What is a market index?
You cannot judge the mood of the whole market by staring at one company. So the exchange bundles many companies together into a single number called an index. When that number goes up, it means most of those companies gained value that day; when it falls, most lost value. An index is like a thermometer for the market's health — one quick reading instead of checking hundreds of stocks one by one.
DSEX — the whole-market thermometer
DSEX is the main, broad index of the Dhaka Stock Exchange. It tracks a very large group of listed companies, so it gives you the big-picture mood of the entire market. When the news says the market was up or down today, they almost always mean DSEX. If you only ever watch one number, this is the one — it tells you whether the market overall is having a good day or a bad one.
DS30 — the big, blue-chip companies
DS30 follows just 30 of the largest, most actively traded, well-established companies — the household names. Because these are the heavyweights, DS30 tells you how the strongest, most stable part of the market is doing. Sometimes the big companies move differently from the crowd, so comparing DS30 with DSEX can hint at whether investors are favouring safe giants or smaller names.
DSES — the Shariah index
DSES is the Shariah index. It tracks only the companies that meet Islamic finance principles — for example, businesses that are not built on interest-based earnings. If you prefer to invest in a way that follows Shariah guidelines, DSES shows you how that slice of the market is performing. It is a helpful reference for faith-conscious investors.
Why the index moves up or down
An index rises when, overall, more money is flowing into shares than out — buyers are confident. It falls when sellers dominate and confidence dips. News, interest rates, company results, and the general economic mood all push it around. A single day's move is just noise; what tells a real story is the direction over weeks and months.
How to use the index as an investor
- Use DSEX to gauge the overall market mood before making decisions
- Do not panic over one red day — look at the trend over time instead
- A falling index does not mean every company is bad; strong businesses can still shine
- The index sets the weather, but you still choose which specific company to own
