Mirabaud Securities’ Neil Campling gained notoriety in 2020 when it emerged he was the only analyst who had placed a zero rating on Wirecard — more than a year before the scandal-ridden German payments firm collapsed.

Campling, who heads technology research at Mirabaud Securities, has been an outspoken critic of ARK Invest’s flagship Innovation ETF, overseen by star US fund manager Cathie Wood.
