Put Backspread

They're opposites. A ratio put spread sells 2 puts and buys 1 (limited profit, unlimited risk). A put backspread buys 2 puts and sells 1 (substantial profit potential, limited risk). Ratio spreads are for collecting premium with a price floor thesis. Backspreads are for capturing large crashes with defined risk.

If price stays between your strikes (especially at the long strike), you'll lose money - potentially your maximum loss. However, if you entered for credit and price rises above your short strike, you keep the credit. Backspreads need big moves - small moves or stagnation at long strike is the worst outcome.

Credit entry provides a 'safety net.' If you're wrong and price goes up, you still keep the credit. It reduces your overall risk profile. If bearish thesis is correct and price crashes, you profit from the move. Credit entry means you profit in 2 of 3 scenarios (crash or rally), only losing if price stagnates at long strike.

Put backspreads have defined risk, so margin is typically the max loss amount. Since you're long more options than short, and the long puts cover the short put below the long strike, the position is fully hedged. It's much simpler margin-wise than ratio put spreads.

Two reasons: (1) They profit from falling prices, and (2) They're net long vega, so they benefit from IV increases. Crashes ALWAYS come with IV spikes. So put backspreads profit from BOTH effects simultaneously - unlike simply buying puts where you're fighting against high IV at entry.

Consider this when: (1) You've achieved good profit and want to lock some in, (2) Crash momentum is slowing, (3) IV is starting to crush and you want to reduce vega exposure, (4) You're approaching expiration and want to reduce gamma risk. Selling one long put converts substantial potential to defined profit but removes further downside participation.

At 21 DTE: If profitable, consider closing or converting. If at max loss zone, evaluate whether to close for salvage value or hold. At 7 DTE: Close unless positioned well below long strike. Theta accelerates dramatically and being at max loss zone with a week left is very difficult to recover from.

Roll if: Your bearish thesis is still valid but you need more time, and you can roll for minimal additional cost. Don't roll if: Thesis is broken (catalyst passed without expected move), or rolling significantly increases your max loss. Sometimes accepting the loss is better than extending a failing position.

You're net long vega, so IV increase helps significantly. During crashes, IV spikes - often 50-200%. This means your long puts gain additional value beyond just the price movement. Take profits on the combined delta and vega gains rather than waiting for perfect bottoms. After the crash, IV will normalize, taking back vega gains.

Wider spreads provide more leverage on severe crashes. For portfolio protection against 15-25% crashes, use wider spreads (150-250 points for STI) that become profitable during significant declines. Narrow spreads may hit max loss on moderate declines that don't provide meaningful portfolio offset.

In contango (back months higher IV), front month may be better - your short put IV is relatively higher, improving credit/reducing debit. In backwardation (front months higher), back months are better - your long puts are cheaper relative to front. For ongoing protection, consider back month backspreads rolled quarterly to capture term structure benefits.

Calculate desired protection level. Example: S$500,000 portfolio, want 50% protection on a 20% crash (protect S$50,000). A put backspread with max profit at 20% down needs to generate S$50,000 at that level. Work backwards from the payoff curve to determine contracts needed. Accept the max loss as 'insurance premium' cost.

Put backspreads: Direct exposure to underlying, benefit from both delta and vega, credit entry possible, defined risk. VIX calls: Pure volatility exposure, benefit only from vega/VIX spike, premium cost always, may not correlate perfectly with portfolio. Put backspreads are often more capital efficient and provide more direct hedge correlation.

1x3 provides more leverage on severe crashes but typically costs more (less credit or more debit) and has larger max loss. Use 1x3 when: protecting against extreme tail risk (20%+ crashes), willing to accept higher max loss for more protection. Stick with 1x2 for most situations - it provides good leverage with manageable risk.

Track: (1) Total cost (sum of max losses or debit entries), (2) Protection captured (profits during declines), (3) Portfolio performance with and without hedge. Calculate the 'insurance ratio' = crash profits / cumulative costs. Also measure the 'peace of mind' factor - did the hedge allow you to stay invested during volatile periods? A good hedge program should have positive net value over full market cycles.
