i watched VKTX presentation at JPM18 and bought a small position of 10K at 4.5. my impression from the presentation is that they were planning to dilute if/when positive data update in 2Q18 allow them to do so at a good price.
but i guess they changed their mind after seeing how strong pps has been lately. why not ? strike it while it's hot and it has been hot alright , lol.
