When Prime Minister Narendra Modi was re-elected in May with a sweeping majority, Indian stock markets jumped to all-time highs as investors anticipated big bang pro-business reforms to revive a flagging economy.

But sentiment is souring in the country's boardrooms after a much-anticipated budget in July failed to provide any stimulus, and instead hiked taxes on the ultrarich and on foreign portfolio investors.

Several businessmen say Modi's government needs to take swift action on the economy, but instead it seems preoccupied with the situation in Kashmir, which is under a lockdown after authorities curtailed the autonomy of the restive region.
