Can you buy calls and puts on the same stock?

Short answer: yes — you can buy calls and puts on the same stock. In U.S. equity markets and in crypto derivatives venues, traders often buy a call and a put that reference the same underlying asset to trade or hedge volatility. Popular approaches include the long straddle (same strike, same expiration) and the long strangle (different strikes, same expiration). Availability, settlement and execution details depend on whether the underlying is a listed equity, an index, or a crypto token and on the broker or exchange used.

Basic definitions and mechanics

A call option gives the buyer the right, but not the obligation, to buy the underlying asset at a predetermined price (the strike) before or at a set expiration. A put option gives the buyer the right, but not the obligation, to sell the underlying asset at the strike by expiration. Buyers pay a premium to the seller for these rights. When you buy a call and buy a put on the same stock, you hold two separate contracts that reference the same underlying security.

In U.S. equity options, one standard contract typically represents 100 shares of the underlying stock. That contract multiplier affects required capital and risk. The buyer’s maximum loss for each option is the premium paid. When buying both sides — call and put — the combined maximum loss equals the sum of the two premiums paid.

Key mechanical details to remember:

Strike: the price at which each option can be exercised.
Expiration: the date the option rights lapse.
Premium: the upfront cost to buy an option.
Contract size / multiplier: commonly 100 shares for listed equity options.
Exercise style: American-style equity options can be exercised any time before expiration; some index or crypto options are European-style.

Common strategies that involve buying both a call and a put

Long straddle

A long straddle is formed by buying a call and buying a put with the same strike and the same expiration. It is typically structured at-the-money (ATM) so both options have similar deltas. The primary objective is to profit from a large price movement in either direction — up or down. The strategy benefits from increased realized volatility or a rise in implied volatility after entry.

Cost considerations: because both options are ATM, premiums are higher than OTM alternatives. Time decay (theta) erodes option value daily, so the underlying must move sufficiently, and preferably quickly, to offset time decay and breakeven costs.

Long strangle

A long strangle buys an out-of-the-money (OTM) put and an OTM call with the same expiration but different strikes. This reduces premium outlay relative to a straddle, since OTM options are cheaper. The trade requires a wider move to reach breakeven, but the maximum loss (total premiums) is smaller. Traders use strangles when they expect a sizable move but want lower upfront cost than an ATM straddle.

Other relevant multi-leg positions

Buying both options can be combined with other positions to create hybrids:

Buy call + buy put + hold stock (protective combinations) — alters downside protection and upside exposure.
Buy both options and sell other options to form spreads that reduce cost but add complexity and different payoff shapes.
Short straddle / short strangle — selling both options is the opposite trade, collecting premiums but exposing the seller to potentially large losses; this is not the same as buying both sides.

Why traders buy both (use cases)

Traders and hedgers buy both a call and a put on the same stock for several reasons:

Volatility speculation: profit if the underlying moves a lot, regardless of direction.
Event hedging: protect or trade around scheduled events such as earnings, regulatory rulings, product launches, or macro announcements.
Portfolio protection: limit downside risk around a concentrated holding while preserving upside exposure (structured depending on strikes and sizes).
Tactical speculation: when implied volatility is low but a large move is expected, buyers may take long straddles or strangles to capitalize on an anticipated volatility rise.

Payoff profiles and risk/reward

When you buy both a call and a put, payoff profiles depend on strikes and premiums paid. For standard long straddles and strangles:

Maximum loss = total premiums paid (occurs if options expire worthless).
Breakeven points for a long straddle with strike K and premiums C (call) and P (put): upside breakeven = K + (C + P); downside breakeven = K - (C + P).
Strangle breakevens depend on both strikes: upside breakeven = call strike + total premiums; downside breakeven = put strike - total premiums.
Upside profit for the call is unlimited as price rises; downside for the put is limited (stock price cannot go below zero) but can be large in percentage terms.
Time decay (theta) works against long option buyers — the position loses value over time if the underlying remains relatively stable.

Contrast this with selling both options: sellers collect premiums but expose themselves to potentially unlimited upside risk (for uncovered calls) or substantial downside risk. Buying both options is a defined-loss, unlimited-upside (on the call side) strategy subject to breakeven thresholds.

Selecting strikes and expirations

Choosing strikes and expirations determines cost, sensitivity to price moves, and time decay exposure.

ATM strikes: higher premiums, higher initial sensitivity (gamma) to price moves; commonly used for straddles.
OTM strikes: lower premiums, require larger moves to profit; commonly used for strangles.
Expiration length: short-dated options have faster theta decay but are cheaper; long-dated options cost more but suffer slower time decay.
Event-timing: pick expirations that include the event you want to trade or hedge; be mindful of implied volatility spikes before events and potential volatility crush after the event.

