Previously called LF Blue Whale Growth
Managed by Blue Whale co-founder Stephen Yiu, who is supported by Daniel Allcock, this is a truly active fund with a very concentrated portfolio of just 25 to 35 stocks. The fund only invests in the highest quality businesses, although Stephen pays close attention to valuations. He also ignores structurally challenged industries or businesses. We like the team’s disregard for any sort of benchmark, their willingness to be pragmatic and the fund’s ability to adapt.
Stephen Yiu, Daniel Allcock
Stephen Yiu is the lead manager and the co-founder of the WS Blue Whale Growth fund. Stephen started his career at Hargreaves Lansdown, before leaving in 2007 to work with Tim Steer – first at New Star and then at Artemis, where he managed or co-managed several funds. Immediately before launching the Blue Whale fund, Stephen worked under Martin Taylor and Nick Barnes at Nevsky Capital.
WS Blue Whale Growth has a very clear philosophy and the manager knows exactly what sort of companies he wants to own. We like the team’s disregard for any sort of benchmark, and we applaud the determination to invest in its own research. We also like the manager’s willingness to be pragmatic and the fund’s ability to adapt. The fund may be young, but the execution of the process and its performance has been excellent so far. We like the team’s disregard for any sort of benchmark, their willingness to be pragmatic and the fund’s ability to adapt.
