I looked at GME late last year, just as the share price moved away from me. I was not able to establish a position, but have been keeping an eye on it ever since.
Recently, the stock price fell back to the $20.xx range, and I started writing cash-secured puts, with the intent of establishing a 3-4% position.
Here is a slide-deck, which summarizes my current thoughts (Revisiting GME).
Basically, in the base case, I think the stock is worth somewhere between $25-30. In the worst case, it is worth somewhere around $15, while in the best case, it could be worth nearly twice its current worth. At current prices, it seems like an interesting risk-reward bet.
The stock has declined substantially, has high short interest, is extremely volatile, and pays a fat dividend. The sentiment against retailers is brutal. In short, if we have adequate faith in the valuation, it is an ideal candidate for selling options on.
