KRRO shares took a nosedive today—here's why traders are hitting the sell button.

Market jitters or company-specific woes? Biotech stocks are volatile by nature, but Korro Bio's sudden dip raises eyebrows. No major news from the company, yet the tape tells a different story.

Short sellers circling? With speculative biotech plays, downward pressure often comes from bears betting against shaky fundamentals. Or maybe it's just another case of 'buy the rumor, sell the news'—except there wasn't even any news.

Silver lining for crypto degens? At least this isn't another -80% altcoin dump. Though if you're holding KRRO today, that's cold comfort.

The big news here is that the study failed to meet its primary endpoint. As a result, Korro Bio has announced that there are no plans to complete additional SAD patient cohorts for KRRO-110. It has also shifted focus to KRRO-121 as its next development candidate. This is a treatment designed for patients with hyperammonemia, a condition in which there are excessive amounts of ammonia in the blood.

To go along with the failed clinical trial, Korro Bio announced major changes to its workforce. The company will cut 34% of jobs and suffer a one-time charge of $2.4 million. It has also announced the resignation of Chief Medical Officer Dr. Kemi Olugemo. These changes have extended the company’s cash runway into the second half of 2027, which will allow it to provide clinical data from KRRO-121.
