10X EBITDA - Hedge Fund Presentations

DetailsVisit site

10X EBITDA - Hedge Fund Presentations is a free archive of value-investing, activist, and hedge-fund pitch decks for people who want to study how professional investors build stock theses. It is best treated as an educational idea and case-study library, not as a live market-data product, screener, portfolio tool, or source of current investment recommendations.

Dividend Watch

DetailsVisit site

Dividend Watch is a web-based dividend and portfolio tracker for long-term income investors who want dividend forecasts, calendars, DRIP tracking, safety scores, stock and ETF research, and broker sync in one place. It is strongest for dividend portfolio planning and paid safety-score workflows, while the free tier is intentionally small and the platform is not a broker or real-time market terminal.

ETF Insider

DetailsVisit site

ETF Insider is a web-based ETF, mutual fund, and stock portfolio visualization tool for investors who want to see holdings overlap, concentration, correlations, factor exposure, and efficient-frontier style portfolio tradeoffs. It is strongest for diagnosing hidden ETF overlap in U.S.-listed portfolios, with full holdings depth, Excel export, API access, and white-label options gated by Pro or Enterprise plans.

Bridgewater Associates

DetailsVisit site

Bridgewater Associates is a global macro investment manager whose public website is mainly useful as a free research and insights source, not as a self-serve investing product. It is strongest for readers studying institutional macro thinking, Daily Observations, whitepapers, videos, Pure Alpha, All Weather, risk parity, inflation, monetary policy, debt cycles, and systematic investing, but most investors cannot directly access Bridgewater mandates through the site.

Corner of Berkshire & Fairfax (COBF)

DetailsVisit site

Corner of Berkshire & Fairfax is a long-running value-investing forum built around Berkshire, Fairfax, stock ideas, books, and long-form investor discussion. Public boards are useful for idea discovery, while deeper rooms and participation sit behind a one-time lifetime membership.

Finimize

DetailsVisit site

Finimize is a consumer investing newsletter and mobile app for investors who want concise market news, investing education, analyst-backed ideas, model portfolios, and an easier daily research habit. It is strongest when the goal is understanding what matters in markets without opening a data terminal: the free newsletter covers short daily finance news, while Pro adds investment theses, entry points, risks, position sizing, ongoing coverage, live ideas, model portfolios, and performance tracking. It is a content and ideas product, not a broker, portfolio accounting tool, public API, or deep analytics platform.

Investment Masters Class (MastersInvest.com)

DetailsVisit site

Investment Masters Class is a free educational site focused on timeless investing lessons, curated reading, investor letters, and essays about great investors and business builders. It is useful for improving process and judgment, not for stock screens, market data, trade signals, or personalized financial advice.

Monexa

DetailsVisit site

Monexa is a low-cost AI stock analysis workspace for investors who want screening, company dashboards, financial statements, DCF models, news, calendars, transcripts, SEC filings, analyst estimates, insider transactions, 13F Whale Tracker views, and congressional trading in one web app. Search intent is strongest around AI stock analysis, AI stock screeners, and whale tracking, so the copy should emphasize workflow depth without overstating the AI. Free access is useful but gated; Pro adds longer history, fuller transcripts, AI tools, saved models, exports, and deeper ownership views. Market data may be delayed, and AI output should be checked against filings, transcripts, and assumptions.

OptionCharts

DetailsVisit site

OptionCharts is a web-based options analytics workspace for visualizing strategy payoff, Greeks, implied-volatility skew, expected moves, gamma and delta exposure, contract history, and market-wide options trends. It is best for traders who want options research and chart exports, not brokerage execution, a public options-data API, or guaranteed real-time access on every plan.

ORTEX

DetailsVisit site

ORTEX is a market-data and analytics platform best known for short interest, securities lending, options flow, and trading-signal context. It fits active investors, analysts, and data teams that need more than a basic quote page, with deeper web-app and API access moving behind paid tiers.

Prospero.ai

DetailsVisit site

Prospero.ai is a free mobile-first AI signal app for U.S. stocks and ETFs, with proprietary short-term and long-term signals, daily screens, stock picks, watchlists, notifications, and education. It is useful for beginner-friendly signal discovery, but it is not full fundamental research, broker sync, a web terminal, public API, or proof that a signal will work.

StockAlert Pro

DetailsVisit site

StockAlert Pro is an alert-first stock and ETF monitoring platform with configurable alerts, watchlists, AI equity reports, API keys, webhooks, SDKs, and integrations. It is useful when investors or builders need notifications and automation around price, technical, volume, fundamental, dividend, and time conditions, but it is not a broker, full research terminal, or portfolio accounting system.

The Zen of Investing

DetailsVisit site

The Zen of Investing is a free, niche special-situations site focused on upcoming and recent spinoffs. It is useful for event-driven investors who want curated links to press releases, investor decks, prospectuses, filings, and SEC feeds before doing deeper valuation work elsewhere.

