Catalysts

Key term: catalyst

Stocks don't move in big ways for no reason. A stock that jumps or drops sharply in a single session almost always has a catalyst behind it — a specific event that gives buyers and sellers a reason to change their minds about what the company is worth right now.

Catalysts come in two flavors. Scheduled catalysts are events everyone can see coming on a calendar: a quarterly earnings report, a product launch date, a regulatory ruling with a known decision date. Everyone knows it's happening, even if nobody knows the outcome yet. Surprise catalysts arrive with no warning at all — a merger announcement, a sudden executive departure, an unexpected lawsuit or recall.

Most big single-day moves trace back to a nameable event of one of these two kinds. That's genuinely useful to know, because it means a stock's daily behavior is rarely mysterious after the fact — there's almost always something you could point to and say "that's what did it."

This is the whole logic behind how Munymo's daily matchups get built. Each day's pairing is chosen because something — scheduled or surprise — has put one or both companies in a position where today's move is likely to be bigger than an ordinary day. Learning to spot the catalyst is the first step to understanding why a matchup was set up the way it was.

In the daily game

The pairing rationale on every matchup page exists specifically to name the catalyst behind that day's pairing — read it first, before anything else.
