2.1 Introduction
In portfolio optimisation, investors should keep in mind that diversification is key to balance risk and return. Malkiel (2010), reminded investors that the best investment is a well-diversified portfolio, being re-balanced appropriately while adopting a buy-and-hold strategy. A reduction in portfolio volatility can be achieved by diversifying in several securities. However, even with a large number of assets, risk cannot be reduced to zero since portfolios are affected by macroeconomic factors which influence the market (Bodie et Al., 2004). In addition, portfolio returns can never be guaranteed as the future is unpredictable. A famous quote by a Chinese philosopher sums this up:
“To know is to know that you know nothing. That is the meaning of true knowledge.”
- Confucius.

The results suggest that returns from holding wine averaged 9.5% per year and compared unfavourably to stocks.

Masset, Henderson and Weisskopf (2009) made the most recent analysis on wine returns ranging data from 1996 to 2009. The data was stretched till 2009 to show that wine still is an attractive proposition in an economic downfall. Their findings suggested that over the 14-year period, wine yielded a mean rate of return (7.3%) and a low volatility (8.23%). These results showed that wine performed better than stocks. In addition, during the 2008 financial crisis, wine prices dropped by 17% while most stock indices lost half their value.
