Biotech Investors: Please Don't Make This Mistake

Trying to accurately value a biotech stock isn't just difficult -- sometimes it seems downright worthless. After all, how can investors even try to value a company that hasn't booked a dollar in revenue?

In the following video, Brenton Flynn walks through a commonly used method for valuing biotech stocks and offers a word of caution for investors in companies like Arena Pharmaceuticals (NASDAQ: ARNA  ) , Threshold Pharmaceuticals (NASDAQ: THLD  ) , and Pharmacyclics (UNKNOWN: PCYC.DL  ) , which are waiting on lucrative milestone payments.

Is Arena's reward worth the risk?
With Belviq's FDA approval now a distant memory, investors are scrambling to decide whether to buy or sell Arena. In the Fool's premium research report, senior biotech analyst Brian Orelli takes you through a comprehensive look at this contentious stock, including its massive opportunity, potential pitfalls, and key reasons to both buy and sell.

    First of all're a nut bar!

    Don't talk about earnings until the stock has been allowed to launch!

    ARNA is going to market most likely March 4th 2013.

    Maybe let them go to market......

    Then comment on revenue!

    We'll wait.... then we'll see..... VVUS will be crushed!

    ARNA will get out of the gate running at high speed.

    They're ready to go right out of the gate with marketing.... and the product is now in the pharmacies ready to be sold!

    biggest problem with the fools is that none of their anal ysts have enough years behind them to have

    legitimacy. yes, you can run various programs and

    Oh, hey its Comrade Flynnovsky, the "Health Bureau Chief". Which just his to show you can make a dog sound important by giving it a title but its still a dog.

    I used to respect Motley Fool back in the day but it seems they have been steadily losing their way with garbage like this, for example.

    How ironic is it that the the opening basically warns speculators but how is this accomplished?
