Just spotted something wild in the charts that reminds me of one of Wall Street's most legendary runs.

Back in the early 2000s, Taser - the stun gun manufacturer, now called Axon Enterprise - absolutely shocked the market. We're talking an 8,262% return from late 2002 to late 2004. The stock went from $0.40 to $33.45. That's the kind of move that changes lives.

What made it happen? A few things aligned perfectly. First, they actually solved a real problem. In 2003, Taser released the X26 - a non-lethal weapon that was lighter and less bulky than their earlier models. If you're wondering what's a stun gun and why it matters, basically it gave law enforcement a middle ground. Before this, cops had a brutal choice: use lethal force or nothing at all. The X26 changed that game. Within a year, over 4,000 law enforcement agencies adopted it.

Then came the timing. Post-9/11, the Department of Defense started funding them to equip military and pilots. Perfect storm of innovation plus tailwinds.

Here's where it gets interesting though. Taser's real move came after it had already surged 1,000%. Most people missed the initial run because the stock was illiquid and unknown. But smart money kept riding it.

William O'Neil, one of the greatest growth investors ever, made a fortune off patterns like this. He called them high-tight flags. The setup is simple: a stock rallies 100% or more in 4-8 weeks, then consolidates with a shallow 25% pullback over 3-5 weeks, then breaks out higher. Taser actually did this twice in a row.

Now fast forward to 2026. I'm seeing the exact same pattern with Sandisk. The stock broke out of a textbook high-tight flag in January and ripped 154% in just four weeks. Since then it's been consolidating in a tight range, and it looks like another flag is forming.

Why does this matter? Because Sandisk is actually growing like crazy. They make NAND flash memory for data centers and AI workloads. The demand is insane right now - supply can't keep up. Consensus estimates show triple-digit earnings growth through 2027.

The parallel to Taser is uncanny. You've got explosive fundamental growth, a real catalyst (AI infrastructure buildout), and a technical pattern that historically precedes monster moves.

Jesse Livermore said it best: there's nothing new on Wall Street. What happened with Taser in 2003 is happening again. The stocks that make life-changing money usually aren't the bargains everyone's hunting for - they're the ones showing strength.

Sandisk might be following that same playbook. Worth watching closely if you're into this kind of technical setup.
