Someone has rightly said, markets are never rational hence smart investors can take advantage of same and make money. I had invested in this stock at 350 levels somewhere in 2023 and within 6-8 months sold at average 800+, still remember sold 1000 quantity at upper ckt above 900 now its available at 180. 
In last 3 years capacity has gone up, sales have tripled and current sales to market cap ratio is 1.5 which is very lucrative, added at 177 level for 2 years. This has potential to become a 4-5X. Not a buying suggestions, all views are personal analysis.
