Risk-Adjusted Performance Grade Moderate Alpha (High Volatility)

Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Sharpe Ratio = (Expected Return - Risk-Free Rate) / Portfolio Volatility (σ)

Step-by-Step Mathematical Derivation

1
Excess Return Over Cash

Excess Return = 42.0% - 4.5% Risk-Free = 37.5%.

2
Sharpe Ratio Formulation

Sharpe Ratio = 37.5% / 55.0% = 0.6818. A Sharpe ratio below 1.0 indicates returns are heavily driven by sheer market volatility rather than genuine alpha.

3
Daily Parametric Value at Risk (VaR 95%)

Daily Volatility = 55% / √365 = 2.879%. At 95% confidence (Z = 1.645): Daily VaR = 1.645 × 2.879% × $100,000 = $4,736.00.

4
Downside Tail Risk

On 95 out of 100 days, daily portfolio loss will not exceed $4,736. On the remaining 5 days, losses may be substantially higher.

Frequently Asked Questions

What is considered a good Sharpe Ratio in crypto? +
A Sharpe ratio above 1.0 is considered good; above 2.0 is very good; above 3.0 is elite. Many buy-and-hold crypto portfolios exhibit Sharpe ratios between 0.6 and 1.1 due to severe 70%+ drawdowns.
Why is the Sortino Ratio often preferred over the Sharpe Ratio for crypto? +
The Sharpe Ratio penalizes upside volatility equally alongside downside crashes. The Sortino Ratio penalizes only downside volatility, giving a fairer score to asymmetric assets like Bitcoin.
