- The 4% breakout flags a stock that closed up at least 4% on the day, on volume greater than the prior session, with enough liquidity to trade. It is a same-day event, not a trailing rank.
- Volume is half the rule, not a footnote. A 4% up-close on light volume is noise; a 4% up-close on a heavier tape is a footprint. Pradeep Bonde’s canonical version also wants institutional participation, roughly nine million shares.
- It is the trigger layer of the Stockbee family. The persistence and acceleration screens tell you a stock has been strong for weeks; a 4% breakout tells you it just did something forceful on top of that.
- The screen fires on one-day events, which is its strength and its weakness. It catches the thrust the day it happens, and it also fires on spikes that go nowhere. The chart and the base decide which is which.
- In the terminal,
boreturns today’s 4% breakouts. It is an event flag rather than a ranked score, so it pairs best with the persistence screens:(dt or mdt) and bofinds extended names that just broke out.
What the screen catches
The 4% breakout is the most literal screen in the Stockbee family. It asks one question about the most recent session: did this stock close up at least 4% over yesterday, on volume greater than yesterday, and is it liquid enough to trade. If all three are true, the name is flagged. There is no trailing window, no ranking, no percentile. It is a snapshot of a single forceful day.
That single day carries weight because it is usually how a momentum burst announces itself. A stock that has been basing quietly does not drift into a new trend; it gaps or drives up 4%, 6%, 8% on a heavy tape as institutions start accumulating, and that first big up day is the tell. The screen exists to surface those days across the whole universe on the evening they print, before a moving average or a trailing return has registered anything at all.
This is what makes it different in kind from Double Trouble or Trend Intensity. Those measure how far or how fast a stock has already traveled over weeks and months. The 4% breakout measures what just happened today. It is the fastest of the momentum screens, and the noisiest.
The 4% breakout is one bar: a 4%+ up-close on volume greater than the prior session, out of a quiet base. The volume spike is what separates it from a routine up day.
Why volume is half the rule
A 4% move on its own is close to meaningless. Small and mid-cap stocks move 4% on quiet days all the time, on no news and no buyers of consequence, and those moves fade by the next session. What turns a 4% up-close into a signal is who did the buying, and volume is the only visible proxy for that.
So the screen demands that today’s volume exceed the prior day’s, and Bonde’s canonical version goes further, requiring roughly nine million shares to confirm that institutions, not just retail, are involved. The logic is simple: a 4% jump on light volume is a stock wandering; a 4% jump on a heavy tape is a stock being bought by someone with size. tickerstance enforces a liquidity floor on the dollar volume so the screen only returns tradeable names; it drops the thin, illiquid moves that look explosive but cannot be acted on.
The pairing of price and volume is the whole point. Either one alone is a weak signal. Together they describe a specific event: a hard up day that a large buyer paid for. That is the raw material of a momentum burst, and it is what the screen is built to isolate.
Where the 4% breakout misleads
The screen’s speed is also its flaw. Because it looks only at today, it cannot tell a first push from a last gasp. A 4% breakout out of a long, quiet base is the beginning of something; a 4% up day after a stock has already run 40% is often the exhaustion move that ends it. The flag looks identical in both cases. Only the chart and the base structure behind the bar can tell them apart.
It also fires constantly in a strong tape and falls silent in a weak one, which is a feature but catches people out. On a broad up day the screen can return hundreds of names, most of which are simply riding the market rather than starting individual bursts. On a heavy down day it returns almost nothing. The count is a rough read on the day’s character, not a curated list.
And a single day is a single day. Plenty of 4% breakouts give it all back the next open. The screen is a trigger, not a thesis: it tells you a name pushed hard today, and nothing about whether the move survives the week. That is why it is built to sit on top of the slower screens rather than stand alone.
How tickerstance uses it
In the terminal, bo returns the names that cleared the 4% breakout today: up at least 4% over the prior close, on higher volume, above the liquidity floor. Because it is a yes-or-no event rather than a ranked measurement, the list carries the Double Trouble ratio as its score column so you still have a sense of how extended each breakout is, but the breakout itself is a flag.
The screen earns its keep in combination. (dt or mdt) and bo finds names that are both extended off a base and breaking out today, which is far stronger than either signal alone. bo rs>90 keeps only breakouts in strong names. Its close cousin dbo, the dollar breakout, catches the same kind of decisive session measured in raw dollars instead of percent, and the two are often run together.
The 4% breakout is a name-level event, computed fresh on the most recent bar and reported beside the leaderboards; it plays no part in Stance. Its best use is as the trigger that confirms a slower read. A name that was already extended and accelerating, now with a loud high-volume day on top, is a much sharper candidate than the breakout alone.
Frequently asked questions
What is a 4% breakout?
A same-day momentum screen from Pradeep Bonde’s Stockbee work. It flags a stock that closed up at least 4% over the prior session, on volume greater than that prior session, with enough liquidity to trade. Bonde’s canonical version also wants roughly nine million shares to confirm institutional participation. It is the loud, high-volume up day that tends to start a momentum burst.
Why does the 4% breakout require higher volume?
Because a 4% move on its own is common and meaningless. Small and mid-cap names move 4% on quiet days all the time and fade the next session. Volume is the only visible proxy for who is buying, so the screen demands today’s volume exceed the prior day’s: a 4% jump on light volume is noise, while a 4% jump on a heavy tape is a footprint left by a buyer with size.
How is the 4% breakout different from Double Trouble?
Double Trouble measures how far a stock has traveled from its 252-day low, a read on weeks or months of trend. The 4% breakout looks only at today: a single 4%+ up-close on rising volume. One tells you a stock has been strong for a while; the other tells you it just did something forceful right now. They are meant to be layered, not chosen between.
Is a 4% breakout a buy signal?
No. It reports that a stock had a strong high-volume up day; it does not tell you to buy. The flag fires on first pushes out of clean bases and on last-gasp exhaustion moves alike, and plenty of 4% breakouts reverse the next session. Whether one is worth acting on depends on the base structure, the market regime, and your plan.
How do I screen for 4% breakouts on tickerstance?
Type bo in the terminal for today’s 4% breakouts. Because it is an event flag, it pairs best with the persistence screens: (dt or mdt) and bo finds extended names that also broke out today, and bo rs>90 keeps only breakouts in strong names. Its dollar-based cousin is dbo, the dollar breakout.
