$Novavax(NVAX.US)$ what is causing this huge drop?

$Palantir(PLTR.US)$
27.5 will be a strong resistance, but I have faith it can break it, if that happens, next resistance is 30

$UP Fintech(TIGR.US)$Poor tiger. If you buy this product, you really won't cry until you see the coffin.
Knowing full well that there is a tiger in the mountain, he is partial to the tiger mountain.
