BRK.B Cash-Secured Put: Strike Selection, Premium & Risk
How to sell cash-secured puts on Berkshire Hathaway Inc. Class B — optimal strikes, expected premium, and the risks that actually matter for a mega-cap financial name.
Is BRK.B a good cash-secured put candidate?
BRK.B (Berkshire Hathaway Inc. Class B) is a mega-cap financial name with an elevated share price and excellent options liquidity. Implied volatility is low, so premiums are modest. Traders use this name when they want stability and a low probability of assignment rather than maximum yield. It pays no dividend, so every dollar of income must come from the options you sell.
Strike selection for a BRK.B cash-secured put
For BRK.B cash-secured puts, target strikes 5-7% below the current price at deltas of 0.25-0.35. Use 30-45 DTE (theta decays slow, so longer dated). The rule is simple: only sell a put at a strike where you would genuinely be happy owning 100 shares, because on a low-volatility ticker you will occasionally get assigned.
Expected premium and income on BRK.B
Typical monthly premium collected on BRK.B runs around 0.5-1.0% of capital, which annualizes to roughly 6-12% if you sell new contracts every cycle. Capital required to run a single contract wheel on BRK.B is $20,000+ — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for BRK.B 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. BRK.B is a low-volatility name — the main risk is not sudden moves but slow grinds against you, which hurt covered-call writers who picked strikes too close to the money. Financials are sensitive to the yield curve, credit spreads, and Fed decisions; rate-decision days frequently produce outsized moves.
