The Money Left on the Table

  • NVAX: Peak at $11.96 (10:55 AM) — exited at $11.17. Left $722 on the table.
  • OPEN: Peak at $5.44 — exited at $5.39. Captured most of the move.
  • RGTI: Peak at $19.20 (10:55 AM) — exited at $18.61. Left $317 on the table.
  • INTU: Peak at $406.25 (11:15 AM) — exited at $393.60. Left $260 unrealized.
  • STLA: Peak at $8.21 (9:35 AM, first 5 minutes) — faded all day.

Implications

  • The system works end-to-end. Scan, size, execute, close — all stages functioned. Profitable on day one despite execution delays.
  • Sell timing is the primary optimization target. Capturing only 24% of available alpha means the exit strategy is the biggest lever for improvement. This finding launched the sell-timing analysis and ultimately the V3 15:20 PM time exit.
  • Catalyst quality matters more than quantity. The two strongest performers (NVAX, OPEN) had clear reasons for their moves. STLA's bad-news gap was the largest loser.
  • Position sizing is validated. Equal dollar allocation worked as designed with no risk limit breaches.
