Hey tato,
Sorry, no guesses here on mid- or long-term for either stock.
I don't own SGLS, but if I were to, I'd be trying to figure out how to short it legitimately in the US on any kind of run it may see in the future. Carnes past history points to shorting as a safer bet than thinking long with SGLS.
I have some play money in RVGD. Hopefully they don't try to meet or exceed my LOW expectations.
Regards,
