TNPL is at very much discounted price and one should buy in my opinion as it can touch a high of 331 in long term holdings....., it's not a buy or sell recommendation as I am not a sebi registered person and I am just sharing my opinion.
You have bought it at a high price , it is falling first it will go high upto 2508 and then will fall again minimum upto 2030 after that it may go high upto 3445.45 but will take time till then you can hold
