Biden is limiting batteries from China. MULN has a new battery installation in the US for fabrication. There 3 short terms supports in the following graph if interested, still a risky move with MULN which has been manipulated a lot recently.
It could be interesting in the current context where Biden is limiting Chinese battery components.
MULN is suspiciously oversold and manipulated by shorters. It is arriving at a daily support. A possible bounce, but risky, bounce could be expected at this level.
