Indices are a key instrument in equity markets and lie at the center of modern investing and portfolio management. They are designed as a basket of stocks where each constituent has a specific value, and the index’s overall level (a numerical value or ‘price’) fluctuates according to the securities’ moves.
Composed of the largest or most representative companies by geography, sector or any other strategy, indices gauge — or benchmark — the overall underlying market’s performance, reflecting its ups and downs, and its long-term returns.
STOXX and DAX indices
30+ years of liquid and transparent access to markets across the globe.
Traditionally, index constituents were chosen for their market capitalization (traded value), with the biggest stocks having a proportionally larger weight in the index, and hence a more influential sway. In recent years, other selection criteria have emerged to allow for alternative investment strategies, such as sustainability, thematic or factor investing. What hasn’t changed is the need for indices to be rules-based, transparent and objective.
Many indices have become well-followed barometers of investor sentiment, especially those that track the world’s most important markets. In Europe, benchmarks such as Germany’s 40-stock DAX®, established in July 1988, and the Eurozone’s EURO STOXX 50®, introduced almost a decade later, guide a large population of institutional and private investors in making investment decisions every day. Qontigo manages more than 16,000 indices, while the Index Industry Association estimates there are nearly 3 million indices in the world.
In recent years, in what has been called the passive-investing boom, investors have turned to index-tracking products for their efficiency and low cost. These products — which include exchange-traded funds (ETFs), futures and options — follow the move of indices, leaving out any particular preference, or ‘active’ decision, of the investor. Thanks to the practicality of these products, indices have thus also become tools with which retail investors can implement their investment views.
