Yes buying puts or selling calls is an alternative but you pay a premium with options and they have a high volatiliy premium priced in. I prefer pur shorting versus trying to simulate the trade with options. But, I may have to give up and use options instead as you suggest...
At the open, sell in the money calls. You can sell as many as you like, up to 1000 contracts. Thats 100K short shares, or over 1 million dollars of shortable stock. Best luck! This little pop will ensure the insiders sell every share they have.
Yes sometimes better lucky than good. I am now so glad I couldn't find any shares to short today :)
I really dodged a bullet.
Congrats to longs. Looks like a nice bounce for you tomorrow. I still will be looking to short (now at a higher price) because long-term GRPN business model is not sustainable. Too easy to copy what they do.
