Conclusion
P.S.
This article stems from a personal curiosity: I dedicated over a month to developing and refining the logic for post-analysis of five years of stock data to validate the 4% momentum burst setup. The goal? To understand how often stocks continue moving after breaking out with a 4%+ daily gain and what are pre and post behaviours.
The results? Honestly, it’s freaking amazing how consistently it works.
1. What is Momentum Burst and why 4% is the exact percentage.
Stocks move in momentum bursts of 3 to 5 days. During this 3 to 5 days period stock would go up 8 to 20% ( lower priced stock can even have bursts of up to 40%). Higher priced stocks above 40 tend to move in momentum bursts of 5 to 25 dollars.
Such bursts may or may not have clear identifiable catalyst. You need to know nothing about the company to trade this kind of burst. This is a pattern and probability based trade.
All such momentum bursts start with a range expansion. The first day of the move is range expansion day. Often there is also volume expansion along with range expansion.
The price moves in the direction of range expansion. When there is range expansion it attracts breakout traders, it attracts other momentum players, day traders, quants and so on. That results in continuation of move for few days.
Range expansion basically means a day which is up bigger than last 5 to 10 days bars. A range expansion preceded by series of range contraction days is good candidate in this setup. Moves preceded by orderly range contraction can be explosive.
A successful momentum burst will lead to immediate follow through. Say a stock breaks out in the morning, it will continue to go up through the day and will have immediate follow through in next 2 to 3 days. And the follow through should also be of big 4 to 5% plus magnitude on second or third day.
Momentum burst kind of swing trading allows you to grow your account with very low risk. For a mere 3 to 5 day exposure to market you capture the most explosive part of the move and you are not seating in dead periods holding stock waiting or anticipating a breakout which may or may not come.
Trading this kind of setup requires extremely good ability to ruthlessly cut losses if a trade does not work immediately . It also requires skill to exit when things are still in explosive phase and not wait for reversal.
Per trade profit on these kind of trades will be on an average just 5 to 10% as you are only going to get part of the 8 to 20% move. By the time you enter on breakout day the stock might be up 4 to 10% , so you will not be able to capture that part of the range expansion move.
To trade this kind of setup you need to be willing to do 200 to 1000 or more trades in a year. You make money by compounding these small gains. So this is high frequency and low per trade profitability method. But for a skilled trader this can lead to explosive returns.
Why 4% and not 5% or 6%?
According to Pradeep Bonde (aka Stockbee), a study conducted with a colleague from a major financial institution found that a 4% daily price move was the optimal threshold to identify short-term momentum breakouts—typically yielding sharp gains over the next 3 to 5 days.
Stocks don't move linearly; momentum comes in bursts. A stock that gains 150% in a year doesn't rise steadily—instead, it surges 10–20% in a few days, then consolidates for weeks, and repeats. The 4% breakout often marks the start of these explosive bursts.
This mirrors physics: while velocity (v) may describe the stock’s general movement, momentum bursts are like sudden impulses. In physics, momentum (p) = mass × velocity.
In markets:
Let mass (m) = volume or liquidity
Let velocity (v) = price rate of change
Then, momentum (p) = volume × price velocity
A breakout of 4% or more is like a sudden force (F) acting over a short time (t), giving impulse:
Impulse = F × t = Δp
Thus, a 4% move is the "impulse" that shifts a stock into a new momentum phase.
Sometimes these 4% impulses are the signals for new moves, if the impulses are coming from big consolidation bases it makes bigger moves.
WHY 4?

1.0 46,539 47.1% 10.7% 0.71%
4.0 26,041 46.8% 12.8% 0.88%
4.5 22,906 46.8% 13.3% 0.94%
Observations:
Lower percentages (1-2%) generate MORE signals but slightly lower quality
4-4.5% shows the best average returns (0.88-0.94%)
Win rates are surprisingly consistent (45-47%) across all percentages
"Big wins" (≥10% in 5 days) increase with higher MB percentages
2. Why the Algorithm Chose 1%
The algorithm selected 1% because of its scoring formula:
score = win_rate * 0.3 + big_win_rate * 0.3 + avg_gain * 0.2 + signal_frequency * 0.2The 1% threshold won due to high signal frequency (46,539 signals), even though 4-4.5% had better returns. This suggests the scoring might be overweighting quantity.
