While Nokia and BlackBerry stocks finished the regular session over 6% higher each, Micron stock surged over 19%.

NOK Benefits From AI Networking Demand

Nokia shares surged to over a twenty-seven-year high of $16.63 on Tuesday, after investors reassessed the telecom equipment maker’s role in high-speed AI data infrastructure.

The company has expanded its AI and cloud networking business while strengthening its optical networking capabilities through its acquisition of Infinera last year.

Strong Q1 results, rising AI and cloud revenue, new partnerships with AMD and Super Micro last week, and FCC approval for its broadband products have boosted investor confidence.

On Stocktwits, retail sentiment around the stock remained in ‘bullish’ territory.

MU Dazzles Amid AI Memory Boom

Micron stock rocketed to a record high of $916.76 as demand for advanced AI memory chips remained elevated. Investors focused on the company’s HBM3E and HBM4 memory products, which are widely used in AI accelerators and high-performance computing systems.

On Tuesday, Micron received a major vote of confidence from UBS, which increased its price target on MU to $1,625 from $535, citing stronger long-term earnings potential tied to AI demand and improving conditions across the memory chip industry.

The new price target implies a 81% upside potential to the stock’s closing price on Tuesday. UBS projected that structural shifts tied to AI adoption may drive significantly stronger earnings and free cash flow for Micron through 2029.

Also, Micron surpassed $1 trillion in market value on Tuesday, making it one of the breakout winners of the AI boom. Retail sentiment around the stock jumped to ‘extremely bullish’ from ‘neutral’ territory the previous day.

BB Reinvents Its Market Position

BlackBerry shares also climbed to a fresh one-year high of $8.6 as the company continued to strengthen its position in automotive software and cybersecurity. Its QNX operating system remains embedded in millions of connected vehicles and industrial systems worldwide.

Investors additionally responded to BlackBerry’s progress in restructuring operations and securing government-related cybersecurity certifications for its AtHoc communications platform last week. The company’s growing software and licensing revenue streams have helped improve investor confidence.

Retail sentiment around the stock remained in ‘extremely bullish’ territory.

So far this year, MU stock has surged over 213%, while NOK and BB stocks have gained 154% and 122%, respectively.
