The usual suspects of Materials, Industrials, Financials and Energy continue to lead this unstable market both up and down. Technology has been less volatile, and in fact it has been tracking closely with Healthcare lately. These two also happen to rank the highest this week in Sabrient’s SectorCast ETF rankings.

Investors dumped equities late last week ahead of the weekend – largely due to the tenuous situation with Greece’s debt and the associated fall in the euro (and a commensurate rise in the dollar). But I also think there was a flight-to-safety ahead of the 9/11 anniversary, especially among Wall Street traders given the terror threats and heavy security in NYC.

Last week, the stock market gave us epic swings. Bears came out with predictions of global economic meltdown as the market tanked, and then bulls came out trumpeting once-in-a-generation valuations when the market bounced.

Though the Federal government avoided a debt default with an eleventh hour deal for raising the debt ceiling, investors are apparently unimpressed—especially given the uninspiring economic reports. This week, the Commerce Department reported that personal spending in June fell for the first time in two years. This was coupled with the weak ISM manufacturing report and last Friday’s weak GDP report.

Needless to say, the Federal debt ceiling issue is now dominating the news wires, and although investors have so far been confident that some deal would be reached, the late hour is starting to spook some. After being given a glimmer of hope last week, we learned after last Friday’s close that the debt debates had fallen apart, leaving investors squirming about what this critical week ahead of us would bring.
