Investors often ask a simple but powerful question:
Is Asset A outperforming Asset B?
The answer isn’t found by looking at two separate charts. It’s found by using an asset price ratio.
An asset price ratio compares the price of one asset (the primary asset) to another (the base asset) to measure relative performance over time. Instead of asking whether both assets are going up or down, you’re asking:
Which one is winning?
This type of analysis is essential for portfolio allocation, sector rotation, risk management, and identifying market leadership.
In this guide, you’ll learn:
  • What an asset price ratio is
  • How a price ratio chart works
  • How to interpret relative strength
  • Real-world examples (Gold vs S&P 500, Stock vs Bitcoin)
  • How to use moving averages in ratio analysis
  • When to apply ratio analysis in your strategy

What Is an Asset Price Ratio?

An asset price ratio is calculated by dividing the price of one asset by the price of another.
Formula:
Price Ratio = Primary Asset Price ÷ Base Asset Price
For example:
  • GLD (Gold ETF) price = $180
  • S&P 500 Index = 6,000
Ratio = 180 ÷ 6,000 = 0.03
This number by itself isn’t important. What matters is how it changes over time.
  • If the ratio rises → Gold is outperforming the S&P 500
  • If the ratio falls → Gold is underperforming
This transforms your perspective from absolute returns to relative performance.

Why Asset Ratio Analysis Matters

Most investors focus only on price direction.
That’s incomplete.
If two assets both rise 10%, but one rises 20% and the other rises 5%, capital should logically flow toward the stronger performer.
Asset ratio analysis helps you:
  • Identify market leaders
  • Spot sector rotation
  • Compare stocks vs indices
  • Analyze defensive vs risk-on assets
  • Build relative strength strategies
  • Optimize portfolio allocation
Professional fund managers rely heavily on ratio charts for this reason.

What Is a Price Ratio Chart?

A price ratio chart plots the historical ratio between two assets over time.
Instead of viewing two separate charts, you see a single line representing their relationship.
For example:
  • Gold vs S&P 500
  • Apple vs Nasdaq
  • Bitcoin vs QQQ
  • Energy sector vs Technology sector
When the chart trends upward, the primary asset is gaining relative strength.
When it trends downward, it is losing strength.
This gives a clean visual signal for capital rotation.

Example 1: Gold vs S&P 500 Ratio

The gold-to-S&P 500 ratio is one of the most widely watched macro indicators.
When the ratio rises:
  • Investors prefer safety (gold)
  • Risk appetite declines
  • Equity markets may be under pressure
When the ratio falls:
  • Stocks are outperforming
  • Risk appetite is strong
  • Bull markets often dominate
Instead of guessing whether gold or stocks are better, the ratio tells you clearly.

Example 2: Stock vs Index Comparison

Suppose you want to know whether Apple is outperforming the Nasdaq.
Looking at two charts can be misleading.
Instead, divide:
AAPL ÷ QQQ
If the ratio trends higher, Apple is beating the index.
If it trends lower, Apple is lagging.
This helps you:
  • Identify true market leaders
  • Avoid weak stocks in strong markets
  • Allocate capital to outperformers

Relative Strength vs Asset Price Ratio

These terms are often confused.
Relative Strength (RS) measures performance versus a benchmark.
Asset Price Ratio is the mathematical foundation behind that measurement.
The ratio chart is the raw data.
Relative strength is the interpretation.
Important:
This is different from RSI (Relative Strength Index), which measures momentum on a single asset.
Ratio analysis compares two different assets.

Using Moving Averages in Ratio Analysis

One of the most powerful techniques is applying moving averages to a ratio chart.
Common settings:
  • EMA 50 (medium-term trend)
  • EMA 200 (long-term trend)
How to interpret:
  • Ratio above EMA 50 and EMA 200 → Strong relative uptrend
  • Ratio below both → Relative weakness
  • EMA 50 crossing above EMA 200 → Bullish relative shift
  • EMA 50 crossing below EMA 200 → Bearish relative shift
This helps filter noise and identify trend changes in leadership.

How Portfolio Managers Use Asset Ratios

Institutional investors use ratio charts for:

1. Sector Rotation

Comparing:
  • Technology vs Financials
  • Growth vs Value
  • Small Caps vs Large Caps
Whichever ratio trends higher receives more allocation.

2. Risk-On vs Risk-Off Analysis

Comparing:
  • Stocks vs Gold
  • Stocks vs Bonds
  • High-beta vs Low-beta assets
This helps assess market sentiment.

3. Crypto vs Equity Markets

Bitcoin vs Nasdaq ratio shows whether capital is rotating into speculative assets.
When BTC outperforms equities, risk appetite is expanding.

4. Pair Trading Strategies

Advanced traders use ratios to:
  • Identify divergences
  • Trade spread reversals
  • Hedge correlated assets

When Should You Use Asset Price Ratio Analysis?

Use it when:
  • Choosing between two investment options
  • Comparing stock vs ETF
  • Evaluating sector strength
  • Allocating capital dynamically
  • Managing multi-asset portfolios
Avoid using it when:
  • Comparing assets with completely different volatility profiles without context
  • Ignoring fundamental drivers
Ratio analysis is a decision tool - not a prediction engine.

Common Mistakes in Ratio Analysis

1. Ignoring Trend Context

Short-term spikes don’t equal structural leadership.

2. Comparing Unrelated Assets

Gold vs a micro-cap stock may not provide meaningful signals.

3. Overreacting to Small Fluctuations

Zoom out to see the macro trend.

4. Confusing RSI with Relative Strength

They measure entirely different things.

Asset Types You Can Compare

A proper asset price ratio tool should support:
  • Stocks
  • ETFs
  • Indices
  • Crypto
  • Forex pairs
  • Commodities
This allows for multi-asset macro analysis.
Examples:
  • SPY vs QQQ
  • GLD vs GSPC
  • BTC vs Nasdaq
  • EURUSD vs DXY
  • Energy ETF vs S&P 500

How to Compare Two Assets Step by Step

  1. Go to the Investorean’s Asset Price Ratio tool
  1. Select your primary asset.
  1. Choose your base asset.
  1. Generate the price ratio chart.
  1. Add moving averages (EMA 50 & EMA 200).
  1. Identify trend direction.
  1. Confirm using performance metrics.
  1. Adjust allocation accordingly.
This process removes guesswork and adds structure.

Why Asset Ratio Analysis Is Superior to Absolute Returns

Absolute returns answer:
“Did this asset go up?”
Relative analysis answers:
“Did this asset outperform alternatives?”
Capital naturally flows toward relative strength.
Understanding that flow gives you an edge.

Summary

The asset price ratio is one of the most underutilized but powerful tools in investment analysis.
It helps you:
  • Identify outperformers
  • Detect market rotation
  • Improve allocation decisions
  • Trade leadership shifts
  • Reduce emotional bias
If you want to make smarter allocation decisions, you need to stop looking at isolated charts and start analyzing relationships between assets.
Because in markets, performance is always relative.
