- Reed Hastings (CEO, Netflix) sold $15M of his shares 2 days before a class action lawsuit hit the company and the stock crashed

- Mark Zuckerberg (CEO, Facebook) sold $296M of his shares before the stock plunged

I was curious to see if I can discover patterns using SEC filings of type 4 (changes in ownership, aka insider trades) and developed a Python app to do so.

Do you think that's a path worth exploring further? Maybe even backtesting and developing an algo to trade on signals derived from SEC filings? Did anyone already test a similar approach using SEC filings as trading signals?

Looking for feedback. I developed

https://newsfilter.io

It's a real-time news filter and aggregator.

You can create filter channels (eg show only articles containing "Acquisition" published in Israel). Over 100 news sources from 30 countries are supported so far (eg Reuters, Bloomberg, TechCrunch, HN, Times, etc.).

So far, its used by 12 linkedIn influencers in Australia and Canada, 2 hedge fund managers in UK, and a couple of financial news and tech bloggers in India and USA. I personally use it to stay on top of news related to my investments in US equities.

Is it obvious how the filters work? How much would you pay for it? What features are missing?
