Dead Cat Bounce: Why You Shouldn't Catch a Falling Knife
Introduction
The term "falling knife" describes the attempts to buy an asset after a sharp decline. Attempting to catch such a "knife" often results in severe losses: a brief rebound ("dead cat bounce") does not signify a trend reversal. Understanding this phenomenon and implementing strict risk management strategies can help protect capital.
1. The Dead Cat Bounce Phenomenon and Its Characteristics
1.1 Definition
A dead cat bounce is a temporary price increase following a significant decline that does not change the overall market direction.
1.2 Buy to Cover and Stop Orders
This short-term rebound occurs due to covering short positions and the triggering of stop-loss orders.
1.3 Volume and Confirmation
A genuine reversal requires volumes above average; with a dead cat bounce, volumes quickly decrease.
1.4 Key Indicators
– The bounce occurs below a broken support level.
– RSI and Stochastic remain in extremes.
– Decrease in volume after the initial spike.
2. Dangers of Catching a Falling Knife
2.1 Unlimited Losses
The price continues to fall, and without a stop-loss, losses can become uncontrollable.
2.2 Stop-Losses Triggering
Temporary bounces trigger protective orders only to have the trend reinforce afterward.
2.3 Psychological Stress
Fear and stress lead to chaotic decisions and additional mistakes.
2.4 XYZ Example
XYZ shares fell from ₽150 to ₽50; buyers at ₽55 incurred a 27% loss.
3. Technical Tools for Identifying False Rebounds
3.1 Support Levels
A bounce below a support level is almost always false.
3.2 Retest
Holding price above broken support during a retest indicates a potential reversal.
3.3 RSI and Stochastic
RSI < 30 + volume > average → possible genuine bounce.
3.4 Volume Profile and VWAP
These tools highlight areas of most active trading that serve as price support.
4. Risk Management and Stop-Loss
4.1 ATR for Stop-Loss
ATR × 1.5–2 helps establish an adequate level of protection.
4.2 Trailing Stop
This follows price movements, securing profits during reversals.
4.3 Example
Buying at ₽100, ATR = ₽5, stop-loss at ₽92.5 — risk of 1% of the deposit.
5. Volume and Volatility
5.1 VIX and ATR
An increase in VIX > 30 and ATR above average warns of extreme movements.
5.2 Spike Volume
Volume spikes > 300% of the average over 5 minutes often accompany false rebounds.
5.3 Order Book Depth
Clusters of large orders indicate levels of interest and potential price support.
6. Trader Psychology and Emotional Traps
6.1 FOMO and Cognitive Distortions
"Fear of missing out" leads to hasty entries during temporary rebounds. The immediate desire to "keep up" with the movement triggers irrational decisions without thorough signal analysis.
6.2 Black-and-White Thinking and the Sunk Cost Fallacy
Traders tend to view trade outcomes in terms of "success/failure." This amplifies stress during initial losses and hampers effective strategy reassessment.
6.3 Perfectionism and Procrastination
The quest for the ideal entry delays decision-making, causing prices to continue falling to lower levels, thus increasing losses.
6.4 Practical Tips for Emotion Management
– Maintain a trading journal detailing emotional states.
– Use a "timeout" method: take a 2–5 minute pause before entering.
– Develop and automate an action plan based on clear entry/exit conditions.
6.5 Example of an Emotional Trap
Trader S, after a series of winning trades, entered on the "knife" without volume analysis. The hope of recovering recent losses intensified emotional pressure, leading to holding the position too long.
7. Fundamental Triggers
7.1 Corporate News
Reports and news about crises may trigger a dead cat bounce on rumors of support from investors.
7.2 Macroeconomic Background
Changes in interest rates, sanctions, or geopolitical events can trigger a series of false rebounds before a long-term decline.
7.3 News-Driven Example
In 2021, shares of the metallurgical company UPQ rose 10% on speculation about a merger, but a week later, shareholders received no confirmation, and the price fell 30%.
8. Automation for Protection
8.1 Volume Algorithms
Scripts react to spike volumes and automatically set trailing stops to secure profits.
8.2 API Integration
Instant stop-loss placement reduces the risk of missing execution due to human delays.
8.3 Robot E: Case Study
The robot analyzes volumes and the order book, placing limit orders and consistently yielding 3–5% monthly with minimal volatility in strategy.
9. Regional Characteristics
9.1 "Polyus" Example
A gap from ₽21,500 to ₽24,000 and subsequent retracement without filling the gap demonstrated that local assets on MOEX are especially sensitive to news spikes.
9.2 Depth of the Russian Order Book
Limited order book depth and small free float amplify the amplitude of false rebounds.
9.3 Characteristics of Russian Options
Rare expiration dates and low liquidity complicate hedging and protection against declines using derivatives.
10. Real Cases of Knife Catching
10.1 Biotech Crash (2020)
BiomedTech dropped from $120 to $30 due to clinical trial failures. Entry at $35 resulted in a -40% loss in a day.
10.2 Oil Flash Crash (2020)
WTI fell below $0, with an entry at $1 proving fatal due to a chain of margin calls at -$37.
10.3 Crypto Dip (2022)
Bitcoin: from $45,000 to $20,000; entry at $25,000 led to a drop to $16,000 and multiple liquidations.
11. Averaging Strategies and Alternatives
11.1 Dangers of DCA
Averaging lowers the average entry price, but during a continued decline, it increases overall loss.
11.2 Alternative Methods
– Partially closing the position at the first rebound.
– Using options for hedging.
– Waiting for a retest while placing limit orders.
11.3 Averaging Example
Trader F averaged the stock from ₽100 to ₽50; the price fell to ₽20, resulting in an overall loss of 80%.
