The S&P/ASX 200 Index (ASX: XJO) and many ASX shares enjoyed a pleasant start to the trading week this Monday. After the positive momentum that we saw over most of last week, the ASX 200 kept it up today.
Despite a negative start this morning, the index broke into positive territory in afternoon trading and ended up closing 0.47% higher. That leaves the index back over 9,000 points at 9,019.3.
This happy start to the Australian trading week came after a similarly upbeat end to the American trading week on Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) overcame some early jitters to record a 0.53% rise.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) was even more upbeat, gaining a solid 1%.
But let's return to this week and our local share market now, and dig deeper into what was happening across the different ASX sectors today.

Winners and losers
Today's good mood was almost universal, with only two sectors missing out on a rise.
The first, and worst, of those red sectors was energy shares. The S&P/ASX 200 Energy Index (ASX: XEJ) had a tough one, slumping 1.19%.
The other unlucky corner of the markets was communications stocks, with the S&P/ASX 200 Communication Services Index (ASX: XTJ) slipping 0.01%.
Let's get to the green sectors now. Leading the winners were utilities shares. The S&P/ASX 200 Utilities Index (ASX: XUJ) was on fire, zooming up 2.1%.
Industrial stocks ran hot too, as you can see from the S&P/ASX 200 Industrials Index (ASX: XNJ)'s 1.36% surge.
Consumer discretionary shares didn't miss out either. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) soared up 1.1% today.
Its consumer staples counterpart was in the same ballpark, with the S&P/ASX 200 Consumer Staples Index (ASX: XSJ) spiking 1.03%.
Healthcare shares almost matched that gain. The S&P/ASX 200 Healthcare Index (ASX: XHJ) galloped up 102% this Monday.
Next came tech stocks, evidenced by the S&P/ASX 200 Information Technology Index (ASX: XIJ)'s 0.8% jump.
Gold shares snatched a win too. The All Ordinaries Gold Index (ASX: XGD) added 0.7% to its total this session.
Financial stocks were also popular, with the S&P/ASX 200 Financials Index (ASX: XFJ) leaping 0.41%.
We could say the same for mining shares. The S&P/ASX 200 Materials Index (ASX: XMJ) saw a 0.3% improvement.
Finally, real estate investment trusts (REITs) squeaked in over the line, illustrated by the S&P/ASX 200 A-REIT Index (ASX: XPJ)'s 0.04% uptick.
