TBT Cash-Secured Put: Strike Selection, Premium & Risk
How to sell cash-secured puts on ProShares UltraShort 20+ Year Treasury — optimal strikes, expected premium, and the risks that actually matter for a small-cap etf name.
Is TBT a good cash-secured put candidate?
TBT (ProShares UltraShort 20+ Year Treasury) is one of the most heavily traded ETFs for options strategies. Tight spreads and good open interest across strikes make it ideal for premium sellers. Because TBT 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 TBT cash-secured put
For TBT cash-secured puts, target strikes 10-15% below the current price at deltas of 0.15-0.25. Use 21-35 DTE to capture IV without excess gamma risk. The rule is simple: only sell a put at a strike where you would genuinely be happy owning 100 shares, because on a high-volatility ticker you will occasionally get assigned.
Expected premium and income on TBT
Typical monthly premium collected on TBT runs around 2.0-3.5% of capital, which annualizes to roughly 24-42% if you sell new contracts every cycle. Capital required to run a single contract wheel on TBT is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for TBT 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. TBT's high-volatility profile means 3-6% daily moves are normal during earnings or macro catalysts. 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.

How much cash do I need to sell a put on TBT?
Cash required is 100 × strike price. For TBT, that's roughly under $5,000 per contract at a typical strike. Most brokers let you use margin, but for a true cash-secured put you set aside the full amount.

Is TBT suitable for beginners selling options?
Not ideal for beginners. Smaller-cap names can have wider spreads and sharper moves. Start with large caps or major ETFs first. Always check the bid/ask spread before entering — anything wider than 5% of the mid price is a warning sign.
