The President Is Exempt From the Stock Ban. He Is Not Exempt From Insider Trading Law.

The House passed the Stop Insider Trading Act in July, and the headline was the exemption. The bill bars members of Congress from buying individual stocks, passed 232 to 198 and does not apply to the president or vice president. It reads like Congress deciding the president is above the law. He isn’t. The exemption is narrow, and a statute already on the books says he cannot trade on what he learns in office. The harder question is why nobody can enforce it.

Section 208 Does Not Reach the President

The usual citation for presidential conflicts is 18 U.S.C. Section 208, which makes it a crime for federal officials to act on matters affecting their own finances. The president is not covered. Section 202(c) defines the president, vice president, members of Congress and federal judges out of it. The logic is structural: a president cannot recuse himself from the presidency. Most commentary stops there.

The STOCK Act Names Him Expressly

The STOCK Act of 2012 answers a different question. Insider trading liability depends on breaching a duty of trust and confidence, and before 2012 it was unclear whether public officials owed one. The STOCK Act settled it by statute: members of Congress and executive branch employees owe that duty to the government and the public with respect to nonpublic information gained in office. Its definition of “executive branch employee” includes the president by name.

Under the misappropriation theory the Supreme Court adopted in United States v. O’Hagan, trading on confidential information in breach of such a duty is securities fraud. So Section 208 says the president need not step aside from decisions affecting his money. The STOCK Act says he may not trade on what those decisions reveal.

The House bill doesn’t change that. It adds a bright-line purchase ban for Congress and leaves the president under the 2012 duty, a fraud standard requiring proof that has never been applied to anyone in his office.

The Volume Problem

The facts are testing that standard. Bloomberg found the president and his team made nearly 28,700 trades between his January 2025 inauguration and the end of June 2026, compared with 22,200 by all members of Congress combined. His latest disclosure added 1,152 more in July alone. Bloomberg Law reported that many involved large companies doing business with the federal government, often in bursts tied to market events he created.

Volume proves nothing by itself. A separate Bloomberg review found patterns consistent with overlapping, often index-based strategies, much of it likely automated. The White House says independent managers run the portfolio and the president and his family have no ability to influence it.

That is the defense any case would have to overcome. Rule 10b5-1 protects trades made under a preexisting arrangement that gives the insider no later influence. If the managers are truly walled off, the trades are not made on the basis of anything the president knows. If information reaches anyone touching the portfolio, the defense fails. Everything turns on facts no outsider can see.

Enforcement Runs Into the Branch He Controls

Civil enforcement belongs to the SEC and criminal enforcement to the Justice Department. Both sit in the executive branch, and the Justice Department reports to the person who would be investigated. The Office of Legal Counsel has also concluded that a sitting president cannot be indicted.

Then there is Trump v. United States. Trading a personal portfolio is not an official act, so immunity would not cover it. But the Court also held that evidence of official acts generally cannot be used to prove liability for unofficial conduct. An insider trading case must prove where the information came from: meetings, briefings and deliberations that are official conduct. A prosecutor could have a duty and a trade but no admissible way to connect them.

The Clock Keeps Running

None of this expires with the term. The statute of limitations for criminal securities fraud is six years, and the SEC can seek disgorgement for up to ten years for intentional violations. Trades late in a term ending January 2029 could remain exposed well into the next decade, under a different Justice Department.

The House exemption doesn’t put the president above the law. It leaves him under a duty Congress wrote 14 years ago, with his office in its definitions, and no mechanism that works while he controls the agencies that would enforce it. That gap was always there. Twenty-eight thousand trades have made it visible.
