Aussie stocks are having a rough day in mid-market territory after that initial green open. The ASX 200 dropped below 8,900, sitting at 8,864.40 and down 0.71% - looks like Wall Street's mixed signals overnight took the wind out of our sails. The broader All Ordinaries is also sliding, down 0.86%.

What's interesting is how the mid-market moves are playing out across sectors. Gold miners are getting hammered pretty hard - Evolution Mining down nearly 5%, Genesis Minerals tumbling 7%, and some of the bigger names like Newmont sliding over 5%. Meanwhile, the big four banks are holding up okay, edging up a bit. Energy stocks are mostly green with Santos pushing up almost 2%, though Origin Energy is struggling.

Tech is messy in the mid-market space too. Block and Zip are both taking hits, down 3-4%, but Appen just went crazy with a 27% jump after solid Q4 numbers. Lithium play Ioneer got smashed though - down 19% after announcing a capital raise.

On the economic side, producer prices beat expectations at 0.8% quarterly, and credit growth is running hotter than expected. The Aussie dollar is trading around 0.699. Mid-market traders are probably watching these data points closely to see if there's a shift coming. Pretty volatile session overall.
