S-1 is Korea's leading security services company, part-owned by Japan's Secom and affiliated with Samsung, with steady recurring revenue from alarm monitoring and building management and a large market share. It is a stable, cash-generative business, but growth is modest and there is no clear catalyst for a re-rating.

How this is worked out
What it measures: day-to-day price moves over the past year, as a yearly figure, ranked against every stock we cover. Very calm under 20% a year, Calm 20 to 30%, Average 30 to 40%, Bumpy 40 to 55%, Very bumpy above that.
What we found: across about 13,500 stocks in 34 markets (2002 to 2025), past swings were a good guide to the next year's, and bumpier stocks fell further. How much further changed too much between eras to put a number on it.
Calm is not safe: a calm stock can still slide steadily.
