52-Week High / Low
The 52-week high is the highest price at which a security has traded over the trailing one-year period, and the 52-week low is the lowest price over that same window. On NSE these levels are computed from intraday traded prices across the rolling 52 weeks (roughly 252 trading sessions) and are commonly shown on quote pages for cash-market stocks and indices, and referenced for some F&O underlyings. The figures update continuously as new sessions are added and the oldest ones roll off.
Also called: 52 Week High Low, 52-Week High, 52-Week Low, 52 Week High / Low, Fifty-Two Week High/Low, 1-Year High/Low, Yearly High Low
How it is read
Traders often use these two levels as a quick reference for where the current price sits within its one-year trading range. A price near the 52-week high places it at the upper end of the past year's range, while a price near the 52-week low places it at the lower end; some market participants also watch whether a price is making a "new" 52-week high or low relative to recent sessions. The levels are typically read as context or framing for the prevailing trend rather than as standalone signals.
What it does not tell you
These figures describe only past traded prices and say nothing about future movement, fair value, or the reasons behind a move. The range can be distorted by a single spike on illiquid scrips, by corporate actions (splits, bonuses, dividends) if the series is not adjusted, and by the rolling window itself, so a "new low" may simply reflect an old high dropping out of the 52-week period. A 52-week level also does not indicate liquidity at that price, nor does proximity to a high or low imply anything about how the price will behave next.
