A financial standard for measuring asset price movements.
An index is a logical financial standard that is used to offer in-depth insight into the movements of asset prices. It usually takes the form of a financial instrument, with underlying technical indicators, serving to explain and even predict potential fluctuations in asset prices within a specific period. Depending on the effectiveness of an index, it may be very popular for general purpose market analysis or for particular assets and trend periods.
There are many indices for different exchange categories. S&P 500 is a popular financial index for measuring stock market performance and risk, while Total Crypto Market Capitalization Index (TCAP) is a similarly popular index for indicating the best performing cryptos at any specific time.
