The S&P/ASX 200 Index (ASX: XJO) is back in the red on Thursday after briefly moving into positive territory earlier in the session.
At the time of writing, the benchmark is down 0.55% to 8,916 points after touching an intraday high of 8,983.8 points.
That leaves the market giving back Wednesday's 0.54% gain, although the index is still around 3% higher over the past week.
So, why has the local market lost ground today?

Wall Street gives investors a rough lead
Australian shares opened lower after a weak session in the United States overnight.
The Dow Jones Industrial Average Index (DJX: .DJI) fell 0.98%, while the S&P 500 Index (SP: .INX) dropped 1.2% following the latest US Federal Reserve meeting.
The central bank left its benchmark interest rate unchanged at between 3.5% and 3.75%. However, updated forecasts showed 9 of the 19 officials now expect at least one rate rise before the end of 2026.
Keep in mind that's a major change compared to March, when no officials were forecasting an increase this year.
Nonetheless, US share market futures rebounded strongly during the Australian morning, helping the ASX 200 briefly move into positive territory.
But that support didn't last long, with sellers returning before midday.
Miners and banks weigh on the index
The losses are spread across much of the market, with 123 stocks trading lower, 68 higher and nine unchanged.

There are still a few decent gains elsewhere in the market.
