Fair value as of: Jun 24, 2026
From 1 valuation models · updated 47 days ago
Share price −1.6% over the past month.
Below-average quality, and screening another 31% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($0.1200). The favourable scenario is already priced in.
- Weak quality (27/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Jun 24, 2026.
How to read this chart
60‑month range $0.0600 – $2.01 · fair‑value band $0.0700 – $0.1200 · the $0.1300 price screens above the $0.0900 fair value. Dashed = 300-day average. As of Jun 24, 2026.
Analysis
Signal Advance, Inc (SIGL) currently trades at $0.1300, while our model-based Fair Value estimate is $0.0900, implying the stock looks roughly 30.8% overvalued today. The Quality Score stands at 27/100 (below-average quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Trailing-twelve-month revenue stands at $10.4K. It earns a return on equity of -28.4%. Fundamentals as of Jun 24, 2026
Our scenario range runs from $0.0700 (bear case) to $0.1200 (bull case); at $0.1300, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 71% below its 52-week high and 7% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -45% fair-value upside, at -31%, SIGL screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
