AI Photonics Trader
mkfilko posts on X as “leki” (@mkfilko); no real name, employer or professional background is disclosed. The account publishes company deep dives and technical-analysis threads on small- and micro-cap photonics, optics and semiconductor names listed in the US, UK, Sweden, Germany and Korea — $BRUN, $IQE, $SIVE, $MRLN, $LPK and $DGXX among them — and posts weekly updates on a simulated portfolio alongside trade alerts to subscribers. He pushes back on being labelled a trader: on 31 May 2026 he wrote that “the numerous TA posts I make can somehow flood my page and give the wrong impression that I am a trader.”
