Delivery Accumulation

From NSE's daily delivery dataRead about it

When the share of volume taken into demat accounts keeps rising, someone is building a position rather than trading in and out. A signal comes when a stock's 10-day average delivery share reaches its highest in six months while the stock is in an uptrend near its high.

How sturdy is it?

The same rules, tested again with one thing changed. A result worth trusting holds up across these; a big swing means the headline figure depends on luck or on the exact setup.

How the tests work

Universe. The 500 most-traded NSE stocks at each date, by six-month average traded value, re-ranked every month: 1,353 different stocks over the years, 131 of which no longer trade. Testing all of them, not only today's survivors, keeps the results honest.
Period. 1 Jan 2016 to 1 Oct 2026, after a year of history for the long averages, on NSE's own end-of-day files: prices, delivery and futures open interest.
Portfolio. 10 slots, each a tenth of the portfolio's value when a trade opens. A signal at a day's close opens at the next day's open; an exit rule met at a close closes the trade at the next open. When there are more signals than free slots, the strategy's own ranking decides.
Costs. 0.2% on each side of every trade (STT, stamp duty, exchange charges and slippage). Tax and DP charges are not included.
Market filter. Every strategy is also tested opening new trades only while the Nifty 500 closes above its 200-day average. At the last close it was below it.
Robustness. Each strategy is run again with costs doubled, with 5 and with 20 stocks at a time, and judged separately in each half of the test. A result that only holds in one setup is luck, not an edge.
Corporate actions. Splits, bonus issues and demergers are applied from NSE's corporate-actions list, and symbol changes are joined up, so none of them shows up as a gain or a loss.
What is left out. Dividends (as in the Nifty 500 price index it is measured against), taxes, and the chance that a large order moves a thinly traded price.
