Why Earnings Season Changes the Options Calculus

Quarterly results introduce a specific, known source of potential large price movement, along with a
corresponding, predictable rise in implied volatility ahead of the announcement. This combination creates unique
opportunities and risks that don’t apply during ordinary trading days, requiring a different approach than typical
options trading outside of results season.

Understanding Implied Volatility Inflation Before Results

As an earnings announcement approaches, implied volatility on that stock’s options typically rises, reflecting
the market’s anticipation of a larger-than-usual move — inflating option premiums for both calls and puts even
before the actual result is known, purely due to elevated uncertainty.

The IV Crush After Results Are Announced

Once results are announced and uncertainty resolves, implied volatility typically collapses sharply — an “IV
crush” that can significantly reduce option premiums even if the underlying moves in the direction a trader
correctly anticipated, sometimes resulting in a loss on an otherwise directionally correct trade.

Buying Options Ahead of Earnings: The Core Risk

Traders buying calls or puts specifically ahead of earnings need the stock to move enough to overcome both the
elevated premium paid and the subsequent IV crush — a considerably higher bar than simply predicting the correct
direction, which is why many earnings-related option purchases lose money even when the directional call proves
correct.

Selling Options Ahead of Earnings

Conversely, some traders sell options ahead of earnings specifically to capture the elevated premium and benefit
from the IV crush, betting that the actual move will be smaller than what’s priced in — a strategy that profits
from overestimated volatility but carries substantial risk if the actual move turns out to be genuinely large.

Straddles and Strangles Around Earnings

Volatility-based strategies like straddles and strangles are commonly used around earnings specifically because
they don’t require a directional view — but as discussed elsewhere, they still need to overcome both premium cost
and potential IV crush, making them a considered bet on movement magnitude rather than a guaranteed profit
opportunity around any earnings release.

Defined-Risk Strategies for Earnings Trades

Given the elevated uncertainty, many traders prefer defined-risk strategies like spreads over naked option
buying or selling around earnings specifically, since a spread’s capped risk limits the damage if the actual move
(or lack of one) works against the position.

Reviewing Historical Earnings Reactions

Studying how a specific stock has historically reacted to past earnings announcements — average move size,
whether it tends to gap and hold or gap and reverse — provides useful context for setting realistic expectations
about the current quarter’s likely reaction, though past reactions never guarantee future behaviour.

Position Sizing for Earnings-Related Trades

Because earnings-related moves carry genuinely elevated uncertainty, sizing positions more conservatively than
your typical non-earnings trade is a reasonable risk-management practice, given the binary, less predictable nature
of the outcome compared to a typical technically-driven setup.

A Final Word on Trading Earnings With Options

Earnings season offers genuine opportunity for options traders willing to understand the specific mechanics of
implied volatility inflation and crush — but it punishes traders who treat it like an ordinary trading day, ignoring
how these dynamics uniquely shape risk and reward around results.

Learning From Each Earnings Season

Keeping a specific record of how your earnings-related option trades performed, separate from your regular trading journal, helps build pattern recognition around which types of earnings setups tend to work for you and which consistently disappoint, given how distinct this trading environment is from ordinary sessions.

A Final Word on Trading Results Season

Earnings-related options trading rewards a genuinely different skill set — modelling implied volatility behaviour, not just predicting direction — that’s worth deliberately developing separately from your general options trading approach.
