I don't understand this advice at all: how is holding large stakes in a small number of businesses less risky than holding small stakes in a large number of businesses (i.e. stocks & shares)? When the economy tanks, surely there's a serious risk that revenue and profits in your businesses will fall. Moreover, if you're living off profits (dividends) the stock price is irrelevant anyway? Spreading your stakes in companies should <i>reduce</i> the risk, not increase it.<p>OK, if you built these businesses yourself, you might stand a better chance of accurately estimating the risk, but at the same time you'll have to stay involved with day-to-day operations, which has a cost too.
