Zacks Investment Research highlights the similarities between Sandisk's recent 154% breakout and the epic 2003 surge of Taser, now called Axon Enterprise. Both companies saw their stocks soar after product innovations and market tailwinds, forming classic 'high tight flag' chart patterns that led to massive gains for investors who got in early.

Why it matters

The Taser and Sandisk stories demonstrate the power of embracing market momentum rather than searching for bargains. While Taser and Sandisk's meteoric rises may seem risky to some, the data shows that stocks exhibiting these 'high tight flag' patterns often continue to surge higher, providing life-changing returns for investors who recognize the patterns early.

The details

In 2003, Taser perfected its non-lethal TASER X26 weapon, which became the gold standard for law enforcement. This, combined with funding from the DoD, led to over 4,000 agencies adopting Taser's technology by the end of the year. Sandisk is now seeing a similar surge in demand for its NAND flash memory products amid the AI data center building boom, leading to triple-digit earnings growth projections.

  • In late 2002, Taser stock began a meteoric rise from $0.40 to $33.45 by the end of 2004.
  • In January 2026, Sandisk shares broke out of a high tight flag pattern, gaining 154% in just 4 weeks.
  • Since then, Sandisk has consolidated in a 25% range, potentially forming another high tight flag.
