Overview
The State Street SPDR S&P MIDCAP 400 ETF Trust, trading under the ticker MDY, operates within the US Mid Cap category managed by State Street Investment Management. This fund tracks 14 ETFs in its specific category and holds an overall rank of #202 out of 458 tracked ETFs across all sectors. It carries an ETFValuer grade of C with a score of 62.4 out of 100, reflecting its current standing relative to peers. The fund charges an expense ratio of 0.23% and offers a dividend yield of 0.98% to income-seeking investors. With assets under management totaling $28.1 billion and a share price of $692.97, the ETF demonstrates significant investor adoption and liquidity. These metrics position the fund as a substantial vehicle within the mid-cap space despite its mid-tier overall ranking.
Short-term performance shows mixed results with a slight gain of +0.02% over one day and +0.37% over one week, followed by a decline of -0.33% in the last month. The fund has accelerated into longer horizons, posting a 3-month return of +4.50% and a 6-month return of +9.53%. Year-to-date performance stands at +13.92%, while the one-year return has reached +19.23%. Over a three-year period, the fund has generated a cumulative return of +46.26%, indicating sustained growth over the medium to long term. This trajectory suggests a divergence where recent short-term volatility has given way to stronger momentum over the past year and beyond.
The fund is classified with a Moderate volatility label and exhibits a beta of 0.99, suggesting its price movements generally align closely with the broader market. A Sharpe ratio of 0.91 indicates a reasonable risk-adjusted return profile relative to the volatility experienced. However, the maximum drawdown of -24.03% highlights the potential for significant temporary losses during market downturns. This combination of a near-unity beta and moderate volatility implies the fund mirrors market swings without excessive amplification. The substantial drawdown figure underscores that while risk-adjusted returns are positive, the fund remains exposed to deep corrections typical of mid-cap equities.

MDY Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is — and average daily volume is 685K/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $28.1B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: MDY is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
