Trading Stock Indices: S&P 500, DAX and Nasdaq

What are stock indices?

Stock indices are gauges of the health of entire capital markets. The S&P 500, NASDAQ and DAX are the three most liquid indices available via CFDs, offering exposure to hundreds of companies in a single trade. Trading indices is less risky than trading individual stocks because the risk is diversified — the bankruptcy of one company will not destroy the index.

Indices are not assets you can "own" in the traditional sense — they are mathematical constructs. Index CFDs let you trade their change in value without buying the individual companies. That is particularly convenient for trading, where what matters is the price move, not dividends or ownership rights.

Trading an index is like owning the whole forest instead of a single tree. One tree may wither, but the forest survives.

S&P 500, NASDAQ, DAX

The S&P 500 covers the 500 largest US companies and is treated as a gauge of the American economy. The index is capitalisation-weighted — Apple, Microsoft and Amazon have the greatest influence on its value. The S&P 500 shows a long-term upward trend of 8-10% per year on average after inflation.

The NASDAQ Composite is more technology-oriented — it includes Apple, Microsoft, NVIDIA and other tech giants, which makes it more volatile. In 2020-2021, the NASDAQ outpaced the S&P 500 thanks to the technology boom. In 2022, as interest rates rose, the NASDAQ fell more than the S&P 500 — higher volatility works both ways.

The DAX is the German index of the 40 largest companies, key for the euro area. It includes companies from the automotive (Volkswagen, BMW), chemical (BASF) and engineering (Siemens) sectors. The DAX reacts strongly to ECB decisions and German export data.

💡 Practical tip: The NASDAQ is more volatile than the S&P 500, which means bigger profit opportunities — but also bigger losses. With the same capital, use a smaller position size on the NASDAQ than on the S&P 500.

Session hours

The greatest volatility occurs in the first hour after Wall Street opens (15:30 CET) and before the close (20:00). The European session (8:00-15:30) is usually calmer, except for EU economic data releases. Trading index CFDs allows exposure outside exchange hours, but liquidity is lower and spreads are wider.

The first hour of the US session is the hour of peak activity — it generates around 30% of daily volatility. It is an ideal window for day traders, but it demands quick reactions and strict risk management. Swing traders often enter at the start of the European session, when prices are more stable.

Trading strategies

Trading strategies on indices include day trading the volatility around macro data, swing trading based on support and resistance levels, and trend following using moving averages. Indices tend to rise over the long term, which makes long positions statistically more favourable — historically, the S&P 500 rises in around 73% of weeks.

Summary

Stock indices are the foundation of any CFD portfolio. The S&P 500 as a gauge of the US economy, the NASDAQ as exposure to technology, the DAX as the representative of the European market. Start with the S&P 500 — it has the best liquidity, the broadest diversification and the most predictable behaviour.
