Bullrun: Global Stock & UCITS ETF Research
With Bullrun, Claude can research stocks and ETFs from around the world, with no account or API key. It covers about 30,000 listed companies in the US, Europe and Asia and more than 18,000 ETF listings, including the European UCITS funds that many US-focused tools leave out. Ask Claude to find a company by name, ticker or ISIN, screen for stocks, read a company's financials, price history and news, check its risks and its suppliers, customers and competitors, or look up a country's economic data. For ETFs it can compare costs, holdings and overlap, and show where a fund is listed. Each figure comes with its date, period and currency, and anything missing is marked as unknown instead of guessed. Risk scores and valuation models describe the numbers; they are not investment advice. Prices are daily closes, not live quotes. Free use includes 700 successful tool calls in any 30 days per network, and failed calls don't count.
