How much of the same holdings they own

SPYM and VOO share 96.03% of their weighted exposure across 500 common holdings.

6 holdings are unique to SPYM, and 5 holdings are unique to VOO. Owning both adds little diversification — they are largely the same exposure in different wrappers.

SPYM is the more concentrated of the two: its ten largest positions are 38.1% of the fund, against 37.65% for VOO (508 holdings vs 508). Concentration cuts both ways — it is what drives outperformance when the top names work, and what makes the drawdown deeper when they do not.

How this comparison is scored

The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.

The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
