The Mayer Multiple is current price divided by the 200-day moving average. Below 1.0, Bitcoin has historically traded at a discount to its own trend — a favourable long-term zone. Above 2.4, it has historically been overheated. One of the simplest, longest-standing indicators in Bitcoin analysis.
What Is the Mayer Multiple?
The Mayer Multiple is one of the oldest Bitcoin technical indicators still in wide use — introduced by investor and Bitcoin advocate Trace Mayer back in 2011, when the asset was still trading for single-digit dollars. It compares current price to a smoothed measure of its own recent trend, giving a simple read on whether price is running hot or cold relative to where it's been.
The Formula
That's the entire calculation. A reading of 1.0 means price is exactly at its 200-day average. Above 1.0 means price is running above trend; below 1.0 means it's running below trend. The 200-day window was chosen because it's long enough to smooth out short-term noise while still being responsive to genuine multi-month trend shifts — a reasonable middle ground between something like the fast-moving 50-day average and the very slow 200-week average.
Why Simplicity Works Here
It would be easy to assume a more complex model — incorporating on-chain data, power-law regressions, or multi-factor scoring — would outperform something this simple. In practice, the Mayer Multiple's specific thresholds have held up remarkably well across more than a decade of Bitcoin cycles, which says something genuine about how consistently Bitcoin's price has mean-reverted toward its own 200-day trend, cycle after cycle. Simplicity is also a real advantage in its own right: there's no hidden calibration or subjective parameter choice to second-guess.
Reading the Zones
| Mayer Multiple | Zone | Historical Interpretation |
|---|---|---|
| Below 1.0 | Deep Value | Trading below its 200-day average — one of Bitcoin's more attractive long-term accumulation zones historically |
| 1.0 – 2.4 | Fair Value | Within broad historical range, no extreme signal |
| Above 2.4 | High Risk | Far above its 200-day average — historically uncommon, often overheated conditions |

Limitations
It's purely price-based. Like the Bull Market Support Band and 200-week MA, it says nothing about holder behaviour, on-chain fundamentals, or valuation relative to network activity — only price relative to its own recent trend.
Thresholds are historically calibrated, not fixed constants. The 1.0 and 2.4 boundaries reflect where past extremes have landed — a useful reference, not a guarantee for future cycles as Bitcoin's volatility profile continues to mature and compress.
200 days is a specific, somewhat arbitrary window. A different averaging window would produce a related but not identical signal — there's nothing uniquely "correct" about 200 days beyond its long track record of usefulness.
How to Use It
The Mayer Multiple works well as a quick, no-fuss trend check alongside more data-intensive indicators. Use it alongside AHR999 and the Fear & Greed Index for broader context — when several independent indicators point to similar conditions, the combined signal is usually more useful than any single metric on its own.
It's also one of the 21 inputs to our Cycle Compass composite score.
