VUL

 When you read this article, CSL has gone up 20X in 20 years and used to be a small company.

However, VUL has gone up 24X in under a year.  And expected to go higher!  This is pure luck but whether it will go higher or crash, I have no means of prediction.  However, I will enjoy the ride and sell some when it reaches the forecast valuation.
