Basically the budget reconciles the gap between income & expenditure for the next year. Authorities have to bridge the huge negative gap by introducing reforms mainly for tax system & tight control of import bill to protect currency depreciation & diminishing reserves. Encouraging foreign investors is another strategy.
Such reforms directly impact to business community & consumers as well hurting either party to some extent. It is doubtful budget proposals would bring a quick impact to the stock market but in the midterm. Surely dragging more foreign direct investment would be the steam for capital markets but there lies a hitch in global economic conditions. Additionally, what technical experts produce for the next stage of stock market would be interesting & the accuracy level of such analysis.
