What index trading means
A stock index is a number that tracks the prices of a defined group of shares, such as large US technology companies or the biggest firms listed in Germany. You cannot buy an index directly. You can buy a fund that follows it, trade a futures contract on it, or trade an index CFD.
A CFD (contract for difference) is an agreement with a broker to settle the change in price between opening and closing a position. You never own the shares. Most index trading by retail traders happens through CFDs, so this section focuses on them. Start with Index CFDs explained if the term is new to you.
Index CFDs are traded with leverage, which means borrowed exposure. A small move in the index can produce a large gain or loss relative to your deposit, and losses can build up fast.

How an index is calculated
The weighting method decides which companies move the index most:
- Price-weighted: shares with a higher price carry more weight, whatever the size of the company. The Dow Jones and the Nikkei work this way.
- Market-cap weighted: larger companies by market value carry more weight. Most modern indices use this method, often counting only freely traded shares ("free float").
| Instrument | Underlying index | Weighting | Guide |
|---|---|---|---|
| USTEC / NAS100 | Nasdaq-100 | Modified market cap | USTEC, NAS100 |
| US30 | Dow Jones Industrial Average | Price | US30 |
| US500 | S&P 500 | Free-float market cap | US500 |
| DE30 | DAX | Free-float market cap | DE30 |
| UK100 | FTSE | Free-float market cap | UK100 |
| JP225 | Nikkei | Price | JP225 |
Each instrument page lists what the index holds, how it is built and which sectors dominate it.
What moves stock indices
- Company earnings, especially from the heaviest-weighted members.
- Interest rates and central bank decisions: higher rates tend to weigh on share valuations, growth and technology stocks in particular.
- Economic data such as inflation, jobs and output figures.
- Currency moves: a weaker yen or pound can lift exporters in JP225 or UK100.
- Risk sentiment: geopolitical news and market stress often move all indices together.

Legal position in Pakistan
In Pakistan, the regulator is the Securities and Exchange Commission of Pakistan (SECP), with trading in listed securities and commodities only via SECP-licensed securities and futures brokers. On offshore platforms, per the SECP, offshore forex/CFD platforms operate without regulatory approval in Pakistan, and per the SECP, offshore platforms have no Pakistani licence or oversight and offer no legal protection or recourse. On resident purchases, per the SBP, the purchase of offshore forex/margin/CFD products by Pakistani residents violates section 4(1) of FERA 1947. Read Law and regulators before opening any account. For local shares, see PSX basics.
Frequent questions
Is an index CFD the same as investing in an index fund?
No. A fund holds the shares. A CFD only settles price changes, uses leverage and usually carries overnight financing costs.
Why do US30 and US500 sometimes move differently?
US30 is price-weighted and holds far fewer companies, so a single high-priced share can move it. US500 is broader and weighted by market value.
What is the difference between USTEC and NAS100?
Both names refer to CFDs on the Nasdaq-100. The name depends on the broker.
Can I lose more than a small move suggests?
Yes. With leverage, a modest move in the index can wipe out a large part of your margin. Plan your stop-loss and position size before you trade.
When are indices most active?
Usually around the opening hours of their home exchange and during major data releases. Check Pakistan times with the session converter.
