BuySide Digest - Hedge Fund Letter Database vs IBorrowDesk
Trying to decide between BuySide Digest - Hedge Fund Letter Database and IBorrowDesk? Here's how they compare on pricing, features, and platforms — and which one fits the way you invest.
BuySide Digest - Hedge Fund Letter Database
Best for stock ideas and news
Free, searchable database of hedge-fund investor letters with filters by fund, CIO, ticker, keyword, theme, and quarter. The broader BuySide Digest site remains active in 2026 with fresh posts and a pitch/13F workflow. Includes BSD 13F tools, fund and ticker follows, email updates, and curated investment pitches. Aggregates publicly available letters; no paid tier or API publicly documented.
IBorrowDesk
Best for short interest
Tracks stock-loan availability and borrow fee data as reported by Interactive Brokers (IBKR). Updates roughly every 15 minutes during North American trading hours and hourly elsewhere on weekdays. The data reflects IBKR only and not the wider market. The site is unaffiliated with IBKR; displayed quotes are provided by IEX. A paid Patron tier adds longer history, CSV exports, and more tracking capacity.
Outbound links may include affiliate or sponsor codes.
