You expect a big move but don't know which way. Buy volatility — a call AND a put together. If the underlying explodes in either direction, you profit. If it stays calm, you lose double premium. This chapter goes deep: IV crush mechanics, event entry timing, straddle-vs-strangle selection, adjustment recipes, and how to actually make money on this notoriously hard-to-profit-from trade.
Straddle costs more but wins on smaller moves. Strangle is cheaper but needs a bigger move.
Max loss = total premium paid (at the strike). Break-evens are strike ± total premium. Wings extend up-and-away infinitely on both sides.
Situations expecting a big move with uncertain direction:
Sensex at ₹80,000. RBI policy Friday. IV is elevated pre-event (India VIX 18 vs. baseline 13).
Setup:
Break-evens at expiry:
Need at least ~0.86% move in either direction to break even. Max loss ₹13,800 lands exactly at the strike. The market must exceed what’s already priced in.
Total cost = Call premium + Put premium (per share)
Upper break-even = Strike + Total cost per share Lower break-even = Strike − Total cost per share
Max loss = Total cost × Lot size (occurs if underlying = strike at expiry)
Max profit = Unlimited (upside), Large (downside, capped at strike × lot)
Required move to break even = Total cost per share ÷ Spot price
Same event setup, but use OTM strikes:
Break-evens:
Half the cost of the straddle, but profit zone is narrower on the outside. Needs bigger move to reach BE.
Sensex must exceed a ~1.06% move to profit. Straddle needed ~0.86%. Trade-off: cheaper trade, more directional threshold.
On event days, options are ALREADY priced for a big move — implied volatility (IV) is elevated. After the event, IV collapses (“IV crush”) even if the price moves.
If the actual move is smaller than what the market priced in, you lose money DESPITE being right about direction.
Sensex at 80,000 pre-RBI. Straddle costs ₹690/share (very rich; IV = 22%).
RBI announces; Sensex ends at 80,400 (+0.5%).
Post-event: IV crashes from 22% → 14% (normalization).
Post-event option values:
New position value: 410 + 20 = 430 × 20 = ₹8,600 Original cost: ₹13,800 Loss: −₹5,200 despite being right that Sensex would move slightly up
The market had priced a ~0.86% move; only 0.5% happened. IV crush killed the trade.
Rule 1: Enter 1-2 trading days BEFORE the event.
Rule 1: Exit IMMEDIATELY after the announcement.
Rule 2: NEVER hold past 15:15 IST on event day if trade is losing.
Rule 3: The IV crush window is 30 minutes to 24 hours post-event.
For an event straddle to be worth entering:
Without one of these, event straddles are negative EV. Traders often gamble on them for the thrill. Don’t be that trader.
Nifty range-bound for 2+ weeks, coiling. Buy a straddle when:
Historical example: Nifty in a 200-point range for 3 weeks. Buy a monthly straddle at 25,000 for ₹300 per side. IV = 11% (historical low). Any move above ~1.2% profits.
Individual stocks around earnings can be highly profitable IF:
Best candidates: mid-caps with wide earnings distributions.
After a huge market crash, IV spikes to 30-40. This is the WORST time to be long vol.
But 3-7 days after the initial shock, if the market stabilizes and IV is trending down but still elevated: short-vol setups work, not long-vol. Don’t confuse this.
Not for profit — for protection:
Use as portfolio hedge, not P&L strategy. Expected to lose most months; wins big on extreme events.
Symptom: 1 day into 5-day trade; Sensex jumped 1.5%; call up ₹300 (from ₹350), put worth ₹50.
Action A — Close entire position.
Action B — Close the winning leg only.
Action C — Roll winning leg further OTM.
Symptom: 2 days in; both legs worth ~40% of original.
Action A — Cut losses immediately.
Action B — Convert to strangle (widen exposure).
Symptom: Sensex moved 0.5% but IV crushed 8 points; straddle values dropped 40%.
Action: Close IMMEDIATELY.
Symptom: 1 day left; Sensex barely moved; both legs deep OTM.
Action: Close for whatever residual value remains.
For event trades, if it’s not working within 24 hours, close and move on.
Long vol trades that need extended time to work are usually wrong. Close them.
Advanced traders sometimes do the OPPOSITE — sell straddles/strangles pre-event to capture IV crush:
Long straddles are high-risk directional bets. Size like a call/put purchase, not like an income strategy.
Max risk per trade = 2% of account (as always) Max loss on straddle = Total premium paid × Lot size Max lots = Max risk ÷ Max loss per lot
Example: ₹5L account, 2% = ₹10K. Sensex straddle at ₹13,800/lot → max 0 lots (over budget).
Use a smaller strangle instead:
Long straddle/strangle trading returns are BINARY and lumpy:
Only professionals with real edge (news, research, specific setups) make sustained money on this strategy. Retail should treat it as gambling budget or hedging.
Any no → skip.
The long straddle is one of the hardest strategies to profit from consistently. Master its mechanics but expect most of your options income to come from other strategies (spreads, condors, covered calls).
