How NB Bancorp, Inc.’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.
Not offered: rated Sell.
We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.
Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.
For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.
Not offered: no liquid put and call pair for the same expiry.
For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.
General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.
