State Street SPDR Portfolio S&P 600 Small Cap ETF (SPSM US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P SmallCap 600 Index offers committee-selected U.S. small caps, generally occupying the lower single-digit USD-billions market-cap segment, with explicit investability and profitability screens. At addition, unadjusted market cap must fall within S&P’s small-cap guidelines (e.g., around USD 1–6.7bn) and float-adjusted market cap must be ≥USD 500mn; public float must be ≥10%. Liquidity requires an annual dollar value traded to float-adjusted market cap ratio ≥0.75 and trading of at least 250,000 shares in each of the six months before evaluation. Constituents must have positive as-reported earnings in the most recent quarter and cumulatively over the prior four quarters; sector balance versus the relevant S&P Total Market Index size slice is considered. Weighting is free-float market-cap; rebalancing occurs quarterly in March, June, September, and December, with ongoing committee-driven maintenance for corporate events and additions/deletions.


State Street SPDR S&P 600 Small Cap Growth ETF (SLYG US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P SmallCap 600 Growth Index targets the growth subset of the S&P SmallCap 600 universe, whose membership is set by an Index Committee using liquidity and financial-viability screens and typical small-cap addition guidelines around USD 1.2–8.0 billion total market cap. Growth scores are computed from three factors—three-year sales growth, earnings-change-to-price, and momentum—applied to S&P 600 constituents; stocks can receive partial weights in both growth and value based on style probabilities. The index is float-adjusted market-cap weighted using the parent’s float shares, with quarterly share updates and the style classification reviewed annually. Rebalancing implements style-weight updates on the annual schedule for S&P U.S. Style Indices, with standard S&P index corporate-action treatment; turnover is moderated by assigning only the incremental portion of each company’s float to growth according to its style probability, leaving the remainder in value.


State Street SPDR S&P Semiconductor ETF (XSD US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Semiconductor Select Industry Index offers equal-weighted exposure to US semiconductor and semiconductor equipment companies drawn from the S&P Total Market Index. Constituents must meet combined size/liquidity tests using float-adjusted market cap (FMC) and a float-adjusted liquidity ratio (annual dollar value traded ÷ FMC): either FMC ≥ USD 500m with liquidity ≥90%, or FMC ≥ USD 400m with liquidity ≥150%. If the industry falls below the minimum constituent count (35), selection thresholds may be relaxed per the Select Industry framework to maintain breadth. All eligible names are equally weighted at each rebalance; deletions follow removals from the S&P Total Market Index and GICS reclassifications. The index rebalances quarterly after the close on the third Friday of March, June, September, and December, using reference prices from the second Friday of each quarter-ending month.


State Street SPDR Portfolio S&P Sector Neutral Dividend ETF (SPDG US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Sector-Neutral High Yield Dividend Aristocrats Index targets U.S. equities with sustainable and growing dividends while matching the GICS sector weights of the S&P Composite 1500. The universe is the S&P Composite 1500, with stocks required to have at least seven consecutive years of flat or rising regular cash dividends and to meet S&P’s standard free-float market-cap and liquidity screens used for that parent index. Eligible stocks are ranked by indicated dividend yield within each sector, and a fixed number of high-yield names is selected per sector to keep overall sector weights close to the parent. Constituents are float-adjusted market-cap weighted and then constrained so sector weights remain sector neutral and no single stock becomes overly concentrated. The index is reconstituted and rebalanced annually, with buffer rules to limit unnecessary turnover.


State Street SPDR S&P Retail ETF (XRT US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Retail Select Industry Index offers modified equal-weight exposure to the Retail segment of the S&P Total Market Index, spanning apparel, automotive, broadline, consumer-staples merchandise, computer & electronics, drug, food retailers, and specialty stores. Securities must be S&P TMI constituents and pass size/liquidity investability screens; IPOs require sufficient trading history. At each quarterly rebalance, constituents are initially equal-weighted, then constrained by a maximum basket liquidity weight derived from each stock’s 3-month median DTV relative to a Theoretical Portfolio Value; an iterative process redistributes any residual weight across remaining names. A final concentration check caps any one stock at ≤4.5% if needed. Membership and weights are refreshed quarterly, using reference data from the last business day of February/May/August/November, with changes implemented after the close on the third Friday of March/June/September/December.


