The SP has moved up at least 10% per day in the last week or so... no surprise to see it pull back 10%, and it's holding well at the moment... no one really knows whats going on to be honest. If you truly believe in the growth prospects of iot i wouldnt worry.
I'm glad its down because i don't want the SP to get ahead of itself... and looking for another opportunity to buy in again at a lower price
