"do public holidays create dramatic drops down too?"

Yes - actually they contribute to a context where volume is light and volatility is often extremely high. Expect wide range days on those days.

People with long experience in the market expect high volatility on days affected by public holidays. There's an old truism - the office boy was in charge on such days. And when he went out for lunch, the cleaners were in charge. :)

Good luck
