Latest News for MFSX
No articles mention this fund directly in the last 7 days; showing general ETF coverage.
Guided help: AUM is fund size. The expense ratio is the yearly cost baked into returns. NAV is the value of what the fund owns per share; the market price can sit slightly above (premium) or below (discount) it. Total return assumes distributions were reinvested. Every dataset shows its own as-of date because holdings, assets and quotes update on different schedules.
