About Sirius Investors
What Is Sirius Investors
Sirius Investors (siriusinvestors.com) is a web platform that puts quantitative models, fundamental analysis and AI research into one place. It covers 75,000+ stocks, ETFs and cryptocurrencies across more than 50 global exchanges, and pulls in more than 15,000 SEC filings for analysis. Rather than another stock research platform that spits out a list, it aims to explain why an investment might be attractive.
The developer built it for individual investors, not funds. The pitch is straightforward: professional research platforms often cost hundreds of dollars a month, well beyond what most retail investors will pay. Sirius Investors sets out to deliver comparable depth at a much lower price, with the company claiming savings of up to 95% against providers such as Bloomberg and FactSet. That claim comes from the vendor, so treat it as a target rather than a measured result.
The limits matter too. It handles stocks, ETFs and crypto, so it is not built for options, futures or forex. The analysis runs on models it selects rather than ones you train, and nothing about the platform amounts to investment advice. You still make the call.

Key features
Investment Score
The Investment Score is a fundamental analysis tool and rating rolled into one. It rates a security from 0 to 100 using three factors: Value, Quality and Momentum. Value looks at whether a stock is cheap against its fundamentals; Quality looks at the strength of the business; Momentum looks at price trend. Each score comes with a 12-month history, so you can see whether a company has been improving or sliding, and a benchmark against the S&P 500. It is the feature the product is built around, and the one that answers the question of whether a stock is worth a closer look.
AI Stock Screener
The AI Stock Screener filters through more than 10,000 stocks and ETFs using 30-plus criteria, covering fundamentals, technicals and AI-driven suggestions. You can set a value threshold, a momentum cutoff, or a combination, then sort the results. The point is speed: instead of building a watchlist by hand, you narrow thousands of securities down to a shortlist that matches what you are after, and the platform flags names it thinks fit.
Automated portfolio building
Acting as an AI portfolio manager, the platform asks about your goals and risk tolerance, then proposes an allocation. If you already hold positions, you can import them from a broker or a CSV file and get an instant read on how they fit together. Risk assessment and rebalancing suggestions come with the analysis, and the company says the process runs in under three seconds. For anyone who has spent an evening in a spreadsheet trying to work out overlap between funds, that is the appeal.
AI Search and multi-model analysis
AI Search answers questions in plain language and returns market data and news alongside the reply. A multi-model mode puts the same question to OpenAI, Claude, Gemini and DeepSeek models, so you can compare their answers rather than trusting one. On a volatile day, hearing four takes on why a stock moved is more useful than a single confident-sounding line.
Technical and fundamental analysis
The platform covers both sides of the traditional divide. Technical Analysis brings price action, support and resistance levels and momentum indicators. Fundamental Analysis covers financial statements, ratios and competitive positioning. Having them in one view saves the tab-switching that comes with running a charting site and a filings site at the same time.
Market news and sentiment
News sentiment scoring and event impact prediction try to connect headlines to your holdings. The platform also tracks trending securities, sector rotation and social sentiment from communities such as Reddit. If you want to know what retail investors are talking about before it shows up in price, this is where you look, with the caveat that social sentiment is noisy by nature.
Global market coverage
Coverage runs across stocks, ETFs and cryptocurrencies on 50-plus exchanges, with multi-market and cross-asset analysis. For investors who hold international names, that means one account rather than a patchwork of regional tools, and a consistent scoring method applied to each.
