AI reasoning snippet · illustrative

In this sample, the model estimates a 18% discount to the $198.40 fair value. Valuation is supported by a DCF model (WACC 9.2%), a 28x P/E vs. sector avg 32x, and an AI quality score of 84/100 reflecting strong FCF yield (4.2%), expanding services margins (73%), and low leverage (D/E 0.47). Bear case assumes hardware revenue contraction; bull case prices in AI feature monetization.

+ Meta Decision Engine aggregates all 24 agent outputs into a weighted final verdict.

Why it matters: A single LLM prompt can hallucinate. When multiple independent agents covering different domains reach the same conclusion, the probability of a reliable output increases dramatically. This is the same logic behind investment committee votes.

Methodology

How we calculate fair value

Three independent models. Each produces an estimate. The final output is a weighted blend.

1

Discounted Cash Flow (DCF)

40%

Projects 5 years of free cash flow using historical FCF trends from financial statements. WACC is estimated using a risk-free rate proxy (10-year US Treasury) plus an equity risk premium and beta adjustment per sector. Terminal value uses a conservative 2–3% perpetuity growth rate. Not applicable to pre-revenue or negative-FCF companies — model falls back to multiples in those cases.

Note: Not reliable for pre-revenue or negative-FCF companies.

2

Relative Multiples (P/E, EV/EBITDA, P/FCF)

35%

Compares the stock to sector averages using P/E, EV/EBITDA, and P/FCF ratios sourced from Financial Modeling Prep. Applies a quality premium (+10–20%) or discount (−10–25%) based on margin and growth differentials vs sector median. Outliers (>2 standard deviations) are excluded from the peer set.

Note: Sector averages may lag during rapid industry re-ratings.

3

AI Quality Score

25%

Gemini AI scores 12 fundamental factors: revenue growth, margin trend, FCF quality, debt burden (D/E), ROE, ROA, competitive position, management efficiency, earnings consistency, capital allocation, balance sheet strength, and sector tailwinds. Range 0–100. This score adjusts the final fair value up or down by up to 15%.

Note: AI-generated — subject to model error and data quality.
