Frequently Asked Questions

Why would I use a bear put spread instead of just buying a put?

A bear put spread costs less than a single put because the short put reduces your net debit. This lowers your breakeven point and defines your maximum risk. However, your profit is capped at the spread width. Use it when you're moderately bearish and want to reduce cost basis.

What happens if the stock price rises instead of falling?

If the underlying rises above your higher strike at expiration, both options expire worthless and you lose the entire net debit paid. This is your maximum loss and it's known upfront when you enter the trade - unlike short selling where losses are unlimited.

Can I close a bear put spread early?

Yes, you can close the spread at any time before expiration by selling the long put and buying back the short put. Many traders close at 50% of max profit to lock in gains and free up capital for new trades.

How is a bear put spread better than short selling?

Bear put spreads have defined, limited risk (only the debit paid), no borrowing costs, no locate requirements, no dividend liability, and no risk of short squeezes. Short selling has unlimited loss potential and various costs and restrictions.

What's the minimum capital needed to trade bear put spreads in Australia?

Since bear put spreads are debit strategies, you only need enough capital to pay the net premium. A typical spread might cost A$150-A$400 per contract. However, most brokers require minimum account sizes of A$1,000-A$5,000 for options approval.

How do I choose between a bear put spread and a bear call spread?

Both are bearish strategies with similar payoffs, but bear put spreads (debit) work best in low IV environments, while bear call spreads (credit) are preferred in high IV. Also consider: debit spreads have no assignment risk on the short leg until very deep ITM, while credit spreads require margin.

How does volatility expansion during market declines affect my bear put spread?

This is actually a double benefit! Bear put spreads are net long vega, so when IV rises (as it typically does during selloffs), your spread gains value from both the directional move AND the volatility expansion. This is why bear put spreads can be more profitable than expected during market corrections.

Should I time my bear put spread around ex-dividend dates?

Yes, this can work in your favor. Stocks drop by approximately the dividend amount on ex-dividend date. Entering a bear put spread just before ex-dividend captures this drop. However, this is partially priced into options, so the edge is small.

What's the optimal time to expiration for bear put spreads?

21-45 DTE typically offers the best balance. Shorter durations have higher theta decay risk, while longer durations pay more time premium. For specific catalysts like earnings or announcements, choose the first expiry after the expected event.

How do I roll a bear put spread when it's profitable?

If you want to extend your bearish position: 1) Close the current spread for profit, 2) Open a new spread with same structure but later expiry and strikes adjusted to current price. Alternatively, just roll the short put to a lower strike while keeping the long put.

How can I use bear put spreads as portfolio hedges rather than directional trades?

Calculate your portfolio's beta-weighted delta to XJO. Then determine what percentage hedge you want (e.g., 30% of downside risk). Size your XJO bear put spreads to provide that delta offset. The spread's defined risk makes it a cost-efficient hedge versus long puts alone.

What's the optimal approach for exploiting put skew with bear put spreads?

Analyze the volatility skew across put strikes. OTM puts typically have higher IV than ATM puts in Australia. Sell the expensive OTM put and buy the fairly-priced ATM put. This 'skew harvest' improves your expected return. Use skew charts to identify optimal strike combinations.

How do I incorporate term structure analysis into bear put spread timing?

In contango (near-term IV lower than far-term), use shorter expirations as they're relatively cheaper. In backwardation (near-term IV higher), consider longer expirations. Backwardation often signals stress - ideal for initiating bear put spreads on broader market before the situation deteriorates further.

What quantitative metrics should I track for systematic bear put spread trading?

Track: win rate, profit factor, average win/loss ratio, max drawdown, Sharpe ratio, and expected value per trade. Also monitor: IV rank at entry, actual vs expected move, vega contribution to P&L, and slippage impact. Compare performance across different market regimes (trending vs ranging, low vol vs high vol).

How do I hedge tail risk on a portfolio of bear put spreads?

The irony is bear put spreads ARE often the hedge, but if you have concentrated bearish exposure and worry about a squeeze: 1) Add OTM call spreads as upside hedge, 2) Diversify across uncorrelated underlyings, 3) Keep position sizes small relative to portfolio, 4) Maintain cash reserves for adjustment.
