What moved
and why.

Proposed lessons

• proposed — A large unsigned implied move is useful as a volatility hurdle, not a directional signal. Here it correctly warned of substantial event risk but still understated the realized move. The disciplined pre-event conclusion was no directional edge, not that an outsized move was unlikely. For future autopsies, preserve the full release, guidance comparison, call transcript, and contemporaneous positioning evidence before assigning causality.
• proposed — A large implied move is a hurdle, not a ceiling. For distressed or highly uncertain issuers, apparently positive headline results can coexist with a much larger negative repricing when forward expectations or result quality change. Future blind analysis should preserve the disciplined directional abstention while explicitly treating absent guidance consensus and earnings-quality evidence as the main unresolved variables—not assume that expensive volatility makes an outsized move unlikely.
• proposed — When a high-multiple growth story enters earnings with accelerating-AI and 30%+ growth already prominent, headline beats and even a reported guidance raise may not clear the hurdle. Future blind work should explicitly model growth quality, deceleration, and customer concentration as separate surprise channels, while retaining a no-trade conclusion when the packet lacks the metrics needed to assess them.
• proposed — A disciplined abstention was appropriate: the sole pre-event signal—a ±17.56% implied move—described magnitude, not direction. The event produced a large upside reaction but did not clear the priced hurdle. The useful lesson is to preserve the distinction between predicting direction and evaluating volatility pricing; this case validates the high-volatility setup without demonstrating a blind directional edge.
• proposed — A highly anticipated beat is not itself a bullish catalyst when options already price an extreme move. Preserve the no-trade conclusion unless the pre-event packet exposes the specific expectations embedded in profitability, guidance, bookings, and earnings quality; headline beat sentiment alone cannot resolve direction.
• proposed — The useful pre-event signal was not that WDC would miss consensus, but that a stock framed as an AI-rally continuation test could fall even on headline beats if the embedded hurdle exceeded published estimates. Preserve that as a conditional setup, not a deterministic rule: require full guidance, margin and call evidence before assigning cause, and distinguish predicting direction from buying volatility because this decline remained inside the supplied implied move.
• proposed — The evidence-bounded no-outmove stance was the useful decision: generic growth, expansion, and pipeline headlines did not justify predicting a move beyond a roughly 12.2% hurdle. For future cases, require a quantified expectation gap or identifiable nonlinear catalyst before making an outmove call, and do not infer the cause of a post-earnings decline from a headline-level EPS beat—especially when revenue benchmarks conflict and guidance or call evidence is unavailable.
• proposed — A headline valuation case and an EPS-beat thesis are not sufficient earnings signals. Require explicit forward expectations and evidence on guidance, margins, segment demand, and positioning; treat a large implied move primarily as a hurdle, not a directional clue.
• proposed — A high implied move can be more useful for deciding whether to participate than sparse qualitative headlines are for choosing direction. Here, passing was defensible even though the stock rose: the directional clues were weak, and the realized 6.28% move did not clear the approximately 15.59% options hurdle.
• proposed — A positive EPS surprise and upbeat headline-level guidance are insufficient to predict the stock reaction when the expectations bar and key operating-metric consensus are unknown. The defensible pre-event decision was still to pass: the event moved down, but by less than the options-implied hurdle, and the packet does not reveal a repeatable clue that forecast that outcome.
• proposed — Separate direction from hurdle-clearing: the constructive result produced a positive stock reaction, but high pre-event expectations and volatility pricing meant that a sizable EPS beat still generated only about one quarter of the implied move. Pre-event optimism was useful for identifying hurdle risk, not for confidently predicting direction.
• proposed — Preserve timestamp alignment before judging an earnings thesis. Here, bullish clues correctly identified an elevated-expectations setup, but headline-level fundamentals could not determine direction or magnitude. More importantly, a same-day close cannot score an after-hours event. The defensible lesson is that beats alone are insufficient to clear a large implied-volatility hurdle—and that this particular case requires the first valid post-release price before that proposition can be tested cleanly.
• proposed — The defensible lesson is about calibration, not direction: the blind process appropriately abstained from a directional call, while the 12.13% priced move substantially exceeded the 3.87% realized move. This single event is consistent with a volatility-underperformance thesis, but it does not establish a repeatable volatility-selling edge or explain why the stock rose.
• proposed — The durable lesson is procedural: when pre-event evidence is low-resolution and contradictory, and options price an unusually large hurdle, neutral/avoid is a valid forecast outcome. A small headline beat does not establish a bullish reaction, but this case should not be used to teach that margin pressure caused the decline until the event timing, primary release, guidance, call record, and reaction window are verified.
• proposed — The blind process was appropriately calibrated: sparse cross-company and ownership clues did not justify a directional call, while the options hurdle supplied the useful forecast. Even a reported double beat with raised guidance produced only a +3.95% close-to-close move versus ±9.64% implied. Future analysis should preserve the distinction between predicting direction and predicting hurdle clearance, and should not treat outcome-aligned sector clues as validated without evidence of economic comparability.
• proposed — Candidate only: treat implied move as an approximate unsigned hurdle and regime descriptor, never as a directional signal or hard ceiling.
• proposed — Candidate only: score direction, absolute magnitude, hurdle clearing, and option-trade profitability as separate targets rather than collapsing them into one notion of correctness.
• proposed — Candidate only: require a quantified expectations gap before making a directional earnings call—reported results and guidance should be compared with consensus, prior guidance, revisions, whispers, and valuation-implied assumptions.
• proposed — Candidate only: model surprise channels separately, including forward guidance, growth quality, margins, customer concentration, bookings or backlog, cash flow, inventory, and management commentary.
• proposed — Candidate only: interpret visible optimism as a conditional hurdle-risk feature, not an automatic bearish signal. Test prospectively whether it adds information after controlling for valuation, revisions, momentum, and positioning.
• proposed — Candidate only: preserve explicit abstention when evidence cannot support direction, but define falsifiable abstention criteria in advance so retrospective scoring does not reward generic uncertainty language.
• proposed — Candidate only: require release-time alignment and compare reactions over predefined windows; use an event-matched option horizon or decompose non-event variance before evaluating implied versus realized movement.
• proposed — Candidate only: base causal autopsies on primary releases, numerical guidance, transcripts, contemporaneous analyst commentary, intraday paths, and market-adjusted returns before assigning mechanisms.
• proposed — Candidate only: evaluate these hypotheses on a prospectively assembled, non-outcome-selected sample with contamination controls and frozen prompts. Do not accept any lesson or alter weights from these cases alone.
