Options Contracts

An options contract gives the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price (the strike price) before or on a specific expiration date. This flexibility distinguishes options from futures, which obligate both parties to complete transactions. As derivatives, options derive their value from underlying assets like stocks, indexes, currencies, or commodities.

Two basic option types exist: call options grant the right to buy the underlying asset, while put options grant the right to sell. Buyers pay a premium upfront to sellers (also called writers) for this right. If market conditions make exercising the option unprofitable, buyers simply let it expire worthless, losing only the premium paid. This asymmetric risk profile—limited loss potential with theoretically unlimited profit potential—makes options powerful but complex tools for hedging, speculation, and income generation.

How Options Work

Basic Mechanics

When you purchase an option, you pay a premium to the seller for the contract. This premium represents the maximum loss you can incur as a buyer. The option specifies the underlying asset, strike price (the price at which you can buy or sell), expiration date, and contract size (typically 100 shares for stock options).

For example, you might buy a call option on Apple stock with a $150 strike price expiring in two months, paying a $5 premium per share ($500 total for one contract covering 100 shares). If Apple trades above $150 before expiration, you can exercise the option to buy 100 shares at $150 each, regardless of the actual market price. If Apple never reaches $150, you simply let the option expire, losing your $500 premium.

The Four Basic Positions

Long call: Buying a call option benefits from upward price movements in the underlying asset. Your maximum loss equals the premium paid, while profit potential is theoretically unlimited as prices rise. This position replaces buying the stock directly with less capital and defined risk.

Short call: Selling a call option (without owning the underlying stock, called a "naked" call) generates immediate premium income but exposes you to theoretically unlimited losses if prices rise sharply. Selling covered calls (when you own the underlying stock) limits this risk but caps your upside at the strike price plus premium received.

Long put: Buying a put option profits from declining prices in the underlying asset. Your maximum loss equals the premium paid, while profit potential extends to the strike price minus premium (as prices can't fall below zero). Investors use puts to hedge stock holdings or speculate on declines.

Short put: Selling a put option generates immediate premium income but obligates you to buy the underlying asset at the strike price if the buyer exercises. This strategy works well when you're willing to own the stock at the strike price or believe prices will remain stable or rise.

Option Pricing Components

Intrinsic Value

Intrinsic value represents the immediate exercise value. A call option has intrinsic value when the underlying asset's price exceeds the strike price. If Apple trades at $160 and you hold a $150 strike call, the intrinsic value is $10. A put option has intrinsic value when the strike price exceeds the underlying price.

Options with intrinsic value are "in the money" (ITM). Options where strike price equals current price are "at the money" (ATM). Options with no intrinsic value are "out of the money" (OTM). Only in-the-money options have intrinsic value; at-the-money and out-of-the-money options have zero intrinsic value but might still have substantial time value.

Time Value and Theta Decay

Time value represents the premium above intrinsic value, reflecting the possibility that the option will move in the money or deeper in the money before expiration. Even out-of-the-money options have time value because price movements might create intrinsic value. An Apple $170 call might trade for $3 when the stock is at $160, with $0 intrinsic value and $3 time value.

Time value erodes as expiration approaches, a phenomenon called theta decay. This decay accelerates in the final weeks before expiration. Options lose roughly one-third of their time value in the last month, making them risky for buyers but profitable for sellers who can collect premiums as time passes. All options expire with zero time value—only intrinsic value remains at expiration.

Volatility and Vega

Implied volatility dramatically impacts option prices. Higher volatility increases option premiums because greater price swings create more chances for options to move in the money. During market turmoil, implied volatility spikes, causing option premiums to expand even if underlying prices remain unchanged.

The sensitivity of option prices to volatility changes is called vega. When implied volatility rises from 20% to 30%, an option might gain $2 in value from vega alone, independent of underlying price changes. Conversely, when volatility contracts after market calm returns, option premiums decline. Successful options trading requires understanding both directional views and volatility expectations.

Delta and Other Greeks

Delta measures how much an option's price changes per $1 change in the underlying asset. At-the-money options have deltas around 0.50, meaning they gain or lose roughly 50 cents per dollar move in the stock. Deep in-the-money options approach deltas of 1.00, moving nearly dollar-for-dollar with the stock. Out-of-the-money options have low deltas, responding minimally to small price changes.

Gamma measures delta's rate of change, showing how quickly options accelerate in responsiveness to price moves. Rho reflects interest rate sensitivity, typically minimal for short-term options. Together, these "Greeks" help traders assess risk and construct sophisticated strategies combining multiple options to create specific payoff profiles.

Options Strategies

Basic Strategies

Protective put: Buying put options while holding stock provides downside protection similar to insurance. If stock prices fall, put gains offset stock losses. If prices rise, you lose only the put premium while benefiting from stock appreciation. This strategy lets investors maintain upside potential while limiting downside risk during uncertain periods.

Covered call: Selling call options against stock you own generates immediate income from premiums. If the stock remains below the strike price, you keep the premium and the stock. If prices rise above the strike, you're obligated to sell shares at the strike price, capping your upside. This works well in neutral to slightly bullish markets, enhancing returns through premium income.

Cash-secured put: Selling put options while holding cash equal to the potential purchase obligation generates income. If prices stay above the strike, you keep the premium. If assigned, you buy the stock at the strike price—presumably a price at which you're happy to own it. This strategy effectively gets paid to place a buy order.

