Definition
The K-ratio is a valuation metric that measures consistency in an equity’s returns over time. Specifically, it is derived from the value-added monthly index (VAMI) tracking the progress of an initial investment, often $1,000, in the security. By conducting a linear regression on the logarithmic cumulative return of the VAMI curve, the K-ratio provides insights into both the returns themselves and their sequence, offering a unique perspective on risk and performance.
K-Ratio vs Sortino Ratio Comparison Table
| Feature | K-Ratio | Sortino Ratio |
|---|---|---|
| Measurement Focus | Consistency of returns | Downside risk relative to target return |
| Calculation Basis | Linear regression on VAMI | Mean return vs downside deviation |
| Type of Risk Consideration | Return order | Only considers negative deviations |
| Ideal Usage | Evaluating equity performance over time | Portfolio performance analysis |
| Normalization | No specific target return | Based on a defined minimum acceptable return |
How to Calculate the K-Ratio
The K-ratio is calculated using the following formula:
\[ K = \frac{R}{T} \]
Where:
- R = Return represented through the slope of the regression line of the log(VAMI)
- T = Measure of time, capturing the chronological order of returns
Example of Calculation
If you analyze a stock whose monthly VAMI returns are log-transformed and fed into a regression analysis, let’s say we end up with a slope (R) of 0.15 over a timeline (T) of 5 years. The K-ratio would be calculated as:
\[ K = \frac{0.15}{5} = 0.03 \]
This would indicate a 3% consistent return over those 5 years!

Frequently Asked Questions
Q: Why is the K-ratio useful for investors?
A: It helps investors assess how consistently a stock has performed over time, allowing for better risk management and performance expectations.
Q: Can the K-ratio be used for all types of investments?
A: While primarily geared toward equities, the fundamental concept of measuring consistency can be tailored to other investments, but careful attention to their unique characteristics is crucial.
Q: Is a high K-ratio always better?
A: Not necessarily! It’s important to consider the context of returns and the cyclicality of an investment. Investors should never look at single metrics in isolation—after all, investing is about the whole portfolio, not just individual stocks.
