Rolling a position
Rolling is how options traders keep a position alive instead of simply closing it. To roll is to close your current option and open a new one at the same time — usually at a different expiration, a different strike, or both. It is the single most common adjustment in options trading.
The three directions of a roll
- Rolling out (in time). Close the near option, open a later-dated one at the same strike. You buy more time — often for a net credit, because the later option is worth more. Used to give a thesis longer to work or to defer assignment.
- Rolling up or down (in strike). Move the strike to a more favorable level — up for calls in a rising market, down for puts in a falling one. This adjusts your risk and breakeven.
- Rolling out and up/down (both). The most common defensive roll: move to a later date and a better strike at once, usually structured to bring in a credit or at least reduce the debit.
You sold a $105 call against stock now trading at $107 — it’s in-the-money and you’re about to be assigned and lose the shares. You don’t want to sell yet. You roll out and up: buy back the $105 call and sell a later-dated $110 call. If the later $110 call brings in more premium than the $105 cost to close, you roll for a net credit — raising your ceiling to $110, keeping the stock, and getting paid to do it. If it can’t be done for a credit, that’s the market telling you the roll isn’t free — sometimes taking assignment is the better choice.
When rolling helps — and when it doesn’t
Rolling is powerful for giving a trade more time or adjusting a strike that’s been breached, ideally for a credit. But it is not a way to avoid a loss forever. Each roll is a new trade that should stand on its own merits. “Rolling for a credit” feels like winning, but if you’re repeatedly rolling a losing position down and out, you may just be financing a bad trade and enlarging the eventual loss. Roll when the new position is one you’d put on fresh — not merely to postpone admitting defeat.
Rolling and volatility
The credit you collect on a roll depends heavily on implied volatility. Rolling into elevated volatility pays more; rolling when volatility is low pays little. A read on where implied volatility sits — the kind the Nations indexes provide — tells you whether the roll you’re considering is being generously or stingily priced.
Common pitfalls
Rolling losers indefinitely. Endlessly rolling a bad position out and down can turn a small, defined loss into a large one. Have an exit, not just a roll.
Ignoring transaction costs. Every roll is two trades. Frequent rolling racks up commissions and slippage that eat into the credits.
What to do with this
Treat each roll as a fresh trade: would you open this new position today? If yes, and preferably for a credit, roll. If no, close and move on. Knowing how big any of these positions should be is the next discipline: position sizing.
Rolling manages a trade you already have. Position sizing decides how big that trade should have been in the first place.
