Dipan Mehta discusses the cautious outlook on chemicals, interest in agrochemical plays, auto sector trends, high PE ratios in capital goods, potential investments post-election, mixed earnings season results, and concerns about overvalued EMS companies. Mehta also says: "If the government comes back with a stable majority, then the best stocks to buy would be the defence stocks, PSUs. It could be PSU banks or the PSU engineering companies."
