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.
The most the fund can return over the period if held from the first day to the last. Quoted gross and net of fees. Set by the option market on day one, so the same fund can have a different cap each year.
The window, usually twelve months and sometimes six or three, over which the cap and buffer apply. On its last day the options expire, the fund resets, and a new cap is struck from that day’s option prices.
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.
How much of the buffer still sits below today’s index level. All of it when the index is above its starting level; less once the index is inside the buffer range.
