The S&P/ASX 200 Index (ASX: XJO) started the trading week on Monday with a shaky but overall positive performance.
After starting with a big sell-off, the ASX 200 spent most of the day recovering and ended up finishing with a 0.18% bump. That leaves the index at 8,300.2 points.
This rather wild start to our trading week comes after a rough end to the American week on Saturday morning (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) was out of form, sliding down 0.7%.
Things were even bleaker over on the Nasdaq Composite Index (NASDAQ: .IXIC), which tanked 2.24%.
But let's get back to this week and the ASX now with a checkup on what the various ASX sectors were doing today.
Winners and losers
Despite the gains of the overall markets, a few sectors were walked back this Monday.
The first and worst of those sectors were healthcare shares. The S&P/ASX 200 Healthcare Index (ASX: XHJ) was singled out for punishment and cratered 0.88%.
Tech stocks weren't in demand either, with the S&P/ASX 200 Information Technology Index (ASX: XIJ) slumping 0.79%.
Financial shares had a rough start to the week too. The S&P/ASX 200 Financials Index (ASX: XFJ) dropped 0.27%.
Real estate investment trusts (REITs) weren't much better, as you'll see from the S&P/ASX 200 A-REIT Index (ASX: XPJ)'s 0.2% fall.
Our final losers were communications stocks. The S&P/ASX 200 Communication Services Index (ASX: XTJ) slipped 0.05% today.
That's it for the red sectors. Turning to the green ones, it was ASX consumer staples shares that won the race this Monday. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) rocketed 1.95% higher.
Utilities stocks stood out too, with the S&P/ASX 200 Utilities Index (ASX: XUJ) soaring up 1.82%.
Gold shares were also on fire. The All Ordinaries Gold Index (ASX: XGD) surged 1.5%.
It was a great day to own energy stocks, illustrated by the S&P/ASX 200 Energy Index (ASX: XEJ)'s 1.47% vault up.
Broader mining shares also put on a show. The S&P/ASX 200 Materials Index (ASX: XMJ) galloped 1.15% higher.
Consumer discretionary stocks were a little more subdued, with the S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) lifting 0.25%.
Finally, industrial stocks did well. The S&P/ASX 200 Industrials Index (ASX: XNJ) bounced up 0.13%.
