What Happens When You Get Assigned Shares

In short

What actually happens to your account on assignment — reserved cash converting into shares at your strike — with a step-by-step worked example.

Getting assigned on a cash-secured put isn't an alarm bell — it's step three of the wheel, working exactly as designed. Here's exactly what happens to your account when it occurs.

The mechanics of assignment

Assignment simply converts the cash you reserved into shares, at the strike price you already agreed to. Nothing about the wheel changes course — this is the cycle from the first lesson playing out as planned.

A worked example

You sold a $50-strike put on XYZ, 30 days out, for $1.20 premium, with $5,000 held as collateral. XYZ closes at $47 on expiration day.

Before assignment	After assignment
$5,000 cash (reserved)	100 shares of XYZ, purchase price $50/share (before premium adjustment)
Short 1 put contract	No open option position
$120 premium already collected	Still yours, unaffected

Overnight, cash and an obligation become stock. Your broker handles this automatically — you don't place a new buy order; the assignment itself is the purchase.

Your real cost is lower than the strike

The $50 strike is what you pay per share, but it isn't your true cost once the premium is counted. Having collected $1.20/share, your effective cost basis is $48.80 — a number worth its own full lesson next.

What doesn't change

Assignment doesn't create a new decision about whether you want the shares — that decision was made the moment you chose to sell a put on a stock you'd be willing to own, at a strike you'd be willing to pay. It's the mechanical conclusion of a choice made in advance, not a fresh judgment call.

Trade with discipline

Once assigned, your risk shifts to ordinary stock ownership — if XYZ keeps falling, those losses are real, the same as for anyone who bought the stock outright at $50. The premium softens the decline; it doesn't insulate you from it. Assignment should never come as a surprise if you only sold puts on stock you'd genuinely be willing to hold through a downturn — which is exactly why knowing your strike, expiration, and max risk before you enter matters so much.

Key takeaway: Assignment converts your reserved cash into shares at the strike you already agreed to — a planned step in the wheel, not a mistake.

Next: how to calculate your real cost basis after assignment, and why it matters for every decision that follows.
