After bad earnings tomorrow, this will gap down to the teens or lower. Eventually this could go to $4 a share. Remember all the high flyers from years ago that just kep falling and falling.
It seems you are so sure that there will be bad earnings. Who told you? In a previous comment you mentioned a share price of $4. What is your analysis? Can it be $8 or $1? Or perhaps less than zero, i.e., the company give every investor money to buy shares?
I just went on the SPWR website and there is no news about an earning report tomorrow. Hence you either:
1. been informed by the archangel Michael while you were asleep or by a messenger of any other religion
2. You are an insider knowing what is still a secret. In this case the management must be informed about your indiscretion.
3. You are a loudmouth and liar.
It is too bad that you did not show us your detailed analysis, only giving us your result of $4. I think you made a slight error. It should read -4$ and not +4$. In other words, if you accept a share for nothing you get 4 Dollars from the company.
