- 01 Alta Park Capital is a San Francisco technology hedge fund founded in 2013 by Bijan Modanlou, who previously invested at Cavalry Asset Management and Bowman Capital, with partners Joseph Bou-Saba and Jayaveera Kodali. Its Q1 2026 13F-HR, the quarterly holdings report large investors must file, shows a $642 million U.S. stock portfolio as of March 31.
- 02 The equity portfolio shrank from $831 million in December to $642 million, down 23%, while the holding count fell from 34 to 25 as Alta Park exited 14 names.
- 03 Five stakes hold about 31% of the portfolio: Netflix at $48 million after a 51% increase, Nu Holdings at $44 million, a new Apple stake at $37 million, Applied Materials at $35 million after an 18% trim, and Western Digital at $34 million after a 68% cut.
- 04 The quarter ran one playbook. Cash out of memory and storage (Western Digital down 68%, SanDisk down 74%, Micron sold out), sweep away software and consumer names like AppLovin, DoorDash, and Shopify, and rotate into optical-networking chips, Apple, and a bigger Netflix bet.
- 05 The Q2 2026 13F is due by August 14. It will show whether the retreat from memory and storage chips continued toward full exits and whether the new Apple and rebuilt Netflix stakes kept growing.
How Alta Park Capital Moved Last Quarter
What to watch
1. Alta Park cut Western Digital 68% and SanDisk 74%, sold out of Micron, and reduced chip tester Teradyne 43%. The Q2 filing will show whether Bijan Modanlou is finished taking profits from the memory and storage rally or leaves the group entirely.
2. Apple entered the portfolio as a $37 million new buy while Netflix grew 51% to become the largest holding at $48 million. The next 13F will show whether these megacap bets are core stakes or short-term trades.
3. Lumentum and Coherent arrived as new optical-component stakes and ASML and Broadcom were both added, even as the fund swept out AppLovin, DoorDash, Shopify, and Unity. The Q2 report will show whether the tilt toward AI-networking hardware deepens.
