Hi everyone
I'm totally new here, just researching this stock for a long term hold (I'm no trader).
The results are great & reading about accelerated growth in 2021 sounds great.
It's a pretty volatile stock, is that due to liquidity issues ?
Big jump today, is this normal, will I be investing on a 30% increase day when many may be taking profits ? (great to invest long term but not when you see a 15% fall the following day)....
Any long termers here that can offer some advice, seems everyone likes the management, is everyone more excited about 2021 than before ?
TIA
