At The Motley Fool, contributor Jordo Bivona writes that "There is no shame in wanting to find cheap investments that pay off in the long run. The trouble is it can be tough to tell what is worth your money and what is cheap simply because it is worthless." In some cases, like Keryx, "the prices are low, but the stocks are worth a great deal. For these stocks, now is the time to buy and hang on until something major happens and the prices soar."
About Keryx, he writes,
...The company still has approximately $30 million in cash to fund operations, and a quarterly burn rate of around $4 million to $6 million, depending on research demands. For the company to succeed with Zerenex, it needs successful trials in its fourth quarter and a new drug application from the FDA.
