Well, that didn't last long. After yesterday's tentatively positive start to the trading week, many investors may have hoped we had turned a corner on last week's disastrous performance of the S&P/ASX 200 Index (ASX: JO). Alas, it was not to be.
The ASX 200 started in red territory this morning and only got worse over the session. By the time trading ended, the index had lost 0.88% of its value and had settled at 8,672.5 points.
This rather terrible Tuesday for Australian investors came after a similarly downbeat night on Wall Street overnight to kick off the American trading week.
The Dow Jones Industrial Average Index (DJX: .DJI) did start strong, but ended up recording a 0.29% loss.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) fared even worse, dropping 0.56%.
But let's get back to the local markets now and take stock of how the various ASX sectors handled today's difficult trading conditions.

Winners and losers
Despite today's pessimism, we still saw a few sectors make hay.
But first, it was gold shares that copped the worst of it. The All Ordinaries Gold Index (ASX: XGD) ended up crashing 3.08%.
Broader mining stocks had a rough one as well, with the S&P/ASX 200 Materials Index (ASX: XMJ) cratering 2.21%.
Continuing with the commodities theme, energy shares also had a shocker. The S&P/ASX 200 Energy Index (ASX: XEJ) tanked 1.62% this session.
Financial stocks had a day to forget as well, illustrated by the S&P/ASX 200 Financials Index (ASX: XFJ)'s 1.08% plunge.
Real estate investment trusts (REITs) fared a little better. The S&P/ASX 200 A-REIT Index (ASX: XPJ) still lost 0.59%, though.
Industrial shares were right behind that, with the S&P/ASX 200 Industrials Index (ASX: XNJ) sliding 0.43%.
Our last losers this Tuesday were utilities stocks. The S&P/ASX 200 Utilities Index (ASX: XUJ) ended up slipping down 0.12%.
Let's turn to the green sectors now. Leading the winners were healthcare shares, as you can see from the S&P/ASX 200 Healthcare Index (ASX: XHJ)'s 1.5% surge.
Consumer staples stocks held their value, too. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) jumped 0.88% this session.
Its consumer discretionary counterpart was just behind that, with the S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) leaping 0.87%.
Communications stocks were spared as well. The S&P/ASX 200 Communication Services Index (ASX: XTJ) advanced 0.32%.
Finally, tech shares managed to stay on the right side of the line, evident by the S&P/ASX 200 Information Technology Index (ASX: XIJ)'s 0.29% bump.
