AltIndex Top Picks Deliver 47.5% in Six Months - Crushing the S&P 500

September 28, 2:55 pm

Every day, we analyze over 2000 stocks and provide with an AI score that summarizes the stocks potential to put the market. Six months ago, we flagged a select group of stocks with exceptionally high AI scores. Today, the results are in: those stocks have delivered an average return of 47.5%, far outpacing both the broader market and their low-scoring peers.

For comparison, the S&P 500 has risen 19% in the same period. Companies with an AI score below 20 posted only a 4% average gain. The difference could hardly be clearer: stocks with a high AI score dramatically outperform.

Six Months of Outperformance

Our model identified just 18 companies with scores of 70 or more six months ago. Fourteen of those names have moved higher since then, with several posting eye-catching gains.

• Nebius (NBIS): +383%, soaring from $22.31 to $107.70.
• Astera Labs (alab): +225%, from $60.78 to $197.78.
• Quanta Services (pwr): +59.5%, from $254.12 to $405.44.
• KLA Corporation (klac): +58.7%, from $670.54 to $1,064.29.
• Cyberark Software (cybr): +43.1%, from $335.74 to $480.45.

These are not speculative microcaps or short-term meme stocks. They are established businesses that AltIndex’s algorithms identified as likely outperformers based on robust signals across fundamentals, technicals, and alternative data.

Here’s the complete breakdown of all 18 companies that carried AI scores of 70 or more six months ago, along with their returns:

	Company	Return (6m)	AI Score (6m ago)
	Nebius NBIS	382.74%	70
	Astera Labs ALAB	225.40%	71
	Quanta Services PWR	59.55%	74
	KLA Corporation KLAC	58.72%	72
	Cyberark Software CYBR	43.10%	72
	Sea Limited SE	41.26%	72
	Alamos Gold AGI	28.84%	77
	Intuitive Machines LUNR	24.91%	74
	Banc of California BANC	19.40%	74
	Talos Energy TALO	7.68%	72
	Stock Yards Bank SYBT	4.95%	70
	Duolingo DUOL	3.62%	71
	Archrock AROC	2.00%	70
	B1 Bank BFST	0.04%	70
	Samsara IOT	-2.34%	70
	Diamondback Energy FANG	-4.56%	72
	Nextdecade NEXT	-12.55%	72
	Cava CAVA	-27.07%	70

While the results are impressive, it’s important to remember that not every high AI score translated into gains. Four of the 18 companies saw their stock prices decline, underscoring that AI-driven stock prediction is not a perfect science. CAVA should probably have been flagged as a stock who already seen massive gains, with some potential risk to go even higher.

Investors should also note that past performance does not guarantee future results, and market conditions can shift quickly.

How the AI Score Works

Every day, AltIndex processes signals from thousands of publicly traded companies. Traditional metrics such as revenue growth, EBITDA, and margins are combined with technical indicators like moving averages and RSI. But what sets us apart is its use of alternative data, including:

• Workforce dynamics: job postings, LinkedIn employee growth, employee sentiment, etc.
• Digital footprint: website traffic, app downloads, search interest ,etc.
• Market sentiment: social media mentions, Glassdoor reviews, online chatter, etc.

This 360° view allows the AI score to highlight companies that are gaining traction across multiple dimensions, not just their stock chart. A score above 70 typically signals strong momentum and growth potential, while lower scores often highlight underperformers.

Our AI Scores vs the Market

The last six months provide a compelling natural experiment:

• High AI scores (≥70): +47.5% average return.
• Low AI scores (<20): +4% return.
• S&P 500: +19%.

Investors who followed AltIndex’s top-rated stocks significantly outperformed not only the benchmark index but also the vast majority of peers.

What This Means for Investors

The story here is not just about one-off winners like Nebius or Astera Labs. The broader point is that systematic AI-driven signals consistently beat the market. Out of 18 high-scoring companies, nearly 80% delivered positive returns - and many outperformed by wide margins.

This highlights the practical value of AltIndex’s AI stock picks page, where the highest and lowest scoring companies are updated daily. For investors, these scores offer an evidence-based way to focus on stocks with the strongest forward-looking potential while avoiding those at risk of underperformance.

Looking Ahead

The results of the past six months are striking, but they are only the beginning. Market conditions will evolve, and new leaders will emerge. AltIndex’s AI-driven models are designed to adapt in real time, scanning for the next set of companies that meet the criteria for high scores.

Just as Nebius, Astera Labs, and Quanta Services stood out six months ago, the next wave of top performers is already being identified. For investors, the lesson is clear: high AI scores point to stocks with a strong likelihood of beating the market.
