- September historically underperforms with an average -10.5% return for Ethereum.
- October signals a potential rebound, averaging +7.00% historically.
- Q4 and Q1 emerge as strong quarters for altcoin growth.
Ethereum Investors Eye Seasonal Patterns
The crypto market braces for the final stretch of 2025, Ethereum (ETH) investors are eyeing historical patterns to navigate the volatile landscape. A recent post by crypto analyst Michaël van de Poppe on X, featuring a detailed chart of Ethereum’s monthly returns (USD) from 2015 to 2025, highlights a recurring trend: September and October often mark a pivotal shift. The data reveals September as a historically weak month, with an average return of -10.5% and a median of -12.7%, aligning with this year’s -8.54% drop as of late September 2025. This “Redtember” effect, as dubbed by the community, suggests a seasonal correction that shakes out weaker hands.
October Brings “Greentober” Optimism
However, the outlook brightens in Q4. The chart shows October averaging a +7.00% return, with notable gains in years like 2021 (+42.8%) and 2020 (+7.7%). This “Greentober” phenomenon, coupled with strong Q1 performances, positions the year-end as a potential playground for altcoins, including ETH. Van de Poppe’s analysis reinforces this, noting that Q4 and Q1 historically favor altcoin rallies, offering hope after September’s downturn.
Can History Repeat for Ethereum Bulls?
The data also underscores Ethereum’s resilience. Despite a challenging 2025 so far—marked by a -32.2% plunge in February and a -18.4% dip in March—positive months like May (+41.1%) and July (+48.7%) show its capacity for recovery. As we approach October 2025, investors are poised to capitalize on this seasonal uptick, though macro factors and market sentiment will play a crucial role.With Ethereum’s historical patterns in focus, the coming months could redefine its trajectory. Whether this cycle follows suit or breaks tradition remains to be seen, but the data offers a compelling case for optimism.
