In plain English
Boost Issuer PLC 2025-30.11.62 on PHLX Semiconductor Sector Gross Total Exchange Traded Product is an exchange-traded product from WisdomTree, launched in 2025.
It aims to deliver a multiple, or the opposite, of one day’s move in what it tracks. The multiple resets daily, so over longer periods its return can differ a lot from the multiple of the index return.
You buy and sell it through a share-dealing account or platform during stock-market hours, like a share.
Its ongoing charge is 4.49% a year — about £449 a year on every £10,000 invested, taken from the fund's value rather than billed to you.
Leveraged & inverse: Products that multiply or reverse a single day’s move — for example three times the daily change of an index.
