Funds that reset every day

Holding a 2x, 3x or inverse fund?

These funds aim for a multiple of one day's move, then start over the next day. Held for weeks, they can lose money even when the index ends about flat. Type the index's daily moves and see it on your own numbers.

What the fund ends at

It starts with the SEC's own example: the index falls 10% one day and rises 10% the next. Change it to any days you like.

A bumpy stretch goes down, then up by the same percent, day after day. These numbers stay in this page's memory only.

How we count: each day the index moves by its percent and the fund moves by the multiple times that percent, and both compound from one day to the next. "Many expect" is the multiple times the index's change over all the days. A day that would take the fund to zero counts as wiped out. Fees, borrowing costs and days a fund misses its own target are left out, and they usually make the result worse.
