SIZE Strangle Strategy
SIZE (iShares MSCI USA Size Factor ETF), in the Financial Services sector, (Asset Management industry), listed on AMEX.
The iShares MSCI USA Size Factor ETF seeks to track the investment results of an index composed of U.S. large- and mid-capitalization stocks with relatively smaller average market capitalization.
SIZE (iShares MSCI USA Size Factor ETF) trades in the Financial Services sector, specifically Asset Management, with a market capitalization of approximately $408.5M, a beta of 0.99 versus the broader market, a 52-week range of 146.58-173.02, average daily share volume of 7K, a public-listing history dating back to 2013. These structural characteristics shape how SIZE etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.99 places SIZE roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. SIZE pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a strangle on SIZE?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current SIZE snapshot
As of May 15, 2026, spot at $169.98, ATM IV 14.60%, IV rank 16.21%, expected move 4.19%. The strangle on SIZE below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this strangle structure on SIZE specifically: SIZE IV at 14.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a SIZE strangle, with a market-implied 1-standard-deviation move of approximately 4.19% (roughly $7.11 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SIZE expiries trade a higher absolute premium for lower per-day decay. Position sizing on SIZE should anchor to the underlying notional of $169.98 per share and to the trader's directional view on SIZE etf.
SIZE strangle setup
The SIZE strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SIZE near $169.98, the first option leg uses a $180.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SIZE chain at a 34-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 SIZE shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $180.00 | $0.19 |
| Buy 1 | Put | $161.00 | $1.18 |

When traders use strangle on SIZE
Strangles on SIZE are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the SIZE chain.
SIZE thesis for this strangle
The market-implied 1-standard-deviation range for SIZE extends from approximately $162.87 on the downside to $177.09 on the upside. A SIZE long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current SIZE IV rank near 16.21% 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 SIZE at 14.60%. As a Financial Services name, SIZE options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SIZE-specific events.
SIZE strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. SIZE positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SIZE alongside the broader basket even when SIZE-specific fundamentals are unchanged. Always rebuild the position from current SIZE chain quotes before placing a trade.
