20 years of investing: what I’ve learnt, and my best and worst investments

James Thomson has been managing Rathbone Global Opportunities for over 20 years. In an interview with interactive investor’s collectives editor Kyle Caldwell, he explains that one of the biggest investment lessons he's learnt is that “expensive doesn’t always mean overvalued”. He uses Nvidia as a recent example. It has seen its price-to-earnings (P/E) ratio fall from 70x earnings to 30x earnings due to the market “underestimating the earnings potential of the growth of this business".

Thomson also names his best and worst investments over the 20-year period, credits his mother for one of his holdings, and explains that he's been looking more closely at the UK market, as it is an area that he'll be increasing exposure to in the coming months.
