What happened
Shares of Ardelyx ( NASDAQ:ARDX) were sinking 11.5% as of 10:58 a.m. EDT on Friday. The drop appears to be a case of "buy the rumor, sell the news." The biotech stock has soared in recent weeks in anticipation of Food and Drug Administration approval of Ibsrela (tenapanor) in treating irritable bowel syndrome with constipation (IBS-C).
So what
Investors' reaction the day after the FDA approval isn't all that unusual for a small biotech stock. Some opt to take profits off the table after a milestone development.
Now what
While investors watch how Ardelyx's launch of Ibsrela in treating IBS-C goes, the company should have more big news on the way relatively soon. It hopes to file for U.S. approval of the drug in treating hyperphosphatemia next year. If all goes well, the biotech will have two approved indications for Ibsrela by 2021.

What happened
Shares of Ardelyx ( NASDAQ:ARDX) were down 16.8% as of 11:42 a.m. EDT on Wednesday. The drop came after the biotech stock soared Tuesday following its announcement of positive results from a late-stage study evaluating its lead experimental drug candidate, tenapanor.
So what
High volatility comes with the territory when investing in biotech stocks, especially clinical-stage biotechs like Ardelyx. But in many cases, the up-and-down swings don't really mean much. It's nearly always best to focus on the reasons for buying (or not buying) a stock in the first place, and ignore the short-term share price fluctuations.
Now what
While the results from the Amplify study certainly present good news for Ardelyx, the company still has more hurdles to jump. The biotech expects to announce results from its second late-stage study of tenapanor as a monotherapy in the fourth quarter. If those results are also positive, Ardelyx plans to file for U.S.
The company's Japanese partner initiated pivotal late-stage studies of Ardelyx's lead candidate

What happened
Shares of Ardelyx ( NASDAQ:ARDX) were soaring 8.9% as of 2:57 p.m. EDT on Wednesday.
So what
Kyowa Kirin's initiation of multiple phase 3 studies is good news for Ardelyx in a couple of ways. For one thing, it triggered a $5 million milestone payment. More importantly, it gets the two collaboration partners even closer to potential regulatory approval for tenapanor in Japan.
Now what
While the start of Japanese clinical studies is good news for Ardelyx, a more important milestone for the biotech stock is only a couple of weeks away. By April 29, the Food and Drug Administration should announce its approval decision for tenapanor in controlling phosphorus levels in adult patients with chronic kidney disease.
