Fastly opened at 16 and has hovered around 26-28 dollars for a while. Akamai, which I believe cf is closer to in terms of features and overall structure is around 90 a share. At 18-19 a share it seems possible that cf would gain another 10-20 per share from where it's at today.

Obviously this is just projecting. I bought shares on Friday above where it closed and today it's up so far. I think the window is still open but idk how much longer that will be true. Time in market usually beats timing in market though.
