How to Actually Evaluate an AI Quant Tool
When a company tries to sell you an AI stock picking subscription, they will blind you with charts, "Proprietary K-Scores," and backtested Sharpe ratios.
You must act as an auditor. Here is the exact checklist we use at AI & Stocks to evaluate platforms like Kavout, TrendSpider, and Danelfin.
The Auditor's Checklist
1. Is the data "Out-of-Sample"?
If a company claims their AI is trained on data from 2010 to 2022, and their advertised backtest also covers 2010 to 2022, the results are worthless. They have just proven the AI is good at memorizing the past. You must demand out-of-sample testing—performance on data the AI was never allowed to see during its training phase. (Read more on The Overfitting Trap).
2. Do they account for Survivorship Bias?
If the AI tests its historical performance on the current S&P 500, it is cheating. The current S&P 500 only contains companies that survived and thrived. It ignores companies like Enron or Lehman Brothers that went bankrupt. The AI must backtest using the historical index constituents of that exact day.
3. What is the Trade Frequency?
If the AI requires you to execute 15 trades a day, you are not investing; you are a high-frequency day trader without the infrastructure to do it profitably. You will lose all your alpha to slippage and fees. Look for systems that trade weekly or monthly.
4. Does it beat a risk-adjusted benchmark?
If an AI tool returns 30% in a year, but the Nasdaq (QQQ) returned 40%, the AI is a failure. You paid a subscription fee to underperform a free ETF.
Furthermore, if the AI returned 40% but suffered a 50% drawdown to get there, it took on massive, uncompensated risk.
Return generated independent of the broader market's movement. This is what you are paying for.
5. Can you automate it?
If a platform gives you a "Buy" signal via email at 2:13 PM, and you are in a meeting, you miss the trade. By the time you buy at 3:00 PM, the edge is gone. Good tools integrate directly with brokerages (like Interactive Brokers) via API to execute without human delay.
Red Flags to Walk Away From
- "90% Win Rate": High win rates are usually achieved by taking 1% profits and holding losing trades indefinitely until they bounce back (or blow up the account).
- No live, forward-tested track record: If they have been selling the software for 3 years, they should have 3 years of real performance data, not just backtests.
- Testimonials over Data: If the homepage features videos of guys in rental Ferraris instead of drawdown statistics, close the tab.
