The S&P/ASX 200 Index (ASX: XJO) endured another lacklustre session this Tuesday. After starting the week on a negative note yesterday, investors didn't exactly come back to the markets with a renewed sense of optimism today.
The ASX 200 spent the entire session in red territory, and ended up closing with a 0.057% loss. That drags the index down to 8,724.4 points.
This rather uninspiring Tuesday session for the local markets comes after a more positive start to the American trading week up on the US markets last night.
The Dow Jones Industrial Average Index (DJX: .DJI) had a wild ride, but managed to pull off a win, gaining 0.091%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) was a little more decisive, rising 0.42%.
But let's return to the ASX boards now and take stock of what the different ASX sectors were up to amid today's challenging trading conditions.

Winners and losers
Despite the broader market's backward step, many sectors advanced in value.
But first, it was real estate investment trusts (REITs) that were targeted by sellers above all else. The S&P/ASX 200 A-REIT Index (ASX: XPJ) cratered by 1.52% this session.
Consumer staples stocks weren't in favour either, with the S&P/ASX 200 Consumer Staples Index (ASX: XSJ) diving 1.31%.
We could say the same for healthcare shares. The S&P/ASX 200 Healthcare Index (ASX: XHJ) had tanked 1.21% by the time the markets closed.
Financial stocks had another tough one too, as you can see from the S&P/ASX 200 Financials Index (ASX: XFJ)'s 1% plunge.
Consumer discretionary shares fared a little better. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) still lost 0.6% of its value, though.
Utilities stocks were our last losers, with the S&P/ASX 200 Utilities Index (ASX: XUJ) getting walked back by 0.41%.
Turning to the green sectors now, it was again tech shares that topped the pile. The S&P/ASX 200 Information Technology Index (ASX: XIJ) soared another 4.71% higher this Tuesday.
Gold stocks ran hot as well, evident by the All Ordinaries Gold Index (ASX: XGD)'s 2.83% surge.
Broader mining shares put in a solid day's work too. The S&P/ASX 200 Materials Index (ASX: XMJ) vaulted up 1.25%.
Communications stocks were also in demand, with the S&P/ASX 200 Communication Services Index (ASX: XTJ) jumping 1.07%.
Energy shares kept themselves in the good books. The S&P/ASX 200 Energy Index (ASX: XEJ) enjoyed a 0.36% lift today.
Finally, industrial stocks got over the line, illustrated by the S&P/ASX 200 Industrials Index (ASX: XNJ)'s 0.04% uptick.