Visual Capitalist

DetailsVisit site

Visual Capitalist is a publisher of data-rich infographics and explainers covering markets, commodities, technology, macroeconomics, and global business themes. It is strongest as visual context for research and presentations, not as a queryable market-data terminal or investment-advice product.

Visualping

DetailsVisit site

Visualping is a website-change monitoring and alerting platform that investors, compliance teams, and analysts can use to watch regulator pages, investor-relations pages, pricing pages, competitor pages, and other web sources. It is best treated as a web-native monitoring layer, not a market-data feed, normalized financial database, broker, or guarantee that every page change is investment-relevant.

Damodaran Online (NYU Stern)

DetailsVisit site

Damodaran Online is Aswath Damodaran's free NYU Stern valuation resource for investors, students, and analysts who need downloadable datasets, valuation models, equity risk premiums, country risk premiums, betas, multiples, and corporate-finance teaching material. It is a trusted manual research library, not a polished stock terminal, screener, alert product, or real-time data feed.

13F Insight

DetailsVisit site

13F Insight is an SEC-filings intelligence platform for investors who want to track institutional 13F holdings, Form 4 insider trades, 13D/G ownership, watchlists, smart-money alerts, and AI answers grounded in filing citations. It is strongest for hedge-fund and institutional-ownership research, but 13F filings are delayed by design and AI summaries should be checked against the underlying SEC documents.

Capitol Trades

DetailsVisit site

Capitol Trades is a free public web app from 2iQ Research for tracking U.S. politician trading disclosures under the STOCK Act. It is strongest for investors, journalists, and researchers who want to filter congressional trades by politician, issuer, chamber, party, committee, state, asset type, transaction type, sector, size range, and filing details, but disclosure timing can lag trades and reported amounts are ranges rather than exact fills.

CEO.CA

DetailsVisit site

CEO.CA is a Canadian small-cap investor community and market-data platform for traders and investors following TSX, TSXV, and CSE issuers. It is strongest for ticker chat rooms, watchlists, real-time news, SEDI insider filings, private placements, audience analytics, mobile access, and paid Level II market depth, but community posts are not research and Pro pricing depends on which Canadian exchanges you need.

ChartMill

DetailsVisit site

ChartMill is a browser-based stock screener, charting, ratings, alerts, and research platform for self-directed traders and investors screening U.S., Canadian, and European stocks and some ETFs. It is strongest for repeatable technical and fundamental screen workflows, swing-trading ideas, watchlists, alerts, market dashboards, ChartMill ratings, and strategy templates, but paid access does not turn it into a real-time broker or full portfolio accounting system.

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.

Dune

DetailsVisit site

Dune is a crypto and onchain analytics platform for SQL dashboards, decoded blockchain data, APIs, alerts, uploads, teams, and AI-agent workflows. Use it when you want to build or automate custom onchain analysis across many blockchains rather than consume a fixed market-data screen.

ETF Action

DetailsVisit site

ETF Action is an ETF analytics platform for advisors, asset managers, and ETF-focused investors who need classification, look-through holdings, overlap, flows, model portfolios, 13F screening, exports, and enterprise data workflows. Use it when ETF research and model construction need more depth than a free quote page.

European Central Bank (ECB) — Statistics & Data

DetailsVisit site

European Central Bank Statistics & Data is the official ECB source for euro-area statistics, policy rates, FX reference rates, yield curves, inflation, macro indicators, downloads, and SDMX API access. Use it when you need primary-source European macro and rates data rather than investment-app commentary.

FinancialJuice

DetailsVisit site

FinancialJuice is a live market news and squawk service for traders who need fast audio headlines, real-time text updates, macro calendar context, and market-moving event alerts across equities, rates, FX, commodities, crypto, and futures. It is strongest for time-to-awareness around economic releases, central-bank news, geopolitical headlines, and session prep rather than deep valuation work. Free access exists, but the real-time workflow is mainly a Pro/Elite decision with paid voice squawk, text headlines, calendar tools, news-team access, and optional Market-on-Close imbalance data.

Gainify

DetailsVisit site

Gainify was an AI stock research and portfolio platform for global equities, combining screening, S&P Global-powered data, stock reports, valuation charts, AI analysis, earnings summaries, watchlists, portfolio tracking, investor activity, and insider/Congress trading signals. It should now be treated as a discontinued product: the canonical homepage says Gainify.io is closed and the service is no longer available. Use this profile for historical product research, comparison pages, and routing users toward live alternatives, not as a current signup recommendation.

