Why Gold Deserves a Spot in Your Portfolio: Enhancing Diversification Beyond All Country and S&P 500
[In JPY Terms] Trends in the Base Price of Gold and the S&P 500
We will examine the trends in the base prices of the Gold Fund and the S&P 500 Index Fund.
For the Gold Fund, we have selected the “Gold Fund (No Currency Hedge)” [Trust Fee: 0.407% per year], which has a relatively long track record. Its inception date is July 31, 2017.
For the S&P 500 Index Fund, we have chosen the “iShares U.S. Equity (S&P 500) Index Fund” [Trust Fee: 0.0938% per year], which was launched on September 3, 2013.
The following data is indexed to “100” as of July 31, 2017.

Both funds are influenced by USD/JPY exchange rate fluctuations, resulting in similar price movements. However, when observing the circled areas, we can see that they exhibit opposite trends. During stock market downturns, gold prices either rise or remain stable. Holding a 50/50 allocation helps smooth out fluctuations while maintaining an upward trajectory.
Stocks are essential for long-term wealth accumulation, but incorporating gold into your portfolio can enhance resilience against market crashes while boosting returns.
