Is UNG a good cash-secured put candidate?

UNG (United States Natural Gas Fund) is one of the most heavily traded ETFs for options strategies. Penny-wide bid/ask spreads and deep open interest on every strike make it ideal for premium sellers. Because UNG is a basket rather than a single name, single-stock earnings risk is diffused, which is a meaningful edge for consistent income.

Strike selection for a UNG cash-secured put

For UNG 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 UNG

Typical monthly premium collected on UNG 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 UNG is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.

Risk management for UNG 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 UNG, expect 5-10%+ single-day moves during stress. Size positions so one adverse gap doesn't blow up the account. ETFs diffuse single-stock risk but still carry basket-level exposure — a sector ETF will move on macro shocks even if individual holdings are fine.
