ASX 200 closes little changed, with Bapcor leading gainers and Boss Energy the day’s worst performer; check top gainers and losers

Australian shares closed Thursday’s session (December 18) largely unchanged, with investors showing caution despite sharp moves in individual stocks. The S&P/ASX 200 inched up 3.00 points, or 0.03 per cent, to finish at 8,588.20, according to market data recorded at 4:42 pm AEDT.

The modest gain reflected a subdued trading day, with advances in some sectors offset by weakness in others. Over the past five trading sessions, the benchmark index has remained virtually flat, indicating a pause in momentum after recent highs. However, the broader trend remains positive, with the ASX 200 up 5.26 percent year-to-date.
