IV — THE PRICE TAG

Lesson 41 of 72 · 3 min read · Beginner · Updated Oct 21, 2026
STAGE 6 — Options II: Pricing, The Greeks, IV · Prerequisite: THETA & DTE — TIME IS BLEEDING
TL;DR
  • IV is the price tag on an option — what you're really paying for.
  • It inflates before big events and collapses in minutes after them (the crush).
  • The stock can go up and your call can still lose. Check IV against its recent range first.

What you're really paying for. The crush that eats earnings plays. IV is the price tag the market sticks on uncertainty. Before a big event, the tag gets marked up. The moment the event passes, the tag gets slashed — even if the stock moved your way.

THE TAKEAWAYS

  • Before a big event IV inflates — options get expensive. After, it collapses in minutes.
  • The stock can go UP and your call can still LOSE: the crush outruns the move.
  • Check IV against its own recent range before you buy. Cheap IV = wind at your back.
RUSTY’S RULE
Never buy the week of a big event without checking IV first.

WORKED EXAMPLE — STEP BY STEP

  1. A big report lands tomorrow. Today, IV inflates — every SPY option costs more than it did last week.
  2. You buy a call anyway. The report hits and SPY rises — the direction you wanted.
  3. Minutes later, IV collapses. The premium you overpaid evaporates faster than the move can pay you back.
HOW THIS TRADE LOSES

That's the crush, and it IS the losing variant: right stock, right direction, losing trade — because the price tag, not the chart, was the problem.

WHAT TIME & IV DO TO IT

The crush is fast: IV can collapse in minutes once the news is out. Time adds pressure too — the event premium you overpaid also bleeds away as theta does its daily work.

COMMON BEGINNER MISTAKES

  • Buying the morning of a big event without checking IV.
  • Assuming right direction = winning trade (the crush doesn't care).
  • Paying inflated IV for an expected move smaller than what the premium already expects.

CHECK YOURSELF

Q1. Before a big event, IV usually…

Q2. The stock rises after the event but your call still loses. What happened?

Q3. Before buying, the lesson says to check IV against…

DO IT ON PAPER

In Robinhood, open a SPY option and note its IV today. After the next big report day, check the same option's IV again and compare. Log both numbers in your journal.
