Semtech to Join S&P MidCap 400, Exit SmallCap 600 on June 22
SMTC•SMTC•SMTC•SMTC•Semtech is being added to the S&P MidCap 400 index and removed from the S&P SmallCap 600 effective June 22, 2026 as part of the quarterly rebalance. The change aligns its market-cap classification with mid-cap peers and will prompt index-linked funds to adjust their Semtech holdings.
Semtech will be removed from the S&P SmallCap 600 and added to the S&P MidCap 400 prior to trading on June 22, 2026 as part of the quarterly index reconstitution. This adjustment reflects its market capitalization growth and ensures the indices accurately represent small-cap and mid-cap segments.
Inclusion in the MidCap 400 is expected to trigger inflows from funds and ETFs that track the mid-cap benchmark, while funds tied to the SmallCap 600 will divest shares. These shifts may boost trading volume and influence short-term share liquidity as passive portfolios rebalance.
