What is the all-time high for Coval?

Excuse me, could you please clarify what the all-time high for Coval is? I'm curious to know if there's been a specific point in time where its value peaked, and if so, what that value was. It would be great if you could provide a brief overview of the factors that may have contributed to such a high, and whether or not the market expects a similar surge in the future.
