Earnings Crush Opportunity

Overview

This pillar analyzes the historical drop in a stock's implied volatility (IV) after an earnings report. It identifies opportunities where pre-earnings IV is excessively high, making short-volatility options strategies particularly profitable.

What It Does

The pillar calculates the average percentage that a stock's IV has 'crushed' or fallen in the 24 hours following its last 8 to 12 earnings announcements. It then compares this historical average to the current pre-earnings IV level. A significant gap suggests the market is overpricing uncertainty, creating a quantifiable trading edge.

Why It Matters

While most traders know IV drops after earnings, this pillar quantifies the expected magnitude of the drop. This allows you to precisely identify which options are most overvalued and offers a data-driven basis for constructing high-probability short-vega trades like straddles or iron condors.

How It Works

First, we collect historical IV data for a specific stock, focusing on the closing IV before earnings and the closing IV one day after. Next, we calculate the median percentage drop across the last 8-12 quarters to establish a baseline 'crush' expectation. Finally, this baseline is compared against the current IV to generate an 'Opportunity Score' that highlights inflated premiums.

Methodology

The core metric is the Historical Crush Percentage (HCP), calculated as the median of `(Pre-Earnings IV - Post-Earnings IV) / Pre-Earnings IV` over the last 8 quarters. The Opportunity Score is `(Current Pre-Earnings IV - Historical Post-Earnings IV Floor) / HCP`. A score greater than 1.2 suggests a statistically significant opportunity.

Edge & Advantage

This pillar provides an edge by transforming a well-known market tendency into a precise, actionable signal, allowing you to systematically target the most overpriced options.
