Today's Top Insider Moves That Matter

Today, the market gave us a tale of two mindsets. Growth-heavy sectors—especially semiconductors, infrastructure software, and e-commerce continued their tear, fueled by momentum and machine-led optimism. But the shadows crept in: communication services and biotech buckled under pressure, and consumer defensives barely moved. It’s a market sprinting forward with one foot still hovering over the brake.

Insiders, though? They’re not chasing the shiny stuff. They’re betting on the overlooked. We saw a biotech CEO go all in at penny-stock prices out of step with the market but possibly ahead of it. Meanwhile, the trucking and real estate industries, slow and steady on the charts, drew multi-million-dollar conviction buys. And the cluster action? Quiet, strategic, and deeply coordinated.

The message: Wall Street may be surfing AI froth, but the insiders are shopping for value, scale, and recovery. Today’s trades weren’t loud, but they were telling. Let’s get into it.

Biggest Insider Sales

🎮 Roblox Corp $RBLX ( ▼ 0.47% ) – CEO Sheds $137M as Stock Climbs

• Who’s Selling? David Baszucki (President, CEO, 10% Owner)

• What They Sold: 1,899,997 shares at $72.19

• Total Value: $137.2M

• Why It Matters: Baszucki dumped 57% of his stake in one move, more than just “routine rebalancing.” With Roblox trading near recent highs, this feels like tactical timing.

📱 Duolingo, Inc. $DUOL ( ▲ 1.02% ) – Co-Founder Offloads Nearly All Holdings

• Who’s Selling? Severin Hacker (CTO, Co-Founder, 10% Owner)

• What They Sold: 10,000 shares at $495.95

• Total Value: $5M

• Why It Matters: Hacker slashed 99% of his already-tiny position. While the amount is modest, the optics of a near-total exit by a founder should raise some eyebrows.

💰 Coinbase Global, Inc. $COIN ( ▼ 0.17% ) – Armstrong Trades Out $5M

• Who’s Selling? Brian Armstrong (Chairman, CEO, 10% Owner)

• What They Sold: 25,000 shares at $200.54

• Total Value: $5M

• Why It Matters: Armstrong’s 98% stake reduction feels more like a cash-out than a trim, especially with crypto markets heating up again.

🔡 Neurocrine Biosciences Inc $NBIX ( ▲ 2.26% ) – Director Cuts Stake in Half

• Who’s Selling? William Rastetter (Director)

• What They Sold: 30,000 shares at $110.20

• Total Value: $3.3M

• Why It Matters: A 44% reduction in holdings by a long-tenured director is rarely coincidental. Expect scrutiny if more follow.

🛡️ Osi Systems Inc $OSIS ( ▲ 0.35% ) – Executive Chairman Sells Into Strength

• Who’s Selling? Deepak Chopra (Executive Chairman)

• What They Sold: 25,000 shares at $221.45

• Total Value: $5.5M

• Why It Matters: A 7% trim from a large position isn't alarming alone, but this sale breaks a long quiet stretch of insider activity.

As sellers lighten up in tech and fintech, today's buyers are doubling down on infrastructure and biotech. Let’s see who’s putting fresh money to work.
