The S&P/ASX 200 Index (ASX: XJO) has had a rough start to the week's trading this Monday.
The ASX 200 was in the red all day, and by the close of trading, the index had finished up at 7,309.2 points, a loss of 0.22%.
The miserly start to the week comes after a similarly negative night of trading up on Wall Street last Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) started off strong but ended up choking and closed out with a 0.42% loss. The Nasdaq Composite Index (NASDAQ: .IXIC) had an almost identical experience, dropping by 0.36%.
But let's now see what today had in store for local investors on the ASX with a look at the different ASX sectors.
Winners and losers
With the markets falling today, it won't be much of a shock to learn that most of the ASX sectors also finished up in the red.
The worst place to be this session was in ASX healthcare shares. The S&P/ASX 200 Health Care Index (ASX: XHJ) endured a nasty fall today and ended up closing with a loss of 1.08%.
ASX financials shares were another sore spot, but the S&P/ASX 200 Financials Index (ASX: XFJ) didn't fare as badly as the healthcare index, only losing 0.38%.
It was a similar story with ASX tech stocks, with the S&P/ASX 200 Information Technology Index (ASX: XIJ) slipping by 0.31%.
Miners were another sector with a similarly-sized slide. The S&P/ASX 200 Materials Index (ASX: XMJ) recorded a drop of 0.32%.
That was slightly worse than the consumer staples space. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) retreated by 0.26%.
Let's turn to the winners, and leading the pack were real estate investment trusts (REITs). The S&P/ASX 200 A-REIT Index (ASX: XPJ) banked a pleasing rise of 0.54% by the close of trading.
Utilities shares were another bright spot, demonstrated by the S&P/ASX 200 Utilities Index (ASX: XUJ)'s 0.4% increase.
Just in front of that, we have ASX consumer discretionary shares. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) had a decent performance, lifting by 0.46%.
Energy shares banged out a similar showing, with the S&P/ASX 200 Energy Index (ASX: XEJ) inching 0.26% higher.
