Chapter 03 · Reading price and volume
Volume and urgency
Volume is the number of shares that actually changed hands. It measures participation, not virtue. This chapter shows how to read it next to price, and which popular phrases overclaim what the number can prove.
What the number counts
If 4 lakh shares trade, 4 lakh were bought and 4 lakh were sold. Volume is not ‘buying volume’ by itself. Every share traded had both sides. What people mean by urgent buying is something else: price rose while a lot of shares traded, which means buyers were willing to pay up to get filled. Urgent selling is the mirror: price fell on heavy trade, so sellers were willing to accept less.
A rise on thin volume means the price moved without many people agreeing. That can be the start of something, and it can be a few orders in a quiet book. A rise on heavy volume means more of the market participated in paying higher prices. It still does not tell you whether they were right about the business. It tells you the move was contested and then resolved upward, for that session.
Compare volume with its own recent past
Absolute volume is hard to use. A large-cap trading 80 lakh shares is ordinary. A small-cap trading 80 lakh shares may be a frenzy or a data error. Compare today’s volume with the same stock’s recent typical day. A 20-day average is a simple yardstick: today was twice a normal day, or half of one. The yardstick is descriptive. It does not become a buy rule just because you computed it.
| Price | Volume versus recent average | A careful reading | An overclaim |
|---|---|---|---|
| Up | Much higher | Buyers paid up, and many shares agreed to the higher price. | The stock will continue tomorrow. |
| Up | Much lower | The rise happened without broad participation. | The rise is fake and must reverse. |
| Down | Much higher | Sellers accepted lower prices in size. | The company is finished. |
| Down | Much lower | The decline was not widely joined. | It is safe to buy because selling was weak. |
Climax and drought
A single day that trades several times the recent average, after a long rise, is often called a climax. It can be late buyers. It can also be a rebalancing, a block deal, an index addition, or the day a large holder finished selling into strength. You cannot see which from the volume bar alone. What you can do is refuse to treat that day as an ordinary day. Note it. See whether the next few sessions hold the price or give it back.
A drought — many sessions of shrinking volume while price drifts — means the disagreement has gone quiet. Breaks out of a quiet period matter more than breaks out of a noisy one, because the quiet period set a low bar for ‘unusual’. They still fail. A quiet stock can break higher on one enthusiastic fund and be back inside the range by the end of the week.
Delivery percentage is a second lens, not a moral one
Exchanges publish how much of the day’s volume resulted in delivery into demat accounts rather than being squared off. A high delivery percentage means more of the shares stayed with holders past settlement. A low one means more of the day’s excitement was intraday. Neither is good or bad by itself. A high delivery day on a falling price means holders took delivery of a lower price. A low delivery day on a rising price means the rise was rented. Use it as a description of who stayed, and check the exchange’s own file rather than a number copied into a forum post.
What to remember
- Volume counts shares traded. Every trade has a buyer and a seller.
- Read volume against the same stock’s recent days, not against a different company.
- Price up on heavy volume means buyers paid up. It does not mean they will be glad next month.
- A climax day and a block deal can look identical on the bar.
- Delivery percentage tells you who stayed past settlement. It is not a buy or sell label.
