As per my analysis, 81 is the best buy level for NSE:NACLIND with stop loss of only 78 (-3 points risk). My expected upside target would be 85 (+04), 89(+08) & 92 (+11). It may take 6-8 weeks to get above targets.
Note: This is my personal analysis, only to learn stock market behavior. Thanks.
NACL ( NATIONAL ALUMINIUM ) is in uptrend so you can go for long and the expected target price will be 90.
