astec

I bought the ASTEC shares on May 4, 2018 @ 727/-, but this stock has started moving slowly downwards. Should hold this stock in this situation ? I bought this stock for short term. Please suggest.

I have been watching and trading stocks in the stock market for just over an year. But honestly I have never seen anything like the things happening in Astec. I have heard about and seen some operator driven stocks,but Astec seems to be from another planet. The stock hit upper circuit yesterday...
