Tech Signal Board · Drawdowns
Corrections and deep drawdowns
Names in a 10-20% correction and names more than 20% below their 52-week high, as the scanner classified them at the last close.
The other side of the board: names 10-to-20% off their high and under their 50-day (corrections), and names more than 20% below their high (deep drawdowns). A board that only ever shows winners reads as marketing — this page is the honest half.
Scan of 2026-08-18 · 9 signals in this view · the live board carries the ranked daily cards and the daily archive keeps every previous day.

FAQ
What is the Tech Signal Board?
Our nightly scanner reads every covered name after each close and flags what changed — big moves, trend-condition changes, stretched oscillators, drawdown classifications and analyst moves. The board is the ranked daily surface; these views group the same signals by the question they answer.
What counts as a signal on this page?
This view collects the scanner's in a correction, deep drawdown signals. Each row states the engine's one-line read — what was flagged and why.
How often does this update?
The scanner runs after every US close; this page is rebuilt every market morning from that scan and always shows the date it was built from. The daily archive keeps every previous board day.
Is this investment advice?
No. Closelook publishes an investment research diary, not investment advice. Signals describe what our engine measures in past prices. Past performance may not be an indication of future performance.
