By going global, investors are missing out on a rich vein of UK performance Let's consider a few. For Apple, say Arm. For LVMH, say Burberry. For Coca-Cola, say Diageo. For Boeing, say Rolls-Royce. For Porsche, say GKN. For JP Morgan, say HSBC. For Inditex, say Next. I can't get a UK equivalent of Google, but I think the point is made. There are many more pairs. A well informed, stock-picking UK fund manager can very easily identify global trends and pick a UK stock that will capitalise on the themes so loved by global equity fund managers and their investors. Last week, together with the popular UK strategy team at Oriel Securities, I decided to select 20 global mega-companies quite at random, pair them up with UK comparators and see how the two indices performed (see tables at end of article). The results shocked me, not because the UK selection beat the global selection of mega-caps but by how much it did so. The great UK company Arm has "out-teched" Apple, Burberry has out-blinged LVMH, GKN has overtaken Porsche and Rolls-Royce has flown higher than Boeing. There are more. A glance at how well the FTSE 250 (the second tier of UK companies by market capitalisation) has performed also makes the point that by going global, investors are missing out on a rich vein of performance. Since 1998 the FTSE 250 has risen by 190pc versus a FTSE 100 advance of only 35pc. So how has a random selection of global mega-stocks, so adored by so many at the expense of the few, done? Contrary to popular belief, on a straightforward share price basis - ie without accounting for currency movements - a global approach has not in fact beaten a local approach to "globalising" portfolios. A basket of UK global stocks playing the same themes followed by many has risen over the past five years by an average of 21pc per year versus a paltry 7pc per year from their more popular global equivalents, all of which are household names. Made in Britain can still be the best. And in a land of giants, Jack is king. Data supplied by Artemis Tim Steer manages the Artemis UK Growth Fund.
