It was a volatile and ultimately negative start to the trading week for the S&P/ASX 200 Index (ASX: XJO) and ASX investors this Monday.
After starting the week's trading at an opening loss this morning, the ASX 200 spent most of the day bouncing around, but ended up closing down 0.026%. That leaves the index at 8,729.4 points.
This cold-shower start to the trading week for Australian investors follows a rosier finish to the American week on Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) was in decent form, rising a confident 0.72%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) wasn't quite as enthusiastic, but still managed a 0.2% gain.
But let's get back to this week and the local markets now, and check out how the various ASX sectors traversed today's tough trading conditions.

Winners and losers
There were more red sectors than green ones this Monday.
Leading the red sectors were healthcare shares. The S&P/ASX 200 Healthcare Index (ASX: XHJ) was hit hard, plunging 1.68% this session.
Real estate investment trusts (REITs) were also out of favour, with the S&P/ASX 200 A-REIT Index (ASX: XPJ) diving 0.7%.
Financial stocks had more sellers than buyers, too. The S&P/ASX 200 Financials Index (ASX: XFJ) dropped 33% today.
Consumer staples shares were no safe haven either, evidenced by the S&P/ASX 200 Consumer Staples Index (ASX: XSJ)'s 0.3% dip.
Utilities stocks came in just in front of that. The S&P/ASX 200 Utilities Index (ASX: XUJ) retreated 0.26% this Monday.
Industrial shares were also in that ballpark, with the S&P/ASX 200 Industrials Index (ASX: XNJ) getting a 0.23% trim.
We can say the same again for consumer discretionary stocks. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) slid 0.22% lower.
Our last losers this Monday were communications shares, illustrated by the S&P/ASX 200 Communication Services Index (ASX: XTJ)'s 0.19% slip.
Turning to the green sectors now, it was tech stocks that dominated. The S&P/ASX 200 Information Technology Index (ASX: XIJ) ended up rocketing 5.43% higher.
Gold shares were a little tamer, with the All Ordinaries Gold Index (ASX: XGD) jumping 0.68%.
Broader mining stocks weren't far off that. The S&P/ASX 200 Materials Index (ASX: XMJ) added 0.49% to its total this session.
Finally, energy shares managed to get over the line, as you can see from the S&P/ASX 200 Energy Index (ASX: XEJ)'s 0.34% improvement.
