Data through May 6, 2026 · All prices indexed to January 1, 2026 = 100
Thomson Reuters
NASDAQ: TRI
RELX (LexisNexis)
NYSE: RELX
Wolters Kluwer
OTC: WTKWY
NASDAQ: LZ
LegalZoom
−34.4%
$10.22 → $6.71 · Feb 3 drop: −20%
The only stock that continued declining after the initial crash.
As a pure-play, self-service legal platform, LZ faces the most direct substitution risk —
the Cowork plugin automates exactly the commoditized document workflows that drive its revenue.
NASDAQ: TRI
Thomson Reuters
−16.0%
~$114 → $95.76 · Feb 3 drop: −16%
Dropped sharply but has found a floor. Owner of Westlaw — arguably the most defensible
legal dataset in existence. Beat Q1 2026 earnings on May 5 with 9.8% revenue growth,
signalling its AI-native CoCounsel strategy is gaining real commercial traction.
NYSE: RELX
RELX (LexisNexis)
+3.0%
~$34.79 → $35.84 · Feb 3 drop: −14%
The standout recovery story — the only stock now above its January baseline.
RELX's diversification across Risk, Scientific/Medical, and Exhibitions means legal is
only one revenue pillar. The market ultimately agreed the selloff was irrational for a
business this structurally diversified.
OTC: WTKWY
Wolters Kluwer
−12.3%
~$88.80 → $77.86 · Feb 3 drop: −13%
Absorbed the shock but has not recovered. Reiterated full-year 2026 guidance on
May 6 with 5% organic revenue growth and 11% operating profit expansion —
operationally resilient, but the market continues to reprice its long-term
multiple in a world with native AI legal tooling.
