Flow signature

🐜 mostly aggregated. This describes the shape of the order flow — how the accumulation was assembled — not its intent and not its likely outcome.

What happened

One-sided OTM-put accumulation as FUTU melted up into the SPAC/meme froth; the model flagged a large move, and it repriced violently over the following weeks.

The catalyst: Feb-2021 meme-froth peak.

The outcome: 60-day idiosyncratic −35% — a forward idiosyncratic move (beta-stripped vs SPY) over a mature 60-day window. The raw price shown on the chart reached −37%; the two differ because the outcome strips out the market’s beta.

The story behind it

Futu Holdings, a fast-growing Chinese online brokerage, rode the 2020–21 retail-trading and China-tech euphoria to about $204. IAS flagged the aggregated OTM-put buildup at the froth peak in February 2021.

Within weeks, Beijing's regulatory crackdown on tech and cross-border data — combined with a global rotation out of high-multiple growth — repriced the entire cohort. FUTU gave back most of the run. The accumulation signature showed up before the catalyst was obvious.

Read this honestly

Informed, not privileged

The tape showed accumulation. It cannot prove who traded, what they knew, or why.

Direction was not predicted

IAS called that a large move was coming — magnitude, never which way. Two cases in this library resolved UP; that is the proof.

Ranked by magnitude

The edge is the magnitude estimate — P(large move) — not raw IAS. A high IAS with a low magnitude estimate is unusual but not notable for movement.

Long volatility, not long puts

These names often spike the other way first. The historical behavior looks like long volatility, not a directional put position.
