The NSE website, although sometimes laggy and devoid of any data at all for particular securities, is indeed helpful for testing strategies. I was pondering over the delivery volume percentage data and the relative changes in prices of the particular stock. It can be seen that two possible situations are arising:
- Whenever the equity delivery percentage is greater than roughly 65%, on say day 't', there is a spike observed in the price on the day 't+1'. This is the most likely case observed.
- The other possibility is the stock price spikes on the day 't+2'.
- Of all the cases observed, there had no need to be worried about holding the stock.
I was going through the data for Emami Ltd, Birlacorp, DBCorp, Sun Pharma, and Eveready Industries and it seems that most of the time the hypothesis holds true.
