Chile's benchmark IPSA index closed 0.29% higher at 10,706 on Thursday, ending a two-day losing streak.
The modest gain reflects a shift in global market sentiment, driven by softer-than-expected US inflation data that has reduced pressure on risk assets across Latin America.
The recovery came despite headwinds from falling copper prices, which have weighed on mining-heavy portfolios in the region.
The index's ability to stabilize suggests that broader macroeconomic optimism is currently outweighing commodity-specific weakness for Santiago investors.
The move follows a volatile week for the Chilean market.
The IPSA had posted a third consecutive session of gains on Tuesday, closing 0.11% higher at 10,900.52, before reversing course on Wednesday with a 0.88% drop to 10,675.