Pricing drivers and the Greeks

Option prices are driven by several core factors summarized by the Greeks:

Delta: sensitivity of option price to changes in the underlying. Long straddles typically have near-zero net delta initially (one positive delta from the call and one negative delta from the put), but gamma can change delta rapidly as price moves.
Gamma: rate of change of delta. Long straddles/strangles benefit from positive gamma — they gain sensitivity as the underlying moves, amplifying directional gains.
Vega: sensitivity to implied volatility. Long both-sides positions are long vega — they gain value if implied volatility rises after entry.
Theta: sensitivity to time decay. Long option buyers pay theta; positions lose value as expiration approaches if the underlying doesn't move enough.
Rho: sensitivity to interest rates — typically a minor factor for short-dated equity or crypto options.

Implied volatility is especially important: higher implied volatility raises option premiums; buying both options benefits if implied volatility increases post-entry or if realized volatility exceeds the implied level priced in at purchase.

Exercise, assignment and settlement mechanics

Exercise and settlement rules vary by product:

American-style equity options can be exercised any time before expiration. If you hold a long option and it is in the money near or at expiration, standard broker conventions (auto-exercise thresholds) may apply automatically.
European-style options (common for some indices) can only be exercised at expiration.
Settlement may be physical delivery (actual shares exchanged) for many equity options or cash-settled for certain indices and some crypto products.
Automatic exercise: many brokers auto-exercise ITM options at expiration if they exceed a set dollar threshold; confirm your broker’s rules to avoid unexpected positions or assignments.
Assignment risk affects sellers, not buyers. If you sell options as part of a multi-leg, you may be assigned if the option buyer exercises.

Because buyers of both a call and a put typically close positions prior to exercise, understanding settlement prevents surprises — especially near expiration or around corporate actions (dividends, splits). For crypto options traded on derivatives exchanges, settlement conventions differ across venues — some use cash settlement in USD or stablecoins, others may use physical settlement in the token.

Practical execution considerations

Before placing a trade that buys both sides, check these practical items:

Brokerage approvals: most brokers require options trading approval; buying options typically needs a lower level of approval than selling uncovered options. Confirm you have permissions to buy calls and puts on the same underlying.
Margin and cash: buyers pay premiums in cash; sellers and more complex multi-legs may require margin. Confirm account funding and margin impact.
Contract sizes: remember 100-share multipliers for standard equity options; that multiplies premiums into real dollar exposure.
Liquidity and bid-ask spreads: wider spreads increase execution cost. Prefer liquid strikes and expirations to reduce slippage when entering or exiting both legs.
Order types: use limit orders to reduce slippage; avoid market orders for illiquid strikes. Consider simultaneous or multi-leg orders if your broker supports them to ensure both legs are filled together.
Position management: plan exit rules — close or roll positions before expiration, or set alerts for breakeven or target moves. Consider scaling into or out of positions if permitted.

Crypto options vs equity options

Buying a call and a put on the same crypto token follows the same conceptual logic as equities, but practical differences matter:

Underlying products: crypto options are available for major tokens (for example, BTC or ETH) on derivatives platforms and for some institutional regulated products; listed options for individual crypto tokens on regulated exchanges are less common than equity options.
Settlement conventions: many crypto options are cash-settled or settled in the underlying token; check the exchange’s rules.
Counterparties and clearing: listed equity options trade through regulated exchanges with central clearinghouses; some crypto options trade on centralized derivatives platforms with different counterparty mechanics.
Liquidity and implied volatility: crypto options often show higher implied volatility and can have different liquidity patterns compared with equities, affecting pricing and execution costs.
Recommended platform: for traders interested in crypto options and integrated wallet support, consider Bitget and Bitget Wallet for trading, custody and derivative access while observing platform-specific rules and risks.

Risks and limitations

Buying both a call and a put is not risk-free. Main risks include:

Total premium loss: if the underlying remains near the strike(s) and both options expire worthless, the buyer loses the entire premium paid for both options.
Time decay (theta): options lose value over time, particularly short-dated options. Rapid time decay can eliminate expected profits if price moves are delayed.
Volatility crush: implied volatility often spikes before scheduled events and drops sharply afterward. If you buy options near peak implied volatility, a volatility crush can hurt the position even if price moves somewhat.
Liquidity and slippage: wide bid-ask spreads and low open interest can make entries and exits costly or difficult.
Assignment risk: sellers face assignment risk, not buyers — but multi-leg trades that involve sold legs can be assigned unexpectedly.
Tax and margin complexities: options generate events taxable in different ways and may require margin. Consult a tax professional for guidance.
Model and execution risk: theoretical pricing models can differ from actual execution prices; large orders can suffer market impact.

