Radar

Every weekday after the close, Radar gathers SEC filings, headlines, price moves and value investors' 13F changes for about 150 names: the buy range and on-deck names first, then wonderful (tier A) companies. It judges each item with the event rules in the Rule #1 method. It supplies names and facts, never decisions.

2026-10-09

Booking Holdings (FTC action reported over hotel ads) and Lululemon (new president and product chief) are the buy-range names with business news. The 8 October AI-hardware sell-off (NVMI, MPWR, CLS, EME) was market-wide: it moved price, not value. 13Fs show Buffett adding Alphabet, Li Lu adding PDD and Klarman adding Amazon.
