What is WTEF?

WTEF is WisdomTree US Efficient Core UCITS ETF, the European-listed product BestFolio uses when translating NTSX. Most targets are UCITS ETFs; some commodity and leveraged targets are UCITS-eligible ETCs or ETPs instead. Product structure and retail eligibility must be checked for the exact ISIN.

NTSX = 90% S&P 500 + 60% Treasury futures (1.5x notional). WTEF is the issuer's own UCITS wrapper of the same 90/60 structure, LSE-listed since 2023-10-10 (WTEF.L in GBp, NTSX.L in USD), TER 0.20%. Held at full 1.5x, so no dilution: this is a like-for-like swap. "close" not "exact" because the UCITS index applies WisdomTree ESG exclusions (norms violators, controversial weapons, tobacco, thermal coal, unconventional oil and gas) that the US fund does not. Small fund (low tens of millions) with thin on-screen volume; mind the spread. Was wrongly mapped to a diluted CSPX+IBTM composite until #3278. The source ticker has 1.5x exposure and the mapped target has 1.5x exposure, so BestFolio can flag leverage differences during allocation translation.
