i don't think it is meaningful to us because April 14 is the rollover to the May 19 contract and is not an actual daily/premarket change for the $vix volatility index. The 14.78 is for the VIX future contract not the volatility index. The April futures contract expired and a new contract is beginning. At least that is my understanding of how the futures rollover contract works. Do your own dd as I have been wrong before. IMO it is comparable to the difference in gold spot price and gold futures prices when the futures price rolls over.