3. Volume Analysis
1% MB: Average volume ratio = 2.24x
4% MB: Average volume ratio = 2.49x
10% MB: Average volume ratio = 3.17x
Higher price moves correlate with higher volume - this validates the momentum principle.
Output of Research:
Don't use 1% - Use 3.5-4.5% instead because:
Better average returns (0.81-0.94% vs 0.71%)
Higher "big win" rate (12.3-13.3% vs 10.7%)
More meaningful moves that justify trading costs
Still generates sufficient signals (22,906-29,183)
2. What This Data-Driven Article Will Reveal
Research on 1,227 NIFTY750 and SP500 stock breakouts from 2020 to June 2025 reveals key insights for traders:
High Success Rate: 82.31% of breakouts (1,010/1,227) gained ≥10% in 3-5 days.
Top Patterns: Bullish Three White Soldiers (39.05% success, 8.72% gain) and Dragonfly Doji (31.43% success, 7.17% gain) are most reliable.
Pre-Breakout Signals: Inside Bar (86-93%) and Doji (63-67%) dominate Days -3 to -1, signaling consolidation.
Volume Surge: Breakout day volume hits 1.93x average, with strong buying pressure (11.8M vs. 2.9M shares).
Trading Tips: Seek Engulfing/Hammer patterns, avoid low-volume breakouts, and confirm with 2x volume spikes.
High Success Rate of Breakouts Signals Opportunity:
Analyzed 1,227 breakouts, defined as a 4% or greater price increase from the previous close, accompanied by higher volume and a bullish candle. Remarkably, 1,010 of these breakouts (82.31%) achieved at least a 10% gain within 3-5 days, highlighting the potential of breakout trading when executed with precision.
Reliable Candlestick Patterns Drive Breakout Success:
Analysis, powered by the identify_candlestick_patterns_enhanced function, reveals that certain candlestick patterns are highly predictive of successful breakouts. The top performers include the bullish Three White Soldiers (39.05% success rate, 8.72% average gain) and Dragonfly Doji (31.43% success rate, 7.17% average gain), as shown in the "Pattern Reliability Analysis" section. Bearish patterns like Three Black Crows and Gravestone Doji also appear but are less reliable for bullish breakouts.
Volume Spikes Are the Breakout’s Fuel:
The "Volume Profile Analysis" section, supported by the analyze_volume_profile function, emphasizes the critical role of volume in confirming breakouts. On the breakout day, volume surges to 1.93x the 5-day average, with buying pressure (11.8M shares) significantly outweighing selling pressure (2.9M shares) and a 38.9% volume spike rate. Pre-breakout days show stable volume (1.01-1.02x average), while post-breakout volume drops off (1.15x on Day +1, 0.88x on Day +2). This pattern, derived from metrics like Volume_Ratio and BuyingPressure, indicates that a strong volume surge is essential for a breakout’s success. For traders, this reinforces the need to wait for a 2x volume spike on the breakout day to avoid false moves.

4. Conclusion
My research on 1,227 S&P 500 breakouts from 2020 to June 2025 offers a data-driven blueprint for traders, revealing an 82.31% success rate for breakouts achieving ≥10% gains in 3-5 days. By identifying reliable patterns like Three White Soldiers (39.05% success) and Dragonfly Doji (31.43% success), pinpointing pre-breakout consolidation signals (Inside Bar, Doji), and emphasizing the critical role of a 1.93x volume spike on breakout day, this study provides actionable insights. These findings, derived from my personal capabilities and knowledge, are a work in progress. While the research shows promising results, I’m actively backtesting it in real trades to refine its effectiveness. Please don’t take it as definitive advice—use it as a starting point and always conduct your own analysis.
P.S. In my next post, I’ll share insights on my 4% Momentum Burst Scanner and Dashboard, built in Python and backtested for nearly a year. Over the past 3-4 months, I’ve optimized it, achieving consistent weekly returns of 8% to 17%. Stay tuned for details!
