The document discusses how investing in an equity fund can provide better returns than fixed deposits. It analyzes the historical performance of a Malaysian public index fund (PIX) over various time periods and under different rules: 1) Investing for the medium to long term (3 years or more) reduces the risk of losses and increases average returns compared to shorter periods. 2) Avoiding overpaying by only investing when the P/E ratio is below 18 improves performance over 3 and 5 year periods. 3) Not underselling when the P/E ratio is above 16 also leads to better returns. Following all three rules means there is a 0% chance of losses over 3 and 5 year periods
