Sensex Contributors Today — Stocks Driving the BSE Sensex

Live tracking of which Sensex 30 stocks are pushing the BSE Sensex up or dragging it down today. The tables above split the 30 component stocks into positive contributors (pullers — adding points to the Sensex) and negative contributors (draggers — subtracting points). Each stock's contribution is a function of its weightage in the index and its price change. Use this page to understand what's actually driving today's Sensex move, identify sector rotation patterns, and find which heavyweight stocks are masking weakness or strength in the broader market.

How to Read Today's Sensex 30 Contributors

The two tables above split today's Sensex 30 stocks into two groups: stocks that have added points to the index (positive contributors / pullers) and stocks that have subtracted points (negative contributors / draggers). Each stock's contribution is a function of two things: its weightage in the Sensex (how much it counts) and its price change today (how much it moved).

A 1% move in a heavyweight like Reliance Industries or HDFC Bank moves the Sensex more than a 5% move in a lower-weighted stock. The points column shows the actual index points each stock added or removed — making it easy to see which 2-3 stocks are doing most of the work today.

Why this matters: the Sensex often moves due to 3-5 heavyweight stocks, not all 30. If the index is up but only 5 stocks are pulling it (and 20 are dragging), that's a narrow, sentiment-driven rally that may not be sustainable. Watch breadth — count how many of the 30 are green vs red — for a better read on market health than the headline number alone gives you.

Sensex 30 Stocks List with Live Weightage

The BSE Sensex includes 30 of the largest free-float market-cap-weighted companies listed on the Bombay Stock Exchange. Below is the complete list of Sensex 30 stocks with their current weightage in the index. Weightages are updated by BSE based on free-float market capitalisation and reviewed twice a year.

Sensex Pullers vs Draggers Explained

Pullers are the Sensex 30 stocks adding points to the index today (shown in the Positive Contributors table above). Draggers are the stocks subtracting points (Negative Contributors table). The labels come from trader vernacular — pullers "pull" the index up, draggers "drag" it down.

A stock's status as puller or dragger can change intraday. A morning puller can become an afternoon dragger if its price reverses. Track this through the session by refreshing the page or enabling auto-refresh — the contribution tables update every minute during BSE trading hours (9:15 AM to 3:30 PM IST).

The most useful pattern to watch: stocks pulling while the broader Sensex drags. These are stocks moving on company-specific news (earnings, deals, sector tailwinds), often unrelated to overall sentiment — and frequently the start of a multi-day uptrend in those specific names.

How Is the Sensex Calculated from Its 30 Stocks?

1. Free-Float Market Cap

BSE calculates the free-float market cap of each Sensex stock. Free-float means only the shares actually available for public trading — promoter-held, government-held, and locked-in shares are excluded. A company with a high market cap but most shares held by promoters has a lower free-float and therefore lower weightage.

2. Weightage Assignment

Each stock's weightage is calculated as: that stock's free-float market cap divided by the total free-float market cap of all 30 stocks combined. So if Reliance has a free-float market cap of ₹14 lakh crore out of a Sensex total of ₹120 lakh crore, its weightage would be roughly 12%.

3. Index Value Calculation

The Sensex value is the weighted sum of all 30 stock prices, scaled to a base value. The index value changes continuously through the trading session as the stock prices move. A 1% move in a 12%-weighted stock moves the Sensex by roughly 0.12% — explaining why heavyweight moves have outsized impact.
