Jump in shares at the end of trading time

I have observed that in case of kaveri seeds company share. the price was jumped by 4-5 points at 7.31 and ended at 556.60
same case with other shares …

can anyone explain this??

If the share price went up during the end of the trading day, then this means that people expected the stock price to trade at higher levels and this expectation was met by consistently increasing the bid and ask prices towards the end of the trading day. Same case with other stocks as well.
