Price and performance snapshot (14/10/2026)
E1VFVN30 slipped 0.15% in the session, 0.76% over the week and 2.90% over the month, leaving it down 6.37% year to date. FUEVFVND fell more sharply on the day at -1.14%, was comparatively steadier over the week at -0.37%, then widened the gap on the month at -4.42% and on the year at -16.40%.
That is the single most notable data point in the set: the year-to-date performance difference between the two funds is approximately ten percentage points. Over the one-month window the gap is narrower but still present — 2.90% versus 4.42%.
What the gap between E1VFVN30 and FUEVFVND actually shows
A performance gap between two ETFs is not, by itself, evidence of tracking error. The two funds track different reference indices with different construction rules, so a divergence in returns is expected behaviour rather than a defect. What matters for a tracking error assessment is how each fund performs against its own index — and that data is not contained in the price table above.
What the table does establish is that over the periods shown, the Diamond strategy has been the weaker of the two on a year-to-date basis, while both remain negative. Investors comparing the pair should treat the -6.37% versus -16.40% spread as a composition and strategy effect first, and only then ask whether tracking error is adding to it.
