I know, not the sort of subject heading you all want to read, just before your Sunday roast. But, this is the headline in today's Sunday Times Money section. One or two brokers reckon that we are moving into a 'new investment age' characterised by lower returns. Goldman Sachs reckon that '..demographic patterns would have a serious effect on share prices which could triger the longest bear market in history'. Right, where's my mattress then , better stuff what's left in there.
