BSE Group X is the segment of roughly 1,200 companies listed exclusively on BSE (not on NSE), mostly small and micro-cap names. Because most scanners are NSE-centric, Group X gets little coverage.

What does the Silent Accumulation score mean?

It is a 0-100 score that is high only when four signals line up together: a volume surge versus the 20-day average, larger-than-usual trade sizes, a buy-side lean inferred from the day’s candle, and a still-coiled price (small move, tightening range). Heavy volume with buying but little price move is the footprint of quiet accumulation before a move, rather than after it. It is educational, not investment advice.

How often does it update?

Once every trading day, after BSE publishes the end-of-day bhavcopy in the evening.

DOWNSTOX ORIGINAL · SILENT ACCUMULATION

BSE Group X Silent Accumulation Radar

Every volume-gainer list ranks stocks that have already moved. This one inverts it. It scans the ~1,200 exclusively-BSE-listed Group X micro-caps that NSE-centric scanners ignore, and surfaces the ones with heavy volume, larger-than-usual trade sizes and buy-side pressure while the price is still coiled. Heavy volume with buying but little price move is the footprint of quiet accumulation, before the move rather than after it.

Volume surge

Today’s volume against its 20-day average. The raw "volume gainer" trigger.

Trade size

Average trade size vs its own baseline. Bigger tickets point to larger hands, not retail churn.

Buy lean

Aggressive-buy share inferred from the day’s candle (our Auction Candle read).

Coil

Small price move and a tightening range. The "silent" part: volume without the pop, yet.

How the Silent Accumulation score works

Each BSE Group X stock is scored 0-100 from its daily bhavcopy history. The score rises only when four independent signals line up at once: a volume surge, larger trade sizes, a buy-side lean, and a still-coiled price. A stock that is already up sharply on volume scores lower, not higher, because it is no longer silent. Names are tagged Silent (coiled, pre-move), Igniting (breaking out on volume now), or Building. Everything is inferred from price and volume, not measured order-flow.

The exact calculation

Score = 100 x ( 0.34xVolume + 0.20xTradeSize + 0.24xBuy + 0.22xCoil )

Volume: (today volume / 20-day average, minus 1), scaled so 5x maps to full.

Trade size: today average trade size vs its own baseline (bigger tickets = larger hands).

Buy: aggressive-buy share inferred from where price closed in the day's range and the open-to-close path.

Coil: small close-to-close move (under 6%) times a range-contraction factor. Big move drives this to zero.

A name only appears if it clears three gates: volume at least 1.8x its 20-day average, at least ₹10 lakh traded today, and at least 8 sessions of history. Each factor is clamped to 0 to 1 before weighting, so no single input can dominate. Data is the daily BSE bhavcopy (open, high, low, close, volume, trade count); everything is inferred from price and volume, never measured order-flow or delivery data.

For education only, not investment advice. Downstox is not a SEBI-registered investment adviser or research analyst, and nothing on this page is a recommendation to buy or sell any stock. BSE Group X scrips are thin and highly volatile, with wide spreads and frequent circuit filters, so prices can move sharply on small volume. The Stealth score is an analytical footprint derived from public price and volume data. Do your own due diligence and consult a SEBI-registered adviser before investing.
