The numbers computed.
The story explained.

Roos Research is a pocket research desk. Every statistic — indicators, fundamentals, comparisons — is calculated in code and never guessed. Then AI reads those numbers back to you in plain language.

The approach

Two halves of real research

Price math alone isn't enough — and an AI that invents numbers is worse than useless. Roos Research keeps them separate, and does each one properly.

Quantitative

Every number, computed in code

Statistics and technical indicators are calculated deterministically in Python — reproducible, testable, never hallucinated. Fundamentals sit alongside price and momentum as first-class data.

Qualitative

The story only AI can tell

The AI layer interprets those computed numbers in plain language and brings in what math can't — business operations, news, sentiment, and how investors actually perceive a company.

Watch Roos read a real stock

Every layer computed, each explained in plain language, then reconciled into one brief. Here's an actual analysis of NVIDIA — the real output, not a mock-up.

Roos walks price, technicals, fundamentals and news, then weaves them into a single honest read. Here that read is mixed — and it says exactly why. That's the posture: research, not cheerleading.

Mixedquant + news, synthesized

NVDA's chart pullback and news-flow jitters sit against still-exceptional fundamentals, leaving the Aug. 26 print as the tension-breaker.

A short-term bearish alignment — below both moving averages, negative MACD — echoes recent share weakness, while neutral RSI and still-positive 1–3 month returns suggest a pullback within a range rather than a breakdown. Fundamentals remain exceptional, but a forward P/E near 15.6 leans on ~98% earnings growth landing.

Bull case

  • Earnings growth (214.5%) far outpaces revenue (85%) — scaling leverage, backed by Microsoft's data-center capex.
  • Forward P/E ~15.6 vs trailing ~31 means a growth normalization is already priced in.

Bear case

  • Price below both averages with a bearish crossover, mirroring an ~8% three-month decline.
  • Rich multiples (EV/EBITDA 29x, P/B ~25x) leave little margin if growth disappoints.
