What are index funds?
Index funds are a way of gaining exposure to an investment market. Most investment markets have indexes that measure their value over time. Indexes cover almost every industry sector and asset class, including U.S., European, Asian and international shares, property, bonds and cash.
How is indexing different to active management?
Active fund managers try to outperform the index by picking sectors and securities they believe will outperform in the future.
Rather than trying to guess which investments will outperform in the future, index managers replicate a particular market or sector. This means they invest in all or most of the securities in the index.
Indexing is based on the theory that investors as a group cannot beat the market – because they are the market. In fact, when you take costs into account This is why when you look at the performance tables at any point in time there are always winners and losers. Picking consistent out-performers is almost impossible, so indexing provides a way of accessing market performance without the high costs.
