This happens from time to time. You will find companies greatly overvalued sometimes and undervalued at other times. Markets run on emotions in the short term. In the long term, however, markets generally can be much more predictable.
This is how money is made by fundamental investors. If you think this is a no-brainer and this company is highly undervalued, invest in it. Take as much a bet size as your conviction allows. If you are right, you will be rewarded handsomely in the long run.
As per my personal viewpoint, I have a decent sized position at ~360 levels. I don’t feel comfortable right now, I will add more if it falls by another 10% or so.
