AltayCap
Value investor, Istanbul. Free writeups
AltayCap is a pseudonymous investor who publishes free write-ups on X and on a Substack of the same name and does not disclose a legal name; the account describes itself as a value investor based in Istanbul. On the publication's About page the author says they are a long-time value investor who founded and later exited a media company in the video-game industry, that they are "not affiliated with any fund," and that they make "my living investing, not writing" — the newsletter exists to "refine and share my own due dilligence." The write-ups concentrate on smaller-cap value and net-net situations in Japan, alongside games, animation and payments companies.
