MDYG State Street SPDR S&P 400 Mid Cap Growth ETF

State Street SPDR S&P 400 Mid Cap Growth ETF (MDYG) currently reports 241 stock positions (subject to change), placing it in the widely spread range by holdings breadth. The top line-up is FLEX (3.21%), TWLO (1.90%), FTI (1.54%), with FLEX as the largest single weight at 3.21%. Together, the top three holdings account for 6.65%, which points to a relatively flat weight distribution where no single cluster of names dominates outcomes. The weight distribution suggests a portfolio designed to capture thematic upside while avoiding excessive dependence on any single name outside the largest positions.

Assessing the quality of returns on invested capital, ROIC is 19.41%, WACC is 9.63%, and the economic spread is 9.79%. On balance, the economic spread is thin but positive — the portfolio's businesses are clearing the hurdle, though without significant headroom. Supporting metrics show ROE at 20.00% and ROA at 6.69%, a combination that helps frame whether profitability strength is broad enough to hold through different market conditions. Taken together, the return profile suggests a portfolio that is value-creative but with less room for execution slippage.

The market currently prices the portfolio at trailing P/E of 29.10, forward P/E of 21.65, PEG of 2.08. The trailing and forward multiples diverge by a moderate amount, consistent with a market that sees improving earnings but is not extrapolating an aggressive growth path. The PEG ratio is consistent with a portfolio that is reasonably valued on a growth basis — not cheap, but not obviously expensive either. At 2.96, the aggregate current ratio reflects strong balance sheet liquidity across the portfolio. Valuation and liquidity together frame a portfolio where the price paid today is a reasonable bet on earnings delivery — but not a margin-of-safety purchase at current levels.

Looking at margins from gross to free cash flow, gross margin sits at 46.66%, operating margin at 16.47%, and free cash flow margin at 16.68%. Gross margins are constructive — not exceptional, but indicative of businesses with reasonable unit economics. At this level, operating margins reflect businesses that are scaling with discipline without dramatic cost pressure. The portfolio's cash conversion is solid — a sign that operating profits are translating into real liquidity at the fund level. Together, these margins describe a portfolio where business quality varies — and where macro or sector headwinds could disproportionately impact the weaker-margin holdings.

Projected 12-month EPS growth of 34.4% adds a powerful forward signal — analyst consensus expects earnings to accelerate materially, which, if delivered, could make current multiples look increasingly modest. Turning to growth and analyst expectations, TTM revenue growth of 24.00% pointing to sustained and broad-based revenue growth within the basket, while the estimated 12-month price change of 18.84%, where target prices point to mid-range appreciation potential from current levels. The distinction matters: revenue growth tells you what the businesses are doing, price targets tell you what analysts think the market will pay for it. Ultimately, the alignment between revenue momentum and analyst targets will depend on execution quality and the broader rate and sentiment environment. The estimated 12-month price change is a weighted composite of analyst price target estimates adjusted by each holding's ETF weight, sourced from publicly available data, and should not be interpreted as a reliable prediction of future performance.

The quantitative profile, taken as a whole, is above average on virtually every dimension that matters for long-term return generation.
