Krystal Biotech Joins S&P MidCap 400 as TMHC and AVNS Exit

Key Facts

1Krystal Biotech joined the S&P MidCap 400 index as part of an index rebalancing.
2TMHC and AVNS exited the indexes as part of these periodic adjustments.

In a move reflecting the evolving market capitalizations within the healthcare sector, S&P Dow Jones Indices has announced that Krystal Biotech will join the S&P MidCap 400. This inclusion is part of a scheduled index rebalancing process. Concurrently, Taylor Morrison Home Corp (TMHC) and Avanos Medical (AVNS) have exited the index as part of these periodic adjustments, according to analyst reports.

Index inclusion typically triggers significant inflows from passive funds and ETFs tracking the benchmark, providing a liquidity catalyst for Krystal Biotech. Compared to its biotechnology peers, this elevation enhances the company's visibility among institutional investors. Conversely, exiting companies like TMHC often face short-term selling pressure as institutional portfolios reallocate capital away from the delisted constituents.

Traders should monitor trading volumes for KRYS as the rebalancing takes effect. Looking ahead, the broader market will be focused on the U.S. Consumer Price Index (CPI) data scheduled for July 14, 2026. These inflation figures are critical catalysts that could dictate sentiment for mid-cap growth stocks and the broader healthcare sector in the coming weeks.
