RUN (Sunrun Inc.) trades in the Energy sector, specifically Solar, with a market capitalization of approximately $3.45B, a trailing P/E of 5.97, a beta of 2.25 versus the broader market, a 52-week range of 5.38-22.44, average daily share volume of 10.1M, a public-listing history dating back to 2015, approximately 11K full-time employees. These structural characteristics shape how RUN stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 2.25 indicates RUN has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 5.97 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.
What is a long put on RUN?

Current RUN snapshot
As of May 15, 2026, spot at $14.12, ATM IV 71.98%, IV rank 14.73%, expected move 20.64%. The long put on RUN 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 28-day expiry.
Why this long put structure on RUN specifically: RUN IV at 71.98% is on the cheap side of its 1-year range, which favors premium-buying structures like a RUN long put, with a market-implied 1-standard-deviation move of approximately 20.64% (roughly $2.91 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 RUN expiries trade a higher absolute premium for lower per-day decay. Position sizing on RUN should anchor to the underlying notional of $14.12 per share and to the trader's directional view on RUN stock.
RUN long put setup
The RUN long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With RUN near $14.12, the first option leg uses a $14.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RUN 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 RUN shares for the stock leg in covered calls and collars).

RUN thesis for this long put
The market-implied 1-standard-deviation range for RUN extends from approximately $11.21 on the downside to $17.03 on the upside. A RUN long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long RUN position with one put per 100 shares held. Current RUN IV rank near 14.73% 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 RUN at 71.98%. As a Energy name, RUN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RUN-specific events.
RUN long put positions are structurally 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. RUN positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RUN alongside the broader basket even when RUN-specific fundamentals are unchanged. Long-premium structures like a long put on RUN 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 RUN chain quotes before placing a trade.
