Mumbai, May 30 (IANS): Indian equity indices closed in deep red on Thursday due to profit booking before the Lok Sabha election results.

Among the sector indices, IT, metal, auto, pharma, FMCG and realty index were major losers. Media and Pvt Bank index were major gainers.

Twenty-three out of the 30 Sensex stocks closed in the red.

Vaibhav Vidwani, Research Analyst, Bonanza Portfolio, said: "Ahead of the general election results, which are expected to be announced on June 4, foreign institutional investors (FIIs) and individual traders are net long on index futures. It shows that there is a high possibility that the NDA will succeed."

"Additionally, profit booking is evident in the current market as investors seek to protect themselves against unexpected losses in this highly volatile market," Vidwani added.
