Long Call

Q: How much can I lose on a long call?

At most, the premium paid. If you buy a call for $300 and the underlying does not exceed the strike at expiration, you lose that $300 and not a cent more. That capped loss is why the long call is the usual entry point to options: the risk is known exactly before you open the position.

Q: Why does my call lose value when the stock rises?

For two reasons acting at once. Theta subtracts extrinsic value every day, so a slow rise may not offset the decay. And vega: if you bought with implied volatility inflated — typical ahead of earnings — and it then compresses, the option loses value even though price moved your way. That is IV crush.

Q: Which strike and expiration should I choose?

As a practical reference, a delta between 0.40 and 0.60 balances cost against probability, and 45 to 90 days to expiration avoids the zone where decay accelerates. Far out-of-the-money strikes are cheap but rarely end up worth anything, and deep in-the-money ones behave almost like the stock without providing useful leverage.

Q: Is it better to buy a call or buy the shares?

It depends what you want. The call offers leverage and capped loss, but it has an expiry date and pays theta every day. The stock does not expire, collects dividends and suffers no decay, but demands far more capital and its potential loss is much larger in absolute terms. The call makes sense when the thesis includes a deadline; the stock, when it does not.

Long Call at expiration

What is this strategy?

The Long Call is the most basic and direct strategy for capitalising on an upward move in the underlying asset. It simply involves buying a call option, granting the trader the right — not the obligation — to buy the asset at the specified strike price on or before the expiration date.

This strategy suits traders expecting the underlying price to rise significantly. Maximum gain is theoretically unlimited, since the asset price can rise indefinitely. The loss, however, is capped at the premium paid for the option, which makes it a defined-risk strategy.

The Long Call requires relatively little initial capital compared with buying the underlying outright, while still providing exposure to the price move. The breakeven point is calculated by adding the premium paid to the strike price.

Construction

Action	Instrument	Strike	Expiration	Example
BUY	1 Call	ATM or slightly OTM	30-60 DTE	+1 AAPL Jun 180 Call

Example

Scenario: Apple (AAPL) trades at $175. You expect it to rise over the next two months.

Option Purchased +1 AAPL Jun 180 Call @ $5.00
Total Cost $500 (5.00 × 100 multiplier)
Maximum Gain Unlimited (if AAPL rallies hard)
Maximum Loss $500 (premium paid)
Breakeven $185.00 (180 strike + 5 premium)
Profit at Expiration at $200 $1,500 (200−180−5) × 100

δDelta — Positive

Rises as price rises. An ATM call has a delta near 0.50, gaining about $50 if the underlying rises $1.

θTheta — Negative

Decreases with the passage of time. You lose value daily if the price stays flat.

νVega — Positive

Rises when implied volatility increases, which benefits the call buyer.

γGamma — Positive

Delta accelerates as price rises. Your bullish exposure grows as you move further into the money.

Position Management

01
Set a Stop Loss Consider losing 25–50% of the premium paid as the maximum. If you are down $250 on a $500 position, close it rather than riding it to zero.
02
Take Partial Profits Consider closing half the position once you are up 50–100% on the initial premium. That locks in gains and cuts remaining risk.
03
Monitor Volatility If volatility drops sharply, your option can lose value fast. Consider selling if conditions turn against the position.
04
Manage Near Expiration Under 7 days to expiration, theta accelerates. Close the position, or let it expire if it is in the money and you want assignment.
05
Roll the Position If price reaches the strike, sell this call and buy one at a higher strike further out to extend your bullish exposure.
