# PRAAMS > PRAAMS Personal turns risk and return of any stock, bond or ETF into one PRAAMS Ratio, so individual investors can research ideas, screen assets and build portfolios without spreadsheets, on web and mobile. PRAAMS is a risk-aware investing platform by PRAAMS SL (Andorra) with a European entity PRAAMS EUROPE SL (Barcelona). Its main product, PRAAMS Personal, scores every asset on twelve risk and return factors — valuation, performance, analyst view, profitability, growth, dividends, default risk, volatility, stress-test, selling difficulty, country risk, other risks — and combines them into the PRAAMS Ratio. Coverage: 75,000+ stocks, 225,000+ bonds, 17,500+ ETFs, 150,000+ funds, 250+ cryptos, 100+ FX. A second service, BehaviouRisk, maps the 19 most common behavioural biases of an investor. The site is available in 20 languages; this file describes the English version. PRAAMS does not provide investment or financial advice, is not a registered investment adviser and does not sell investment products.