Intermediate Strategies

Vertical spreads involve buying one option and selling another at a different strike price with the same expiration. A bull call spread buys a lower-strike call and sells a higher-strike call, reducing cost but capping maximum profit. This defined-risk strategy profits from moderate upward movements. Bear put spreads work similarly for downward expectations, buying higher-strike puts and selling lower-strike puts.

Calendar spreads (also called time spreads) involve selling a near-term option and buying a longer-term option at the same strike price. This profits from theta decay of the short-term option while maintaining longer-term exposure. Calendar spreads benefit from stable prices and work best when implied volatility is relatively low but expected to increase.

Advanced Strategies

Iron condors combine a bull put spread and a bear call spread, creating positions that profit when prices remain range-bound. You collect premium from both spreads upfront, keeping it all if the underlying stays between the two short strikes. This strategy suits low-volatility environments where prices are expected to move sideways.

Straddles involve buying both a call and put at the same strike price and expiration, profiting from significant moves in either direction. This volatility strategy costs substantial premium but can generate large profits if the underlying makes a strong move. Strangles work similarly but use different strikes for calls and puts, costing less but requiring larger moves to profit.

Advantages of Options

Defined Risk for Buyers

Options buyers face limited downside risk equal to premiums paid, regardless of how dramatically underlying prices move against positions. This asymmetric risk profile provides peace of mind unavailable with stocks or futures. You can make aggressive directional bets knowing maximum losses, enabling position sizing without fear of catastrophic losses.

Leverage and Capital Efficiency

Options provide substantial leverage, controlling large amounts of stock with relatively small premium payments. A $5 call option controls $15,000 worth of stock (100 shares at $150) for just $500, creating 30:1 leverage. This capital efficiency lets investors deploy funds across multiple positions or strategies while maintaining diversified portfolios.

Flexibility and Strategy Variety

Options enable sophisticated strategies impossible with stocks alone. You can profit from falling prices without short selling, generate income in sideways markets, protect holdings from downturns, or create positions profiting from volatility changes regardless of direction. This flexibility allows tailoring strategies precisely to market views and risk tolerance.

Hedging Capabilities

Portfolio managers use options to protect against temporary market uncertainty without liquidating holdings and triggering taxes. Buying put options on portfolio holdings or index positions provides insurance against declines while maintaining upside potential. This hedging proves more flexible than simply selling and repurchasing positions when concerns pass.

Disadvantages and Risks of Options

Complexity

Options require understanding strike prices, expiration dates, volatility, time decay, and how these factors interact. The Greeks, spread strategies, and assignment risks create learning curves discouraging to beginners. Misunderstanding these mechanics leads to unexpected outcomes—sellers face assignment obligations, buyers watch premiums evaporate from theta decay, and volatility changes create counterintuitive price movements.

Time Decay for Buyers

Theta decay constantly erodes option value, creating a headwind for buyers. You can be directionally correct about price movements but still lose money if moves don't happen quickly enough or are too small to overcome premium decay. Unlike stocks that can be held indefinitely, options have finite lifespans requiring not just correct directional views but also proper timing.

Seller Risk Exposure

While buyers face limited losses, sellers face substantial or unlimited risk. Naked call sellers expose themselves to theoretically unlimited losses if prices rise dramatically. Even cash-secured put sellers can lose the full strike price minus premium if stocks become worthless. Many beginning traders sell options for premium income without fully appreciating these risks, facing devastating losses during volatile markets.

Bid-Ask Spreads and Liquidity

Less actively traded options have wide bid-ask spreads, making entries and exits costly. You might pay $5.20 when buying an option quoted at $5.00 bid and $5.40 ask, immediately losing $0.20 per share. Exiting positions faces the same spread, making round-trip costs substantial. Stick to liquid options on well-traded stocks or indexes to minimize these transaction costs.

Options vs. Other Investment Instruments

Options differ fundamentally from owning stocks. Stock ownership provides unlimited upside potential, dividends, and voting rights with no expiration. Options have finite lifespans, don't pay dividends (though dividend expectations affect pricing), and require active management as expirations approach. However, options provide leverage and defined risk unavailable with direct ownership.

Compared to futures, options offer asymmetric risk profiles—buyers can't lose more than premiums paid, while futures expose both parties to full contract value. Options cost premium upfront while futures use margin systems. These differences make options preferable when wanting to limit downside while retaining upside potential.

Getting Started with Options Trading

Education and Paper Trading

Before risking capital, thoroughly study option mechanics, pricing factors, and strategy construction. Read options education materials provided by exchanges like CBOE and brokers. Practice with paper trading accounts to understand how positions behave through various market conditions without financial risk. Experience how theta decay affects values, how volatility changes impact premiums, and how different strategies perform.

Starting Simple

Begin with basic strategies like covered calls on stocks you own or cash-secured puts on stocks you'd like to own. These relatively straightforward approaches generate income while limiting risk compared to naked option selling or complex multi-leg strategies. As you gain experience and understanding, gradually explore more sophisticated strategies.

Risk Management

Never risk more than 1%-2% of portfolio value on any single options trade. Options' time-limited nature and leverage make strict position sizing essential. Diversify across multiple positions and strategies rather than concentrating capital in one or two trades. Set maximum loss limits per trade and overall portfolio drawdown limits, exiting positions when hit regardless of conviction.
