AltIndex Members Are Outperforming the S&P

December 5, 7:33 am

The market has been strong this year with the S&P 500 up 17%. Yet our analysis reveals something more impressive. AltIndex members who rely on alternative data insights are outperforming the market and identifying opportunities earlier.

On AltIndex, members can add stocks to a personal portfolio to track company performance, monitor alternative data signals, and receive real time alerts on the businesses they follow. After reviewing all portfolios with at least three positions, we can see that the average AltIndex member is up 23% year to date. This means the typical member is outperforming the S&P by six full percentage points.
The majority of users on the platform have also seen gains, with 82% posting positive returns so far this year. These results highlight how combining traditional investing with alternative data and timely stock alerts can improve decision making and help users recognize strong opportunities earlier.

Why Members Are Beating the Market

One of the biggest advantages investors gain on AltIndex is the ability to act on insights that go beyond traditional financial statements. Members have access to alternative data signals that show how a company is developing in real time. These include hiring momentum, app downloads, sentiment trends, social media growth, customer interest, employee outlook, and other indicators that often move ahead of stock prices.

Members also receive stock alerts and buy and sell signals powered by these datasets. These features provide a clearer picture of which companies are gaining momentum and which may be losing steam.

There are several real examples of how this approach has helped investors:

Robinhood

Last November, AltIndex issued a buy signal on Robinhood (HOOD) based on rising web traffic, improving customer engagement, stronger hiring metrics, and a growing presence in trading communities. Since that alert, HOOD is up 270%.

Rocket Lab

In August last year, alternative data showed Rocket Lab (RKLB) gaining popularity across multiple stock subreddits and online communities. AltIndex highlighted this trend in a Reddit Stock alert to our members. Since then, RKLB is up over 100%.

These are the types of early signals that give members an informational edge. When combined with broader market analysis, they help investors recognize compelling opportunities sooner and avoid relying only on backward looking indicators.

What Members Are Investing In

A review of the most commonly held stocks shows a strong concentration in companies shaping the future of AI, cloud, and digital platforms. These sectors have been major drivers of market performance in 2025. Here are the ten most popular stocks among members and their year to date returns:

Company		YTD Return
	Tesla TSLA	19.90%
	NVIDIA NVDA	34.83%
	Microsoft MSFT	14.79%
	Meta META	12.22%
	Apple AAPL	14.66%

	Google GOOGL	67.49%
	AMD AMD	81.06%

Several of these companies, particularly those tied to AI, have delivered standout returns for investors this year. Their strong presence in member portfolios has played a major role in lifting the average performance across the platform.
