Innovation Signal Index (ISI)
Seeing What Financial Statements Miss
The Innovation Signal Index™ is a framework for measuring whether a company's innovation investment is building or eroding competitive advantage. Using publicly available data, the ISI detects shifts in innovation health 3-5 years before they appear in financial results.
Wall Street's standard metric for evaluating innovation, R&D spending as a percentage of revenue, tells you nothing about whether that investment is working. A company can spend billions on R&D and still lose its competitive position. The ISI was built to answer the question financial statements can't: is the innovation engine accelerating, maintaining, or dying?
How It Works
The ISI analyzes patterns in public filings, patent data, and financial performance to identify signals that precede major shifts in competitive position. The framework was validated through backtesting: we applied the methodology to historical data, generated predictions, and checked those predictions against what actually happened financially. Only metrics that survived this out-of-sample validation were retained.
What the Framework Has Detected
The ISI has been tested across semiconductors, consumer electronics, specialty materials, and enterprise infrastructure. In backtesting, the framework correctly identified competitive decline 5-6 years before it became visible in financial results, detected strategic turnarounds 3-4 years before the market priced them in, and distinguished companies with genuine research investment from those maintaining the appearance of R&D while starving actual innovation.
The framework also identified which commonly used innovation metrics are functionally useless. R&D as a percentage of revenue, the metric analysts cite most often, failed to predict outcomes in any of our test cases.

Who This Is For
The Innovation Signal Index was designed for CTOs, board members, and innovation leaders who need evidence-based arguments to defend long-horizon R&D investment against quarterly earnings pressure. It provides the empirical foundation for conversations about why cutting research to meet short-term targets destroys long-term competitive advantage.
Current Status
The ISI is an active research program. The core financial metrics have been validated through backtesting across multiple industries. An expanded framework incorporating patent quality signals and inventor diversity metrics is in development.
