BELFB (Bel Fuse Inc.) trades in the Technology sector, specifically Hardware, Equipment & Parts, with a market capitalization of approximately $3.38B, a trailing P/E of 59.96, a beta of 1.42 versus the broader market, a 52-week range of 69-308.27, average daily share volume of 189K, a public-listing history dating back to 1998, approximately 5K full-time employees. These structural characteristics shape how BELFB stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on BELFB?
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.
Current BELFB snapshot
As of May 15, 2026, spot at $259.33, ATM IV 48.30%, IV rank 42.89%, expected move 13.85%. The butterfly on BELFB 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 butterfly structure on BELFB specifically: BELFB IV at 48.30% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 13.85% (roughly $35.91 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 BELFB expiries trade a higher absolute premium for lower per-day decay. Position sizing on BELFB should anchor to the underlying notional of $259.33 per share and to the trader's directional view on BELFB stock.
BELFB butterfly setup
The BELFB butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BELFB near $259.33, the first option leg uses a $250.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BELFB 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 BELFB shares for the stock leg in covered calls and collars).

BELFB thesis for this butterfly
The market-implied 1-standard-deviation range for BELFB extends from approximately $223.42 on the downside to $295.24 on the upside. A BELFB long call butterfly is a pinning play: it pays maximum at the middle strike if BELFB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BELFB IV rank near 42.89% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BELFB should anchor more to the directional view and the expected-move geometry. As a Technology name, BELFB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BELFB-specific events.
BELFB 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. BELFB positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BELFB alongside the broader basket even when BELFB-specific fundamentals are unchanged. Always rebuild the position from current BELFB chain quotes before placing a trade.
