Age 15Explain it to a 15-year-oldConnect it to the formula
Upside capture compares portfolio and benchmark performance during benchmark-up periods. This page evaluates the relationship directly. The rule is c=a/b. Its input values are portfolio compounded return in benchmark-up periods, benchmark compounded return in up periods, and the main result is upside capture ratio. For example: portfolio compounded return in benchmark-up periods=0.12 and benchmark compounded return in up periods=0.1 produce upside capture ratio=1.2.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated upside market capture ratio relation over the valid real-number domain stated below. The implemented relation is c=a/b, evaluated from portfolio compounded return in benchmark-up periods, benchmark compounded return in up periods to produce upside capture ratio. Upside capture compares portfolio and benchmark performance during benchmark-up periods. This page evaluates the relationship directly. Use the same periods and compounding convention for both returns.
Inputs and valid domain
- portfolio compounded return in benchmark-up periods must be a finite real number.
- benchmark compounded return in up periods must be a finite real number.
Important boundary: Use the same periods and compounding convention for both returns.
The formula
c=a/b
How the calculator works through it
It substitutes portfolio compounded return in benchmark-up periods, benchmark compounded return in up periods into the formula and exposes every numerical step above. The main output is upside capture ratio.
Read the result correctly
The upside capture ratio is the direct answer to “calculate upside capture ratio from portfolio compounded return in benchmark-up periods and benchmark compounded return in up periods.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
portfolio compounded return in benchmark-up periods=0.12 and benchmark compounded return in up periods=0.1 produce upside capture ratio=1.2.
Where this model stops being reliable
Use the same periods and compounding convention for both returns.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
