Stellenbosch University researchers have developed South Africa's first fine wine index, demonstrating the positive value of wine as an investment. The study, titled "Cheers to Enhanced Portfolio Performance: Wine as a Unique Asset Class," explores the impact of fine wine on portfolio growth and diversification.
The index is comprised of the top ten South African fine wines selected based on liquidity, monetary value, and the expertise of wine critics, and serves as a proxy for the Growth-Optimal Portfolio.
The index uses a repeat-sales regression methodology and the growth-optimal portfolio principles to determine which wines have a greater long-term return on investment. By employing three key portfolio strategies-the minimum variance portfolio, maximum growth rate, and the maximum Sharpe ratio, the study hopes to emphasise a nuanced approach that considers both financial and behavioral aspects of investing in assets for enjoyment and investment.
The research demonstrates a positive impact on portfolio growth and diversification by incorporating the wine index, offering investors a unique avenue for diversification in their portfolios. This marks the first successful attempt to construct a wine index in the South African investment landscape, providing a valuable addition to available financial instruments.
In assembling the roster for the South African wine index, a meticulous approach governs the choice of the top ten fine wines. Factors such as trading volume, indicating liquidity, the economic value of the wines, and a holistic evaluation of quality and reputation, as gauged by wine critic Tim Atkin's (TA) average ratings spanning the last five years, constitute the pivotal criteria.
he curated list of wines reflects a delicate equilibrium between market liquidity and outstanding quality, rendering them apt components of the esteemed wine index.
The authors hope the study will inspire further research and investment opportunities, promoting the recognition and appreciation of South African wines in global markets.
