Yen-Lung Chen

Yen-Lung Chen discloses dealings in Ambarella Inc to SEC (Form 4). Over a trading history stretching from 17 March 2014 to 16 December 2014, the count stands at 5 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The newest entry dates from 18 December 2014: an option exercise, in Ambarella Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
