Pavel, I couldn’t open your file, Archibaldx calculation look decent, thou I do not understand why 2022 SP is lower then 2020.  

 Just quick look at  LAC SP and stochastics- it is obvious that SP got ahead of itself and very much possible that Approval got baked in in a SP.   RCI, MCD etc. – all showing overbought condition. So I do anticipate a pullback to nearest support level , about $16.  Still looking at the current market news about future EV market and how hot this sector is – I would not be surprise  to see LAC bounce back . 

 EV market is hot, a lot of companies SP is high and they are years away from production, be it a car company, or lidar, or battery.  By the time T-P comes on line I see LAC around $30-$35  in three years.
