Experts said that prevailing geopolitical concerns in the wake of recent India-Pakistan military conflicts will be a key factor in the upcoming general elections that may help incumbent NDA government at the Centre. With the Election Commission of India (EC) announcing dates for the much-awaited 2019 general elections, market analysts say a pre-poll rally is likely to continue, citing historical data which suggests a positive trend in the stock market in case the incumbent returns to power.
