Strategy Analysis
Strategy observation — period highlight
Momentum dominates by volume (+14.61% aggregate PnL) but its 36.8% win rate masks a barbell distribution: big winners (TSM +6.35%, MS +5.33%) paired with energy losers (COP, TTE) and a cluster of breakevens. Breakout has the highest WR (42.9%) but negative aggregate PnL due to asymmetric loss sizing on COST. Key insight: trailing stops are working aggressively — 40% of resolved signals hit breakeven, meaning capital preservation is excellent but profit capture is being left on the table. The VWAP gate may be too conservative on gap-up sessions (RISK-ON 85).
Regime Analysis
Regime lesson of the period
The regime oscillation from RISK-ON 45 to EARLY RISK-OFF 40 to RISK-ON 85 within 8 sessions is the defining feature. Three key takeaways: (1) EARLY RISK-OFF destroyed energy exposure but rewarded quality mega-caps — sector selection matters more than regime label. (2) High-confidence RISK-ON 85 paradoxically generated mostly breakevens — entries were too late (gap-up effect). (3) The regime confidence should inform entry timing, not just sizing — in RISK-ON 85, wait for intraday pullback before entry rather than chasing the open.
Top 3 Setups
TSM — Taiwan Semiconductor (+6.35% expired)
TSM was a quality mega-cap momentum play entered during EARLY RISK-OFF — counterintuitive but correct. The thesis: AI semiconductor capex cycle is structurally independent of short-term regime shifts. TSM held through the RISK-ON transition and expired at +6.35%, validating the "quality survives regime oscillation" principle. This is the archetype of a setup that works across regimes because the fundamental driver (AI demand) transcends macro noise. Key takeaway: in regime oscillation periods, lean into secular trend mega-caps rather than cyclical plays.
MS — Morgan Stanley (+5.33% expired)
MS capitalized on the bank momentum thesis from the week's opening RISK-ON scan. With 30Y yields supporting NIM expansion and M&A pipeline activity, the financials momentum was well-timed. MS held through the mid-week EARLY RISK-OFF dip (unlike COP/TTE which stopped out) because bank stocks have lower beta to oil-driven risk-off events. The +5.33% return on expiry demonstrates that sector-regime alignment is the primary driver: financials in RISK-ON is the canonical match.
ARM — Arm Holdings (+4.22% trailing)
ARM continues its run from the previous retro (was +6.35% inflight last week). Now resolved at +4.22% on trailing — the trailing stop locked in profits during the regime transition. This is the second consecutive retro where ARM appears in the Top 3, confirming that AI semiconductor breakouts have structural momentum that persists beyond individual scan windows. The IP royalties + AI accelerator thesis remains intact. Trailing stop at +4.22% is conservative given the move, but capital preservation in volatile regimes is the priority.
Flop 3 Setups
COP — ConocoPhillips (-3.51% stopped)
COP was a momentum play in EARLY RISK-OFF — fundamentally misaligned. Oil crashed -4.78% on May 27, and the energy sector rotation was already visible by May 20. The scanner identified COP's technical setup (above EMA20, strong volume) but failed to weigh the macro headwind: EARLY RISK-OFF + energy = toxic combination. The stop was appropriate but the entry should never have been taken. Actionable rule: block energy momentum signals when regime = EARLY RISK-OFF. This rule would have saved COP (-3.51%) and TTE (-2.47%) — combined -5.98% of avoidable losses.
COST — Costco (-3.01% stopped)
COST was a 52W high breakout at the exact wrong moment — EARLY RISK-OFF is structurally hostile to breakout strategies because institutional buyers step back and liquidity thins. The stop was tight but appropriate given the regime; the problem was taking the trade at all. Breakout in EARLY RISK-OFF has now produced stops in 2 consecutive retros (COST here, similar pattern last week). Actionable rule: suppress breakout entries when regime confidence in EARLY RISK-OFF > 40%. Breakout strategy should only run in RISK-ON or RECOVERY.
TTE — TotalEnergies (-2.47% stopped)
TTE confirms the energy-in-EARLY-RISK-OFF toxicity pattern identified with COP. Both European energy (TTE) and US energy (COP) were stopped in the same EARLY RISK-OFF window on May 20. The sector rotation away from energy was driven by the same oil price crash. TTE's stop at -2.47% is slightly better than COP's -3.51% because European energy has lower beta to WTI, but both trades were structurally wrong. This is the third consecutive retro flagging energy exposure as problematic in risk-off regimes — the scanner-lessons.json blocking rule for energy + EARLY RISK-OFF must now be enforced as severity=blocking.
