Explains — not advice

Confounded
33/100

Meta Platforms (FB) — a confounded move, NOT a contagion (score 33/100). The move coincides with a scheduled earnings report (Meta Platforms Q4 2021 earnings (after close)); attributable to that, not a contagion.

index case early peaklanguage / country jump

Each row is a community/country; every dot is a real post placed on the UTC timeline and shaded early → peak; cyan lines trace the narrative jumping across a language or border. The dashed shock line marks when price actually moved — dots to its left are the contagion forming before the market reacted, which is the lead this autopsy is built to expose.
