Anytime a penny stock has a great run like this, it's natural for many to bail if there is not a constant stream of news.
Sad for that mentality, a constant stream of news is a sure sign of a pump and dump scam.
So you are seeing that mentality being played out.
No news for 3 days and the original story holders get spooked.
Instead of averaging down, they rather sell for a loss and move on to lose in another.
Seen it, done it myself.
DD is way to strong to get spooked now.
