Definition
A dead cat bounce is a brief, temporary uptick in the price of a security or market inside a longer-term downtrend. Traders often see the move as a short-lived recovery that is subsequently followed by further declines. The term conveys the idea that a sufficiently large fall can produce a small rebound that does not change the overall downward trend.
Why it matters
Recognizing whether an uptick is a true trend reversal (a lasting change from downtrend to uptrend) or a dead cat bounce (a short interruption of the downtrend) matters for position sizing, risk management, and timing trades. Misreading a dead cat bounce as a durable bottom can lead to significant losses.
How analysts view it
Technical analysts classify a dead cat bounce as a continuation pattern: an apparent rally that fails to reverse the prevailing downward trend. A useful rule of thumb used by many analysts is that if price moves back below its prior low after a bounce, the bounce likely was temporary rather than a reversal.
Common causes
– Short-covering: traders who had bet on further declines buy back shares, driving a temporary price rise.
– Bottom-fishing: investors assume the asset is oversold and buy, producing a short rally.
– Noise: temporary optimism, stimulus headlines, or technical factors cause a pause in selling without a change in fundamentals.
Duration
Typically short — often days, sometimes weeks or a few months. Because it’s short-lived, many dead cat bounces are only clearly identified after the price resumes its decline.
Opposite pattern
An inverted dead cat bounce is a sharp, short-lived sell-off inside a longer-term bull market. It mirrors the same idea but in reverse.
Practical checklist to evaluate an apparent bounce
Use this checklist to structure your
analysis of an apparent bounce:
1) Define the time frame and trend context
– Decide whether you are analyzing intraday, daily, weekly, or monthly action. A pattern that is a dead cat bounce on a daily chart may be insignificant on a weekly chart.
– Confirm the prevailing trend: a dead cat bounce is, by definition, a short rally inside a longer-term downtrend. Check for a series of lower highs and lower lows on the chosen time frame.
2) Volume behavior (key tell)
– Compare volume on the decline, on the bounce, and on any subsequent moves. A classic dead cat bounce has heavy selling volume into the low and lighter volume on the bounce.
– Practical threshold: if selling volume on the drop > 1.5–2× average daily volume while the bounce occurs on < average volume, treat the bounce with skepticism.
3) Magnitude of the rebound (use retracements)
– Measure the bounce as a percent retracement of the preceding fall. Example: price fell from $100 to $40 (60% decline). A bounce to $55 is a 15-point rise = 37.5% retracement of the fall.
– Rule of thumb: shallow to moderate retracements (e.g., 20–50%) after a sharp multi-week/month decline are common and can be dead cat bounces. Sustained recoveries that exceed 50–61.8% Fibonacci levels and are accompanied by improving breadth may indicate a real reversal.
4) Momentum and technical indicators
– Check momentum indicators (RSI, MACD). A bounce that fails to push RSI above neutral (e.g., 50) or that shows bearish divergence (price up, indicator lower) suggests weakness.
– Look for moving-average behavior: a bounce that stalls below key moving averages (50-day, 200-day) often lacks conviction.
5) News and fundamentals
– Search for news catalysts: earnings, regulatory announcements, macro headlines. A bounce driven only by technical short-covering or vague optimism, without improving fundamentals or credible catalysts, is more likely temporary.
– Check earnings guidance, revenue trends, cashflow, leverage and any adverse material developments. Fundamental deterioration undermines the case for a sustainable rebound.
6) Short interest and covering dynamics
– Short interest (shares sold short / float) and recent changes matter. High short interest can fuel a sharp but short-lived short-covering rally.
– Confirm whether the bounce coincides with declining short interest or reported short-covering days to cover. Short-covering rallies often occur on a few concentrated days.
7) Market and sector breadth
– Compare the asset’s move to the broader market and its sector. A lone stock rally while its sector and market remain weak raises caution.
– Use breadth measures (advance/decline lines, sector ETFs) to judge whether the bounce is idiosyncratic or part of broader recovery.
8) Options and volatility signals
– Rising implied volatility while price rises can indicate hedging by shorts or continued fear. A genuine recovery typically sees implied volatility decline as risk premiums shrink.
– Watch put/call ratios and option flow for unusual buying/selling that may be transient.
9) Confirmatory tests (wait for follow-through)
– A pragmatic approach: require a follow-through over a defined period (e.g., close above the recent swing high on increased volume within 5–10 trading days) before assuming a trend change.
– Set clear criteria beforehand so you avoid hindsight bias.
Worked numeric example
– Scenario: Stock falls from $120 to $48 (60% decline). Average daily volume before the drop = 1.2M shares. During the drop, volume spikes to 3.0M. The stock rebounds to $66 over 6 trading days (a 37.5% retracement).
– Observations:
– Bounce volume averages 0.8M (below prior average).
– RSI moves from 18 to 38 (still below neutral).
– Price remains below 50-day MA and below the prior support-turned-resistance at $75.
– No positive fundamental news; short interest remains high.
– Conclusion: indicators point toward a likely dead cat bounce. Appropriate reaction is caution and waiting for confirmatory price/volume action rather than assuming recovery.
Quick decision checklist (what you can do next)
– Gather: chart (multiple time frames), volume history, short interest, recent news, sector/market context.
– Apply rules: bounce volume vs decline volume; retracement %; indicator confirmation; moving-average behavior.
– Define plan: if you are a trader, set entry triggers, stop-loss, and target using measured risk; if you are a longer-term investor, require fundamental improvement before adding exposure.
– Monitor: re-evaluate after 3–10 trading days or after a target threshold is reached.
Limitations and common pitfalls
– Identification is often retrospective: a bounce may only be labeled a dead cat bounce after the price resumes decline.
– Overreliance on a single indicator (e.g., volume alone) is risky. Use converging evidence.
– Time frame mismatch: a short-lived bounce for one trader could be a material move for another depending on horizon.
