Reuters Market Eye - Credit Suisse says exit polls out on Monday showing Bharatiya Janata Party and its allies headed for a majority still reveal a "range of high uncertainty."
The investment bank points out that while national totals are within a relatively narrow range, the state numbers that add up to those totals vary "widely."
"This suggest high measurement error margins," Credit Suisse says.
Actual election results will be out on Friday.
