Level and change
The level is the index value now. The change is against the previous close, in points and in per cent. A 1% move in NIFTY is a big day; most days are smaller.
P/E and P/B
Price-to-earnings compares the index price to the profits of its companies. A higher P/E means investors are paying more for each rupee of profit. Compare it with the index's own history, not with other indices.
Breadth
Breadth counts how many shares rose and fell. If NIFTY is up but most shares are down, a few big names are carrying the index.
52-week range
The highest and lowest level of the last year. Where today sits inside that range tells you whether the index is near a top, a bottom or in the middle.
