Below the strike, a sold put is stock

The homework was done. The business was one you were willing to own, the strike sat below the price, the calendar was clean, and there was no earnings report inside the window. Then the stock fell anyway. Not in a gap, not through an earnings report. It simply kept falling, and one afternoon it closed through the strike and did not come back.

That morning is the subject of this article. Not whether the put should have been sold: that question was answered before the order went in, and it stays answered. The question now is what you are holding, and what can be done about it.

What a sold put becomes below its strike

Above its strike, a sold put is a claim on time. It loses a little when the stock dips, it gains as the days pass, and if the stock is still above the strike at expiration, it expires and the premium is kept.

Below its strike it becomes something else. For every dollar the stock falls, the put costs you a dollar more. Deep below the strike, a sold put is a long position in the stock in everything but name. You carry the full downside without owning a share, and time has stopped helping you.

Below the strike, your short put is 100 shares you never bought.

Seen that way, the problem on the morning the strike breaks is an old one. You are long a stock that is going down. What neutralizes a long stock position, quickly, and at a price you can see before you pay it?

There is a tool for that morning

The third pillar of our method, active trade defense, has one tool built for exactly this case: a short position built from options, placed at the strike of the put you sold. Below the strike the two positions cancel, and whatever the stock does from there on the downside, the loss does not change. We call it a lock, because the loss is locked where it stands. It needs a margin account, and where it is placed is most of the technique.

It is not free. Every lock costs the distance between the strike and the fill, plus the spread on four option legs, and a lock that has to come off again, because the stock climbed back above the strike, costs the crossing too. On a stock that closes through its strike and keeps going, those costs are small. On a stock that crosses its strike again and again, they add up until they exceed the premium. In our own record, on another name and at a strike placed differently, the same tool made the position worse, not better. Which name, and which strike, is the entire skill.

And it has limits. A lock left on through a rebound becomes a different risk of its own. A gap through the strike leaves nothing to lock cheaply. It needs real-time attention during US market hours and the ability to act within 30 to 60 minutes. If you trade in a cash account, the lock itself is not available to you, but the shape of the lesson is: a line decided before the trade, a trigger you can read off a chart, and a cost you can estimate before you act.

If you want the tool

The free guide, When the Stock Breaks Your Strike, shows it on one real trade from our own record: a put sold on a business we were willing to own, twenty-nine trading days that went the wrong way, the moment on the chart where the lock would have gone on, and what it would have cost, before and after spreads. Seven pages, with the arithmetic, the two crossings, and the situations where it must not be used.
