Every trading day, NSE publishes a file called the Bhav Copy — an official settlement record for every stock traded. Buried inside it is one number that most retail investors completely ignore: **delivery percentage**.
This post explains what it is, what it actually tells you, and — just as importantly — what it does *not* tell you.
## What Is Delivery Percentage?
When you buy shares on NSE, you have two choices:
1. **Intraday (MIS)**: You buy and sell within the same session. No shares actually change hands.
2. **Delivery (CNC)**: You buy and hold. The shares settle in your demat account within T+1 days — real ownership transfer happens.
**Delivery percentage = (delivery quantity ÷ total traded quantity) × 100**
If RELIANCE traded 10 lakh shares today and 7 lakh settled as actual delivery, the delivery percentage is 70%.
NSE publishes this number every trading day for every stock in the Bhav Copy CSV file.
## What High Delivery Percentage Means
A high delivery % (above a stock's own 20-day average) means:
- A larger-than-usual fraction of buyers chose to *hold* rather than trade intraday
- Both sides of the transaction committed to actual ownership transfer
- The session was less speculative than usual for that stock
**Example from real NSE data:** On a day when CARBORUNIV had 95.5% delivery (vs its 20-day average of around 55%), nearly everyone who bought chose to hold. That's a meaningful signal that participants had conviction — regardless of direction.
## What High Delivery Does NOT Mean
This is the part most analysis gets wrong.
**High delivery does not tell you who was buying.**
When delivery is high and price goes up, it *could* be institutional accumulation. But it could equally be:
- Retail investors buying on positive news
- A promoter group increasing their stake
- A mutual fund rebalancing their index holdings
- Large retail HNIs buying for a long-term position
The delivery side of a trade includes **both the buyer and the seller**. A large FII selling to retail investors generates exactly as much delivery as a large FII buying from retail investors.
**The only way to confirm institutional direction is through NSE's separately disclosed Bulk Deal and Block Deal data** — which names the counterparty and specifies BUY or SELL.
## The 20-Day Average Benchmark
Raw delivery % is less useful than delivery % *relative to that stock's own history*.
A stock that normally trades with 80% delivery having a 60% delivery day is notable — more speculation than usual. Conversely, a stock that normally trades at 35% delivery seeing a 65% day stands out significantly.
This is why YouStockAI computes a **Delivery Score (0–100)**:
- Score 50 = today's delivery is in line with the stock's own 20-day average
- Score 70+ = delivery is significantly above average — participants more committed than usual
- Score 30− = delivery below average — more speculative/intraday activity than usual
## When Delivery Percentage Is Most Meaningful
The signal is strongest when:
1. **High delivery + rising price**: Committed buyers at current levels. Worth watching.
2. **High delivery + falling price**: Committed sellers. Could be distribution.
3. **High delivery on a low-delivery market day**: The stock stands out when the broader market is speculative.
4. **3+ consecutive days of above-average delivery**: Sustained commitment, not a one-day anomaly.
## Limitations to Keep in Mind
- **It's EOD data**: Delivery % is only available after 6 PM on trading days. Not useful for intraday decisions.
- **It doesn't tell you the price**: High delivery at ₹500 is different from high delivery at ₹5000.
- **Sector matters**: Banks and large-cap stocks naturally have higher average delivery than small-caps.
- **It cannot confirm institutional activity**: For that, check NSE's Bulk Deal and Block Deal disclosures directly.
## How YouStockAI Uses Delivery Data
On the [Delivery Intelligence page](/public/dashboard), YouStockAI shows:
- **Market delivery regime**: Is today's market-wide delivery above or below the 30-day average?
- **High Conviction Sessions**: Stocks with above-average delivery AND a green close
- **Delivery Streaks**: Stocks with 3+ consecutive days of above-average delivery commitment
- **Sector Delivery Pulse**: Which sectors are seeing more ownership commitment than usual
- **FII/DII Bulk & Block Deals**: The actual confirmed institutional transactions from NSE disclosures
All framed as data — not as buy/sell recommendations. You interpret the context; you decide.
