It was a sobering start to the trading week for the S&P/ASX 200 Index (ASX: XJO) this Monday.
After scoring some new record highs last week, investors brought the ASX 200 back down to earth today. The index slipped a not-so-nice 0.69% to finish at 8,152.9 points.
This unhappy beginning for the Australian market's week comes after a mixed finish for the American trading week last Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) managed to eke out a gain, lifting 0.091%.
But the Nasdaq Composite Index (NASDAQ: .IXIC) wasn't so lucky, and slumped 0.36% lower.
Let's now return to the ASX and check out what the different ASX sectors were doing today.
Winners and losers
As one might expect, the losers outnumbered the winners this Monday.
Leading the losers were consumer staples shares. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) was a horror show, crashing 2.8%.
Real estate investment trusts (REITs) also had a rough time, with the S&P/ASX 200 A-REIT Index (ASX: XPJ) plunging 1.54%.
Consumer discretionary stocks were also on the nose. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) cratered 1.32%.
As were communications shares, evident from the S&P/ASX 200 Communication Services Index (ASX: XTJ)'s 1.1% tank.
Mining stocks did a little better. The S&P/ASX 200 Materials Index (ASX: XMJ) still had 0.67% taken off its top though.
ASX healthcare shares were right behind, with the S&P/ASX 200 Healthcare Index (ASX: XHJ) losing 0.65%.
Financial stocks had a cold bath as well. The S&P/ASX 200 Financials Index (ASX: XFJ) dipped 0.5%.
Our final losers were industrial shares, as you can see from the S&P/ASX 200 Industrials Index (ASX: XNJ)'s 0.32% slide.
Turning to the winners now, these were led by energy stocks. The S&P/ASX 200 Energy Index (ASX: XEJ) shot 0.94% higher today.
Utilities shares also had a corker, with the S&P/ASX 200 Utilities Index (ASX: XUJ) soaring 0.81%.
Gold stocks followed suit. The All Ordinaries Gold Index (ASX: XGD) added 0.43% to its value.
Finally, tech shares were spared from the sell-off, illustrated by the S&P/ASX 200 Information Technology Index (ASX: XIJ)'s 0.26% rise.
