There is no knowing what caused this spike especially with this huge 10 times average volume. An enigma indeed. Myself i had expected a retrace which would be considered a natural phenomenon under the circumstances.
Thank you. As of end trade yesterday, BVXV is my portfolio leader, and as the saying goes: The race is on!
I will not be surprised if a substantial drop in price will occur. At any rate i was not at all tempted to sell (some of it)
