📡 Sectors as a Signal — Where May the Wave Be Forming?

The concept: The market moves in waves — and sectors may tell you where the next one is forming. When multiple penny stocks in the same industry all file 8-Ks in the same week, something may be happening: a possible regulatory shift, an emerging funding trend, a new technology gaining traction. It is not a guarantee — but it is a pattern worth paying attention to.

The logic: Sectors are ranked by recent 8-K filing activity — the most active appear first. A 🔥 amber badge means 3 or more companies in that sector filed an 8-K in the past 7 days. A ● green badge means 1 or 2 did. No badge means the sector has been quiet. Within each sector, companies are sorted by most recent 8-K by default — but you can re-sort by price, volume, or name.

How to use it: Scan the sector rows from top to bottom — the active ones are already at the top. Click any sector row to expand it and see the companies inside. Use the search box above to jump straight to a sector by name. If you get lost or want to start over, hit the ↩ Show All Sectors button to reset.

Sectors with recent 8-K activity appear first — amber badge = high activity — green badge = some activity
