Long Straddle

Both options in a straddle have time decay (theta). Every day that passes, both the call and put lose value. If the stock doesn't move enough to offset this decay, you lose money. This is why straddles need significant movement to be profitable.

ATM strikes are standard because they have the highest gamma and are delta-neutral. However, if you have a slight directional bias, you could use slightly ITM options on the side you favor. Most traders stick with true ATM for pure volatility plays.

Compare IV Rank (current IV vs past year) and the implied move (straddle price / stock price) to historical moves around similar events. If IV Rank is low and historical moves exceed implied move, the straddle is relatively cheap.

If the stock closes exactly at the strike, both options expire worthless and you lose the entire premium. If the stock closes above the upper breakeven, your call has value. If below the lower breakeven, your put has value. One option will be exercised/assigned if ITM.

No. The maximum loss on a long straddle is the total premium paid for both options. This occurs when the underlying closes exactly at the strike price at expiration. Your risk is completely defined upfront.

A straddle uses the same strike for both call and put (typically ATM). A strangle uses different OTM strikes (e.g., OTM call and OTM put). Straddles cost more but have narrower breakevens. Strangles cost less but need larger moves to profit.

IV crush is the rapid drop in implied volatility after uncertainty resolves. The best approach is to close your straddle within 1-2 days after the event, capturing any directional gain before IV crush erodes profits. Don't hold hoping for more movement.

Leg out when you have a strong directional move and want to lock in profits on one side. For example, if the stock drops 8% after earnings, sell your profitable put and keep the call for a potential bounce. You've secured gains and have a free lottery ticket on the remaining leg.

Positive gamma means your delta moves in your favor as the stock moves. Starting with zero delta, a rally increases your delta (more call exposure) while a decline decreases it (more put exposure). This accelerates your profits during large moves - you effectively 'get longer' into rallies and 'get shorter' into declines.

Straddles are ideal when you expect a big move but have no edge in predicting direction - common before binary events. Rather than having a 50% chance of being right directionally, you have a chance of profiting regardless of direction, as long as the move is large enough.

Extract event volatility by comparing near-term (event) IV to post-event IV or non-event period IV. Event variance = Event expiry variance - Non-event variance. If your calculated single-day event variance is less than historical event variance, the straddle is underpricing the event.

Balance transaction costs against gamma capture. Scalp when delta reaches ±0.30 to ±0.50, or when P&L on the hedge would cover round-trip costs plus a reasonable profit. In practice, 2-4 scalps per day on volatile stocks can be effective. Less frequent in range-bound conditions.

Balance long straddles (positive vega) with short premium positions (negative vega) so aggregate vega is near zero. This isolates gamma and directional exposure from overall volatility exposure. Track portfolio vega daily and adjust as positions decay or move.

At minimum, your expected value per trade should exceed 5% of premium to overcome transaction costs and occasional outsized losses. With 60% win rate, you need avg win of at least 1.5x avg loss. Backtest with realistic slippage (typically 1-2% of premium per side).

Select underlyings with low correlation in their idiosyncratic moves. While earnings may cluster, individual stock reactions are often uncorrelated. Avoid multiple straddles in same sector (all banks, all miners) as they may move together. Diversify across sectors with different catalysts and IV cycles.
