Best Free Corporate Actions & Special Situations Tools for Investors

SEC EDGAR - Company Filings (Full‑Text Search & Search Filings)

DetailsVisit site

SEC EDGAR Search is the official free source for U.S. public company, fund, insider, ownership, prospectus, and XBRL filing research. It is strongest as the source of truth for SEC filings, full-text search, latest filings, RSS feeds, CIK lookup, and data.sec.gov JSON APIs, but raw filings still require parsing and automated access must follow SEC fair-access rules.

Börsdata

DetailsVisit site

Börsdata is a Nordic-first equity analytics, screening, and data platform for investors who want long-history fundamentals, thousands of ratios, strategy screens, ownership data, insider and short-selling context, technical charts, reports, watchlists, calendars, and API or spreadsheet access. It is strongest for Nordic stock research, while global coverage, holdings data, Excel/Sheets workflows, and REST API access depend on paid tiers and professional users are routed to Enterprise.

Chittorgarh.com

DetailsVisit site

Chittorgarh.com is a long-running Indian primary-market portal for retail investors following IPOs, FPOs, NCDs, bonds, broker reviews, subscription data, and grey-market premium snapshots. It is strongest for quick India IPO context across web and mobile apps, but GMP is unofficial and unregulated, the site is publisher-style rather than a normalized database, and there is no public API.

Dilution Tracker

DetailsVisit site

Dilution Tracker is a small-cap research tool for monitoring share-supply risk from shelves, ATMs, warrants, convertibles, S-1 offerings, reverse splits, and related filings. Use it when dilution risk can make or break a trade, especially in volatile U.S. small-cap names.

ETF.com

DetailsVisit site

ETF.com is an ETF media and research site with a U.S. ETF screener, comparison tools, fund flows, holdings search, watchlists, Portfolio Builder, launches, closures, and ETF education. Use it when you want ETF discovery plus editorial context from a known ETF-focused brand.

FDIC BankFind Suite (BankFind)

DetailsVisit site

FDIC BankFind Suite is the official free FDIC source for looking up FDIC-insured banks, branches, histories, structure changes, failures, financials, Summary of Deposits data, APIs, and bulk downloads. Use it when bank research needs primary-source U.S. government data rather than a commercial bank screener.

Hong Kong Exchanges and Clearing (HKEX)

DetailsVisit site

HKEX is the official Hong Kong exchange source for listed-company announcements, HKEXnews filings, corporate calendars, market alerts, delayed public quotes, and licensed market data services. It is strongest when investors and data teams need primary-source Hong Kong disclosures or official exchange feeds rather than third-party summaries. Public pages are useful and free, but real-time, historical tick, full order book, and redistribution workflows require paid HKEX Market Data Services, Data Marketplace products, and licensing.

InvestorGain

DetailsVisit site

InvestorGain is a free India primary-markets portal for IPO GMP, live IPO subscription status, allotment links, anchor investor data, IPO performance history, rights issues, NCDs, sovereign gold bonds, and broker comparisons. It is useful for retail investors checking mainboard and SME IPO demand signals before verifying official exchange, registrar, RHP, and broker details. Treat Grey Market Premium as unofficial sentiment data, not a guarantee of listing gains or a complete investment case.

IPOWala.in

DetailsVisit site

India-focused IPO information portal (NSE/BSE context) with a live IPO Grey Market Premium (GMP) page and other IPO tracking pages (subscription status, allotment links, listing-performance tables, and buyback lists). GMP content is stated as informational only; the site states it does not trade, deal, or support grey-market / “subject-to” transactions, and recommends consulting a SEBI-registered advisor. The live GMP page returned HTTP 200 on 2026-07-01 and showed separate mainboard and SME GMP sections with updated timestamps.

ListingTrack

DetailsVisit site

ListingTrack is an event-driven market-intelligence platform for tracking IPOs, SPACs, de-SPACs, public M&A, pre-IPO pipelines, listing events, and related themes. It is useful for investors who want structured listing-event data and watchlist workflows that generic news feeds can miss. It is not a full fundamentals terminal, valuation modeler, broker, portfolio accounting system, or unrestricted data API.

Macrotrends

DetailsVisit site

Macrotrends is a web-based historical charting, stock research, and macro data site for investors who want long-run stock prices, fundamentals, dividends, indices, commodities, exchange rates, interest rates, global metrics, and a simple stock screener. It is useful for quick visual context and historical series, especially when users need low-friction charts rather than a full research terminal. Some data, charts, downloads, or resources require Premium Access, with pricing shown at checkout and no monthly billing recorded in the current terms.

RetailRoadshow

DetailsVisit site

RetailRoadshow is a NetRoadshow-operated portal for viewing SEC-compliant electronic roadshow videos and prospectus materials for registered public offerings, primarily IPOs. It is useful for hearing issuer management presentations during active offerings, but access depends on availability, registration, and sometimes deal-specific entry codes.

SEDAR+ (CSA Public Filings - Canada)

DetailsVisit site

SEDAR+ is the official Canadian Securities Administrators public-filings system for Canadian issuer and investment-fund disclosure. It is useful when investors need primary-source Canadian filings, prospectuses, reporting-issuer status, cease-trade orders, or disciplined-list checks, but it is not a global filings terminal, broker, ticker-first screener, or public data API.

Special Situations Digest

DetailsVisit site

Special Situations Digest is a weekly global event-driven research workflow for investors sourcing activist campaigns, strategic reviews, spin-offs, going-private deals, divestitures, tender offers, restructurings, and M&A across 30+ countries. It is built for fast idea generation and triage, with structured situation cards, a searchable database, spreadsheet/PDF/JSON exports, Copy-for-LLM, and a real-time EDGAR/OTC live feed. It is not a full diligence replacement, valuation modeler, broker, or personalized investment-advice service.

Stock Spinoff Investing

DetailsVisit site

Stock Spinoff Investing is a niche research site and paid newsletter for investors focused on spin-offs and related special situations. Its free value is the upcoming and completed spin-off calendar; SSI Premium adds roughly one new idea per month, weekly updates, live monthly video Q&A, Discord access, and historical newsletters. Search intent around stock spinoff investing, stock spinoff calendars, and special situations newsletters is small but highly commercial, so the copy should stay precise. It is not a broad stock research terminal, portfolio construction tool, broker, public API, or substitute for filing review and independent valuation.

Tijori Finance - Ideas Dashboard

DetailsVisit site

Tijori Finance - Ideas Dashboard is an India-focused stock-idea and market-monitoring workspace built around curated event, fundamental, and operational-data signals. It can surface research leads quickly, but the deeper workflow is Premium-gated and the ideas still need independent verification.

Trendlyne

DetailsVisit site

Trendlyne is an India-first equity research and portfolio platform with screeners, DVM scores, analyst forecasts, alerts, backtests, transcripts, broker sync, and options tools. Global plans add U.S. market coverage, but the strongest fit is still Indian market research with tiered data downloads and alert limits.

BamSEC

DetailsVisit site

BamSEC is a web-based SEC filings and transcripts research platform for investors and analysts who need faster EDGAR workflows. It is strongest for document search, filing redlines, table extraction, transcripts, insider and institutional ownership, watchlists, alerts, highlights, and source-link sharing, with most professional workflows gated behind Pro or Enterprise.

GuruFocus

DetailsVisit site

GuruFocus is a value-investing research platform for investors who want global fundamentals, valuation tools, GF Score, GF Value, screeners, backtesting, guru and institutional holdings, insider trades, portfolio tracking, spreadsheet add-ins, and data/API access. It is strongest for fundamental and value-oriented research rather than brokerage execution.
