Practical Trading — Options Tutorial

Earnings Plays

Every quarter, big companies report earnings and their stocks can gap 5-15% overnight. Options traders love these high-conviction volatility events.

The most straightforward approach: Long Straddle — buy a Call and a Put at the same strike, betting on magnitude, not direction.

Case study: NVDA Q3 2024 earnings

Day before the report, NVDA trades at $480. You buy:

1x $480 Call, premium $18
1x $480 Put, premium $16
Total cost: $34/share = $3,400

NVDA needs to move above $514 or below $446 for you to profit. That’s a 7% move in either direction.

IV Crush

Before earnings, everyone knows the stock will move. That expectation is already priced into the options — implied volatility (IV) spikes. After the report drops, uncertainty vanishes. IV collapses. Option prices shrink.

Even if NVDA rallies 5% to $504, your Call’s intrinsic value is only $24 — but you paid $34. IV Crush ate your profit.

Sizing rules for earnings plays:

Cap total outlay at 2% of your account — earnings are coin flips, not analytical predictions
Use a Strangle instead of a Straddle to lower cost: buy OTM Call and OTM Put
Consider the other side: sell Straddles/Strangles to harvest IV Crush (but your risk exposure is large)

0DTE (Zero Days to Expiration)

0DTE options expire the same day you trade them. SPX and SPY now have daily expirations, and 0DTE trades account for over 40% of total US options volume.

Why traders love them:

Premiums are dirt cheap — $50 to $500 per contract
Leverage is extreme — a 1% move in the underlying can double the option
No overnight risk — everything settles by close

Gamma risk — the double-edged sword

On expiration day, Gamma explodes for ATM options. Delta swings violently: a small price move can push Delta from 0.5 to 0.8, or crush it to 0.2.

Two consequences:

Right on direction — profits compound faster than you’d expect
Wrong on direction — premium goes to zero in minutes

When 0DTE works:

Scenario	Strategy	Logic
Clear direction in first 30 min	Buy ATM Call/Put	Ride Gamma acceleration
Pre-FOMC announcement	Buy Strangle	Bet on vol, not direction
Late-day range-bound action	Sell Iron Condor	Harvest Theta decay

Hard rule: never put more into 0DTE than you’re prepared to lose entirely that day. There’s no “stop out and recover” — expiration is settlement.

The Wheel Strategy

The Wheel is the most practical options strategy for retail traders. The premise: you already want to buy a stock at a lower price — so get paid to wait.

The full cycle:

Step 1: Sell a Cash-Secured Put Step 2: Get assigned → you now own the stock Step 3: Sell a Covered Call Step 4: Get called away → stock sold → back to Step 1

Worked example: Running the Wheel on AAPL

AAPL is trading at $175. You have $17,500 in cash.

Week 1: Sell Put

Sell 1x $170 Put, 30 DTE, collect $3.50/share = $350
If AAPL stays above $170 at expiry: Put expires worthless, $350 is yours. Annualized return = ($350 / $17,000) x 12 = 24.7%
If AAPL drops to $165: You buy 100 shares at $170. Effective cost basis = $170 - $3.50 = $166.50

Week 5: You own 100 shares of AAPL at $166.50

Sell 1x $175 Covered Call, 30 DTE, collect $2.80/share = $280
If AAPL stays below $175 at expiry: Call expires worthless, $280 is yours, keep the shares
If AAPL rallies to $180: Shares called away at $175. Total profit = ($175 - $166.50) + $2.80 + $3.50 = $14.80/share

Wheel strategy ground rules:

Only run the Wheel on stocks you genuinely want to own
Set strikes 5-10% OTM to balance premium income vs. assignment probability
Avoid earnings weeks — high IV looks tempting, but a gap down can stick you with shares well above market price

Portfolio Hedging

Protective Put

You hold 100 shares of TSLA at $250 and worry about a near-term drop, but don’t want to sell.

Buy 1x $240 Put, premium $6 = $600.

This is insurance: below $240, the Put pays out. Above $240, you only lose the $600 premium.

Cost: $600 / $25,000 = 2.4% per quarter. Not cheap.

Collar Strategy

Protective Put too expensive? Add a twist: sell an OTM Covered Call and use that premium to subsidize the Put.

Hold 100 shares TSLA @ $250
Buy $240 Put, pay $6
Sell $265 Call, collect $4
Net cost: $2/share = $200

The tradeoff: you give up gains above $265. Your return is locked between $240-$265, but downside protection costs just $200.

When to use a Collar: You hold a concentrated single-stock position (like company equity), can’t sell in the near term, but need downside protection.

Position Sizing

Simplified Kelly Criterion

The Kelly formula tells you the optimal bet size:

f = (bp - q) / b

b = odds ratio (expected gain / expected loss)
p = win probability
q = 1 - p

Say your strategy wins 55% of the time, with average gains 1.5x average losses:

f = (1.5 x 0.55 - 0.45) / 1.5 = 0.25

Kelly says bet 25%. But Kelly is the theoretical optimum — in practice, use half-Kelly (12.5%) for a safer ride.

Hard Limits

Rule	Cap
Single options trade	2-5% of account
All positions in one underlying	10% of account
Naked short option margin	20% of account
Total 0DTE exposure per day	1% of account

These aren’t suggestions. They’re survival rules. No single trade should deal a blow your account can’t recover from.

Building a Trade Plan

Opening a position without a trade plan is driving without a map.

Entry Criteria

Before opening any position, answer three questions:

Why now? What event or signal is triggering this trade?
Why this strategy? Long Call, Short Put, or a spread?
Where’s IV? IV Rank > 50 favors selling strategies. IV Rank < 30 favors buying strategies.

Exit Rules

Write your exit conditions at the time you open the trade:

Take profit: close at 50-75% of max profit
Stop loss: close at 50% of capital deployed (or 2x the premium paid)
Time stop: close 7 days before expiration regardless of P&L (unless you want assignment)

Trade Journal

Record these fields for every trade:

Field	Content
Date	Open / close dates
Underlying	AAPL, TSLA, SPY…
Strategy	Long Call, CSP, Iron Condor…
Entry reason	Technical breakout / earnings anticipation / IV elevated…
Entry price	Premium or net debit/credit
Planned exit	Specific take-profit / stop-loss / time-stop numbers
Actual exit	Final closing price
P&L	Dollar amount and percentage
Review	What went right? What went wrong?

The journal’s value isn’t in the recording — it’s in the review. Look at it monthly. Spot the mistakes you keep repeating.

Quick Reference

Scenario	Recommended Strategy	Key Risk
Bullish on a stock, want leverage	Long Call	Theta decay; needs a big move
Want to buy a stock cheaper	Cash-Secured Put (Wheel)	Stock plummets; forced to buy high
Own stock, want extra income	Covered Call (Wheel)	Capped upside
Bet on earnings volatility	Long Straddle/Strangle	IV Crush
Intraday directional trade	0DTE Call/Put	Gamma risk; total loss likely
Protect a long position	Protective Put / Collar	Insurance cost / capped upside
IV is elevated, want to sell	Short Strangle / Iron Condor	Tail risk; margin required

Exercise

Scenario: You have a $50,000 options account. You hold 200 shares of AMZN (cost basis $180/share). AMZN is currently at $185. AMZN reports quarterly earnings next Thursday. You want to protect your position from an earnings-driven crash, preserve upside potential, and take advantage of the elevated IV environment.

Design a combined approach:

What strategy do you use to protect the position?
How do you exploit the high-IV environment?
What is the position size and risk exposure for each leg?
