Their picks, scored

Across their last 20 scored bets: 30% hit rate, -2.07% mean alpha, trader score -2.36. Their last-14d mentions, direction-adjusted, have moved -4.4% since posting (mean over 26 mentions with price data).

Holding AI infrastructure core while trimming for cash

BullrunIO is focused on a small AI infrastructure basket, explicitly holding CRDO, ALAB, and MU while keeping CRDO, ALAB, and MRVL on the owned/watch list. The distinctive read is less a fresh fundamental thesis than active cash management: trimming CEVA, NVTS, and MRVL with intent to rebuy on pullbacks. Evidence is concentrated on one June 19 portfolio update, so conviction reads as tactical rather than deeply developed.

Direction this week

The week is dominated by one tactical portfolio update: hold CRDO, ALAB, and MU while trimming CEVA, NVTS, and MRVL to raise cash. Conviction is concentrated in AI infrastructure exposure, but the evidence is thin and clustered on June 19, so single-update pump or portfolio-signaling risk is elevated. No true flip is visible, though MRVL is two-sided because it appears as owned or watched and also trimmed.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
