Best forRetail investors
ReviewedPricing: Free

Bubble Screener is a free website that draws the stocks in an index as bubbles that show each stock's performance over a day, week, month or year. It covers US, Indian, UK, German and French indices. There is no paid plan; the site notes that data can be delayed a few minutes.

The bottom line

A fast, free visual pulse-check on major stock indices — best for a quick macro read, not deep fundamental analysis.

What it really isBubble Screener: a free bubble-chart viewer for stocks in major market indices.
Our takeBubble Screener turns an index into a picture: each stock is a bubble showing its move over the chosen period.
You can switch what the bubble shows (performance, price, market cap or volume), what sets its size and the colour scheme, and see top gainers and losers. It covers the S&P 500, NASDAQ 100, Dow Jones, Nifty 50, Sensex, several sector Nifty indices, FTSE 100, DAX and CAC 40. It is free, with no account needed.
Why we rate itHard to fault a zero-cost tool that delivers genuine at-a-glance market insight.
The bubble-chart format makes sector rotation and daily gainers/losers intuitively readable in seconds.
The catchNo fundamental screening filters, no alerts, no portfolio integration, and no API.
Useful for a macro visual snapshot but stops well short of a full stock screener.
