Current KSTR snapshot

As of June 29, 2026, spot at $30.65, ATM IV 55.70%, IV rank 44.02%, expected move 15.97%. The bear put spread on KSTR 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 18-day expiry.

Why this bear put spread structure on KSTR specifically: KSTR IV at 55.70% 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 15.97% (roughly $4.89 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated KSTR expiries trade a higher absolute premium for lower per-day decay. Position sizing on KSTR should anchor to the underlying notional of $30.65 per share and to the trader's directional view on KSTR etf.

KSTR bear put spread setup

The KSTR bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KSTR near $30.65, the first option leg uses a $31.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KSTR chain at a 18-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 KSTR shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$31.00	$1.58
Sell 1	Put	$29.00	$0.98

A KSTR bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on KSTR, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit.

As a Financial Services name, KSTR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KSTR-specific events.

KSTR bear put spread positions are structurally moderately bearish; 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. KSTR positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move KSTR alongside the broader basket even when KSTR-specific fundamentals are unchanged. Long-premium structures like a bear put spread on KSTR are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current KSTR chain quotes before placing a trade.
