The ProShares UltraShort Silver fund aims to deliver daily investment returns that effectively track twice the inverse (-2x) of the Bloomberg Silver SubindexSM's daily performance. This objective is stated prior to the deduction of any fees and expenses.
ZSL (ProShares - UltraShort Silver) trades in the Financial Services sector, specifically Asset Management - Leveraged, with a market capitalization of approximately $59.3M, a beta of -1.90 versus the broader market, a 52-week range of 14.4-241.3, average daily share volume of 4.9M, a public-listing history dating back to 2008. These structural characteristics shape how ZSL etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on ZSL?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
ZSL snapshot
As of August 14, 2026, spot at $24.76, ATM IV 86.05%, IV rank 29.47%, expected move 24.67%. The butterfly on ZSL below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 28-day expiry.
Why this butterfly structure on ZSL specifically: ZSL IV at 86.05% is on the cheap side of its 1-year range, which favors premium-buying structures like a ZSL butterfly, with a market-implied 1-standard-deviation move of approximately 24.67% (roughly $6.11 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ZSL expiries trade a higher absolute premium for lower per-day decay. Position sizing on ZSL should anchor to the underlying notional of $24.76 per share and to the trader's directional view on ZSL etf.
ZSL butterfly setup
The ZSL butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ZSL at $24.76 on that close, the first option leg uses a $24.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ZSL chain at a 28-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 ZSL shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $25.00 | $2.03 |
| Buy 1 | Call | $26.00 | $1.53 |

When traders use butterfly on ZSL
Butterflies on ZSL are pinning bets - traders use them when they expect ZSL to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
ZSL thesis for this butterfly
The market-implied 1-standard-deviation range for ZSL extends from approximately $18.65 on the downside to $30.87 on the upside. A ZSL long call butterfly is a pinning play: it pays maximum at the middle strike if ZSL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ZSL IV rank near 29.47% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on ZSL at 86.05%. As a Financial Services name, ZSL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ZSL-specific events.
ZSL butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. ZSL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ZSL alongside the broader basket even when ZSL-specific fundamentals are unchanged. Always rebuild the position from current ZSL chain quotes before placing a trade.
