RUN Cash-Secured Put: Strike Selection, Premium & Risk
How to sell cash-secured puts on Sunrun Inc. — optimal strikes, expected premium, and the risks that actually matter for a mid-cap technology name.
Is RUN a good cash-secured put candidate?
RUN (Sunrun Inc.) is a mid-cap technology name with a low share price and good options liquidity. Implied volatility on this ticker is elevated, so option premiums are rich — but the same volatility cuts both ways and can move the stock hard in either direction. It pays no dividend, so every dollar of income must come from the options you sell.
Strike selection for a RUN cash-secured put
For RUN cash-secured puts, target strikes 15-20% below the current price at deltas of 0.10-0.20. Use 14-28 DTE so you can react to sharp IV crushes and moves. The rule is simple: only sell a put at a strike where you would genuinely be happy owning 100 shares, because on a very high-volatility ticker you will occasionally get assigned.
Expected premium and income on RUN
Typical monthly premium collected on RUN runs around 3.5-6.0% of capital, which annualizes to roughly 42-72% if you sell new contracts every cycle. Capital required to run a single contract wheel on RUN is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for RUN cash-secured put trades
The core risk on a cash-secured put is assignment into a falling stock: your break-even is the strike minus the premium, so a sharp drop below that level leaves you with unrealized losses on the assigned shares. On a very high-volatility name like RUN, expect 5-10%+ single-day moves during stress. Size positions so one adverse gap doesn't blow up the account. Tech names are especially vulnerable to interest-rate shifts and earnings guidance revisions — both tend to produce gap moves that hurt short options.
