I don’t mean the ups-and-downs of the market … if you’re invested in the market, it behooves you to pay a bit of attention now and again. No, what I mean are the interpretations of what’s happening in the market and what is or isn’t driving it. Canadian Couch Potato has a good summary:
I remembered the joke this morning when I read the Financial Post’s daily market commentary: “The S&P 500 added more than 2% in the two previous sessions as immediate concerns over rising yields in Spain and Italy ebbed and on bets the Chinese GDP data would surprise on the upside.”
This commentary can sound so knowledgeable and wise. But to suggest that daily market movements can be explained in such simple cause-and-effect terms is laughable. If you want proof, all you need to do is read the commentary every day. You’ll just as often see statements like this: “The S&P 500 shed more than 2% in the two previous sessions despite immediate concerns over…”
It can’t work both ways: either these events affect daily stock prices, or they don’t. Once you accept this, you realize that commentary linking the S&P 500 to surprising Chinese GDP data sounds a lot like the joke about Katarina Witt and Billy Martin.
Here’s my own version of the daily market report: “The S&P 500 added more than 2% during the last two sessions because of an incredibly complex and largely random combination of factors that cannot possibly be distilled into one sentence. Analysts expect gains to continue during the second quarter, but since this already priced into the markets, no one should give a fiddler’s fart what they think. Meanwhile, money managers have released their forecasts for the year, which will be widely read and acted upon, despite the fact that their previous forecasts were dead wrong. Tune in tomorrow for more of the same. In the meantime, stick to your long-term plan.”
