A 6.93% Saturday gain followed by a 3.63% Sunday drop tests a fixed loss limit
After Sunday's 3.63% fall triggered its fixed loss limit, should the fund re-enter at the weekly close of 58,968.31, or stay reduced until volatility and funding settle?
The market facts are real; the decision maker is illustrative.
The week and the position
In the week of 8 March 2021, BTC rose 15.72% to close at 58,968.31, 4.35% below its 52-week high, after a range of 25.51% from a Monday low of 49,274.67 to a Saturday high of 61,844.00. Saturday gained 6.93% and Sunday lost 3.63%, so the weekly close sat 77.1% of the way up the week's range. Realised volatility was 74.1% annualised, and the prior four weeks returned 25.21%, 18.17%, -21.38% and 12.93%. An illustrative fund that cuts exposure on a fixed loss limit was forced out by Sunday's drop.
Judgment
A rebound week does not erase the hit that forced the fund out, and a 74.1% volatility level means the limit can be triggered again within days. Stay reduced after the forced exit and re-enter only by a rule fixed in advance, such as a set fraction of exposure on the next weekly close, not on Sunday's drop or Monday's bounce. Accept that this leaves part of a 90th-percentile week uncaptured, and that the 0.0616% average eight-hour funding is a real cost of any long re-entry.
What would change it
If realised volatility falls materially below the 74.1% annualised level for several weeks, or the fund's written rule already permits re-entry at a stated price or weekly close, the reduced stance can be lifted. If the next week's worst day exceeds Sunday's 3.63% loss, the current limit is set too loose for this regime and should be tightened.
What sets this case apart
The loss limit fired inside a winning week; the question is re-entry discipline after a forced exit, not the direction of the market.
