What is a bear market?
– A bear market is a prolonged period in which prices across a financial market fall significantly and investor sentiment turns broadly negative. A commonly used rule of thumb is a decline of 20% or more from a recent high, sustained over time. That 20% threshold is practical rather than scientific — it’s an arbitrary cutoff used by market watchers.
Why prices fall
– Share prices reflect expectations about future company performance. If earnings or growth fall short of expectations, investors sell; if many investors sell at once, prices can spiral lower. Herd behavior and fear amplify declines. External shocks (economic slowdowns, bubbles bursting, pandemics, wars, big policy shifts) and policy changes (tax or interest-rate moves) can trigger or deepen bear markets.
Bear markets vs. corrections
– Correction: a shorter, shallower decline (commonly defined as a drop of about 10%) and usually lasts fewer than two months.
– Bear market: a deeper, longer decline (benchmark ~20% or more) and often coincides with weaker economic fundamentals. Because it’s difficult to identify the low in real time, bear markets rarely provide obvious, low-risk entry points for buyers.
Types of bear markets
– Secular bear market: a long-lasting period (often measured in years, sometimes a decade or two) of below-average returns, though intermittent rallies can occur.
– Cyclical bear market: a shorter episode (weeks to months) often tied to the economic cycle.
Typical causes and early signs
– Causes: slowing economy, bursting asset bubbles, major geopolitical or health crises, structural economic shifts, and policy tightening.
– Early signs: falling corporate profits, lower trading volumes, deteriorating economic indicators, rising pessimism among investors, and policy shifts that reduce liquidity or demand.
Four phases of a bear market
1) Late-bull / distribution: Prices are still high and investor optimism is common. Near the end of this phase, profit-taking rises and some participants reduce exposure.
2) Panic / sharp decline: Prices fall rapidly. Trading activity and corporate profits weaken. Investor fear accelerates selling — this stage often includes “capitulation,” where many investors give up and sell.
3) Short-covering and speculative bounce: After steep declines, speculators and bargain hunters re-enter, producing temporary rallies and higher volume.
4) Gradual stabilization and recovery: Prices drift lower or sideways but begin to attract longer-term investors as valuations, and sometimes good news, improve. Over time this can transition into a new bull market.
Short selling, puts, and inverse ETFs (basic notes)
– Short selling: borrowing shares to sell now with the obligation to buy back later. Profit if price falls; loss if price rises. Risk is theoretically unlimited if shares rally.
– Put option: a contract that gives the holder the right (but not the obligation) to sell a security at a set price before expiration. Puts can limit downside exposure but cost a premium.
– Inverse ETF: an exchange-traded fund designed to gain when an index falls. Many are meant for short-term trading and can diverge from expected returns over longer holding periods.
– Caution: these are hedging or speculative tools. They have distinct mechanics, timing issues, costs, and risks. They are not substitutes for a coherent allocation plan.
Real-world examples (brief)
– 2007–2009 financial crisis: a prolonged bear market that wiped out roughly half of the S&P 500’s value over about 17 months.
– March 2020 (pandemic shock): major U
.S. and global equity markets plunged in March 2020, producing one of the fastest bear-market declines on record before a sharp, stimulus-fueled recovery. That episode highlights two features of bear markets: speed (how fast prices fall) and depth (how far they fall). Below are practical ways to measure, respond to, and learn from bear markets.
How to tell if you’re in a bear market (quick diagnostic)
– Official threshold: a decline of 20% or more from a recent peak is the conventional definition of a bear market (20% is a rule of thumb used by market commentators). Source: historical market practice.
– Confirm with drawdown calculation (drawdown measures loss from peak to trough): Drawdown % = (Trough price − Peak price) / Peak price × 100. Example: Peak 4,000 → Trough 3,000 → Drawdown = (3,000 − 4,000)/4,000 = −25% (a 25% decline).
– Check breadth and volatility: poor market breadth (few stocks leading declines) and rising implied volatility (e.g., VIX) make bear conditions more likely to be sustained.
– Economic indicators: rising unemployment, contracting GDP, and yield-curve inversion often coincide with broader sell-offs but are not definitive triggers on their own.
Simple step-by-step: compute your portfolio drawdown
1. Identify the peak portfolio value before the decline (date and amount).
2. Identify the lowest portfolio value after that peak (trough).
3. Apply formula: Drawdown % = (Trough − Peak) / Peak × 100.
Example: Peak $120,000 → Trough $84,000 → Drawdown = (84,000 − 120,000)/120,000 = −30%.
Checklist for retail traders during a bear market (practical, non-prescriptive)
– Stop and inventory: list holdings, sizes, basis (purchase prices), and liquidity.
– Revisit your investment plan: confirm time horizon and risk tolerance; if these haven’t changed, avoid making decisions based on fear.
– Consider rebalancing: if target allocation is 60% equities / 40% bonds, a large equity drop will create underweight in equities — rebalancing involves buying equities and selling bonds to return to targets. See the worked example below.
– Use cash strategically: preserve liquidity for living expenses and margin requirements; avoid forced selling in tax-inefficient ways.
