Andrew Lo: trading record in brief

This profile gathers the share dealings of Andrew Lo across 6 companies, led by Urovant Sciences Ltd., BridgeBio Pharma, Inc. and Sio Gene Therapies Inc. Over a trading history stretching from 2 April 2018 to 22 June 2026, the count stands at 43 filings.

In open-market terms, that means 35 purchases worth €109.7M on one side and 5 sales worth €8.9M on the other. Purchases outweigh sales by €100.9M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 3 share grants.

Half of the purchases are above €50k and half below. Clusters matter here: 34 out of 34 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

On 24 June 2026 came the latest disclosure, a share grant in BridgeBio Pharma, Inc. The clock since the last published purchase (3 January 2022) now reads 1,771 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
