The words on this page
- Buffer
- The first slice of loss the fund absorbs for you over its outcome period, stated on the reference index. A 15% buffer means the index can fall 15% before you take any of it.
- Cap
- The most the fund can return over the period, however far the index rises. It is the price paid for the buffer.
- Outcome period
- The window the buffer and cap apply over, usually a year. Both are set at the start and only hold if you are there for the whole of it.
- Reset
- The day one outcome period ends and the next begins, with a fresh buffer and a fresh cap struck at that day’s level.
- Protection left
- The part of the buffer still below today’s index level. A buffer bought mid-period is not the full buffer; this is what is left of it.
