4. SOPR & Adjusted SOPR: Tracking Seller Profit Realization in Real Time

Part of Chapter 04: On-Chain Valuation & Market Cycle Metrics

Core Learning Concepts
  • SOPR = Realized Value / Value at Creation
  • SOPR = 1.0 as the critical neutral break-even pivot
  • Adjusted SOPR (aSOPR): Filtering out noise from intra-day UTXO churn

While NUPL tracks paper (unrealized) profits, the Spent Output Profit Ratio (SOPR) tracks actual realized profit and loss from coins that are actively moving on-chain.

A SOPR value greater than 1 indicates that coins moved that day were sold at a profit. A value below 1 indicates coins were sold at a loss.

In a healthy bull market, dips down to SOPR = 1.0 act as formidable support. Investors refuse to sell their coins at a loss and buy the dip at their break-even level. If SOPR breaks cleanly below 1.0 and gets rejected from below on retests, a bear market has begun.

Quantitative Formula: SOPR Calculation
LaTeX Specification
\text{SOPR} = \frac{P_{\text{spent}}}{P_{\text{created}}}

Mathematical Explanation: A value of exactly 1.0 represents aggregate breakeven. Bull market pullbacks consistently bounce at SOPR 1.0.

Institutional Execution Insight

Use a 7-day or 14-day moving average of aSOPR on your daily charts. Bullish resets where aSOPR touches 1.0 and bounces provide optimal low-risk swing long entry triggers.
