What Does "Bullish" or "Bearish" Mean on a Card?
The single most common question we get. Short answer: it's always a read on the stock — never on which way the option's own price will move.
A worked example
Say you see a card for a put option tagged Bullish. That looks like a contradiction if you read it as "the option is bullish" — puts go up in value when a stock falls, so how can a put be bullish?
It isn't a contradiction, because the tag was never about the put's own price. It's about what the trade implies for the stock. There are two very different ways to trade that same put, and they mean opposite things:
| What happened | What it implies for the stock |
|---|---|
| The put was bought (aggressive buyer, paying up) | Bearish — paying for downside exposure or protection |
| The put was sold / written (aggressive seller) | Bullish — collecting premium at that strike rather than paying for downside |
Same contract, same strike — opposite stock read, depending entirely on which side was aggressive. That's why the card always shows the aggressor (bought at ask vs. sold at bid) alongside the Bullish/Bearish tag — the tag is derived from the aggressor side plus whether it's a call or a put, not from the option type alone.
| Aggressor | Call (CE) | Put (PE) |
|---|---|---|
| Bought (at ask) | Bullish | Bearish |
| Sold / written (at bid) | Bearish | Bullish |
The accumulation structure labels
When a strike builds up over several prints in one window rather than a single sweep, we tag it with a structure label — this describes what's being built, not just the direction:
| Label | What's happening | Read |
|---|---|---|
| Breakout Accumulation | Calls being bought | Reads bullish to us — calls paid up for at this strike |
| Breakdown Accumulation | Puts being bought | Reads bearish to us — puts paid up for at this strike |
| CE OI Build | Calls being written/sold | Reads bearish to us — calls parked above the stock |
| PE OI Build | Puts being written/sold | Reads bullish to us — puts parked below the stock |
The Bullish/Bearish word you see in front of the label (e.g. "Bullish PE OI Build") is just that same read spelled out, so you don't have to memorize the mapping above — but now you know where it comes from.
Every read on this page is ours — derived from which side crossed the spread, never published by the exchange — and it describes what traded, not what the stock does next.
