Equity markets advanced on Tuesday, driven by hope for cooling inflation and news from the retail sector. Private equity firms have made a joint offer to take mall-based Macy's private. The deal alleges the stock is deeply undervalued, highlighting value across the industry. Names like Kohl's and Abercrombie & Fitch also advanced on the news gaining mid to high-single digits for the day.

Today's market-moving event will be the CPI index. The index is expected to reveal that core inflation is holding steady compared to the previous month, keeping the FOMC in wait-and-see mode. The risk for traders is hotter or cooler than expected data, with the FOMC meeting set for Wednesday. The committee isn't likely to alter its policy but could begin to signal the next policy shift, which would be a bullish catalyst for the market. The S&P 500 advanced 0.4% for the session setting a new high for the year; the index is still below significant resistance targets at the current all-time high.
