Fund profile
As filed in the prospectus · 2025 Q4
The State Street SPDR Portfolio S&P 400 Mid Cap ETF (the Fund) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of mid-capitalization exchange traded U.S. equity securities.
The fund tracks the S&P MidCap 400 Index, which comprises U.S. mid-capitalization stocks with market capitalizations between $8 billion and $22.7 billion, selected for liquidity and profitability and weighted by float-adjusted market capitalization. The fund employs a sampling strategy, purchasing a subset of index securities chosen to replicate the index's risk and return characteristics rather than holding all constituents. Because the fund samples rather than fully replicates the index, its returns may diverge from the index.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
