In March, Sandisk was a storage company most investors had never thought about. Stock Radar flagged it at $703.63. Eleven weeks later it closed at $1,761.43. Here is what members saw, and the three names on the list today.

Price change, before dividends. Sandisk, Micron and Astera Labs were all flagged by Stock Radar earlier this year.

$10,000 in Nvidia on the day ChatGPT launched was worth $135,508 by October 9, 2026. That is the trade everyone remembers. This year the money moved on. Nvidia sells the chips, but every chip needs memory, storage, power and links fast enough to connect thousands of them. Those became the bottlenecks, and the companies that sell them became the year's biggest winners.

  • Pick #3+54%

The prices fell. The businesses did not. Pick #1's AI cloud revenue grew 121% last quarter. Pick #3's data-centre revenue grew 66%. This week the market sold AI stocks hard and Nvidia alone lost about $270 billion in value, and Wall Street did not walk away: in the last 30 days analysts made 34 new calls on these three, 20 of them Buy. On October 2, Wells Fargo rated Pick #2 Overweight and raised its target from $85 to $100.

The investors who bought in the last 30 days, below, bought the same thing you are looking at: a lower price.

One of the three has been here before. Stock Radar flagged it in January, and it rose 76% in 16 weeks.
