Ever Seen "Stock Hits Upper Circuit"? Here's What That Actually Means.

You've probably seen headlines like "stock hits upper circuit" or "locked in lower circuit." Sounds technical, but the idea is simple. A circuit is basically a safety brake. Exchanges cap how much a stock can move in a single day, say 5%, 10%, or 20%. Hit the upper limit, and trading freezes there for the rest of the day, since no one can buy it higher. Hit the lower limit, same thing in reverse. Why does this exist? To stop panic-driven chaos. Without it, a rumor or bad headline could crash a stock 50% in minutes with no pause to actually process what's happening. Circuits force a cooling-off period instead. Here's the part that trips people up. Hitting an upper circuit isn't automatically good news, and a lower circuit isn't automatically a disaster. A stock like $TMPV could theoretically hit its upper circuit purely on hype, with no real news behind it, then reverse hard the next day once trading reopens freely. The takeaway. Circuits are a safety mechanism, not a quality signal. Before reacting to one, ask why, not just how much.