– Avoid knee-jerk leverage: adding margin during high volatility can result in forced liquidations.
– Consider measured hedges (if you understand costs): protective puts, short-duration inverse ETFs, or options spreads — but recognize premiums and tracking errors.
– Tax-loss harvesting: realize losses in taxable accounts to offset gains, but be mindful of wash-sale rules.
– Keep a watchlist: identify quality names you’d consider buying with pre-set criteria (valuation, balance sheet, business model).
Worked examples
1) Rebalancing example (numeric)
– Starting allocation: $100,000 total; 60% equities = $60,000; 40% bonds = $40,000.
– Equities fall 30% → new equities = $42,000; bonds unchanged = $40,000; portfolio = $82,000.
– Target 60/40: equities should be 0.60 × $82,000 = $49,200; bonds 32,800.
– Action to rebalance: buy $7,200 of equities and sell $7,200 of bonds (if allowed), or add fresh cash to equities if you prefer not to sell bonds.
2) Protective put cost illustration (ETF example)
– ETF price (e.g., SPY) = $400. You buy one put option with strike $360 (10% out-of-the-money) costing $5 premium per share-equivalent (options are quoted per share-equivalent; one contract = 100 shares).
– Premium cost per ETF share = $5 → 1.25% of $400.
– If ETF falls to $300 at expiration, the put (strike 360) is worth $60 → net payoff per share = $60 − $5 = $55 protection (you’ve limited downside below the strike at the premium cost).
– Trade-off: you pay the premium whether the market falls or not; repeating puts each period raises costs.
3) Stop-loss example
– Buy 100 shares at $50. A 15% stop-loss would be at $42.50. If price hits $42.50, your shares are sold.
– Pros: limits downside without option costs. Cons: can trigger on temporary volatility (whipsaw) and lock in losses.
Practical hedging checklist (if you choose
to hedge):
Practical hedging checklist
– Define the objective. Decide whether you want full protection (limit all downside), partial protection (limit some percentage), or tactical protection (short-term around events). Be explicit: e.g., “protect 50% of my ETF position for 3 months” or “limit losses to 20% on this holding.”
– Inventory the exposure. Calculate current position size in shares and dollars. Formula: position value = shares × current price.
– Choose instrument and horizon. Common choices: puts (right to sell), collars (buy put + sell call), or stop-loss orders. Match option expiration to the period you want protection for; shorter expirations cost less but require more frequent rollovers.
– Size the hedge. For plain-vanilla puts:
– Contracts required = shares / (contract size). Most equity option contracts = 100 shares per contract.
– If using delta (option sensitivity to price): contracts = shares / (|delta| × 100). Example: owning 200 shares and using a put with delta = −0.50 → contracts = 200 / (0.5 × 100) = 4 contracts.
– Check costs and breakeven. Record total premium paid, commissions, and fees. Annualize cost if you plan repeated hedges: annualized premium ≈ (premium / protection period in years). Compare to downside you’re willing to pay to avoid.
– Consider a collar to reduce premium. Example worked example:
– You own 200 shares at $400.
– Buy 2 put contracts (strike $360) costing $5.00 per share → cost = 2 × 100 × $5 = $1,000.
– Sell 2 call contracts (strike $440) receiving $3.00 per share → credit = 2 × 100 × $3 = $600.
– Net premium paid = $1,000 − $600 = $400 (effectively $2 per share). This narrows upside above $440 but reduces the out-of-pocket cost of protection.
– Understand order types and execution risk. With stop-losses choose between:
– Stop-market (becomes market order at trigger — execution guaranteed but price uncertain).
– Stop-limit (becomes limit order — price controlled but execution not guaranteed).
Account for slippage, especially in fast moves.
– Monitor implied volatility (IV). Higher IV → higher option premiums. If IV spikes before expiration (e.g., around earnings), option cost increases; consider buying earlier or using collars to offset.
– Plan for rolling or closing. If protection expires and you still want it, plan the roll: close current option and open a later-dated one. Record realized P/L from the hedge to evaluate whether it was worthwhile.
– Tax and margin considerations. Options sales or exercise can create taxable events. Short options may require margin; check with your broker.
– Liquidity and bid-ask spreads. Prefer options with sufficient open interest and tight spreads to reduce execution cost.
– Keep a written rule set. Example: “If a holding drops X% and hedge cost > Y% of portfolio, reassess rather than auto-roll.”
Worked numeric sizing example
– You hold 300 shares of ETF at $150 → position value = 300 × $150 = $45,000.
– Standard option contract = 100 shares → base contracts needed to fully cover = 300 / 100 = 3 contracts.
– If you instead choose puts with delta −0.40: contracts = 300 / (0.4 × 100) = 7.5 → round to 8 contracts for near-full delta coverage (this creates slight over-hedge).
– If put premium = $6 per share, cost for 8 contracts = 8 × 100 × $6 = $4,800. Annualize if this protects 3 months: annualized cost ≈ $4,800 × (12/3) = $19,200 (shows high cost of repeatedly buying short-dated puts).
