Vanguard’s newly-launched UK online retail platform has contributed to a significant uptick in passive fund sales during the past six months, a report has claimed.

Research analysts at US fund manager AllianceBernstein have suggested Vanguard’s online fund platform, which launched to much fanfare in May, has helped passives grow their market share in the UK to 27.8%. This is up from a 23.8% share noted shortly before the low-cost asset manager unveiled its online service.
