In depth
The 52-week high is a rolling number, so it changes as old data drops out of the window even when the price does nothing at all. It is widely used as a screening filter and as a psychological reference, and behavioural research has documented that investors anchor on it heavily — which is a fact about investors, not about the security. A price near the 52-week high is neither a signal to buy nor to sell; it is a description of where the price has been. Providers differ on whether they adjust the figure for splits and bonuses, and unadjusted series produce nonsense after any corporate action.
Worked example
A stock's 52-week high is ₹480, set eleven months ago, and it now trades at ₹456, which is 456 / 480 = 95% of that high. Next month the ₹480 print rolls out of the window and the 52-week high falls to the next-highest price, with no trade having occurred.
