Hi Product Hunt 👋
Most insider-trading sites stop at the headline: "a director bought $2M in shares." I always wanted the next step: is this normal for this person? Were other insiders selling? Was it pre-planned? And how did buys like this actually turn out?
So I built InsiderPrint. Press ✦ Spy on any trade and it checks the SEC filing and its fine print, the insider's own history, what other insiders did in the last 90 days, and similar past buys since 2020, then lays out the evidence for and against.
Two things I cared about:
• No AI writes the reports. It's fixed rules on public SEC data, so the same filing always gets the same answer.
• It always shows the case against. Only about 46% of insider buys beat the S&P 500 over 90 days, so the "against" side matters.
There's also an Insider Time Machine (pick buys from a past week with no hindsight, then fast-forward 90 days) and Challenge My Thesis (it argues against your view first).
It's free, no signup, and not financial advice. I'd love to hear what other checks you'd want it to run.
I built InsiderPrint because every insider-trading tracker I tried did the same thing: “CEO bought $5M of stock 🚀” and nothing else. No context, no downside.
The problem is that most insider buys don’t beat the market. In our data only about 46% of them beat the S&P 500. So an insider buy alone isn’t a signal. The context is.
So I built Spy Mode. Press Spy on any insider trade and in a few seconds it:
checks it against the original SEC Form 4 (every result links back to the filing)
looks at the insider’s own track record and what the other insiders are doing
finds similar past buys and how they did against the S&P 500
shows the case against the trade, not just the case for it
It’s rules on public SEC data, not a black box, and it’s free with no signup.
A few other things to try: Time Machine (pick insider buys from the past and see how they would have done) and Challenge My Thesis.
I’d love honest feedback:
What would make you trust a signal like this more?
What’s missing that you’d check before acting on an insider buy?
Not investment advice, just a faster way to do the homework.
