description: "$Eoptolink(300502.SZ) is the cheapest optical module stock, with a forward PE of less than 10. Its technical strength is not inferior to InnoLight, and its net profit margin is even higher. Its performance is 90% of InnoLight's, but its market cap is only 60% of InnoLight's. It can only be blamed on the boss being too low-key and not good at IR. Just hold on, reaching a trillion is just a matter of time."
