John Kay is a person with very clear views. His recommendations definitely carry weight.
Let’s get into the books you’ve chosen. As it’s the one you’ve traditionally recommended, let’s start with Burton Malkiel’s A Random Walk Down Wall Street (1973).
Yes, that’s the book I recommend when asked by people who are highly intelligent, have a little bit of money, but feel at sea. I’m not very impressed by financial advisers—for pretty good reasons. But there is very little you can read on investment that’s not insulting to the intelligence. As you know, there are lots of ‘how to become rich by day trading’ books around, but intelligent people know what to do with those kinds of books: namely not to open them.
