Realized vs theoretical +2x Bitcoin

Cumulative return of BTCU against a clean +2x of Bitcoin's return over the same window; the red line (right axis) is the gap between them.

Pair counterpart: SBIT (-2x bear, ProShares UltraShort Bitcoin ETF)

Shorting both legs of a daily-reset bull/bear pair captures their combined decay over time. It isn't free money — the edge depends on borrow rates (often punitive on the bear leg) and assignment risk on hard-to-borrow shares.

How BTCU works

BTCU targets +2x the daily return of Bitcoin — not the return over longer windows. It rebalances every day, so over weeks and months its result drifts away from +2x × the index, usually downward when the market chops around.

The maths: the drag is roughly −½ × N × (N−1) × σ² per period (N = leverage, σ = the index's volatility). For a +2x fund on an index with 25% annual volatility that is several percent a year before fees — the red line above is that drag measured.

Short-term trades (a day or a few) are what these funds are built for. Premium sellers like their rich option IV — see the quote page. Multi-day directional bets work in strong trends and get eaten in chop.
