Methodology: Median Downside

Median Downside is the gap between the current price and the median fair value of every model currently active for that company, where the price sits above the median. It is the same number, and the same sign convention, as the verdict on the stock’s own page.

Models: Bayesian DCF, EPV, First Chicago, Markov DDM, ML-RIV, FTNN Topology, and 7 more.

What Should You Know About This US Screen?

What are the most overvalued stocks in 2026?

CirclFi identifies the most overvalued stocks 2026 using 13 institutional-grade valuation models including Bayesian DCF (10,000 Monte Carlo simulations), EPV (Greenwald framework), and EROIC Spread (McKinsey). Rankings update daily from SEC EDGAR filings. The current top-ranked stock is BBIO (BridgeBio Pharma, Inc.).

How does CirclFi rank these stocks?

Stocks are ranked by Median Downside derived from CirclFi's proprietary models. Each model independently processes SEC EDGAR financial data (700+ XBRL tags), FRED macroeconomic indicators, and GDELT news sentiment to produce confidence-weighted fair value estimates. The ranking methodology combines multiple valuation approaches — intrinsic, relative, scenario, and ensemble — for maximum robustness.

How often is the most overvalued stocks 2026 list updated?

This list is recalculated daily after US market close. Every stock is re-valued through all 13 models using the latest SEC EDGAR filings, market prices, and FRED macroeconomic data. Rankings can change daily as new financial data becomes available or market prices shift relative to fair value estimates.

What is the Quality of Company (QOC) score?

The QOC score is a 0-10 composite rating derived from 32 fundamental signals across four pillars: profitability (ROE, ROIC, margins), growth (revenue CAGR, earnings acceleration), stability (earnings volatility, debt coverage), and capital efficiency (asset turnover, free cash flow yield). Higher scores indicate stronger fundamentals. Scores above 7 represent top-tier companies.

How does this list compare to other stock screeners?

Unlike simple screeners that filter by P/E or dividend yield, CirclFi runs 13 independent institutional-grade valuation models on every stock — including Bayesian DCF with Monte Carlo simulation, Greenwald EPV, and McKinsey economic profit frameworks. Each company is scored on 32 fundamental signals drawn from 700+ SEC EDGAR XBRL tags, then re-valued after every US market close. Most retail screeners use one or two metrics; this screen ranks 3,801 US companies on the median of all 13.
