The
Control
Group

Part 1 of this investigation measured anomalous dollar volume in SPY and QQQ around a single event: the "GREAT TIME TO BUY" post on Truth Social, published April 7, 2025, forty-eight hours before the 90-day tariff pause that reversed Liberation Day.

The equity residuals were +262% on SPY and +234% on QQQ — dollar volume more than three and a half times the five-day baseline, on a day with no public catalyst, during an active market selloff.

A single data point, however large, is not an investigation. It is a question. The question is: does this reading represent something genuinely anomalous, or does the tool simply amplify any volatile trading day into an apparent signal?

To answer that, we need a control group. We need to run the same measurement against events where the outcome was known publicly, where news was real and market-moving, and where the volume response was legitimate. If those events produce comparable residuals, the tool is not measuring anomaly — it is measuring news. If those events produce materially lower residuals, April 7 stands alone.

Seven years of presidential trade policy provides that control group. We ran it.

The Methodology

Market Sentinel measures equity dollar volume within a defined pre- and post-announcement window, comparing it against the prior five trading days at the same time of day. The output is a residual percentage: how much more (or less) dollar volume moved in the event window than expected based on recent baseline behavior.

The tool makes no claim about intent. It does not identify who traded, what positions they held, or why. It measures one thing: whether markets behaved as if something was known before it was announced.

A high positive residual on a day of public news is expected and normal. A high positive residual on a day with no public catalyst is not.

The comparison set spans two distinct periods: the first Trump term (2018-2020), covering the G20 Buenos Aires truce, the G20 Osaka truce, the Phase 1 announcement, and the Phase 1 signing; and the second term through February 2026, covering Liberation Day, the April 7 post, the 90-day pause, the Geneva deal, the Kuala Lumpur deal, and the Supreme Court IEEPA ruling.

First Term: The Baseline for Legitimate Moves

The first Trump term produced four major trade-related market events with measurable volume signatures. Each represents a case where market-moving information became public through normal channels: a press conference, a White House announcement, a joint statement. No event in this group had known foreknowledge concerns at the time. They are, as far as can be determined, clean examples of legitimate news-driven volume.

The first-term range runs from +6.5% to +74.8%. G20 Osaka — a genuine surprise positive development announced at a summit that markets had been watching closely — produced the highest first-term reading at +74.8% on SPY. Phase 1 signing, a ceremony that had been scheduled and publicly anticipated for weeks, produced +25.4%.

This range establishes what legitimate major trade news looks like. Known events produce low residuals because they were priced in. Genuine surprises produce higher residuals because they weren't. The ceiling for a legitimate first-term event, against a baseline nearly seven years ago when daily dollar volume was considerably lower, was +74.8%.

Second Term: Where the Pattern Holds — And Where It Breaks

The second term events divide cleanly into two categories. Events where information was public before trading began — Liberation Day, the Geneva deal, the Kuala Lumpur deal — show elevated but interpretable residuals. Events with no public catalyst that preceded announcements by days show something else.

What the Pattern Shows

The control group establishes a ceiling. Seven years of major presidential trade events, including genuine market-moving surprises announced at international summits, produced equity volume residuals ranging from +6.5% to +74.8% in the first term, and from −1.9% to +125.2% in the second term. The second-term Liberation Day reading of +125.2% is the highest legitimate data point in the dataset — an after-hours announcement of the largest tariff action in a century, which had been telegraphed for weeks but whose specific scope was unknown.

April 7, 2025 produced +262.1% on SPY and +233.8% on QQQ. The only public event on that day was a Truth Social post stating it was a "GREAT TIME TO BUY." The market was in active freefall from Liberation Day. There was no scheduled announcement, no summit, no press conference, no Federal Register notice.

The November 10 data point is equally important, and receives less attention. The Kuala Lumpur deal was a genuine major policy action: it suspended the 125% China tariff through November 2026, cut the fentanyl tariff in half, and extended 178 product exclusions. In any normal week it would have been the biggest trade news of the year. On November 10, SPY produced a residual of +2.2% and QQQ produced −0.5%. The market had no advance signal. It absorbed the news in real time.

The contrast between April 7 and November 10 is the cleanest finding in the dataset. Two major policy reversals, comparable in scope, separated by seven months. One produced volume three and a half times normal. The other produced volume indistinguishable from noise.

The DJT Signal

There is one additional data point that has no direct first-term analog and deserves specific attention.

On April 7, 2025, while SPY and QQQ were trading $47.7 billion and $26.5 billion above their respective baselines, DJT — Trump Media and Technology Group, the president's own media company and one of the most politically correlated equities available — traded $6.2 million below its baseline.

The capital that moved on April 7 did not go into the obvious instrument. It went into the deepest, most liquid, most anonymous instruments available. DJT has no institutional investor base to speak of, high retail ownership, and direct symbolic association with the president. Someone moving on advance knowledge of a presidential reversal would have every reason to avoid it. The broad indexes offer scale, liquidity, and a degree of anonymity that a single correlated equity does not.

The DJT reading does not prove that the Apr 7 volume was anomalous. But it is consistent with the behavior you would expect from someone who understood the risk of being too obvious.

What This Layer Cannot Prove

Equity volume measures participation, not intent. A +262% residual means an unusual amount of money moved in a short window. It does not identify who moved it, what positions they held, or whether they had information that was not public. It establishes that markets behaved as if something was known. It does not establish that something was actually known, or by whom.

This matters for how the findings should be read. The equity layer is a signal, not a conclusion. Its value is in the comparison: when the same measurement applied to seven years of legitimate events produces a maximum of +125%, and a single day without a public catalyst produces +262%, the question being asked changes from "is this elevated" to "what explains the elevation."

There is a second layer of data. Options flow carries information that equity volume does not. The volume and direction of call and put premiums in a pre-announcement window reflects not just whether someone was positioned, but how they were positioned — whether the activity was directional buying or two-sided panic, and whether the instrument selection was consistent with someone who expected a specific outcome.

That layer is next. Part 3 will report what it shows.
