Danelfin vs VectorVest: Best AI Stock Rating Tool for 2026

Danelfin is the cheaper and more focused option, starting at $22/month for an AI-generated 1-10 stock score, while VectorVest starts at $49.99/month for a broader VST rating system with built-in portfolio and screening tools. Pick Danelfin if you want a single machine-learning signal to layer onto your own research; pick VectorVest if you want a full standalone platform.

Both tools promise to condense a stock's outlook into one number, but they get there differently: Danelfin trains a machine-learning model on technical, fundamental, and sentiment data, while VectorVest uses a rules-based formula built around value, safety, and timing that predates the current wave of AI stock tools. This comparison covers exact pricing as of September 2026, what each score actually measures, and which one is worth paying for depending on your budget.

Which is more accurate, Danelfin or VectorVest?

Neither company publishes third-party audited accuracy numbers, so any comparison has to rely on each vendor's own reporting. Danelfin states that stocks scoring 10/10 on its AI Score have outperformed their benchmark by an average of 21.05 percent after 3 months since 2017, while stocks scoring 1/10 have underperformed by an average of 33.28 percent over the same window. VectorVest markets its VST system around decades of use but does not publish a comparable independent backtest figure on its public pricing pages.

Treat both numbers as vendor-reported, not independently verified. A 21.05 percent average outperformance is a meaningful claim if it holds, but it comes from the company selling the product, which is a real limitation worth remembering before sizing a position around either score alone.

Danelfin is the only one of the two that publishes a specific, dated backtest figure on its own site; VectorVest's accuracy claims are less specific and harder to verify independently.

Danelfin vs VectorVest pricing

Danelfin is cheaper at every comparable tier, and its free tier lets you see a limited set of AI Scores without paying anything, which VectorVest does not offer outright, it only offers deeply discounted trials. VectorVest's entry tier also delays quotes by 15 minutes, so if you need real-time prices you have to move up to the Enhanced or Premium tier to get them, which pushes the realistic starting cost closer to $99/month rather than $49.99.

On price alone, Danelfin undercuts VectorVest at every tier, and its free plan gives new users a genuine no-cost way to sample the AI Score before committing to Plus, Pro, or Elite.

What does each score actually measure?

Danelfin's AI Score

Danelfin's AI Score is a machine-learning model that ingests more than 10,000 technical, fundamental, and sentiment features per stock every day and outputs a single 1-10 score representing the modeled probability that the stock outperforms its benchmark over the following 3 months. It also produces a separate Risk score, so a stock can rank high on expected performance but also high on volatility.

VectorVest's VST rating

VectorVest's VST rating combines three sub-scores: Value (is the stock cheap or expensive relative to its own model of fair value), Safety (financial stability and volatility), and Timing (short-term price and volume trend). The three combine into buy, sell, or hold guidance rather than a single 1-10 number, and the platform is built around applying that rating to a managed watchlist or portfolio rather than screening one stock at a time.

Danelfin outputs a probability-style score meant to be layered onto stocks you already follow, while VectorVest's VST rating is built to drive buy, sell, and hold decisions directly inside its own portfolio tools.

How do the stock universes and screeners compare?

Danelfin covers US-listed stocks and ETFs and lets you filter its universe by AI Score, sector, market cap, and Risk score, then save the result as a watchlist that updates as scores change day to day. It is built to sit alongside a broker or charting app rather than replace one, so there is no order entry or portfolio tracking inside Danelfin itself.

VectorVest's entry tier covers roughly 9,500 US stocks, and the Enhanced and Premium tiers expand that to more than 16,000 stocks across the US, Canada, Australia, and Europe. That broader universe includes a custom watchlist and screener builder on Enhanced and above, plus a TradeNow brokerage integration on the top tiers that lets you route an order without leaving the platform.

VectorVest's larger, multi-country stock universe and built-in screener give it an edge for traders who want one tool to find ideas and manage a watchlist, while Danelfin's narrower US focus keeps it simpler for traders who already source ideas elsewhere.

Who should use Danelfin instead of VectorVest?

Danelfin fits traders who already have a research process, a broker, and a charting tool, and just want an extra machine-learning signal to sanity-check a watchlist. Its lower price and genuine free tier make it easy to test on a handful of stocks before paying for Plus, Pro, or Elite.

VectorVest fits traders who want one platform to replace several tools at once: screener, VST-based watchlist, and stop-loss guidance in the same subscription, at the cost of a higher monthly price and a 15-minute data delay unless you pay for Premium.

Danelfin suits traders layering one more signal onto an existing workflow, while VectorVest suits traders who want a single all-in-one platform and are willing to pay more for it.

The verdict

For most retail traders comparing the two on price and simplicity, Danelfin is the easier starting point: the free tier costs nothing, Plus starts around $22/month, and the single AI Score is quick to scan across a watchlist. VectorVest earns its higher price, starting at $49.99/month and reaching $149/month for real-time data, only if you actually want the full research and portfolio platform built around VST rather than a standalone score.

Neither company's backtest numbers are independently audited, so treat both AI Score and VST as one input alongside your own due diligence, not as an automatic buy or sell signal on their own. Budget also matters here: a trader paying $22/month for Danelfin Plus and a trader paying $149/month for VectorVest Premium are buying very different things, one extra signal versus one full platform, so match the tier to what you actually plan to use rather than defaulting to the cheapest or most expensive option.

Danelfin wins on price and simplicity starting at roughly $22/month, while VectorVest wins on breadth as a full portfolio platform starting at $49.99/month, and the right choice depends on whether you want one more signal or one complete system.
