Question juridique clé
Whether administrative assistance under Art. 38 LBVM could be granted despite the appellant's objection of disproportionality and fishing expedition.
Solution extraite
The request was sufficiently linked to possible market manipulation; the Federal Court found enough indications to justify transmission.
Motifs extraits
The requested data concerned a concentrated, unusual trading pattern: the appellant sold 800,797 shares, representing 89.9% of the April volume, in a short period with price movements and atypical order execution. The requesting authority need only show sufficient indications of possible market distortion; the Swiss authority need not resolve the foreign merits or investigate every aspect.
