Websites to track insider trading

Finviz: I’ve written previously about Finviz’s great stock screener.  They also publish a nice free list of all buys and sells from corporate America here.

Pragmatic Capitalism: Weekly run down on what corporate insider are buying and selling.  Site puts the information in context by comparing trends in insider activity.  Focus is on the macro — not much attention is applied to individual stocks.

CNBC: It’s a shame CNBC’s website doesn’t get more props.  While the cable channel has struggled in getting users to watch their videos on the web, they’ve done a great job with the tools on the site.  One tool, Insider Stock Trading Trends, allows users to get a view — by industry — of who’s buying and selling what.  Also drill down on company stock pages — you can plot insider purchases and sales against stock prices.

GuruFocus: This premium site has a few free lists of insider transactions including all those by CEOs and CFOs.  Paying up to subscribe gives users access to insider cluster buys, insider buys coupled with guru buys, and the triple header — companies buying back their own stock, combined with insider and guru buying. Searchable database of all regulatory filings by corporate insiders.

InsiderCow: Nice free site moving towards more to a pay-to-play model. Subscribers can get real-time info as it gets filed, otherwise free offering provides historical inside information.
