What is a characteristic of a quantity-based index?

• A. Fixed quantity of contracts per commodity
• B. Stable price fluctuations over time
• C. Equal weight adjustment regardless of commodity
• D. Standardized return on investments only

Answer: (A)

A quantity-based index is designed to measure the performance of a portfolio of commodities based on their physical quantities rather than their prices. One of the defining characteristics of this type of index is that it maintains a fixed quantity of contracts per commodity. This means that the index weights are determined based on predetermined quantities, which allows investors to track the performance of commodities in a manner that reflects their actual holdings or trades in physical markets.

By relying on fixed contracts, a quantity-based index can provide a more stable representation of the commodity's market performance, as it is less influenced by price volatility. In this way, it serves investors interested in assessing the performance of physical assets themselves rather than simply the monetary values attributed to them.

The other options do not accurately characterize a quantity-based index. For example, stable price fluctuations, equal weight adjustments, and standardized returns are not core features in the structure of quantity-based indices, which focus strictly on the contractual quantities of physical commodities involved.
