It is time once again for Halloween and it’s time once again for (participating) homeowners/renters to open their doors to hordes of kids dressed up in the scary best.

But it is not just homeowners who will are receiving a scare.

After starting the week in positive territory, the Australian bourse has turned around and dived into the red today, sending the benchmark ASX 200 tumbling 0.84% to 7,350.7 points for the week.

All sectors save health care plummeted today with real estate and communication services posting the biggest losses.

Investor attention is increasingly turning to the bond market, after the RBA refrained from buying three-year government bonds this week.

There’s been a sharp move higher in Australian bond yields across the curve in Friday trade, and stocks moved lower in response.
