10 most popular stocks in February 2026 on Robinhood UK
Plug Power, MARA and NVIDIA leapt back onto the list in March, as Robinhood UK investors kicked out some big names like Amazon and Microsoft, and brought in a tech newcomer.
‘AI scaffolding’ firms out in force in March
Absolutes might make the world easier to understand but the market is often a more relative place. Take the tech sector - the main narrative shaking markets early in 2026 was the hyperscalers’ hefty AI spending plans. But, with the conflict in Iran providing an even bigger epicentre for market worries, suddenly the highly profitable tech names were back in vogue because of their balance sheets’ apparent relative safety.
Robinhood UK investors are still backing the tech scene, blending the sector’s household names with companies sitting slightly outside the AI spotlight. Among the former, NVIDIA was a March favourite for Robinhood investors after CEO Jensen Huang announced a $1tn order pipeline for the firm’s Blackwell and Vera Rubin products. AI memory demand drove appetite for Micron and SanDisk, with both getting a helping hand from NVIDIA’s pipeline announcement.

Plug Power shot to the top of the list after the company beat Q4 revenue expectations, posted a positive gross margin for the first time and appointed new leadership who came in with punchy earnings targets. The hydrogen fuel cell firm has also pivoted into providing power solutions for data centres, attaching the stock to the AI buildout narrative.
MARA and IREN are still attracting attention thanks to having one foot in AI infrastructure and the other in the crypto world. A mid-month rebound in Bitcoin lifted both stocks, along with the BTC-hungry Strategy. Michael Saylor’s firm has snapped up around 45,000 BTC over the past month or so, marking the company’s largest 30-day buying spree since April 2025.

How to pick your first stock: our five-step guide
In March, Oracle showed just how much its cloud business is growing from AI demand. Cloud revenue infrastructure was up around 40% on last year, with contracted future revenue of about $550bn demonstrating customers are signing multi-year deals rather than just testing AI projects.
It’s been a juddery move south for Tesla stock in 2026 and March continued the pattern. Without a major company announcement to look to, sentiment likely soured further on the back of interest rate hike fears and uneven demand for electric vehicles. Robinhood UK investors were still interested in the stock, as the world starts to wonder what the future looks like for Elon Musk’s stable of companies.
Results from Ondas made for a volatile end to March for the drone firm. A 629% hike in revenues compared with last year boosted the stock but a net loss of over $100m for the quarter weighed on the share price soon after. The episode demonstrated just how quickly the firm is growing but also how much it’s still losing - that’s hard for the market to overlook, especially as it has been so squeamish over how capital intensive the AI evolution has become too.
