klar

Klar turns Claude into a portfolio analyst. Attach a positions export from your brokerage (Fidelity, Schwab, Vanguard, Robinhood, Interactive Brokers and many international brokers) or type your holdings, and Klar runs the numbers on real market data while Claude explains what they mean.

• Performance and risk: returns vs the S&P 500 or a benchmark you choose, from 1 month to 10 years, growth rate, volatility, worst drawdown and recovery, Sharpe and Sortino ratios, beta, what drove returns and risk, correlations, sector exposure and a risk/return map.
• Factor analysis: Fama-French 3- and 5-factor models show how much of your return comes from the market, company size, value, profitability and investment style, and whether any alpha is statistically meaningful.
• Downside risk: historical Value at Risk and expected shortfall, and how the portfolio did in past crises (dot-com, 9/11, 2008, COVID, 2022 and more), from real prices only. If a holding wasn't trading yet, Klar says so instead of estimating, and you can pick a stand-in.
• Valuation: P/E, forward P/E, P/B and P/S (combined the way fund providers do), dividend yield, ROE, margin, earnings growth and debt/equity vs the benchmark, and which holdings you pay most for relative to their earnings.

Results appear in an interactive dashboard in the conversation; change the period, benchmark or factor model and Claude sees the update. One tool, get_view_data, is called only by the dashboard to fetch chart data, which keeps large chart series out of the conversation.

No account or sign-in. Klar stores no portfolios and keeps no database: holdings are processed per request and results are held in memory for up to an hour so the dashboard can draw its charts. Data comes from Yahoo Finance and the Kenneth French Data Library. Klar provides information and analysis, not financial advice.
