Mark Slater is one of the most successful and widely followed growth fund managers in the UK. Since setting up Slater Investments 22 years ago, he and his team have delivered an exceptionally strong performance record across their growth and income funds.


A great deal of that success is down to an unshakable focus on buying good quality growth shares at reasonable prices. But equally, it’s about really understanding the nature and likely longevity of that growth. That means recognising the traits of different growth stocks and dealing with the psychological battles of buying, holding and selling these types of companies.

Since the crisis our approach has been to assume that life would be tough, and I think for the average business life is very tough. Having said that, zero rates have helped and certainly it could have been an awful lot worse. But the key thing is that coming out of the crisis valuations were so low that it didn’t surprise me that a lot of companies went up multiples.

On current market conditions...

Conditions have been a little more unsettled in 2016 so far. What’s your…
