Direct Answer
The level of a growth style index divided by the level of the corresponding value style index, such as the Russell 1000 Growth over the Russell 1000 Value. A rising ratio means growth stocks are outperforming value stocks. A rising ratio shows leadership by growth stocks and a falling one leadership by value stocks.
Growth vs Value Ratio: Formula, Meaning, Signals, Examples and How to Use It
How Is Growth vs Value Ratio Calculated?
The level of a growth style index divided by the level of the corresponding value style index, such as the Russell 1000 Growth over the Russell 1000 Value. A rising ratio means growth stocks are outperforming value stocks.
Formula: Ratio = growth index level / value index level
Inputs:
- Growth style index or ETF price
- Value style index or ETF price
- Same dates for both
Worked example. If a growth fund trades at 312.50 and a value fund at 148.20, the ratio is 2.109. The inputs are illustrative numbers, not market data.
Reading it. A rising ratio shows leadership by growth stocks and a falling one leadership by value stocks. The trend of the ratio, often compared with its moving average, shows which style is in favour, and the changes often coincide with moves in interest rates.
Limits. Growth and value index rules differ by provider and are rebalanced periodically, so a stock can switch sides. Very large companies can dominate one side.
What is Growth vs Value Ratio?

How to use Growth vs Value Ratio
A rising ratio shows leadership by growth stocks and a falling one leadership by value stocks. The trend of the ratio, often compared with its moving average, shows which style is in favour, and the changes often coincide with moves in interest rates. A reading alone is never a buy or sell signal; it needs context from price structure, volume, volatility and the broader market regime.
Strengths
- Both legs come from one index family and universe split by style rules, so the ratio contrasts two halves of a single market.
- One line summarizes which style has led over any chosen window, from a quarter to a decade, without recalculating a return gap.
- Reproducible when the formula and data convention are fixed.
Weaknesses and limitations
- Sector tilt is built in: growth indexes lean toward technology and value indexes toward financials, so the ratio partly tracks sector performance.
- A price-only ratio omits the larger payouts typical of value stocks, so total-return series are needed for a full comparison.
- Correlated indicators can create false confidence by repeating the same underlying information.

Frequently Asked Questions
Is Growth vs Value Ratio a buy or sell signal?
No. A rising ratio shows leadership by growth stocks and a falling one leadership by value stocks. Growth and value index rules differ by provider and are rebalanced periodically, so a stock can switch sides. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions.
What is the best setting for Growth vs Value Ratio?
Growth vs Value Ratio is computed from growth style index or ETF price; value style index or ETF price; same dates for both, so the choices that matter are the data convention and the window it is read over. Test those across instruments, regimes and out-of-sample periods instead of fitting one historical winner.
Can Growth vs Value Ratio be used by itself?
Growth and value index rules differ by provider and are rebalanced periodically, so a stock can switch sides. Very large companies can dominate one side. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone.
Does Growth vs Value Ratio work on every timeframe?
The calculation (Ratio = growth index level / value index level) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it.
Why does Growth vs Value Ratio give false signals?
Sector tilt is built in: growth indexes lean toward technology and value indexes toward financials, so the ratio partly tracks sector performance. A price-only ratio omits the larger payouts typical of value stocks, so total-return series are needed for a full comparison. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated.
How should Growth vs Value Ratio be backtested?
Rebuild Growth vs Value Ratio from growth style index or ETF price using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
