Former senator and current Department of Homeland Security Secretary Markwayne Mullin was known for his stock trading during his time in the Senate. While he no longer has to disclose his stock trades as often, the senator may be wishing his former disclosures about Dell Technologies (NYSE:DELL) were kept secret.
Mullin Sells Dell Stock Too Soon
President Donald Trump told investors to "go out and buy a Dell" earlier this month. The president praised Dell founder Michael Dell and publicly supported the company at a White House speech.
The speech came as Trump had already bought shares of Dell in a personal investment account and ahead of the technology company winning a Pentagon contract.
Dell stock is up around 80% since Trump publicly recommended the company.
Some investors may have heeded Trump’s call to buy Dell products or shares, but Mullin sold out of Dell entirely across December 2025 and February 2026 — missing the substantial gains that followed.
Here are Mullin's trades in Dell over the last year, as tracked on the Benzinga Government Trades page.
- Feb. 4, 2026: Sold $15,000 to $50,000, joint account
- Dec. 18, 2025: Sold $15,000 to $50,000, spouse account
- Dec. 18, 2025: Sold $15,000 to $50,000, self account
- Feb. 3, 2025: Bought $1,00 to $15,000, joint account
- Jan. 2, 2025: Bought $15,000 to $50,000, self account
- Jan. 2, 2025: Bought $15,000 to $50,000, spouse account
The three latest transactions were each marked as full, meaning the entire stock position was sold.
Based on the high price of Dell stock on the date of purchase and the date of sale, Mullin made a profit in his Dell stock transactions, as follows:
- Feb. 4, 2026: +21.8%, profit of $3,270 to $10,900
- Dec. 18, 2025 (spouse): +9.6%, profit of $1,440 to $4,800
- Dec. 18, 2025 (self): +9.6%, profit of $1,440 to $4,800
While Mullin likely made a profit on all three trades based on the selling price and dates of the transactions, he could have made significantly more.
Mullin's Dell Value Without Sale
Dell stock hit a high of $123.04 on Feb 4, 2026 and a high of $128.69 on Dec. 18, 2025. Compare that to today's price of $405.20. If Mullin still held the stock, here's how much the stock would be up and the potential gains.
- Stock bought on Feb. 3, 2025: +301.1%, profit of $45,165 to $150,550
- Stock bought on Jan. 2, 2025 (self): +245.0%, profit of $36,750 to $122,500
- Stock bought on Jan. 2, 2025 (spouse): +245.0%, profit of $36,750 to $122,500
In total, Mullin would be up $118,665, to $395,550, across the three Dell positions, compared to his previous annual Senate salary of $174,000 and his DHS Director annual salary of $246,000.
Instead, Mullin likely made somewhere between $6,150 to $20,500 for selling Dell stock when he did.
