A different (better?) way to track insider trading

Posted on October 6, 2011 at 12:38 pm

I devoted an entire chapter in Tradestream to an investing strategy that mimicked insider trading.  You can check out my insider trading dashboard.

Data’s been really good but the methodology is being question by new research.  While previous research (specifically, that done by Seyhun in his book Investing Intelligence from Insider Trading) focused on buckets of insiders (C-level execs, VP’s, external board members, etc), new findings show that investors can get even more granular.

Like tracking individual insiders granular.follow the insiders

In Decoding Insider Information, Cohen et. al. finds that by identifying profitable, opportunistic (individual) insiders, investors can create a portfolio that yields value-weighted abnormal returns of 82 basis points per month.

Instead of grouping insiders together, this study filters out regular, noisy insider trading, of no value to investors trying to find someone trading on better information.  By looking at insiders who trade opportunistically (every once-in-a-while), piggybacking strategies can mimic just those trades that are imbued with meaningful information (assume the insider knows something.)

  • How to break into the hedge fund industry with an internship

    Posted on October 17, 2011 at 12:45 pm UTC

    It’s not easy to break into the hedge fund industry.

    As today’s guest on Tradestreaming Radio (enrolled in a joint JD/MBA program at Harvard) can attest, even great credentials aren’t enough to land you your first job.

    I will respect our guest’s request for anonymity (he’s still got to fight for a job when he graduates). But this show is jam-packed as he shares

    • what works (and doesn’t) to land a hedge fund internship
    • how you can land a buy-side job without experience on Wall Street
    • how you can standout from other applicants
    • how hard work can help you penetrate the old-boys network
    • how to make sure research gives you an unfair advantage

  • Tradestreaming users like new format of my newsletter (do you?)

    Posted on October 16, 2011 at 2:34 pm UTC

    If you haven’t noticed recent changes (or are not yet subscribed) to my weekly newsletter (Sundays), it appears that some recent tweaks to the format are being well received by the rest of us.

    The point of my weekly email is to help you quickly get a feel for all the cutting edge news and analysis impacting today’s serious investor.

    I’ve begun adding more links/news and categories including:

    • investment products
    • social media, technology and investing
    • investment strategies and research
    • the financial advisory business
    • investor behavior

    You can see an example here and subscribe here.

    By the way, I didn’t just randomly pick the new categories above — I’ve spent a lot of time thinking about how investors learn to become better and how this information breaks down into categorization.

    The changes have resulted in a slightly higher open rate (how many people are opening my weekly message) and and almost double the numbers of clicks on links. I take that as a good thing.


    Are you reading my weekly Tradestreaming newsletter? What do you think — do you like the changes?

    What would you like to see more of from me?  Let me know in the comments below.
