    Hi Gumshoe. New to the game of options. Any chance you can walk me through what you did?

    The Exact (EXAS) short was a terrible idea by Tilson. Fundamentally he simply didn’t understand the company, the problem or the solution.
    I’ve been long the company since 2008 and written about it on MarketWatch more than once: http://www.marketwatch.com/story/a-very-exact-opportunity-in-biotech-2014-04-04
    A few things. The “ick” factor is just funny. Compared to an FIT, it’s far less “icky.” I think compared to a pipe in the back end it’s less “icky” too.
    Let’s look at numbers, Reimbursement came in at $498/test by CMS. The retail price will drag CMS price slowly HIGHER over time as that’s how the process works after initial pricing,
    FIT largely took over the FOBT market in just a few years. Cologuard includes an FIT and will take over the FIT market about as fast. With an uptick in compliance that is being pushed by ACA, this test will be doing about 4m annually by decade end. That means about $6 EPS.
    That doesn’t include international sales or pipeline development which is going to be robust with a test for pancreatic cancer and stomach cancer destined for Asia (stomach cancer is more pervasive there).
    The company is cash rich, has great management and connections, a huge market it will likely dominate and a pipeline that is impressive.
    The short thesis for EXAS is a bad one. You might choose not to invest in EXAS, which I think gets into the $60 – $100 range by decade end, but at least stick to betting against bad companies with deteriorating fundamentals, not good ones that might or might not be great.

  3. FYI, EXAS has quietly doubled in the past couple months (though it’s still well below where it was in the Fall of 2014, when it was such a “hot ticket” stock and Tilson talked about his short thesis). Here’s a summary of a note from one of the analysts that follows the stock:

    “EXACT Sciences (EXAS 12.46) target raised to $15 from $10 at Mizuho. Firm notes EXAS posted a strong, well executed quarter as test volumes exceeded guidance and estimates. While that helps lower the 2H ramp needed to hit full year test guidance, the ramp remains significant and remains an area of concern for us. They also think valuation has now returned to frothy levels, leaving little room for error. They raise their PT on the solid results, but they remain on the sidelines, and prefer CPHD as a molecular diagnostic play” (from Briefing.com)
