SPY4 gives similar asset-class exposure, but it is not a like-for-like index match.
What is SPY4?
SPY4 is SPDR S&P 400 US Mid Cap UCITS ETF, a UCITS-compliant ETF that BestFolio uses when translating MIDU into a European-broker-friendly allocation. UCITS funds are designed for EU and UK retail access and carry the required investor documents that US-listed ETFs usually lack.
MIDU = 3x S&P MidCap 400. No leveraged MidCap UCITS exists. SPY4 = 1x S&P 400 (correct index, no leverage). Consider 3x position sizing. The source ticker has 3x exposure and the UCITS substitute has 1x exposure, so BestFolio can flag leverage differences during allocation translation.
