I’ve found that it’s impossible to tell someone who either has made a big profit (on paper or otherwise), or who knows someone else whose made big profits that we’re not poised for another 10 years of increases. The smart money already knows that there are no short term increases in our immeditate future. The dumb money isn’t aware enough of exactly where they are to accurately gauge how little time they have left to get out in one piece.
If they ask my opinion I usually offer them the toned-down version that the market is already slowing up and in some areas declining a bit. There’s no upside in trying to foretell the depth of the decline, especially when there are so many variables in play. Unless I’m exactly right I’m an idiot, and there’s essentially no way to be exactly right.
