I suggest that teddy take a basic course on investment analysis.
low rental yield for properties is not the same as low dividend for stocks. Some stocks are in growth industries, and need the cash flow for product and market expansion purposes. hence, the low dividend payout ratio. But when these companies mature and need less cash for expansion purposes, they will be able to pay loads of cash (dividends). that explains why these firms have a high P/E ratio now or, in your words, high capital gain potential.
low rental yield is an entirely different thing. It means that the properties have no fundamentals. renters don't see the point of paying high rents for these properties, as is the case for orcard properties. so in the case of properties, low rental yield is the same as low capital gain potential.
I see teddy as a very good example of how many singaporeans are so rich but so seemingly naive of basic economic principles. the only conclusion I can draw is that many singaporeans get their money through inheritances, not through hard work or smart investments.
