Invesco has taken the decision to dump unlisted holdings in two flagship investment funds — aiming to avoid a similar blowup to the one that hit the asset manager's former star Neil Woodford.

Triggering an immediate 5% loss for investors, the Henley-based asset manager announced on 31 March that it had applied a 60% writedown to unquoted stocks in Mark Barnett's £4.6bn High Income and £2.1bn Income funds.