In Practise

DetailsVisit site

In Practise is a qualitative investment research library built around executive interviews, transcripts, surveys, and company learning journeys for long-term fundamental investors. It is useful when you want business-model context, operating detail, customer or competitor insight, and management-level perspective to complement filings, earnings transcripts, and valuation work. The free plan gives a limited way to sample the library, while full access and private interview workflows are paid and sales-led.

Investopedia

DetailsVisit site

Investopedia is a free finance education and market news publisher with a widely searched Stock Simulator for paper trading. It is best for beginners, students, educators, and self-directed investors who want definitions, explainers, market context, newsletters, calculators, and a virtual-money environment before using a real brokerage account. The simulator is useful for practice, but it uses delayed data, limited exchange coverage, and limited options functionality, so it should not be treated as live execution, professional trading infrastructure, or investment advice.

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.

Letters and Reviews

DetailsVisit site

Letters and Reviews is a free personal curation site for fund manager letters, hedge fund letters, shareholder letters, ticker mentions, and quarterly 13F pages. It is useful for value investors and researchers who want a lightweight starting point for primary-source idea generation before reading the original manager commentary or filing. Treat it as a curated link hub, not a normalized holdings database, alerting product, full-text research platform, or investment recommendation service.

LuxAlgo

DetailsVisit site

LuxAlgo is a TradingView-focused technical-analysis suite for traders who want packaged indicators, price-action overlays, screeners, alerts, oscillator tools, calculators, and AI-assisted backtesting. It is built for chart-based workflows across stocks, ETFs, futures, commodities, currencies, and crypto.

Marketlog

DetailsVisit site

Marketlog is a web and mobile portfolio tracker for retail investors and active traders who want manual or broker-connected portfolios, dividend tracking, goals, target allocation, benchmarking, forecasts, alerts, market pages, calendars, and public or private portfolio sharing. It is useful for monitoring holdings and portfolio behavior across asset types, especially when users want mobile access and community portfolio browsing. It is not a broker, exchange, fiduciary, investment adviser, or public market-data API.

MarketScreener

DetailsVisit site

MarketScreener is a broad global market news and stock research portal with quotes, watchlists, screeners, charts, calendars, analyst data, company financials, transcripts, ESG ratings, insider data, newsletters, and model portfolio content. It is useful for retail investors who want one content-heavy site for daily monitoring and global stock discovery. The tradeoff is tier gating: advanced screeners, reports, portfolios, decision-support tools, and some content require paid Access, Premium, or Expert subscriptions, with pricing that can vary by region and promotion.

Observatory of Economic Complexity (OEC)

DetailsVisit site

The Observatory of Economic Complexity is a trade-data and economic-complexity platform for exploring countries, products, industries, exports, imports, rankings, and trade relationships through rich visualizations and an API. It is useful for macro, supply-chain, and thematic research, not security-level stock analysis.

PwC - IPO Watch EMEA (all editions)

DetailsVisit site

PwC IPO Watch EMEA is a free quarterly publication that summarizes IPO volume, proceeds, sectors, countries, exchanges, top deals, and market commentary across EMEA principal stock markets. It is useful for regional IPO context and citations, but it is a PDF-first report rather than a live IPO calendar, interactive screener, or public API.

Semrush

DetailsVisit site

Semrush is an SEO, marketing intelligence, website traffic analytics, and AI search visibility platform that investors can use as alternative data for search-dependent companies, publishers, agencies, ecommerce, SaaS, and consumer brands. It has large commercial demand around Semrush, pricing, API access, website traffic analytics, SEO APIs, and AI search visibility, but it remains a marketing platform rather than investing software. Use it for keyword demand, competitor visibility, traffic proxies, and channel analysis, then validate against filings and first-party metrics. It is not a broker, portfolio tracker, valuation model, official fundamentals provider, or direct measure of company revenue.

Smartkarma

DetailsVisit site

Smartkarma is a premium investment intelligence platform for professional investors, asset managers, banks, and accredited/private investors who need independent research, specialist analysts, data tools, watchlists, and real-time alerts. Search intent around Smartkarma Pro, pricing, independent investment research, and investment intelligence platforms is commercial, so the copy should be direct about qualification and cost. A Preview Pass provides limited discovery, while Pro is documented at USD 10,950/year per user and Premium/Data or Plus access can require request or onboarding workflows. It is not a retail stock screener, broker, portfolio accounting system, or low-cost news site.

Special Situation Investments (SSI)

DetailsVisit site

Special Situation Investments is a niche event-driven research site and paid community for investors looking for special-situation ideas, active discussions, high-conviction writeups, catalyst timelines, upside targets, and member commentary. Search intent around special situation investments, event-driven ideas, and special-situations newsletters is commercial but small, so the copy should make the membership model and strategy focus clear. Past ideas are free, while active ideas, research, comments, and updates require paid membership. It is not a broad stock screener, diversified portfolio tool, broker, public API, or recommendation service for every investor.

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.
