Interesting raise - both HSI and HSIL are rising at the same time
AAStock HSIL
Why HSI and HSIL are
going up at the same time in the up surge in the afternoon for 3 times?
HSIL is calculated
only by Put option price. It doesn't care about Call options.
Because the
institute investors are taking profit or not convinced of the rise.
So they buy all the
put options to cover the risk, turning point may happen.
