What is the Mayer Multiple?
The Mayer Multiple is Bitcoin's price divided by its 200-day simple moving average. It is named after investor Trace Mayer, who popularized it. A reading of 1.0 means price equals its 200-day average. A reading of 2.0 means price is twice that average. The idea is simple: when price is far above its long-run trend, it may be stretched, and when it is below, it may be depressed.
How SellSignal calculates it
SellSignal divides the latest daily close by the average of the last 200 daily closes. It is warm at 2.0 or higher and hot at 2.4 or higher, where 2.4 is the level traditionally quoted as the classic Mayer top level. For the composite score, the heat value is 0 at 1.0× and rises linearly to 100 at 2.4×, and readings below 1.0× count as 0. The Mayer Multiple is one of six equally weighted indicators, so it contributes one sixth of the overall score.
As of 2026-10-15, the multiple is 1.13× (status: cool, heat 9 out of 100).
What happened at past Bitcoin peaks
| Window | Peak close | Multiple at peak close | Highest multiple in window |

| 2013-14 | 2013-12-05 | 5.65× | 6.38× |
| 2017-18 | 2017-12-17 | 3.72× | 3.72× |
| 2021 | 2021-11-09 | 1.48× | 2.45× |
| 2024-26 | 2025-10-07 | 1.18× | 1.85× |
Computed by SellSignal's own code from blockchain.info daily BTC/USD data, using the same formulas as the dashboard. "Peak" means the highest daily close in each window: Oct 2013 to Feb 2014, Oct 2017 to Jan 2018, Mar to Dec 2021, and Jan 2024 to Oct 15, 2026. Early (2013) prices come from a thin, fragmented market, so treat those rows as rough.
In this data the 2.4 line was exceeded in the 2013, 2017 and 2021 windows, but not in the 2024-26 window, whose highest reading was 1.85. Notably, the 2021 reading above 2.4 came earlier in the year, well before the November 2021 closing high, when the multiple was only 1.48. Each cycle's high has been lower than the one before it.
Limits and caveats
- Only three or four cycles of data exist, so any threshold is a convention, not a law.
- The shrinking peaks may reflect a bigger, more mature market, or they may not. A fixed 2.4 line would have missed the latest peak entirely.
- A moving average is backward-looking. A low Mayer Multiple does not mean price cannot fall, and a high one does not mean it must.

Frequently asked questions
What is a good Mayer Multiple for Bitcoin?
There is no universally good value. Readings near or below 1.0 mean price is near or under its 200-day average, and readings of 2.4 or more have been treated as the classic overheated level. SellSignal flags warm at 2.0 and hot at 2.4.
How is the Mayer Multiple calculated?
Divide Bitcoin's price by its 200-day simple moving average. SellSignal uses the latest daily close and the average of the previous 200 daily closes.
Does the Mayer Multiple predict Bitcoin tops?
Not reliably. In the data SellSignal uses, the multiple was far above 2.4 near the 2013 and 2017 peaks, but it peaked at 1.48 at the November 2021 closing high and 1.18 at the October 2025 closing high.
Who invented the Mayer Multiple?
It is named after Trace Mayer, who popularized the ratio.
