"that's not how this company trades. It sells off right after positive news."
Then you write:
"All I want is a positive announcement on Monday and then to get out. I will jump back in another day."
Aren't you doing exactly what you complain about?
I agree with several others here; trading is fine...but keep a core investment. News happens fast with HDY and the volatility you mention can drive the price up very quickly. Best not to get caught with zero shares! JMO!
