A reserve marked down a fifth straight week, with quarterly reporting due
Should the treasury rebalance the ETH reserve to a fixed allocation band now, or leave the position intact and absorb another quarter of marks?
The market facts are real; the decision maker is illustrative.
The week and the position
In the week of 9 May 2022, ETH fell 14.86% to close at 2,145.29, its fifth consecutive down week, with prior weekly returns of -6.71%, -2.24%, -3.29% and -10.80%. The week's range was 40.60% (high 2,530.78 on Monday, low 1,800.00 on Thursday), realised annualised volatility reached 175.90%, and volume ran 2.15 times its prior 12-week average. ETH stood 55.74% below its 52-week high and returned in the 10th percentile of 221 weeks of history. An illustrative treasury holds ETH as a reserve asset and reports marks quarterly.
Judgment
A reserve held for reporting cannot be timed around a single week, and this week's close sat mid-range rather than at the low, so panic selling locks in a mark that is not the week's worst. But a fifth straight down week at 175.90% realised volatility means the reserve's share of treasury assets has drifted far above any allocation set in calmer weeks. Rebalance to a stated band rather than to zero: trim only the excess above the band, keep the core reserve, and accept quarterly marks that will still show large swings. The 2.15-times volume means the trim can be executed without dominating the market.
What would change it
If a later quarter closes above the week's open of 2,519.71 or the reserve's share falls back inside the band without selling, the trim can be paused. If realised volatility keeps the band breached for two consecutive quarters, the band itself, not just the position, should be reset.
What sets this case apart
The choice is not sell or hold, but which share of a volatile reserve was ever intended: rebalancing follows an allocation rule, not a price forecast.
