Bollinger Bands wrap two standard deviations around a 20-day moving average, expanding and contracting with volatility. When a stock closes above the upper band, it has broken out of its normal range with force. This scan lists NSE stocks closing above their upper Bollinger Band.
Momentum traders read an upper-band breakout as a volatility expansion in the bullish direction, often after a period of tight, "squeezed" bands.
A close above the upper band is not automatically overbought — in strong trends price can "ride the band" for days. Equally, it can mark a short-term blow-off.
This is a Volume & Price Action scan. AlphaGrid computes it across 2,000+ NSE-listed stocks using end-of-day and intraday price data, refreshing through the trading session. Results are ranked and can be opened in the full screener, where you can add your own conditions and set alerts.
It means price has pushed more than two standard deviations above its 20-day average — a volatility breakout. In strong trends stocks can keep riding the upper band.
A break above the upper band signals strong upside momentum, especially after a squeeze. But it can also precede a pullback, so confirm with trend and volume.
