Implied volatility in options markets rises ahead of earnings as traders price in event uncertainty. This makes puts more expensive to buy in the week before an announcement.
After the announcement, IV typically collapses (IV crush), reducing option value even if the stock moves as expected.
Buying a protective put several weeks before earnings, when IV is at normal levels, usually costs less and still covers you through the event.
For persistent protection across multiple earnings cycles, long-dated LEAPS puts are often more cost-efficient than rolling short-term puts each quarter.

Why earnings events matter for concentrated positions
A quarterly earnings report can move a stock 10%, 20%, or more in a single session. For a holder with 80% of their net worth in one stock, an earnings miss that sends the stock down 25% is not a portfolio event. It is a personal financial crisis.
Protective puts are one of the few instruments that let you hold the stock through earnings and define your worst-case outcome in advance. But the options market prices in earnings risk, which makes the timing of when you buy protection meaningful.
What implied volatility does around earnings
Every publicly traded options market has an implied volatility (IV) for each expiration date. IV is the market's expectation of how much the stock will move over that period, derived from option prices. It is not a prediction; it is a consensus expectation priced into the premium.
In the weeks leading up to an earnings announcement, IV for options expiring shortly after the event rises. Market makers are pricing in the binary nature of the event: the stock could move sharply in either direction. The closer to the announcement date, the more elevated the IV typically becomes.
As an illustrative example: a tech stock with a normal IV of 35% might see its near-term IV rise to 55% or higher in the week before earnings. That means puts expiring shortly after earnings cost roughly 50% more than they would during a non-event period, all else being equal.
IV crush: the post-earnings deflation
Once earnings are released, the uncertainty is gone. Whether the stock moved a lot or a little, the event has passed. IV quickly returns to its normal non-event level, a rapid drop called IV crush.
This has a direct effect on put values. If you bought a put just before earnings, paid the elevated premium, and then the stock fell 5%: your put gained intrinsic value from the stock move, but lost extrinsic value from the IV collapse. The net result can be smaller than expected, or even a loss if the stock only fell slightly and IV fell sharply.
For a concentrated-position holder, this dynamic matters but is not the primary concern. You are not trying to profit from the put; you are protecting against a catastrophic move. If the stock falls 25%, the intrinsic gain on the put far exceeds any IV deflation. The issue mostly stings on small-to-moderate moves.
Timing strategy: when to buy pre-earnings protection
Buying several weeks before earnings (often most efficient)
If you know an earnings date is coming (companies announce their earnings calendar in advance), buying protection three to six weeks before the announcement gets you in before IV begins its pre-earnings climb. You pay a lower premium and still have coverage through the event.
The trade-off: you are paying time premium for those extra weeks. If the stock is perfectly stable heading into earnings and then has a benign report, you paid for coverage you did not need. But for a concentrated-position holder, that is the purpose of insurance.
Buying the week before earnings (most expensive)
Waiting until the week before earnings means you are paying the highest IV premium. The protection is still valid; you are paying more for it. If your only concern is the earnings event specifically, you can do this and sell or let expire the put shortly after the announcement.
Buying after earnings (cheapest, but coverage is for the next cycle)
Buying a put immediately after an earnings announcement, when IV has crushed back to normal levels, is the cheapest time to buy coverage for the next quarter. You had no protection for this quarter's report, but you can set up protection at a favorable premium for the period ahead.
This is the approach embedded in a systematic quarterly hedging program: buy after each earnings report, hold through the next one, repeat.
Comparison: timing approaches
| Timing | IV level | Put cost | Coverage through event? | Best for |
|---|---|---|---|---|
| 3–6 weeks before earnings | Normal to slightly elevated | Lower | Yes | Efficient pre-earnings hedge |
| 1 week before earnings | Elevated | Higher | Yes | Late-stage protection, urgent need |
| Day of earnings | Peak | Highest | Post-release only (announcement already in progress) | Generally poor timing for hedging |
| 1–2 days after earnings | Crushed to normal | Lowest | Next earnings cycle | Systematic quarterly program |
Long-dated LEAPS: covering multiple earnings cycles
Buying a one-year or two-year put (a LEAPS, or Long-term Equity AnticiPation Security) provides coverage through multiple earnings cycles without needing to roll quarterly. The upfront cost is higher in absolute terms, but on a per-month basis it is often lower than buying a new short-dated put every quarter.
LEAPS are also less affected by the IV spike before any single earnings event because the event risk is a smaller fraction of the total remaining time on the option. A two-year LEAPS absorbs the IV crush from one quarter's earnings with minimal impact on its overall value.
For RSU holders who want persistent, low-maintenance coverage across a multi-year horizon, LEAPS can be a more efficient structure than rolling short-dated puts repeatedly.
What does earnings hedging actually cost?
Put cost depends on the stock's baseline IV, the earnings-specific IV bump, your chosen strike, and tenor. As an illustrative example for a high-volatility tech stock:
- Buying a three-month 10% OTM put three weeks before earnings: illustratively 3% to 5% of notional
- Buying the same put one week before earnings: illustratively 4.5% to 7.5% of notional
- A one-year LEAPS put at 10% OTM, bought after the previous quarter's earnings: illustratively 6% to 10% of notional, covering four earnings cycles
Illustrative only. Actual premiums depend on live market conditions and specific contract terms.

Insider trading and company trading policies
If you hold company stock as an insider (officer, director, or large holder), your ability to buy options during certain periods may be restricted by your company's trading policy and by Rule 10b-5. Many companies have blackout periods around earnings that prohibit options transactions. Always confirm with your company's legal counsel before placing any hedge on insider shares.
A 10b5-1 plan, which pre-schedules trades when you are not in possession of material non-public information, can be structured to include systematic option purchases. Consult a securities attorney to set one up.
Frequently asked questions
Earnings announcements carry outcome uncertainty. The stock might beat, miss, or guide in ways that move it sharply in either direction. Options market makers price in that event risk by raising implied volatility ahead of the announcement, which raises option premiums. The closer to earnings, the more elevated IV typically becomes.
IV crush is the sharp drop in implied volatility that typically follows an earnings announcement. Once the event has passed, the uncertainty is resolved and option sellers no longer need to charge for it. If you bought a put just before earnings, even if the stock moves somewhat in your favor, the collapse in IV may reduce the option's value. Options bought primarily to profit from the earnings outcome can lose value even when the directional bet is right, if the IV deflation overwhelms the intrinsic gain.
Buying several weeks before the earnings announcement, when IV is still at normal levels, typically gives you cheaper coverage that still extends through the event. The trade-off is that you pay time premium for those additional weeks. If you buy the week of earnings, you pay elevated IV. If you buy after earnings, the event has passed and the put covers you through the next cycle at lower cost, but you had no protection during the announcement.
This page focuses on hedging an existing concentrated position, not on trading options for profit. A holder of a concentrated stock position is not trying to profit from earnings; they are trying to protect wealth they already have. Whether a stand-alone options trade on earnings is profitable is a separate and complex question not addressed here.
That depends on the put cost relative to the risk each earnings event represents. High-volatility stocks have more event risk and thus more expensive earnings puts. Some holders buy persistent long-dated protection (LEAPS) that covers multiple earnings cycles, which can be more cost-efficient than buying a new short-term put each quarter. Others hedge only when the stock is highly valued or when their financial plan cannot absorb a large drawdown.
The BallastX Hedging Cost Index shows current annualized put-cost benchmarks across equity-compensation stocks. Because IV rises into earnings, the cost index captures when protection is relatively expensive or cheap. The BallastX Stress Test lets you model drawdown scenarios and estimated hedge costs for your specific position size.
