Exit Decision

CLOSE – Exit threshold reached

Current performance of -4.84% has crossed the exit rule trigger at <= 3% after 10 days. The exit rules were designed to protect capital when a signal loses momentum at this critical juncture. Holding past this threshold contradicts the risk management framework that defined the trade setup. Close the position at market.

Historical Comparison

Current performance of -4.84% places this trade in the -5 to -3% range, shared by 4 historical instances of this signal. These cases consistently returned negative momentum at the 10-day mark. However, historical data shows that once a position enters this negative range, outcomes diverge significantly at longer timeframes.

The -5 to -3% range produced an average 20-day return of -2.0% and 30-day return of -0.5%, but rebounded to 2.5% by 60 days. This is not recovery worth waiting for. One trade in this exact range (1 of 4 total) experienced a stoploss hit at the -10% threshold, representing downside risk if the position stays open.

Contrast this to trades that started positively. The 3-5% range (3 instances) showed 20.3% average 60-day return, and the 5-7% range (2 instances) produced 26.7%. These patterns show that early positive momentum tends to persist; early negative momentum tends to require a stoploss. The current trajectory matches this historical warning signal.

Exit Rule Logic

The exit rule was structured with discipline: close any position showing <= 3% performance after 10 days. The data supported this rule because trades that start weak rarely recover their edge within a reasonable holding period. At -4.84%, the position has crossed that threshold by 1.84 percentage points. The rule exists to cut exposure when the signal setup has begun to fail at its most predictive window.

Capital preservation is the priority here. Holding past this rule in hopes of a 60-day recovery risks another 5.16% of capital before hitting the stoploss, based on the range history. Historical expectation for positions in this range shows an average -4.48% at entry and further deterioration expected in the next 10 days if held. The exit rule protects against compounding those losses.

Key Takeaways

The exit rule has done its job, identifying a signal that lost its early momentum. Not every trendchange signal produces immediate gains, and the exit rule is designed to identify and contain those losses early.
At -4.84%, the position is 6.84% away from the maximum stoploss, but waiting for a stoploss to trigger represents a failed risk management plan. Exiting now respects the framework that defined the trade.
Historical data on the -5 to -3% range shows that earlier exit is preferable to waiting for reversal. This range includes cases that hit the 10% stoploss, confirming that further downside risk is real.

Conclusion

The AMZN signal triggered on August 05 with a 24.03% historical edge, but that edge reflects past performance, not guaranteed future results. After 10 trading days, the position has declined 4.84%, placing it in the negative performance range. The exit rule defined at trade initiation has been triggered, and following it is the disciplined choice. Close the position. The system is working as designed; this particular signal was not.
