They halt for the day at 7%, which is where US breakers kick in for a break.
It’s funny, I flipped on the stock news and they again are having a cow over the markets being down HUGE numbers, yet it’s a down spike of a mere 2%. Which is normal market volatility.
The media is having fits over hundred point swings, but with the market at 16000-17000, a 100-200 point swing is the historical daily volatility.
