News Detail

The S&P/ASX 200 Index (ASX: XJO) managed to kick off the trading week on a positive note, despite a rough start to trading this morning. Amid concerning geopolitical developments over the weekend, the ASX 200 opened deep in the red this morning, but managed to recover throughout the day to close 0.0025% higher.

This volatile start to the trading week for Australian investors follows a decidedly negative finish to the American trading week on Saturday morning (our time).

The Dow Jones Industrial Average Index (DJX: .DJI) finished its week on a low note, sinking 1.05%.

The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) was in a similar boat, dropping 0.92%.

But let's return to this week and the local markets now with a look at how the different ASX sectors handled today's temperamental trading conditions.

Winners and losers

There were plenty of both red and green sectors this Monday.

Leading the former were tech stocks. The S&P/ASX 200 Information Technology Index (ASX: XIJ) was singled out for punishment, cratering 3.06%.

Financial shares were also on the nose, with the S&P/ASX 200 Financials Index (ASX: XFJ) tumbling 1.77%.

So too were consumer discretionary stocks. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) was sent home 0.83% lower today.

Healthcare shares weren't popular either, as you can see from the S&P/ASX 200 Healthcare Index (ASX: XHJ)'s 0.6% dive.

Utilities stocks also had a day to forget. The S&P/ASX 200 Utilities Index (ASX: XUJ) gave up 0.4% of its value this session.

Real estate investment trusts (REITs) were right behind that, with the S&P/ASX 200 A-REIT Index (ASX: XPJ) sliding down 0.39%.

Communications shares were our last losers today. The S&P/ASX 200 Communication Services Index (ASX: XTJ) ended up slipping 0.12% lower.

Now with the red sectors out of the way, let's get to the green ones.

Leading the pack were energy stocks, as evidenced by the S&P/ASX 200 Energy Index (ASX: XEJ) rising 5.5%.

Gold shares ran hot as well. The All Ordinaries Gold Index (ASX: XGD) soared up 4.73% today.

Then we had consumer staples stocks, with the S&P/ASX 200 Consumer Staples Index (ASX: XSJ) galloping 2.35% higher.

Mining shares weren't left out of the party. The S&P/ASX 200 Materials Index (ASX: XMJ) enjoyed a 1.95% bounce this session.

Finally, industrial stocks managed to stick the landing, illustrated by the S&P/ASX 200 Industrials Index (ASX: XNJ)'s 0.05% improvement.
