Earnings Analysis
Why this page exists: PLXS has no documented material pre-announcement habit — the edge here is the earnings-cycle statistics themselves (drift, gap, reaction, follow-through) and how they vary by regime. This page
measures every earnings cycle — drift into the report, the gap, the reaction,
the follow-through — alongside the NVDA / SPY / VIX regime it happened in, and
uses the documented pre-announcement history to project when the next
pre-announcement is most likely to land. All numbers are computed from real
daily prices, real earnings dates, our own ATM-straddle expected moves and
stored option chains, and a
curated registry of real press releases. Nothing is simulated.

Methodology: reaction day = first trading day after the report (AMC assumed). Regimes are 20-trading-day returns (NVDA/SPY/SOX) and VIX close on the report date. Historical implied volatility before our options-DB coverage window (Nov 2025) is NOT reconstructed — realized volatility (HV20) is shown instead. Options strategy P&L and IV crush are priced from OUR OWN stored option chains (one row per contract per pull) for every cycle inside coverage; both sections grow automatically each quarter. Buckets with n<10 are exploratory. Correlation is not causation; small samples dominate the pre-announcement analysis. Pre-announcement registry: screeners/earnings_analysis/preannouncements_PLXS.json.