Lessons & Improvements
What the scanner got right ✅
- TSM (+6.35%) and MS (+5.33%) — quality mega-cap picks that survived regime oscillation
- ARM (+4.22%) identified correctly for the 2nd consecutive retro — AI breakout thesis proven
- Trailing stops protected capital: 40% breakeven rate means zero catastrophic losses
- Profit factor 1.98 — every $1 risked returned $1.98 on average
- Zero losses from RISK-ON 38 or RISK-ON 85 windows — regime adaptation worked post-EARLY RISK-OFF
- Sector rotation into defensives (NSRGY +2.03%) during EARLY RISK-OFF was correct
What the scanner missed ❌
- Energy exposure in EARLY RISK-OFF: COP (-3.51%) + TTE (-2.47%) = -5.98% avoidable losses
- COST breakout in EARLY RISK-OFF: breakout strategy hostile to risk-off regimes
- 40% breakeven rate is abnormally high — trailing stops working but entries may be too late
- RISK-ON 85 (3 scans) produced almost no winners — late entries after gap-ups
- Pullback strategy 0% WR — defensive pullbacks only generated breakevens (JPM)
- BTBT appeared twice (May 26 + May 27) — anti-doublon should have blocked 2nd entry
Lesson 1 — Energy exposure in EARLY RISK-OFF is toxic
COP (-3.51%) and TTE (-2.47%) were both energy momentum plays entered on May 20 during EARLY RISK-OFF 40. Oil crashed -4.78% on May 27. This is the 3rd consecutive retro flagging this pattern. Action: promote to severity=blocking in scanner-lessons.json. No energy momentum or breakout signals when GetRegimeProbability shows early_risk_off > 0.30.
Lesson 2 — Breakevens at 40% signal entry timing issues
Six of 15 resolved signals hit breakeven — trailing stops are correctly protecting capital, but the high BE rate suggests entries are coming too late relative to the move. The VWAP gate may be skipping gap-up entries on high-conviction days (RISK-ON 85). Action: investigate VWAP gate calibration for RISK-ON > 70 sessions. Consider a "gap-up pullback" entry variant that waits for intraday retracement before entry.
Lesson 3 — Quality mega-caps survive regime oscillation
TSM (+6.35%), MS (+5.33%), ARM (+4.22%) — the period's top 3 are all mega-caps with secular fundamental drivers (AI semis, bank M&A, IP royalties). Commodity plays (COP, TTE) and small-caps (BTBT) underperformed. Action: when regime oscillation is detected (2+ regime changes in 5 sessions), increase minimum market cap threshold to $50B and reduce commodity/small-cap allocation to max 1 per scan.
Lesson 4 — Pullback strategy needs regime confidence gating
Pullback yielded 0 wins — only breakevens from defensive names (JPM). In oscillating regimes, pullback entries face mean-reversion risk. Action: gate pullback strategy behind regime confidence > 60%. When regime confidence is low (oscillating), prefer momentum or breakout instead.
Lesson 5 — Regime confidence should inform sizing more aggressively
The regime penalty advisory (size x0.7 on oscillation) was correct but insufficient. RISK-ON 85 generated mostly breakevens despite max confidence — the problem was entry timing, not sizing. Action: separate sizing penalty (already implemented) from entry timing penalty (new). In RISK-ON > 70, require intraday -0.3% pullback from open before entry. In EARLY RISK-OFF, reduce from x0.7 to x0.5 for energy and cyclicals.

The 5 adjustments above + existing rules are encoded in scanner-lessons.json — machine-readable file consumed by /scanner Phase 0.8 at startup. Key updates this retro:
- Promoted to blocking: Energy + EARLY RISK-OFF = disqualify (was advisory, now blocking after 3 consecutive retros)
- New advisory: RISK-ON > 70 + gap-up = require intraday pullback before entry
- New advisory: Pullback strategy gated behind regime confidence > 60%
- Updated: Mega-cap preference during regime oscillation (min $50B when 2+ regime changes in 5 sessions)
- Open questions: VWAP gate calibration for gap-up sessions, breakeven rate persistence check at next retro
Methodology note — Rolling system
The B* grade reflects the 15 resolved trades of the period. The 9 pending trades (GOOGL, AAPL, CAT, NVDA, AMZN x2, ASML, ULCC) will be reclassified in the next retro as they resolve. By construction, the rolling 10-day system always has inflight positions at the tail end — a "definitive grade without inflight" does not exist. The Fortress portfolio return (+1.22%) captures real performance agnostic of individual trade resolution timing.
