Looks like a concerted effort to give negative ratings on most positive postings without any content as to why in followup messages. Some jerks have more time on their hands than brain power and fool no one.
may need to change you name to chicken little if tomorrow the sell volume is as weak as the after market. a lot of sub 20 share retail traders are doing the selling.

they have just about run out of shares to short. The expectation is that the price will turn down once the hype dies down. I hope they are wrong as this is likely to turn into a pandemic which will not let the interest in Inovio to slacken.
