How to read unusual options activity

FundSpec, 8 September 2026

Every options trade leaves a record: the contract, the size, the price and the time. Most of that record is routine. A small part of it is not, and that part is worth reading, because large sums committed to a specific strike and expiry say something about what a well funded participant expects to happen and when. This guide explains what FundSpec counts as unusual, what each figure on the flow screen means, and how experienced traders read the tape without over reading it.

What makes a print unusual

A print is a single executed trade. It becomes unusual when it stands out from the normal activity in its contract. The obvious signal is size: a trade of several thousand contracts in a name that usually trades a few hundred a day. A subtler one is size relative to open interest. If a contract has two hundred contracts outstanding and a single trade prints for two thousand, that trade is new positioning rather than someone closing an old position, and new positioning is what carries information.

Premium is the money behind the trade: contracts multiplied by the option price multiplied by the contract multiplier. A print of ten thousand cheap out of the money contracts may carry less premium than five hundred contracts of an at the money call in a large stock, and premium is the figure that tells you how much conviction was actually funded.

Execution matters too. A sweep is an order split across several exchanges so that it fills immediately at whatever prices are available, instead of resting at one venue and waiting for a better fill. Sweeping costs more. Someone who pays that cost wants the position now, which is why sweeps are read as urgent.

Bullish or bearish

Each print is classified by its likely direction. Calls bought at or above the ask are bullish, puts bought at or above the ask are bearish, and the aggressor side, whether the trade was initiated by a buyer or a seller, is inferred from where it executed relative to the bid and ask at the time. A call sold at the bid is not bullish; it is someone collecting premium, often against stock they already own.

This inference is good but not perfect. A trade that prints at the midpoint gives less information about who initiated it, and a print can be one leg of a multi leg strategy whose other legs executed elsewhere. FundSpec shows the classification it made and the execution details so that you can judge it.

Conviction tiers

FundSpec scores each print and sorts the most meaningful into tiers. Notable prints clear the basic thresholds. High Conviction prints combine large premium with new positioning and urgent execution. Whale prints are the largest commitments of the session, either by premium or by conviction score. The tiers exist so that the flow can be read quickly: the whales board on its own tells you where the most money and urgency showed up today.

Reading the day, not the print

A single print is an anecdote. The pulse view turns the day's prints into a picture. Net premium is bullish premium minus bearish premium across every tracked print, and its sign tells you which way the unusual money leaned. Tracked premium is the total behind those prints, which is not the market's total options volume; it is the unusual slice of it. The put to call ratio compares put premium with call premium, and the sweeps share tells you how much of the day's flow was executed urgently.

The top tickers list ranks names by the premium behind their prints and splits each bar into bullish and bearish, so a name with heavy flow on both sides reads differently from a name where all of it points one way.

Where flow misleads

Three habits keep options flow useful.

First, ask what the trade could be other than a directional bet. A large put purchase in a stock that has run up may be a holder buying protection rather than a bear taking a position. A large call purchase ahead of earnings may be a short seller hedging. Flow tells you that money moved; it does not tell you why.

Second, look at the expiry. A print in a contract expiring this week is a view about the next few days, often about a known event. A print six months out is a different kind of statement. Flow screeners let you separate the two.

Third, weigh the print against the stock. Ten million dollars of calls is a large commitment in a mid cap and a rounding error in the largest companies in the market. Premium relative to the stock's typical dollar volume is a better measure of how much the print matters than premium alone.

How FundSpec shows it

The Unusual Options screen has four views. Pulse sums the day and ranks the tickers. Flow lists every print with its premium, direction, sweep flag and conviction tier, and lets you filter by expiry, aggressor, strike, size, open interest and more, or save a screener of your own. Whales ranks the largest prints for today and the trailing week. Alerts notify subscribers when a print matches a saved screener. Free accounts see prints twenty minutes after they execute; FundSpec Unlimited removes the delay.

Read the pulse first, then the whales, then the flow for any name you care about. Then ask why, and hold the answer loosely.
