— Why it moved
Why SELX Stock Doubled and Faded Today — June 3, 2026
No news and a pending Nasdaq delisting didn't stop this Taiwan LiDAR name from doubling premarket on 1,300x volume — Stock Pulse flagged it at $0.597 at 7:37 AM, it topped one minute later, and it faded for the rest of the day.
What moved SELX stock
Semilux designs LiDAR optics out of Taiwan. Nothing moved it — no filing, no press release, no coverage; the only company news anywhere near the date was a Nasdaq staff determination from mid-May saying the exchange intends to delist the stock. It doubled on air, overnight momentum doing all the work before most people were awake.
The mechanics
A 17.4M-share float and a $0.28 stock on a company valued around $12M. Roughly 182M shares traded against a 30-day average of about 135K — over a thousand times normal turnover.
SELX by the numbers
The alert window
Stock Pulse alerted at 7:37 AM at $0.597, already up 110% from Tuesday's close. The peak $0.65 printed at 7:38 AM — one minute of window, worth 8.9%. Effectively nothing to catch.
How SELX's move ended
From that one-minute top it bled for twelve straight hours. Regular hours never saw $0.60 again, and it closed at $0.4641, 22% below the alert — anyone in after 7:38 was underwater by the bell and stayed there. Underneath sat no news, a live delisting fight, and a sub-$1 share price.
The tell: when a stock has already doubled overnight on zero news, the alert is catching the exhaustion print, not the start — the premarket was the move, and the day session just unwound it.
