BamSEC vs WhaleWisdom
Trying to decide between BamSEC and WhaleWisdom? Here's how they compare on pricing, features, and platforms — and which one fits the way you invest.
BamSEC
Best for improved filings and diff view
Web-only SEC filings and transcripts research platform focused on EDGAR documents, table extraction and ownership analytics. Browsing all electronically filed SEC documents is free, while premium tools such as Document Search, table downloads, document comparison, insider and institutional ownership views, and advanced alerts are part of the Pro and Enterprise subscriptions (Pro is $69/month billed annually with a 7-day free trial; Enterprise adds team features like consolidated invoicing, usage reporting and priority support).
WhaleWisdom
Best for 13d/13g and investor holdings
Aggregates 13F filings, Schedule 13D/G data, Form 4 insider activity, and institutional ownership tools so investors can follow fund positioning, build watchlists/filer groups, export data, and backtest crowding strategies. Free access remains available with limited tools and recent 13F history; the pricing page says there are no trial accounts, while much of the site can be explored for free. Current paid plans are Standard at $90/quarter or $300/year, Pro at $150/quarter or $500/year, and Enterprise by quote for team access, unlimited 13F API access, live data feed calls, and nightly FTP files.

Comparison snapshot
Standout features
What BamSEC does best
- Specialized web platform for working with SEC filings and earnings transcripts, marketed as making “financial research easier” for thousands of subscribers including major investment banks and buy-side firms.
- Covers all SEC filings submitted electronically via EDGAR from 1994 onward in their original, unmodified form, with new filings typically processed within a minute or two of being filed (and by end of day for confidential filings that later become public).
- All-company screening tools let you instantly search across millions of documents for any term, using filters like industry, market cap, document type and Watch List, plus advanced operators (exact phrases, boolean logic, proximity / distance between words) and email alerts for new matches.
- Company-level Document Search shows every mention of a term across a single issuer’s filings and transcripts, with result categorization and an “intuitive workflow” for jumping straight from search hits to the underlying documents without manual Ctrl+F scans.
- Table Tools provide one-click Excel downloads for any table in any filing, including most financial tables beyond the three statements, plus Similar Tables to pull prior versions from older filings and Merge Tables to combine data across periods; downloads are cleanly formatted spreadsheets with no merged cells or styling and data taken directly from the filings.
What WhaleWisdom does best
- Track and analyze hedge-fund and institutional SEC filings including 13F quarterly reports, Schedule 13D/G events, Form 4 insider transactions, Form D, Form 144, N-CEN mutual-fund search, and Investment Adviser/Form ADV search tools.
- Free tier advertises past two years of 13F data, unlimited email alerts, filer groups up to 5 members, stock watchlists up to 5 stocks, backtesting over recent 13F history, and limited access to most site tools.
- 13F database history goes back to the March 31, 2001 quarter / Q1 2001; Standard and Pro unlock earlier historical 13F data, while Standard also lists historical 13D/G data back to 2006.
- Developer API uses the endpoint https://whalewisdom.com/shell/command, requires a registered account and API access keys/signatures or an authenticated browser session, and is limited to 20 requests per minute.
- API commands include quarters, stock_lookup, filer_lookup, stock_comparison, holdings_comparison, export, holdings, holders, and filer_metadata; outputs include HTML, JSON, and CSV depending on command.
