Collar

Own stock, buy a protective put, sell a covered call. Cap both downside and upside for low or zero net cost.

A collar wraps your stock position in two options: a protective put below and a covered call above. The call premium funds the put purchase, often for zero net cost. You give up unlimited upside in exchange for a hard floor under your position. It’s the strategy for investors who want to hold their stock but can’t stomach another drawdown.

Outlook
Mildly bullish with protection. Willing to cap upside to fund downside.
Legs
2 (long OTM put, short OTM call; stock implicit)
Max loss
Defined: stock price − put strike + net cost
Max profit
Defined: call strike − stock price − net cost
IV preference
Moderate. Higher IV makes the sold call richer, funding the put.
Best regime
Uncertain market where you want to hold stock but sleep at night.

The structure

A collar is the combination of two strategies you may already know: a covered call and a married put. For every 100 shares you own:

  • Buy one OTM put — this is your floor. No matter what happens, you can sell at the put strike.
  • Sell one OTM call — this is your ceiling. If the stock rallies past the call strike, your shares get called away.

The key insight is that both options are on the same expiration, and the call premium offsets (or completely pays for) the put. When the net cost is zero, traders call it a “zero-cost collar.”

Worked example

You own 100 shares of AAPL at $185. Markets are jittery and you want protection through the next earnings cycle. The 30 DTE collar:

  • Buy the $175 put for $3.00
  • Sell the $195 call for $3.50
  • Net credit: $0.50 ($50 per collar)
  • Max loss: $185 − $175 − $0.50 = $9.50 per share ($950)
  • Max profit: $195 − $185 + $0.50 = $10.50 per share ($1,050)
  • Breakeven: $185 − $0.50 = $184.50 (slightly below current price)

If AAPL drops to $160, the put protects you — your effective sale price is $175 plus the $0.50 credit, so you lose $9.50 per share instead of $25. If AAPL rallies to $210, your shares are called away at $195 and you pocket $10.50 per share total. In between, you hold the stock as usual and keep the $0.50 credit.

When to use it

  • Holding stock through uncertainty. Earnings season, macro events, geopolitical risk — any time you want the position but not the tail risk.
  • Earnings protection. Collars are particularly popular around earnings when a stock could gap 10% either way. The collar lets you stay long through the event without the gut punch of a miss.
  • Zero-cost hedge.When the call premium matches or exceeds the put cost, you get downside protection for free. This is the collar’s killer feature and the reason institutions use it constantly.
  • Tax-lot management. If selling the stock would trigger a large capital gain, a collar lets you hedge without selling. You keep the position, defer the tax event, and still sleep at night.

How Tradient ranks them

The collar scanner walks your watchlist and, for each position, finds OTM put/call pairs in the DTE window that produce either a net credit or a net debit below your threshold. Tradient defaults to zero-cost or credit collars and sorts by the width of the profit zone (call strike minus put strike).

The Tradient Score layer gives extra weight to collars where the call delta is lower than the put delta — meaning you’re getting more downside protection than you’re giving up in upside. That asymmetry is the hallmark of a well-constructed collar.

Managing the trade

Call is approaching the strike

If the stock rallies toward the call strike with time left, you have two choices: let assignment happen and take the capped gain, or roll the call up and out for a credit. Rolling works if you can collect net credit — never roll for a debit. If the stock has genuinely broken out, let the shares go and redeploy.

Put is being tested

If the stock drops toward the put strike, the protection is working as designed. The put gains value as the stock falls, offsetting your stock loss. At expiration, if the stock is below the put strike, exercise the put (or sell it and sell the stock separately if that’s more efficient).

The collar did its job
When the put triggers, don’t be frustrated that you “lost money.” You chose a defined-loss outcome over an unbounded one. The collar worked. Evaluate the position fresh and decide whether to re-collar at lower strikes or move on.

Stock stays in the corridor

If AAPL finishes between $175 and $195 at expiration, both options expire worthless and you keep the $0.50 credit plus whatever the stock did. This is the most common outcome and exactly what you want.

Common mistakes

  • Collaring stock you should just sell.If your thesis on the stock is dead, don’t collar it — sell it. The collar protects a position you still believe in; it’s not a life-support machine for a bad idea.
  • Too-tight collar choking upside.If the call strike is barely above the current price, the “protection” is mostly theoretical — you’re getting called away on any green day. Give the stock room to breathe. A 5-10% spread between current price and call strike is a reasonable starting point.
  • Paying too much net debit.The entire appeal of the collar is the cheap or free hedge. If you’re paying $3 for a collar on a $50 stock, re-examine whether the strike selection makes sense.
  • Ignoring dividends.The short call can be exercised early near an ex-dividend date. If the call is in the money before the ex-date, expect early assignment. Tradient’s Focus mode flags this scenario.
