Trading Weekly Options on Friday

By Amanda Harvey · Updated October 15, 2026

Trading weekly options on Friday can mean closing a position that expires that day or trading a contract with a later expiration. Start with the contract's actual expiration date. A same-day option has very little time left, and its entire premium can be lost.

THE SIGNIFICANCE OF FRIDAY IN TRADING

Many US stock options expire on Fridays. Standard monthly expirations normally fall on the third Friday, with weekly series on other Fridays and adjustments for market holidays. Index and ETF schedules can differ. Check the Friday expiration calendar and the exact date in your broker's option chain.

HOW DO WE DEFINE TRADING?

This lesson focuses on buying a call or put and later selling that contract to close the position. That differs from exercising it, which can create a position in the underlying shares. WOU publishes researched alerts; the decision to enter or close a trade remains yours.

DAY TRADING WEEKLY OPTIONS ON FRIDAY

There are sometimes factors occurring on a Friday that are expected to cause a dramatic movement in the price of a stock and likewise, its corresponding weekly option. If an event coincides with expiration, the short time remaining can amplify the risk of a day trade. This means that a trader enters and then exits the trade within the same trading day. Less time remaining can reduce the time-value component of a premium, but it also leaves less time for the expected move. Stock-price changes and implied volatility still affect the price, so expiration-day options are not necessarily cheaper or better value.

Brokers can restrict opening positions on expiration day or close a position that an account cannot support. An order to close does not guarantee a fill. An in-the-money option still held at expiration may be exercised unless contrary instructions apply. Exercising a call means buying the underlying shares; exercising a put means selling them. Check your broker's rules, available funds and deadline for exercise instructions.

WAITING TO SELL ON EXPIRATION DAY

Another way to look at the concept of trading weekly options on Friday is to consider the scenario in which you have previously bought a weekly options contract, but are waiting until its Friday expiration date to sell it.

This may be because the price has already moved substantially, but is still continuing to climb, and you believe that waiting until Friday may give you an opportunity to realize a higher profit. A sale still needs a willing counterparty and a price at which the order can fill.

There are obviously some risks in taking this approach, as the price may not continue to rise, or you may be unable to sell the contract at the price you want, regardless of the market value.

HOLDING ON TO A LOSING POSITION

A purchased option can expire worthless, losing the premium paid. Holding it through expiration can also lead to an exercise and an underlying share position if it finishes in the money. Your broker may restrict or close a position where the account cannot support that outcome. Review its rules before the deadline.

By waiting until the last day with an under-performing options contract, you could possibly have the opportunity to make some profit, or at least break even if the price suddenly begins to rise (or fall in the case of a put).

OTHER SCENARIOS

If you are buying and/or selling weekly options contracts on a Friday that is not the expiration date of the option in question, there are not so many differences to trading at other times.

You might be buying and/or selling a weekly options contract that expires the following week, in which case, your trade would only be influenced by the factors that can affect all market activity on a Friday.

One consideration is that trading behavior on a Friday can differ from midweek, as some traders close positions before the weekend rather than carry the risk of news breaking while the market is shut. Watch how the specific stock actually trades rather than assuming a fixed pattern.

Before An Expiration-Day Trade

Whether you are trading weekly options on Friday, day trading weekly options, or trading weekly options in general, the same points of consideration apply. Make sure that you have a solid basis for entering all trades, and a well planned out exit strategy.

A Simple Premium Example

Suppose one standard, unadjusted stock option costs $1.20 per share and covers 100 shares. The premium is $120 before fees. Selling that contract for $0.70 returns $70, a $50 loss before fees; if it expires worthless, the $120 premium is lost. This is a hypothetical calculation, not a WOU trade result.
