What this score covers. It is a fixed screen of five reported ratios with no valuation input, so a company can score highly while its valuation risk remains elevated. The full report scores valuation separately, as one of nine scored sections. How the score is calculated
Rubicon Technology, Inc. (RBCN) is a Technology company in the Semiconductor Equipment & Materials industry. It has a 67/100 Buy score on our five-factor fundamentals screen. Key strengths include Gross Margin (40.1%), Net Margin (26.1%). Areas to watch: Revenue Growth (-20.9%). The score is a five-factor screen — revenue growth, gross margin, net margin, return on equity and debt-to-equity — each scored against fixed thresholds from a neutral starting point of 50 points. The full report scores nine sections, including moat, free cash flow, dilution and valuation, which this screen does not.
This page score and the strengths and concerns above are produced by deterministic, rule-based calculations from the available third-party financial inputs documented below. AI does not choose the score, strengths, or concerns. Data and automated summaries can contain errors. This is not personalized investment advice. See our methodology and disclaimer.
The calculation starts at 50 points and applies the five fixed adjustments shown below. Missing or invalid inputs contribute no adjustment. A finite provider-reported zero is treated as a measured value and evaluated against that input's displayed threshold. The pre-clamp result is 67; the published result is clamped to a minimum of 10 and maximum of 98, producing 67/100.
| Input | Displayed value | Threshold applied | Adjustment | Data status |
|---|---|---|---|---|
| Revenue Growth | -20.9% | 0% or lower | -5 | Available |
| Gross Margin | 40.1% | > 35% to 50% | +6 | Available |
| Net Margin | 26.1% | > 20% | +10 | Available |
| Return on Equity | 5.6% | > 0% to 12% | +2 | Available |
| Debt/Equity | 0.50 | 0.30 to < 0.60 | +4 | Available |
80 or higher: Strong Buy; 65–79: Buy; 50–64: Hold; below 50: Caution.
These are fixed names for score ranges. The score is not a success probability, recommendation, or forecast, and 80/100 does not mean an 80% chance of a gain.
This page was generated . The provider identifies the latest underlying financial period as December 31, 2022. The displayed market quote is dated October 23, 2026. Generation time is not the same as the date of the underlying filing or market observation.
Financial inputs may be delayed, restated, differently standardized by the data provider, or unavailable. Missing, invalid, or non-finite values receive no positive or negative adjustment rather than being estimated. A finite provider-reported zero is retained and evaluated against that metric's displayed threshold; it is not treated as missing. This can make a sparse-data score less informative. The screen does not capture every business, market, valuation, or portfolio risk, and investors can lose money.

The 67/100 on this page comes from a fixed screen of 5 ratios. The downloadable report is a separate analysis with its own score, built from 9 weighted sections.
Each factor is scored against fixed thresholds from a starting point of 50 points. No factor prices the stock, so valuation is not part of the 67/100.
When the inputs allow, the report also shows a fair-value estimate with its discounted cash flow (DCF) assumptions and a 3×3 sensitivity table, a confidence figure, and the data limitations that reduced that confidence. Its headline label can add a valuation-risk flag next to the fundamental-quality rating.

Rubicon Technology, Inc. clears our thresholds on most of what we measure. The strongest readings are gross margin (40.1%) and net margin (26.1%). It is not unqualified: revenue growth (-20.9%) works against it.
Rubicon Technology, Inc. reported revenue decline of -20.9% year over year, against a Semiconductor Equipment & Materials peer set where scale and pricing power vary widely. A shrinking top line is a direct drag on the score, and it raises the bar for everything else in the model.
