Question 1

What is a stock bubble chart?

Accepted Answer

A stock bubble chart draws every listed company as a circle and packs two numbers into each shape: its size and its colour. On this page, size measures how hard a stock moved today and colour marks the direction of that move. You read an entire market in one glance instead of scrolling a table of 150 rows.

Question 2

How do I read the Nigeria stocks bubble chart?

Accepted Answer

Start with the biggest bubbles. In Today's Top Movers they mark the largest percentage moves of the session, whether the stock rose or fell. Hover any bubble to see its price, market cap, and 7-day and 1-month change. Click a bubble to open that company's full stock page.

Question 3

How often does the NGX bubble chart update?

Accepted Answer

Prices refresh roughly every 20 minutes while the Nigerian Exchange trades, from 9:00am to 4:00pm WAT, Monday to Friday, public holidays excluded. Outside those hours the chart shows the closing prices from the most recent session.

Question 4

Which Nigerian stocks are the biggest by market cap?

Accepted Answer

Sort the chart by Largest by Market Cap and the heavyweights take over the canvas: MTN Nigeria, Dangote Cement, Airtel Africa, BUA Foods, Seplat Energy and the tier-1 banks. Bubble size then follows company value rather than today's move.

Question 5

How does the bubble chart differ from the NGX heatmap?

Accepted Answer

Both visualise the same prices, but they answer different questions. The heatmap packs stocks into a tight grid of tiles, so it suits scanning sector blocks side by side. The bubble chart spreads stocks into a swarm you can drag apart, so it surfaces individual outliers faster.

Question 6

Does the chart cover every company listed on the NGX?

Accepted Answer

The chart covers every Nigerian Exchange company we track, across all sectors: banking, oil and gas, consumer goods, ICT, industrial goods and agriculture. Choose 25, 50, 100, 150 or all stocks from the count selector, and use the sector filter to focus on one sector at a time.

Question 7

Is the Nigeria stocks bubble chart free to use?

Accepted Answer

Yes. The chart needs no account and sits behind no paywall. You can also pull the same NGX prices through the NGN Market API if you want them inside your own app, dashboard or spreadsheet.
