Rolling a put: when and how

Why traders roll puts

The two situations:

Defense (most common). You sold a put. The underlying has dropped and now your strike is close to or above current price. You're nervous about assignment. Solution: close the current put (at a loss) and open a new one at a lower strike or later expiration, ideally for a net credit.

Profit-taking. The trade has worked. The put is now worth a fraction of what you sold it for. You could let it expire worthless, but the remaining profit per day is small and the gamma risk is rising. Solution: close the current put (at a profit) and sell a new one at a similar delta to maintain the income stream.

The three rolls

Roll out (same strike, later expiration)

Used when you still believe in the underlying but need more time. You'd be happy with assignment at the original strike but want to see if the stock recovers first.

Roll down (lower strike, same expiration)

Used when you want to reduce assignment probability by lowering your obligation. The cost is usually a debit (lower strike = lower premium), so it's a defensive move that locks in some loss.

Roll down and out (lower strike, later expiration)

The combination. Most common defensive roll. Lower strike reduces assignment probability; later expiration adds time premium to make the net a credit. The textbook defensive maneuver when the underlying has dropped.

When to actually roll

My triggers:

Roll for profit when:

• The put is worth 50% or less of what I sold it for, with at least 7 days remaining.
• The premium for the next cycle's CSP at the same delta would be meaningful enough to redeploy the capital.

Roll defensively when:

• The underlying has dropped to within 2-3% of my strike with at least 7 days remaining.
• I still want to own the underlying (just not at the original strike).
• The roll can be done for a net credit at a lower strike with reasonable extra time.

Don't roll, take assignment when:

• You'd be happy owning the shares at the original strike.
• The defensive roll requires a net debit (paying to delay a losing trade).
• Your thesis on the underlying has changed; you no longer want to own it. Take the loss, move on.

Worked defensive roll

Defensive roll: down to $190 strike, out to 45 DTE.

1. Buy back the $200 put: cost $750.
2. Sell the $190 put expiring in 45 days for $8 premium (credit $800).
3. Net credit: $50. Your strike is now $10 lower and you have 31 more days.

The net economic position: you've collected $300 (original) + $800 (new) = $1,100 against potential assignment at $190 (effective cost basis: $190 - $11 net premium per share = $179). NVDA is at $198. You've moved your assignment threshold $10 lower for $50 of additional credit. That's a good trade if you wanted to own NVDA at $179 (which is what we're effectively betting on).

Common rolling mistakes

Three to avoid:

1. Rolling for net debit. If you're paying to extend a losing position, the strategy doesn't work over time. Either take the assignment or close the loss.
2. Rolling without a thesis update. Each roll should reflect your current view. “The stock dropped, I'll just roll” isn't a strategy — it's avoidance. If your view of the underlying has changed, close the position.
3. Chasing the underlying down forever. If you've rolled 3 times and the stock keeps dropping, accept that the original entry was wrong. Take the loss; redeploy elsewhere.