State Street SPDR S&P Regional Banking ETF (KRE US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Regional Banks Select Industry Index delivers modified equal-weight exposure to U.S. Regional Banks from the S&P Total Market Index. Additions must meet float-adjusted market-cap and liquidity requirements: either ≥ USD 500m with float-adjusted liquidity ratio (annual dollar value traded ÷ float-adjusted market cap) ≥90%, or USD 400–500m with ratio ≥150%; existing members must maintain ≥50% liquidity ratio and ≥ USD 300m float-adjusted market cap. At each quarterly rebalance, constituents are set to equal weights, then adjusted so no name exceeds its “maximum basket liquidity weight,” and finally constrained by a 4.5% single-name cap with excess redistributed iteratively. Membership is reviewed and weights are reset quarterly after the close on the third Friday of March, June, September, and December.


State Street SPDR S&P Pharmaceuticals ETF (XPH US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Pharmaceuticals Select Industry Index targets U.S.-listed companies classified in the Pharmaceuticals sub-industry of the S&P Total Market Index. Eligibility requires U.S. domicile within the parent universe and investability screens: new additions must have float-adjusted market cap ≥ USD 500m with float-adjusted liquidity ratio (annual dollar value traded ÷ float-adjusted market cap) > 90%, or ≥ USD 400m with liquidity > 150%; existing members must remain ≥ USD 300m and liquidity > 50%. The index seeks at least 35 names; if needed it may add highly correlated supplementary sub-industries to reach this count. Constituents are reweighted quarterly on a modified equal-weight basis with liquidity caps set so a single day’s trading can accommodate the basket (theoretical portfolio value USD 500m–2bn). Rebalancing occurs quarterly (March/June/September/December) using the second Friday’s close as the reference price.


State Street SPDR S&P Oil & Gas Exploration & Production ETF (XOP US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Oil & Gas Exploration & Production Select Industry Index targets the oil & gas exploration and production segment of the S&P Total Market Index across the Integrated Oil & Gas, Exploration & Production, and Refining & Marketing GICS sub-industries. Eligibility requires U.S. listings in the S&P TMI and size/liquidity that meet either: float-adjusted market cap ≥ USD 500m with float-adjusted liquidity ratio (12-month dollar value traded ÷ float-adjusted market cap) ≥ 90%, or market cap ≥ USD 400m with the ratio ≥ 150%; existing members remain if market cap ≥ USD 300m and the ratio ≥ 50%. The index seeks ≥35 constituents; if the primary sub-industry yields fewer names, additional eligible stocks from related sub-industries are included. Constituents are equal-weighted and reconstituted/rebalanced quarterly. Corporate actions are reflected per S&P DJI’s standard index maintenance rules.


State Street SPDR S&P Oil & Gas Equipment & Services ETF (XES US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P Oil & Gas Equipment & Services Select Industry Index provides exposure to U.S.-listed companies in the Oil & Gas Equipment & Services and Oil & Gas Drilling sub-industries of the S&P Total Market Index. Additions must satisfy investability screens: float-adjusted market cap ≥ USD 500m with float-adjusted liquidity ratio > 90%, or ≥ USD 400m with liquidity > 150%; existing members must remain ≥ USD 300m and liquidity > 50%. The index targets at least 35 constituents; if the primary sub-industries fall short, highly correlated supplementary sub-industries can be tapped to reach count, with relaxed thresholds permitted to keep ≥22 names. Weighting is modified equal weight with per-stock liquidity caps calibrated so a single day’s trading can rebalance a USD 500m–2bn model basket. Rebalanced quarterly (Mar/Jun/Sep/Dec) using the second Friday close as the reference price.


State Street SPDR S&P 400 Mid Cap Value ETF (MDYV US) – Portfolio Construction Methodology

Aug 6th, 2026 | By

The underlying S&P MidCap 400 Value Index targets the value style segment of the committee-maintained S&P MidCap 400, whose constituents typically fall in the mid-cap size range (generally about USD 3–15 billion at selection, adjusted over time). From the S&P MidCap 400 universe, each company receives growth and value scores; the value score combines book-to-price, earnings-to-price, and sales-to-price. Stocks are allocated proportionally between value and growth; a company may appear in both style indices with weights reflecting its style split. The value index weights constituents by float-adjusted market cap scaled by each constituent’s value allocation, then normalized. Style maintenance occurs in an annual December reconstitution using the latest fundamentals, with quarterly updates for shares and free float and standard corporate-action adjustments. No explicit single-name or sector caps are applied; concentration reflects the mid-cap universe and style tilts.
