Seismograph Board

Every dot is a company. Its horizontal position is today's price move divided by that name's own daily volatility, so a +2% day for a sleepy utility sits far to the right while the same move for a chip name barely registers. Sector sets the color; the display is winsorized at ±4σ. A description of how far each name moved relative to its typical day, not a signal and not investment advice.
