Warren Buffett has allowed leeway in his usual investment strategy by purchasing a 4% stake in POSCO back in 2006. He is well known to hate commodity companies as they do not have monopoly power and they only can compete on prices. The lowest cost commodity company will be the most profitable but only for a short while as the competitors will embarked on huge capital expenditures to lower their operating costs as well.
It is this idea that Warren Buffett loathes investing in any commodity companies. However, it seems that he has made an exception for POSCO STEEL and we shall see why.
