It was a volatile, but ultimately positive, start to the trading week this Monday for the S&P/ASX 200 Index (ASX: XJO) and many ASX shares.
By the time the markets closed up this session, the ASX 200 had inched 0.056% higher. That leaves the index at 8,972.4 points.
This rather tentative start to the Australian trading week comes after a jubilant finish to the American week last Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) was on fire, exploding 1.89% higher.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) was just as euphoric, shooting up 1.88%.
But let's get back to this week and the local markets now and take stock of what the different ASX sectors were up to today.

Winners and losers
We had large helpings of both winners and losers this Monday.
Starting with the latter, financial stocks took the brunt of today's selling. The S&P/ASX 200 Financials Index (ASX: XFJ) gave up an early lead this morning to plunge 1.18% lower by the closing bell.
Consumer discretionary shares had a tough day as well, with the S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) tanking 0.91%.
Its consumer staples counterpart wasn't much better. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) took a 0.78% dive today.
Communications stocks got up on the wrong side of the bed as well, as you can see by the S&P/ASX 200 Communication Services Index (ASX: XTJ)'s 0.67% drop.
Industrial shares didn't see any love either. The S&P/ASX 200 Industrials Index (ASX: XNJ) was sent home 0.62% lighter this session.
We could say the same for utilities stocks, with the S&P/ASX 200 Utilities Index (ASX: XUJ) dipping 0.46%.
But that's it for the losers. Turning to the green sectors now, it was gold shares that ran hottest. The All Ordinaries Gold Index (ASX: XGD) saw its value balloon 2.79% this Monday.
Broader mining stocks were in high demand too, illustrated by the S&P/ASX 200 Materials Index (ASX: XMJ)'s 2.72% spike.
Continuing the commodities theme, energy shares came next. The S&P/ASX 200 Energy Index (ASX: XEJ) galloped a healthy 1.12% higher today.
Real estate investment trusts (REITs) were in fine form too, with the S&P/ASX 200 A-REIT Index (ASX: XPJ) enjoying a 0.85% surge.
Next up were healthcare stocks. The S&P/ASX 200 Healthcare Index (ASX: XHJ) joined the ASX party and rose 0.36% this session.
Finally, tech shares saw some interest, evident by the S&P/ASX 200 Information Technology Index (ASX: XIJ)'s 0.27% lift.
