The S&P/ASX 200 Index (ASX: XJO) started the short week in the red, falling 0.11% in Monday's session to close at 7,322 points.
Weighing it down was the mining sector, with two of the S&P/ASX 20 Index (ASX: XTL)'s materials giants – Fortescue Metals Group Limited (ASX: FMG) and South32 Ltd (ASX: S32) – posting apparently disappointing quarterly production updates.
The S&P/ASX 200 Materials Index (ASX: XMJ) slumped 1.6% while shares in Fortescue dumped 3.4% and those of South32 tumbled 7.4%. The sector was likely hampered by iron ore futures, which fell 1.8% on Friday to US$117.21 a tonne.
The top-performing sector, on the other hand, was the S&P/ASX 200 Real Estate Index (ASX: XRE). It jumped 1.2%.
