Week of 16 September 2024: Bitcoin and Ether rise 7.5% and 11.4% on below-average volume
When two assets post near-top-percentile weekly gains on lighter-than-usual volume, what does the price record establish, and what should a desk verify before reading it as a trend change?
BTC rose from 59,132.00 to 63,578.76 (+7.52%) and ETH from 2,316.09 to 2,581.00 (+11.44%), both closing in the upper third of their week ranges. Dollar volume was below prior twelve-week averages for both (0.88x BTC, 0.74x ETH). Funding averaged near flat, at 0.0049% and 0.0051% per eight hours.
What the data shows. BTC opened the week at 59,132.00 on Monday 16 September, set its low of 57,493.30 at 17:00 UTC that same day, then reached its high of 64,133.32 at 04:00 UTC on Friday 20 September. It closed at 63,578.76, in the upper third of the week range. ETH followed the same order — low before high — with a low of 2,252.39 at 02:00 UTC Monday and a high of 2,632.57 at 00:00 UTC Sunday 22 September, closing at 2,581.00. The best days were Tuesday 17 September for BTC (+3.61%) and Friday 20 September for ETH (+3.90%). Weekly returns ranked at the 80th percentile for BTC and 83rd for ETH across 344 recorded weeks. Dollar volume totalled 10.90 billion for BTC and 4.69 billion for ETH, which is 0.88 and 0.74 times their prior twelve-week averages.
What it does not show. A strong close on lighter volume can reflect conviction or simply fewer participants; the candles record only the trades that occurred. The data does not identify who was buying, or whether the move came from a few large orders. It also cannot say whether the close near the weekly high marks a change in trend.
What a careful desk would check. Realised volatility — the size of the swings that actually happened, scaled to a yearly figure — was 44.4% for BTC and 52.8% for ETH, with largest hourly moves of 2.20% and 2.62%. At the close BTC remained 13.59% below its 52-week high and ETH 36.55% below. A desk would read the percentile rank against the volume reading rather than alone, and would compare the week's 11.55% BTC range (16.88% for ETH) with what its limits assume.
Ether against Bitcoin. Both moved in the same direction, but ETH gained 3.92 percentage points more, lifting the ETH/BTC ratio 3.64%. Hourly correlation was 0.81 — close, though not locked together. The four prior weeks were evenly split, two up and two down for each asset.
Funding. BTC perpetual funding averaged 0.0049% per eight hours (high 0.01%, low -0.0005%); ETH averaged 0.0051% (high 0.01%, low -0.0069%). Rates near zero mean longs and shorts exchanged very little; the data shows the payment levels only, not the size of the positions behind them.
What would change this reading
- If BTC trades above its weekly high of 64,133.32 in a later week while volume exceeds its prior twelve-week average, the below-average participation reading weakens.
- If ETH closes a later week back below its open of 2,316.09, the 11.44% gain reads more like a range swing than a sustained shift.
- If the ETH/BTC ratio falls after rising 3.64% in a week when both assets gained, the outperformance was short-lived rather than structural.
- If funding for either asset moves well above its 0.01% eight-hour high while price stalls, the cost of holding longs becomes the binding constraint.
Terms
- realised volatility
- how much the price actually swung over a period, expressed as a yearly percentage
- close location
- where the closing price fell within the week's high-to-low range; upper third means it finished near the top
- percentile
- the share of past weeks with a lower value; the 80th percentile means 80% of the 344 recorded weeks were lower
