The listing of Bitcoin ETFs now allows BTC to be more conveniently included as an allocation in fund managers' asset portfolios. Wall Street fund managers will soon realize that BTC can serve as a highly effective alpha factor. By adding a small amount to their portfolios, they can significantly enhance the Sharpe ratio of the entire asset portfolio.
The Sharpe ratio, also known as the Sharpe index or Sharpe value, measures in the financial field how well an investment (such as a security or portfolio) performs relative to the risk adjusted to it, compared to the performance of a risk-free asset. It is defined as the expected value of the difference between investment returns and risk-free returns, divided by the investment standard deviation (i.e., its volatility).
As is widely known, returns are directly proportional to risk. However, taking an equal amount of risk, some investments can yield substantial returns, while others may be less satisfactory. In simple terms, the return per unit of risk taken is the Sharpe ratio. This metric describes whether a risky investment is worth undertaking. |
