The S&P/ASX 200 Index (ASX: XJO) had a rough start to the trading week this Monday, giving up an early rise to end the day down rather heftily. After an early surge, the ASX 200 took a big dive mid-morning from which it never recovered.
By the end of the session, the index had tanked 0.76% and fell below 7,000 points, finishing the day at 6987.6 points.
Today's miserable start to the week's trading comes after a bit of a mixed bag over on the US markets last Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) finished the American trading week on a positive note, gaining 0.33%. However, the Nasdaq Composite Index (NASDAQ: .IXIC) wasn't so fortunate, suffering a loss of 0.11%.
But let's get back to the local markets now, and see where today's disappointing outcome came from with a deeper look at the various ASX sectors.
Winners and losers
Today's standout loser was the real estate investment trusts (REIT) space. The S&P/ASX 200 A-REIT Index (ASX: XPJ) had a tough day, cratering by 1.35%.
Consumer discretionary shares were almost as shunned by investors, with the S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) losing a nasty 1.26%.
Then we had mining stocks. The S&P/ASX 200 Materials Index (ASX: XMJ) had a day to forget as well, shedding 1.13% of its value.
Next up was the consumer staples sector. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) had a miserable time of it and slid 0.97% lower.
Healthcare shares were next. The S&P/ASX 200 Healthcare Index (ASX: XHJ) wasn't left out of the pity party and took a 0.56% backward step.
Following healthcare shares were financial stocks. The S&P/ASX 200 Financials Index (ASX: XFJ) also had a poor showing and retreated by 0.51%.
