Selling Options Before Earnings

Selling options before earnings announcements is one of the most widely used strategies among active options traders. The premise is straightforward: implied volatility spikes before earnings as uncertainty is priced in, and collapses after the announcement when that uncertainty resolves. Selling options before the event and buying them back after captures this IV collapse as profit.

Done correctly, with proper structure and sizing, earnings premium selling has a documented statistical edge. This article explains exactly how it works.

Why selling before earnings has an edge

The volatility risk premium is at its most concentrated around earnings events. In the days before an announcement, market participants bid up options prices beyond what the actual stock move typically warrants. Studies consistently show that stocks move less than the implied move on roughly 65 to 70% of earnings events.

This means:

• The options market prices in more movement than actually occurs the majority of the time
• Sellers who collect the inflated pre-event premium are on the statistically favored side of that trade
• The edge is not directional. You do not need to predict whether the stock goes up or down. You need the stock to move within a range.

The structural reason for this overpricing: hedgers and portfolio managers buy options before earnings for protection, regardless of price. Their demand inflates premiums above fair value consistently, creating the edge that sellers harvest.

The mechanics of the profit

When you sell a credit spread or iron condor before earnings, you collect a net premium immediately.

After the announcement, IV crushes from its elevated pre-event level back toward the stock's normal baseline IV. This deflates the value of the options you sold. You buy them back for less than you collected.

Example:

MSFT at $415, earnings tomorrow after close. You sell an iron condor: Sell $430 call, buy $435 call (bear call spread) Sell $400 put, buy $395 put (bull put spread) Net credit collected: $1.80 per share ($180 per condor)

MSFT reports. Beats estimates. Stock gaps up 5% to $436 at open. IV crushes from 55% to 18%.

Wait, the stock is at $436, above the $430 short call. Let's say instead: MSFT beats, stock moves to $421 (2% gain). Within the profit range.

Next morning, with IV crushed, the condor is worth approximately $0.40. You close for $0.40 debit. Profit: $1.80 - $0.40 = $1.40 per share ($140 per condor).

The three main structures for selling before earnings

Iron condor: Sell OTM call spread above and OTM put spread below the stock. Defined risk on both sides. Profits if the stock stays within the range. The most popular earnings premium-selling structure for retail traders because the max loss is known before entry.

Bull put spread: Sell OTM put spread below the stock only. Directionally biased (mildly bullish). Collects elevated put premium amplified by volatility skew. Defined risk.

Bear call spread: Sell OTM call spread above the stock only. Directionally biased (mildly bearish). Defined risk.

Short strangle: Sell OTM call and OTM put at different strikes without the protective long options. Collects significantly more premium than an iron condor but carries undefined risk. Not recommended for most retail traders around binary events.

Choosing your strikes correctly

The implied move is your primary guide for strike placement.

Calculate the implied move: approximately equal to the ATM straddle price. If MSFT is at $415 and the ATM straddle costs $18, the implied move is roughly $18 or about 4.3%.

Place your short strikes at or beyond this implied move level:

• Short call at $415 + $18 = $433 or higher
• Short put at $415 - $18 = $397 or lower

This means the stock needs to move more than the implied move to breach your short strikes. Historically, this happens roughly 32% of the time (one standard deviation).

For higher probability, go wider: 1.2 to 1.5 times the implied move. You collect less premium but give yourself more buffer.

Confirming the edge before entering

Not every earnings event has a strong selling edge. Before entering, confirm:

1. Implied move vs historical average: the current implied move should be meaningfully above the average actual move over the last 6 to 8 quarters. A gap of 20% or more is a strong signal.

2. IV rank above 60: the overall IV elevation should be confirmed, not just the near-term spike.

3. Liquid options chain: bid-ask spreads under $0.10 on near-the-money options, open interest above 1,000 contracts at your target strikes.

4. No unusual risk factors: new management, pending regulatory decision, or ongoing legal matters can create binary outcomes that break historical patterns.

Sizing and risk management

Earnings are binary events. Size every earnings trade at 1 to 2% of portfolio in maximum risk capital.

This is smaller than a typical non-earnings credit spread. The reason: you cannot adjust during the event. Once the stock moves after hours on the announcement, your position is set. The only risk control you had was at entry, through position sizing.

With an iron condor sized at 1 to 2% risk, a max loss on any individual trade is manageable. With positions sized at 10%, one bad earnings can wipe out weeks of gains.

What to do when the trade goes wrong

Occasionally a stock makes a move far larger than the implied move, pushing through your short strikes and toward max loss territory.

When this happens:

If the stock is between your short and long strikes at the open: You have a partial loss. Assess whether the stock is stabilizing or continuing to trend. If stabilizing, you can sometimes hold for partial recovery as remaining time value decays. If continuing to trend, close and take the managed loss.

If the stock is beyond your long strike: Close immediately. You are at or near max loss. Do not hold hoping for a reversal. The defined risk structure exists precisely for this scenario. Take the loss, preserve your capital, and move to the next trade.

What not to do: Roll the position aggressively into undefined-risk structures to avoid taking a loss. This converts a defined-risk loss into a potentially much larger undefined-risk position. The discipline to take a defined max loss is what separates profitable options traders from those who turn small losses into large ones.

Building a repeatable process

The best earnings premium sellers treat it as a systematic process, not a series of individual predictions:

1. Every week, review the Earnings Calendar for the upcoming two weeks
2. Filter for liquid names with IV rank above 60
3. Check implied move vs historical average on each candidate
4. Enter iron condors 2 to 3 days before announcement on qualifying setups
5. Exit next morning after announcement
6. Track results across all trades

Over 20 to 30 earnings events, the statistical edge in the volatility risk premium becomes visible in the results. No individual trade defines the strategy. The process does.
