A beta of 0.74 places FDUS roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 8.54 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. FDUS pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on FDUS?

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 FDUS snapshot

As of May 15, 2026, spot at $18.77, ATM IV 253.80%, IV rank 68.81%, expected move 5.68%. The butterfly on FDUS 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 FDUS specifically: FDUS IV at 253.80% 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 5.68% (roughly $1.07 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 FDUS expiries trade a higher absolute premium for lower per-day decay. Position sizing on FDUS should anchor to the underlying notional of $18.77 per share and to the trader's directional view on FDUS stock.

FDUS butterfly setup

The FDUS 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 FDUS near $18.77, the first option leg uses a $17.83 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FDUS 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 FDUS shares for the stock leg in covered calls and collars).

FDUS thesis for this butterfly

The market-implied 1-standard-deviation range for FDUS extends from approximately $17.70 on the downside to $19.84 on the upside. A FDUS long call butterfly is a pinning play: it pays maximum at the middle strike if FDUS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FDUS IV rank near 68.81% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on FDUS should anchor more to the directional view and the expected-move geometry. As a Financial Services name, FDUS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FDUS-specific events.

FDUS 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. FDUS positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FDUS alongside the broader basket even when FDUS-specific fundamentals are unchanged. Always rebuild the position from current FDUS chain quotes before placing a trade.
