[BRIEFING.COM] The stock market powered up at today's open, energized by positive responses to earnings reports from Dell (DELL 114.52, +3.78, +3.4%), Autodesk (ADSK 262.23, +4.00, +1.6%), lululemon athletica (LULU 256.21, -2.80, -1.1%), Marvell (MRVL 76.42, +6.58, +9.4%), and MongoDB (MDB 285.74, +40.02, +16.03), and some pleasing economic data, namely the Personal Income and Spending report for July.
Around mid-morning, however, there was a power outage so to speak that sucked the energy out of the major indices and rolled them into negative territory. There wasn't a news catalyst for the reversal, which looked to be a function of selling interest in front of the Labor Day holiday weekend and possibly some month-end activity.
At their highs of the morning, the Nasdaq, S&P 500, Russell 2000, and Dow Jones Industrial Average were up 1.1%, 0.7%, 0.6%, and 0.4%, respectively. Those gains faded away as the large-cap/mega-cap stocks faded away from higher levels and a general sense of attrition took root.
Advancers had been outpacing decliners by a 2-to-1 margin at the NYSE and by an 11-to-6 margin at the Nasdaq. That line has since flipped. Decliners now lead advancers by a nearly 2-to-1 margin at the NYSE and by a 3-to-2 margin at the Nasdaq.
Earlier, ten of the 11 S&P 500 sectors were trading higher with only the energy sector (-0.6%) in negative territory as it dealt with sliding oil prices ($73.75, -2.16, -2.9%) tied to a Reuters report that OPEC+ is likely to raise its output by 180,000 barrels per day in October. Now, there are five sectors trading lower with losses ranging from 0.02% (utilities) to 0.5% (energy), so nothing material in a thinly-traded market that would like to hurry up the closing bell to get on with the three-day weekend.
The consumer discretionary sector (+0.5%) is today's best-performing sector, led by Amazon (AMZN 175.13, +3.01, +1.8%) and Tesla (TSLA 209.51, +3.23, +1.6%).