Tax and regulatory considerations (high-level)

Tax treatment of options differs by jurisdiction. In the United States:

Profits and losses from listed equity options are generally treated as capital gains or losses, governed by holding period rules and specific IRS guidance.
Certain futures and broad-based index options may fall under Section 1256 tax treatment with 60/40 long-term/short-term character; this does not usually apply to single-stock options.
Crypto derivatives may have different tax rules and reporting requirements; consult local tax guidance and a tax professional.

Regulatory rules also govern who can trade options, disclosure, and reporting. Confirm your broker or platform’s compliance and licensing, and ensure you meet their verification and suitability requirements.

Example scenarios

Below are two concise numeric examples that illustrate how a long straddle and a long strangle can work. These examples assume standard 100-share contract multipliers and do not include commissions or fees.

Example 1 — Long straddle (ATM)

Assume stock XYZ trades at $50. You buy one XYZ 50-strike call and one XYZ 50-strike put that expire in 30 days. The call premium is $2.50 and the put premium is $2.50. Total premium paid = $2.50 + $2.50 = $5.00 per share. With a 100-share contract, your total cost = $5.00 * 100 = $500.

Breakeven points:

Upside breakeven = strike + total premium = $50 + $5 = $55.
Downside breakeven = strike - total premium = $50 - $5 = $45.

If at expiration XYZ is $60, the call is worth $10 (intrinsic) and the put is worthless; profit = $1,000 intrinsic - $500 premium = $500. If at expiration XYZ is $40, the put is worth $10 and profit similarly equals $500. If XYZ remains at $50, both expire worthless and your loss = $500 (the premium).

Example 2 — Long strangle (OTM)

Assume stock ABC trades at $100. You buy a 95-strike put for $1.20 and a 105-strike call for $1.50, both 30 days to expiration. Total premium = $2.70 per share. With one contract of each, the total cost = $270 per combined position (100-share multiplier).

Breakeven points:

Upside breakeven = call strike + total premium = $105 + $2.70 = $107.70.
Downside breakeven = put strike - total premium = $95 - $2.70 = $92.30.

This strangle costs less than an ATM straddle but needs a larger move (below $92.30 or above $107.70) to be profitable. Maximum loss = $270 if ABC expires between $95 and $105.

Alternatives and related strategies

Buying both sides is one way to trade volatility. Alternatives include:

Buying a single directional option (call or put) — cheaper and directional, but requires correct direction.
Protective put — buy a put while holding stock to limit downside.
Covered call — sell a call while holding stock to generate income but cap upside.
Synthetic positions — buy call + sell put (synthetic long) or other synthetics that replicate stock exposure.
Spreads (debit or credit) — limit risk and cost by combining bought and sold options with different strikes.
Volatility-neutral strategies (iron condor, butterfly) — aim to profit from low volatility or capture decay.

Frequently asked questions (FAQ)

Q: Can my broker let me buy both a call and a put on the same stock?

A: Usually yes, provided you have options trading approval from your broker. Buying options typically requires a lower approval level than selling uncovered options. Check your broker’s options agreement and approval levels.

Q: Can I buy the same strike and expiration for both call and put?

A: Yes. Buying the same strike and expiration is the definition of a straddle.

Q: Do options exist for all stocks?

A: Not all stocks have listed options. Most liquid, large-cap U.S. equities have options, but smaller-cap or thinly traded stocks may not. Check the option chain for availability.

Q: Can I do this with crypto?

A: Yes. Crypto options are available for major tokens on derivatives exchanges and for some regulated venues. Settlement, liquidity and product terms vary by platform. For integrated crypto trading and custody, consider Bitget and Bitget Wallet, and confirm the exchange’s option contract specifications.

Q: When is a straddle preferable to a strangle?

A: Use a straddle when you expect a significant move but want symmetric sensitivity around the current price (ATM exposure) and can afford higher premiums. Use a strangle when you expect a big move but want a lower upfront cost and can accept needing a larger move to be profitable.

Best practices and checklist before placing the trade

Before buying both a call and a put on the same stock, run this checklist:

Confirm the exact phrasing: "can you buy calls and puts on the same stock" — yes, then verify availability on your platform.
Check the option chain liquidity (open interest, volume) for chosen strikes and expiration.
Compare implied volatility to historical volatility to assess whether options are expensive or cheap.
Set position size and define maximum acceptable loss (total premium paid).
Confirm broker permissions, margin or cash requirements, and auto-exercise rules.
Plan entry and exit rules (target price, stop, time limit) and consider using limit or multi-leg orders.
Account for commissions, fees and taxes in P&L calculations.
Consider paper trading or a small initial position to test execution and slippage.
