The ETFRiskSharpRatio Function

The ETFRiskSharpRatio function in MarketXLS helps you quickly calculate an ETF’s Sharpe Ratio directly in Excel. This metric quantifies an ETF’s risk-adjusted returns, allowing you to easily compare multiple ETFs and evaluate their performance over specific time periods. By automating data retrieval, this function saves you time, reduces manual errors, and helps you make more informed trading or investment decisions—especially in the context of real-world US markets.

Why Use This Function?

• Evaluate Risk-Adjusted Performance
  By calculating the Sharpe Ratio, you gain insight into how much excess return you can expect per unit of risk taken on an ETF.

• Automated Data Retrieval
  No manual data downloads—MarketXLS fetches the required data automatically.

• Flexible Time Periods
  Input a custom duration to see how an ETF’s Sharpe Ratio has performed over different horizons (e.g., shorter or longer durations).

• Quick Comparisons
  Use the function across multiple ETFs in your Excel worksheet to rapidly compare and rank their risk-adjusted returns.

• Integration with Portfolio Analysis
  Combine ETFRiskSharpRatio with other MarketXLS functions to deepen analysis and create advanced portfolio strategies.

How to Use in Excel

=ETFRiskSharpRatio(Symbol, [Duration])

1. In an empty Excel cell, type “=” (equals).
2. Start typing the function name “ETFRiskSharpRatio” and let MarketXLS auto-suggest or finalize the function manually.
3. Provide the ETF ticker symbol as the first argument (e.g., "SPY").
4. Optionally, specify a duration for how many “units” of time (as determined by MarketXLS) you want to analyze. Leaving this blank defaults Duration to "3."
5. Press Enter to retrieve the Sharpe Ratio directly in Excel.

Parameters Explained

Example Usage

Basic Examples

1. Single ETF with default duration
   » In any cell, enter:
   =ETFRiskSharpRatio("SPY")
   » This fetches the Sharpe Ratio for SPY with the default duration of 3 units.

2. Single ETF with a specified duration
   » For instance, enter:
   =ETFRiskSharpRatio("QQQ", "1")
   » This looks up the Sharpe Ratio for QQQ over a time period of “1,” which you might use to focus on a shorter horizon.

3. Invalid symbol handling
   » Enter:
   =ETFRiskSharpRatio("INVALID")
   » Since the symbol is unrecognized, the function will return "NA."

Advanced Scenarios

1. Ranking ETFs by Sharpe Ratio

   • In a column, list various ETFs (e.g., SPY, QQQ, DIA, IWM).
   • Next to each symbol, call ETFRiskSharpRatio with a given duration (e.g., "3") to get risk-adjusted returns over a specific time.
   • Sort these values to see which ETF performs best on a risk-adjusted basis.

2. Combining with Other Functions

   • Use other MarketXLS metrics (like volatility, correlation, or total returns) alongside ETFRiskSharpRatio.
   • Build a multi-factor evaluation to screen ETFs for portfolio inclusion.

3. Using Duration in Strategy Testing

   • Compare the one-year Sharpe Ratio to the three-year Sharpe Ratio across multiple ETFs to see if performance consistency persists over time.
   • Filter out ETFs with a consistently low Sharpe Ratio over both short and medium durations.

Common Questions and Troubleshooting

1. “I’m getting NA. What happened?”

   • Ensure your MarketXLS license is valid. If the license is invalid, the function returns "NA."
   • Check the ETF symbol; it must be recognized and valid.

2. “Why does my result say ‘Refreshing’?”

   • MarketXLS may be fetching fresh data. The system temporarily displays “Refreshing” while adding a request to its data retrieval queue. Try again shortly.

3. “How do I change the default duration?”

   • Simply provide a Duration argument like “1,” “3,” “5,” etc. Leaving it out defaults to “3.”

4. Edge Cases & Invalid Inputs

   • An empty Duration reverts to “3.”
   • An invalid Duration returns “NA” or may revert to default.
   • Symbols that do not represent an ETF return “NA.”
