SOPR Short-Term Holders
Spent Output Profit Ratio restricted to coins held less than 155 days. When STH-SOPR drops below 1.0, recent buyers are capitulating - historically a local-bottom indicator.
What is it?
STH-SOPR calculates the profit/loss ratio only for spent UTXOs with a lifespan under 155 days. It captures the selling behaviour of the market's most recent and reactive participants. Since these holders are statistically the most price-sensitive, their STH-SOPR is a particularly sensitive indicator of short-term sentiment and propensity for panic or euphoria.
How to read
Like Classic SOPR, the pivot is at 1. However, STH-SOPR oscillates with greater amplitude as short-term holders are more volatile in behaviour. In a bull market, brief STH-SOPR dips below 1 (STH selling at a loss) have historically coincided with local price troughs. This does not constitute a timing indicator. Prolonged dips below 0.95 mark significant weak-hand stress.
Key zones
STH-SOPR > 1.02: active STH profit-taking. STH-SOPR = 1: decision point - support in bull, resistance in bear. STH-SOPR < 0.95: STH capitulation, selling at significant losses. STH-SOPR < 0.85: extreme panic, historically reliable local bottom indications in bull markets.
What to observe
STH-SOPR is the best indicator for detecting 'wash-outs' (local weak-hand capitulations in bull markets). When STH-SOPR briefly dips below 0.9 then quickly recovers above 1, this has historically marked local bottoms. The combination STH-SOPR < 0.9 + STH-MVRV < 0.9 has been a particularly reliable local capitulation indication.
Historical context
STH-SOPR reached extreme troughs during each 20%+ bull market correction: -20% in September 2020 (STH-SOPR 0.88), -25% in January 2021 (0.85), -53% in May 2021 (0.75). In the 2022 bear market, STH-SOPR remained below 1 for extended periods (May-July, October-December), marking persistent weak-hand capitulation.
Expert notes
STH-SOPR can be combined with funding rate data to distinguish spot capitulations from leveraged capitulations. When STH-SOPR < 1 AND funding rates are negative, capitulation is amplified by liquidations - potentially more reliable bottom indication. The SOPR Explorer (tool #134) allows customising the age threshold beyond the 155-day convention.
Common mistakes to avoid
A persistent STH-SOPR < 1 does not mean ALL STH are selling at a loss every day. It is a weighted average - some STH sell at a profit while others sell at a loss, and the net balance is negative. Large tickets (high-volume transactions) can dominate the average and create distortions.
