After two consecutive weeks of more than 200 basis points of growth in S&P 500 market prices, resulting from general enthusiasm over the stimulus decisions of the ECB, Fed, and Japanese Central Bank, the market took profits relatively quietly last week. Last week’s economic reports were generally flat.

Portfolio managers returning from their summer holidays have apparently liked what they’ve heard from the central banks. Although total volume remains modest, U.S. stock indexes have hit new highs. The S&P 500 finally busted out of its 3-month-long bullish rising channel.

Despite last Friday’s disappointing jobs report, stocks are staying strong. The S&P 500 hit yet another new high on Wednesday—its highest level since January 2008, while the Nasdaq is at a level not seen since toppling from its “irrational exuberance” days of late-2000 as the Internet bubble was bursting. The ECB seems to be getting a workable plan together to support the eurozone banking system and sovereign debt.

Volume remains low as the bulls continue to await Wall Street’s return from late summer vacations...and a firm plan from the central banks. (I think many portfolio managers must be spending their days in the stands at the U.S. Open tennis tournament.) The S&P 500 closed out August with a third straight monthly gain.
