One row per year, 52 week slots straight across, grouped under the month they belong to. Cells are whole percent — hover one for the exact figure.
This page lays Ethereum (ETH)'s history out one row per year, 52 week slots straight across, grouped under the month they belong to. Ethereum's signature months were rarely built evenly — DeFi-summer and 2021 bursts often packed a month's move into one or two week slots. The 52-slot strip shows exactly where inside each month those runs happened, something the monthly grid compresses away.
A week's return is its last daily close against the last close of the previous slot — fixed chunks of calendar days, not ISO weeks, so columns align across years. ETH's data starts at its perpetual listing in November 2019. That window frames Ethereum's modern era — DeFi summer 2020, the 2021 double-peak, the 2022 unwind and the ETF-era regime after it.
Ethereum is down 2.5% so far in week 41 (October) of 2026, from the last daily close of the previous week slot to the close of 10 October 2026 (UTC). Coinfuty's weekly grid uses 52 fixed slots per year (5, 4 and 4 per quarter month), so this cell keeps moving until the slot ends.
Ethereum returned −4.2% in week 40 (October) of 2026, its most recent completed week slot. The median return for that week slot on record is −2.6%.
Of the 40 completed week slots of 2026, Ethereum's strongest was week 34 (August) at +32.4% and its weakest week 23 (June) at −15.8%. 17 of 40 closed positive. The current slot is excluded until it ends.
Across 11 prior years on record, the median return for week 41 (October) is −0.3% for Ethereum. The best was 2020 at +11.6% and the worst 2018 at −11.6%; 5 of 11 closed positive.
Across 581 completed week slots on record, Ethereum's best week was week 11 (March) 2017 at +178.3% and its worst week 32 (August) 2015 at −73.4%. 295 of 581 weeks (51%) closed positive.
Resolution on how months were won. Many of Ethereum's strongest months concentrated their gain into a week or two, and the weekly strip separates those burst months from ones that ground higher day after day.
ETH's history here begins at its first daily perpetual-futures candle on Binance in November 2019. Week slots start with the first complete slot after the listing, and dashed cells mark slots before it — pre-listing history is not backfilled.
The last daily close of the week slot divided by the last close of the previous slot, minus one, in USD on UTC boundaries. Slots are equal chunks of calendar days within each month, not ISO weeks, so columns align across years.
