According to Foresight News, diversification has always been a key strategy for reducing risk and increasing returns in the rapidly evolving investment world. With the emergence of cryptocurrencies, particularly Bitcoin, investors have found a new asset class to include in their portfolios. This article delves into the impact of incorporating Bitcoin into traditional 60/40 stock and bond portfolios.
By analyzing various digital indicators, we explore how different levels of Bitcoin allocation affect the overall performance, risk, and return rate of the portfolio. From gradually increasing positions to incorporating large amounts into the portfolio, we reveal the subtle relationship between risk and return in the context of Bitcoin investment.
The leftmost column in the figure below shows the situation when no Bitcoin is allocated in the portfolio, and the following columns show what happens when Bitcoin holdings are gradually increased (up to 10%). These lines do not represent changes over time, but rather how much Bitcoin you hold. Interestingly, from a historical perspective, the more Bitcoin you allocate, the higher the return rate.
Although adding Bitcoin to a 60/40 stock and bond portfolio increases cumulative returns, there is a problem: it may also increase uncertainty and risk. Figure 2 shows the change in volatility after allocating Bitcoin. While the risk increases, it is not a linear rise. Instead, there is a curvature to the line. This means that if you only add a small amount of Bitcoin, such as between 0.5% and 2%, it will not increase your investment risk too much. However, as you add more Bitcoin, things can quickly become unpredictable.
In Figure 3, we combine the information from Figure 1 to examine the Sharpe ratio of the portfolio. The shape of the graph is very interesting: it rises rapidly at first, then levels off as you invest more Bitcoin. This chart indicates that when you add some Bitcoin to your investment, it usually means you will get more returns to compensate for the risk you take. However, there is no free lunch: once you start adding more and more Bitcoin, especially after about 5% of the total investment, the increase in risk becomes more apparent than the benefits. Therefore, allocating a small amount of Bitcoin may help, but beyond a certain point, the cost of allocating more Bitcoin is a significant increase in risk. Based on historical returns and mean-variance optimization, the optimal proportion of Bitcoin to add to the portfolio is between 3% and 5%.
In conclusion, exploring Bitcoin as part of a diversified investment portfolio reveals the delicate balance between risk and return. The results presented through various data emphasize the potential to increase cumulative returns by strategically increasing Bitcoin holdings, accompanied by an increase in volatility. According to historical data and mean-variance optimization, the best strategy is to allocate 3% to 5% of total investment to Bitcoin.
