Võrdlusindeksite

Võrdlusindeksid, often translated as comparison indices or benchmark indices, are statistical tools used to measure and represent the performance of a specific market segment or asset class over time. These indices are constructed by selecting a representative sample of securities, such as stocks or bonds, and calculating their aggregate performance based on predetermined rules. The most common example is a stock market index, which tracks the movement of a basket of stocks to provide a snapshot of the overall market's health or a particular sector's performance.

The primary purpose of võrdlusindeksid is to serve as a benchmark. Investors and portfolio managers use them to evaluate the success of their investment strategies. If an investment portfolio outperforms the relevant võrdlusindeks, it suggests a successful active management approach. Conversely, underperformance indicates that the strategy may not be as effective as simply investing in the index itself.

Võrdlusindeksid are also crucial for passive investment strategies, such as index funds and exchange-traded funds (ETFs). These funds aim to replicate the performance of a specific index, offering investors a diversified and low-cost way to gain exposure to a particular market. The methodology for constructing and weighting the components of an index can vary, with common weighting schemes including market capitalization, price, or equal weighting. The selection and maintenance of constituents are typically managed by index providers, who ensure the index remains representative and relevant.
