One of the newest members of the U.S. Senate has taken congressional stock trading to new heights — or depths, depending on your perspective. Sen. Alan Armstrong (R-OK) recently disclosed more than 700 stock trades, and the mix of buys and sells tells a clear story: he's betting big on tech and cutting ties with his old industry.

From Oil to Silicon Valley

Armstrong, who was appointed to the Senate earlier this year to replace Markwayne Mullin (who left for a Cabinet position), just filed his first set of stock transactions dating back to March. And the biggest move? He sold between $5 million and $25 million worth of stock in Williams Companies (WMB) — the oil and gas company he used to run as CEO. He also unloaded between $250,000 and $500,000 in WMB stock options.

In total, the 703 trades were valued at an estimated $25 million or more, with at least $7.66 million in purchases and $17.37 million in sales, according to data from Quiver Quantitative. Most transactions fell in the $1,000 to $15,000 or $15,000 to $50,000 range, but the largest buys were concentrated in tech.

Here are Armstrong's biggest stock purchases, all from March:

• Apple Inc. (AAPL): Bought $250,000 to $500,000 in shares
• ASML Holding NV (ASML): Bought $50,000 to $100,000 in shares
• Berkshire Hathaway (BRK): Bought $50,000 to $100,000 in shares
• Alphabet Class C (GOOG): Bought $50,000 to $100,000 in shares
• NVIDIA Corporation (NVDA): Bought $50,000 to $100,000 in shares

Apple, Alphabet, and Nvidia are three of the so-called Magnificent Seven stocks, and Armstrong didn't stop there. He also bought shares of Amazon.com, Meta, Microsoft, and Tesla, though in smaller amounts. The message is pretty clear: the former oil CEO is now a tech bull.

Late Filings and a $200 Penalty

Here's where things get sticky. The STOCK Act requires members of Congress to report stock transactions within 45 days. Armstrong's trades date back to March — that's about four months ago. Watchdog group Unusual Whales flagged the disclosures, noting that Armstrong reported more than 700 stock trades "with nearly all filed well beyond the STOCK Act's 45-day reporting deadline."

The current penalty for violating the STOCK Act? A mere $200. Quiver Quantitative tweeted: "Senator Alan Armstrong just disclosed hundreds of stock trades made in late March, just days after he entered office. He JUST filed them – months past the deadline. This has got to be a record for the quickest STOCK ACT violation ever."

It's a reminder that while the rules are on the books, the enforcement is toothless. For a senator trading millions, a $200 fine is basically a rounding error. MarketDash will continue to track Armstrong's trading activity going forward.
