Unionbank share

Hello,

I bought 100 shares of Union Bank @ 152.90 on 26th and today it reached 153+ but then suddenly it went down to 141. Does someone know why this happened and what should I do ? Should i hold or sell ?

Thanks.

Hold !
Its around its 50 DMA i.e. 157 and has strong resistance there.
So wait for a while and you will get resonable profits in medium term.
