Oklo Inc. (OKLO) shares fell significantly during trading on March 5, 2026. The company issued no new press releases or operational updates to account for the downward movement.
ARK Investment Management LLC reduced its stake in Oklo by 17.7%, according to a recent 13F filing. This filing reflects a position change from a previous quarter.
CEO Jacob DeWitte and COO Caroline Cochran each sold 200,000 shares on March 2. These sales were disclosed in filings on March 4. Both executives executed the trades under a pre-arranged Rule 10b5-1 trading plan established in March 2025.
Negative sentiment followed the combined news of insider sales and the reduction in ARK’s position. The stock price movement appears to be a direct reaction to these regulatory filings rather than broader market trends.