Practical limitations and behavior checklist
– Accept friction: hedging reduces volatility but usually reduces expected returns net of cost.
– Avoid
– Avoid over-hedging: using more option exposure than your delta-implied need creates a persistent short directional bias (you pay for protection and also constrain upside). Round contract counts conservatively and be explicit about any intentional over- or under-hedge.
– Avoid timing the market: trying to buy protection only when fear spikes usually means paying very high implied volatility; consider a rule-based schedule (calendar, volatility trigger) rather than discretionary timing.
– Avoid ignoring option Greeks other than delta: theta (time decay) and vega (sensitivity to implied volatility) materially affect cost and behavior of the hedge. Short-dated puts have large theta; long-dated puts have larger vega risk.
– Avoid liquidity traps: thinly traded strikes and expirations widen bid-ask spreads and increase execution cost—use liquid strikes (at-the-money and standard monthly expirations) when possible.
– Avoid operational complexity without governance: document hedge intent, rules for sizing/rolling, and who executes. Frequent ad hoc hedging increases transaction costs and error risk.
– Avoid forgetting assignment and early exercise risk (for American-style options): short options can be assigned early around dividends or close-to-expiration intrinsic value—account for this operationally.
– Avoid tax and accounting surprises: option gains, losses, and wash-sale rules can create tax effects different from underlying securities; consult a tax professional for specifics.
Quick decision checklist before implementing a hedge
1. Define the objective: protection against a drop (downside insurance), volatility reduction, or liability matching? Be explicit about maximum tolerable loss and acceptable capped upside.
2. Determine horizon: how long do you need protection? Match option expiration or plan for rolling.
3. Measure exposure: compute notional and delta-equivalent contracts (contracts = shares / (|delta| × 100)). Round consciously.
4. Compare instruments: puts, collars (buy put + sell call), protective stop orders, inverse ETFs, or futures—evaluate cost, liquidity, and operational burden.
5. Model costs: include premium, commissions, bid-ask spread, and expected roll costs (if hedges will be renewed). Annualize for comparison.
6. Set entry and exit rules: when to close/roll, when to let protection lapse, and under what market conditions you will adjust.
7. Monitor and review: track performance vs. objective and document lessons.
Worked numeric example — protective collar to reduce cost
Assume the same portfolio value of $45,000 (300 shares × $150). You want 3-month downside protection but want to reduce premium outlay by capping some upside.
– Buy 8 put contracts (delta ≈ −0.40) at $6.00 premium per share → cost = 8 × 100 × $6 = $4,800 (this is the earlier full-put cost example).
– To offset premium, sell 3 covered-call contracts at a higher strike that pays $1.50 premium per share → proceeds = 3 × 100 × $1.50 = $450.
– Net cost this quarter = $4,800 − $450 = $4,350. If you wanted near-neutral cash flow you could increase calls (but that caps upside on those shares).
Notes on this example: selling fewer calls than puts still leaves a net cost but reduces it; selling more calls to fully offset cost increases the chance of assignment and caps upside. Always check strike selection relative to your return objective.
Monitoring and rolling rules (practical guide)
– Predefine roll triggers: e.g., if put is up X% (profitable) or underlying moves Y% against you, roll to a later expiration or different strike.
– Evaluate roll cost: compare remaining time value on current option vs. premium for new option; rolling often crystallizes a realized loss/cost.
– Watch implied volatility: if IV has fallen after you bought puts, their market value shrinks even if realized volatility remains low—deciding to hold vs. roll depends on your forecast for future IV and direction.
Alternatives and complements to buying puts
– Protective stop orders: simple and cheap but can be triggered by intraday volatility and do not guarantee execution price.
– Inverse ETFs: provide directional downside exposure without options complexities but can suffer from tracking error and daily reset issues.
– Futures/shorting: efficient for large portfolios but introduce margin, potential unlimited loss (if short), and require active management.
– Diversification and cash allocation: non-derivative ways to reduce portfolio volatility that avoid option premium decay.
Record-keeping and review
– Keep an “insurance log”: why the hedge was entered, sizing rationale, costs, and the rule that will terminate it.
– Post-mortem after market stress: evaluate whether hedge behaved as expected, total cost vs. benefit, and whether behavioral biases influenced timing.

Appendix — quick hedging checklist
– Define objective: downside protection, limit drawdown, lock in gains, or reduce volatility. Be specific (e.g., “limit 1-month downside to −10%”).
– Size the hedge: express as percent of portfolio or number of shares. For option hedges, 1 equity option contract typically covers 100 shares.
– Choose instrument & tenor: protective puts, collars, inverse ETFs, or variance swaps. Match hedge expiry to the risk window you care about.
– Cost vs. benefit: compute maximum cost (premiums paid), potential offsets (premiums received), and worst-case outcomes.
– Execution rules: entry signals, rebalancing frequency, stop / roll rules, and exit triggers.
– Record keeping: keep trade rationale, strike/expiry, premium, notional hedged, and termination rule.
– Post-event review: did the hedge behave as expected? Calculate realized cost per unit of protection.
