The S&P 500 (^GSPC -0.88%) gained 0.4%, with the Dow Jones Industrial Average (^DJI 0.56%) unchanged (up four-hundredths of a percentage point, to be absolutely precise.) The gap in performance between the two indexes largely reflects the difference in weightings assigned to IBM (IBM 0.06%), which represents nearly 12% of the Dow, against less than 2% of the S&P 500. Shares of the tech stalwart fell close to 5% today -- yesterday's after-hours earnings report was poorly received.

The short view: Premium card issuer American Express (AXP 6.22%), which reported its third-quarter results after the bell, came in exactly in line with analysts' expectations, earning $1.09 per share. The world's largest card issuer by purchase volume, American Express is an interesting bellwether for consumer spending habits -- particularly more affluent consumers. Card-member spending grew 8% in the third quarter, but while that is a better result than the one achieved in the second quarter, it falls short of the double-digit growth achieved over the prior nine quarters. That suggests that American Express' affluent clientele's outlook for the economy deteriorated somewhat last quarter, which isn't encouraging.

The long view: Delegates polled at the CFA Institute's Asset Allocation for Private Clients Conference today expect only 7% equity market returns over the next 10 years. In an article published in last Sunday's New York Times, Robert Shiller of Yale said that, based on the market's current valuation, investors should expect annualized gains of just under 4% after inflation (note that assuming inflation in a range of 2% to 3% annually gets us pretty near 7%). In the same article, Jeremy "Stocks for the Long Run" Siegel of the Wharton School says stocks could return 10% to 12% a year over the next several years.

Whom to believe? I'm giving the nod to Shiller and the "wisdom of crowds" here: To justify a 10% to 12% annual return, you need to believe stocks are now significantly undervalued, whereas I tend to think they are, at best, fairly priced. Nevertheless, there are opportunities to earn greater than 7% -- one of The Motley Fool's top analysts believes you can Secure Your Future With 9 Rock-Solid Dividend Stocks.
