Retrospectives

tickermfemaereflection
TSLA S3+2.97%-0.82%

Signal: Direction was right — TSLA fell ~1.9% after entry — though note the rationale (Burry shorting Micron/Nvidia on semiconductor concerns) is only loosely connected to TSLA; the price data can't tell us whether the thesis or coincidence drove the move.

Timing: Fine — despite the -1.31% dip in the prior 30 minutes, entry at 313.95 was actually above the prior close, so the move had not already happened.

Exit: The dominant factor. The trade captured +1.92% of a +2.97% best unrealized (max drawdown only -0.82%), and the close was mechanical — netted out by an outranking long TSLA signal — not a judgment on the short itself, leaving roughly a third of the available move on the table. A correct signal with clean timing was truncated by an internal signal conflict, not by the market.

MU S1+7.73%-0.07%

Signal: Right — the bearish call played out, with the stock falling ~3.9% after entry. Timing: Good — entry came after a +1.36% rise (not chasing a drop), and the worst unrealized was only -0.07%, meaning the short essentially never went against you. Exit: The weak link — max favorable excursion was +7.73% but the trade closed at roughly +3.9%, capturing only about half of the available move. The dominant factor is exit execution: a correct, well-timed signal left nearly half the potential P&L on the table.

MU S4+20.27%-1.14%

Signal: right. The short thesis played out — MU fell from entry 890.77 to exit 820.55 (+$70.22, ~7.9%).

Timing: partially late. At decision time the price was ~933 (+1.36% vs prev close 920.95), but the fill came at 890.77 — roughly 4.5% of downside occurred between decision and fill, though ample move remained afterward.

Exit: the dominant factor, and it's the weak point. Best unrealized was +20.27% (~$180) against a realized ~7.9%, so the mechanical exit-at-next-close gave back over half of the available move; drawdown risk was trivial (-1.14%). The signal and residual timing were fine — the exit captured well under half of what the trade offered.

📖 Glossary

  • S1 primary — trades the alert's primary ticker in the direction the article itself indicates; exits at the same day's close.
  • S2 counterparty — trades the inferred counterparty ticker (weakest signal, LLM-inferred sympathy); exits at the same day's close.
  • S3 peer — trades an inferred peer ticker (also LLM-inferred sympathy); exits at the same day's close.
  • S4 overnight — holds the primary ticker from today's close to the NEXT day's close.
  • Verdicts are decided top-to-bottom, first match wins; REPRICING is also the fallback when nothing else matches (2026-08-08 #220).
  • UNKNOWN — a needed price input (move since close or move in the last 30m) is missing.
  • PRICED — |move since previous close| ≥ 2.0%: already reflected in price.
  • REPRICING — |move in the last 30m| ≥ 0.5%: the tape is actively moving on it. Also covers a quieter move — |move since previous close| in [1.0, 2.0) with a quiet last-30m tape: still developing, not yet priced.
  • FRESH — |move since previous close| < 1.0%: a genuinely new move.
  • materiality — how market-moving the story was judged, 0-100 — alerts require materiality ≥ 60.
