | Premium | No upper limit (uncovered) |
| Maximum gain | No upper limit | Premium |

*Figure: A long call at expiration: the most you can lose is the premium.*

## Puts at a glance

A put is a bet that the price will fall below the strike, or insurance against a decline.

| | Put buyer | Put seller |
|---|---|---|
| View | Bearish, or hedging | Neutral to bullish |
| Pays or receives | Pays premium | Receives premium |
| Profit when | Price falls below strike minus premium | Price stays above strike |
| Maximum loss | Premium | Strike minus premium (if price goes to zero) |
| Maximum gain | Strike minus premium | Premium |

*Figure: A long put at expiration: profit grows as price falls, down to zero.*

## Worked examples

**Example: A call and a put on the same stock**
A stock trades at $100. A $105 call costs $3 and a $95 put costs $2.50. Each contract covers 100 shares.

- **Stock rises to $115 at expiry:** the call is worth $10 ($115 minus $105). Profit = ($10 minus $3) × 100 = $700. The put expires worthless: loss $250.
- **Stock falls to $85:** the put is worth $10 ($95 minus $85). Profit = ($10 minus $2.50) × 100 = $750. The call expires worthless: loss $300.
- **Stock ends at $100:** both expire worthless. The call buyer loses $300; the put buyer loses $250.

## Break even points

```
call break even = strike + premium
put break even = strike - premium
```

The $105 call bought for $3 breaks even at $108 at expiration; the $95 put bought for $2.50 breaks even at $92.50.

## Four basic positions

Combining buying and selling with calls and puts gives four building blocks:

| Position | View | Lesson |
|---|---|---|
| Long call | Bullish | [Long Call](https://learn.tradelabsai.com/options/long-call/) |
| Short call | Bearish or neutral | [Short Call](https://learn.tradelabsai.com/options/short-call/) |
| Long put | Bearish | [Long Put](https://learn.tradelabsai.com/options/long-put/) |
| Short put | Bullish or neutral | [Short Put](https://learn.tradelabsai.com/options/short-put/) |

Every multi leg strategy, such as spreads, straddles and condors, combines these four. See [Vertical Spreads](https://learn.tradelabsai.com/options/vertical-spreads/) and [Straddle](https://learn.tradelabsai.com/options/straddle/).

## Calls, puts and the underlying

Calls and puts are linked to the underlying and to each other through [Put-Call Parity](https://learn.tradelabsai.com/options/put-call-parity/): a long call plus a short put at the same strike and expiry behaves like owning the underlying. This relationship explains why traders can build "synthetic" positions. See [Synthetic Positions](https://learn.tradelabsai.com/options/synthetic-positions/).

## A memory aid

- **Call up:** you "call" the asset to you, so you want the price to rise.
- **Put down:** you "put" the asset onto someone else, so you want the price to fall.

## Common mistakes

- **Confusing buying a put with selling a call.** Both are bearish, but the risks are very different.
- **Ignoring the premium** when calculating break even.
- **Forgetting the 100 share multiplier** on US stock options.

## Frequently asked questions

### What is the difference between a call and a put?

A call gives the right to buy at the strike price and gains when prices rise; a put gives the right to sell at the strike price and gains when prices fall.

### Is buying a put the same as short selling?

Both profit from a fall, but a put buyer's loss is limited to the premium, while a short seller has no upper limit on losses if the price rises.

### Can you sell a call without owning the stock?

Yes, that is an uncovered or naked call. It carries risk with no upper limit and requires a high level of broker approval.
