InvestingPro members who subscribed to a monthly AI-driven selection of stocks experienced a notably strong January, with multiple technology names posting double-digit rallies and one standout stock producing an outsized jump this month.
Short-term winners and standout performances
Several selections on the list generated rapid gains during January, including:
- Amkor Technology Inc (NASDAQ: AMKR): +26.65% in January alone
- Onto Innovation Inc (NYSE: ONTO): +35.01% in January alone
- Teradyne Inc (NASDAQ: TER): +30.13% in January alone
- Stride Inc (NYSE: LRN): +29.43% in January alone
Beyond these four names, the list produced more than fifteen additional stocks that each rose by at least 25% over the month.
SanDisk: the portfolio's dominant mover
Central to the outperformance was a technology stock that the AI models identified as a high-conviction pick in November. That stock, SanDisk Corporation (NASDAQ: SNDK), rallied an extraordinary +174.2% month-to-date. Since being added to the model's selections three months earlier, the position has produced a compounded gain of +227.38% for members tracking that recommendation.
Subscribers to the premium list were alerted to SanDisk's strength repeatedly during the rally: notices were issued when the stock was up 48%, again at 71%, and a third time after a 112% increase. Those communications preceded the most recent surge.
Portfolio-level results versus the benchmark
The actively managed composition of technology picks rose +13.30% month-to-date, a substantial outperformance relative to the S&P 500's +1.80% gain for the same period. Over a longer window, the strategy has shown even greater divergence: since its official launch in November 2023, the actively managed tech selection is up +182.53%, reflecting an outperformance of +118.04 percentage points versus the S&P 500 over the same timeframe.
These figures are reported as real-world results recorded since the models' official launch.
Why SanDisk was chosen by the model
When the AI first added SanDisk to the list in November, it characterized the company as an "AI-fueled memory market superstar". The published rationale at that time highlighted the following points:
- Extremely strong recent market performance, with a 527% price return over six months and 468% year-to-date, bringing the stock near its 52-week high.
- Positioning to benefit from surging AI-driven demand for NAND memory, with projections cited for the AI NAND chip market through 2029 and SanDisk positioned as a primary beneficiary of that trend.
- Revenue growth of 10.4% accompanied by EBITDA growth of 362%, cited as evidence of robust operational execution in an expanding market.
- Multiple analyst upgrades and target increases, including Mizuho doubling its price target to $112, Morgan Stanley raising its target to $96 and naming SanDisk a Top Pick, and Bernstein initiating coverage with an Outperform rating.
- Reports that the company is seeking 10% price increases while securing large hyperscaler orders.
The AI's rationale for every stock is published when the model adds or removes names from the portfolio.
Developments since the November recommendation
Three months after the initial inclusion, SanDisk reported revenue that rose 64%, a leap attributed to strong uptake among AI infrastructure builders, semi-custom customers, and technology companies deploying AI at scale. Despite that top-line acceleration and the continuing momentum in the shares, valuation models used by the platform's fair-value framework indicate a potential downside of -32.45% from current price levels.
The divergence between continued operational strength and a stretched valuation poses a tactical decision for investors: whether to ride the momentum or rotate to other opportunities identified by the AI. The model updates its list at the start of each month, and subscribers can review whether SanDisk is retained or removed in the latest cycle.
How the AI-driven selection process operates
At the beginning of each month the AI refreshes each strategy and can include up to 20 stock picks. The selections are derived from a synthesis of more than 150 established financial models embedded in the machine learning framework, trained on over 15 years of global financial data.
As market conditions and company fundamentals change, the model may add new names, retain current holdings, or remove companies that no longer meet its medium-term growth criteria. For performance tracking, the strategy applies equal weighting across all selected stocks, which serves as a consistent benchmark though subscribers are not required to follow that exact allocation.
The designers emphasize that stock picking remains a probabilistic exercise. The AI's process aims not only to find winners but also to recognize when positions no longer merit inclusion.
