Cementos Argos has seen a 110.3% stock increase since monetizing its US assets, outperforming the S&P 500's 31.1% rise. Despite recent financial weaknesses, including a 4.8% drop in cement volumes, I am upgrading CMTOY from 'Hold' to 'Buy'. The company benefits from expected housing sales growth, lower inflation, and a potential $2.87 billion cash influx from Summit Materials' sale.
