Is TLT a good cash-secured put candidate?

TLT (iShares 20+ Year Treasury Bond ETF) 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 TLT 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 TLT cash-secured put

For TLT cash-secured puts, target strikes 7-10% below the current price at deltas of 0.20-0.30. Use 30-45 DTE — the sweet spot for theta-to-gamma balance. The rule is simple: only sell a put at a strike where you would genuinely be happy owning 100 shares, because on a moderate-volatility ticker you will occasionally get assigned.

Expected premium and income on TLT

Typical monthly premium collected on TLT runs around 1.0-2.0% of capital, which annualizes to roughly 12-24% if you sell new contracts every cycle. Capital required to run a single contract wheel on TLT is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.

Risk management for TLT 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. TLT moves in a moderate-volatility range most of the time, but earnings week and sector rotations can still produce 5%+ single-day prints. 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.
