There were no S&P 500 earnings reactions on Monday, but we want to tell you about a stock outside of the S&P 500 that has our attention.
Some companies are trying to build the future.
Others are already doing it.
Amprius Technologies $AMPX falls firmly into the second category.
The company is a next-generation battery manufacturer focused on high-energy-density lithium-ion batteries built with silicon anodes.
In plain English, their technology allows batteries to store more energy while weighing less, a critical advantage for industries where performance per pound matters most.
That includes electric aviation, drones, defense systems, satellites, and high-performance electric vehicles.
As these industries scale, the need for lighter and more powerful batteries grows exponentially.
Amprius has already positioned itself as one of the leaders in that race, and investors are starting to notice.
This is a $2.3B battery company with one of the hottest charts in the entire market right now.
Since going public in 2022, AMPX has been building what now looks like a massive multi-year base.
The stock initially collapsed after its IPO, eventually cratering roughly 97% from its early highs. But that capitulation phase ultimately marked the bottom.
In late 2024, buyers stepped in aggressively.
Since that low, AMPX has rallied nearly 3,000% and closed last week at brand-new all-time highs. And so far this week, buyers are continuing to follow through to the upside.
From a technical perspective, this is exactly what a major base breakout looks like.
After years of accumulation, the stock is now resolving higher as demand overwhelms supply. These kinds of structures often mark the beginning of long-term leadership trends.
But the most compelling part of this story isn’t just the chart.
It’s the earnings sentiment fueling the move.
The shift in sentiment began right around the time the stock bottomed in late 2024.
In November of that year, AMPX delivered a +33% earnings reaction, the largest in the company’s history. That move marked a clear turning point in the market's response to the company’s results.
Then came confirmation.
In March 2025, the stock followed through with an even stronger +34.6% earnings reaction.
Since that inflection point, the market has remained firmly in the stock’s corner. AMPX has posted consistently positive earnings reactions, with only one negative response, and even that was only -0.80%.
In other words, the market keeps rewarding the company’s results.
And the reason is simple.
The growth is extraordinary.
Quarter after quarter, Amprius is delivering triple-digit revenue growth. In the most recent report, revenue surged 137% year-over-year, following prior quarters that saw growth rates of 172%, 350%, and even 382%.
Those kinds of numbers are rare.
Right now, the company is still in the early stages of scaling its business, which is why profitability hasn’t yet kept pace with the explosive top-line expansion.
But if the current trajectory continues, that growth will eventually translate into the bottom line.
And the market appears to be positioning for exactly that outcome.
When you combine a massive multi-year base breakout, relentless revenue acceleration, and consistently positive earnings sentiment, you get the kind of setup that can power some of the market’s biggest winners.
AMPX is quickly becoming one of those stories.
And if the current trends continue, this breakout could still be in its very early innings.
