Tata Nifty Private Bank Exchange Traded Fund NAV history

Net asset value: what one unit of the fund is worth, the value of everything the fund holds less what it owes, divided by the units in issue. The fund house works it out after every business day, and buying or selling units is done at the NAV of the day.

Units of an ETF are bought and sold on the exchange at whatever price buyers and sellers agree, all through the day. The NAV is what a unit holds, worked out once after the day ends. The two are usually close, because large investors can create or redeem units at the NAV, and the gap between them is the premium or discount shown at the top of the ETF's page.

In those years the NAV changed level once without the market moving it, as when units are split, so a high before the change and a low after it would compare two different scales.
