The Financial Conduct Authority this week published short-position data under
its new regime, which replaces name-level disclosure of significant short
holders with aggregated per-stock totals, the Financial Times reports. Data
provider Breakout Point identified multiple clear errors: positions later
deleted or altered with no visible amendment record, and some entries that
appear to be years-old and unlikely to still exist. Breakout Point founder Ivan
Kosovic said initial errors may be forgivable as the system beds in but that
'invisible edits' to official market records should not become normal. The
release has prompted market questions about the reliability of the new
disclosure dataset.
