India's main stock index surged over 6% today to a record above the key 25,000-point level, as opposition leader Narendra Modi thundered to victory in India's election.
The dramatic victory by Mr Modi and his Bharatiya Janata Party(BJP) was the first time a single party has won a majority inIndia's parliament for three decades.
The Bombay Stock Exchange index, known as the Sensex, gained over 6% in earlier trade as results showed pro-business Modi and the BJP expected to score a huge win after a marathon poll.
The index eventually closed with gains of almost 1%.
Modi has ridden a wave of voter support with his message of jobs, development and revival of an economy that is growing a decade-low levels.
His party ousted the left-leaning Congress party which has ruled India for a decade and dominated the country's politics for most of its post-independence history.
The influential Federation of Indian Chambers of Commerce and Industry (FICCI) called Modi's "decisive mandate" a "positive for India".
"It is amply clear the country, especially the youth, wants development and good governance," said FICCI president Sidharth Birla, adding he hoped Modi's win would restore confidence in India.
Shares in infrastructure and energy companies, particularly of those whose owners are seen as close to the BJP, surged. Adani Enterprises, controlled by stalwart BJP supporter Gautam Adani, rose as much as 17%, while Reliance Industries, which is owned by India's richest man, Mukesh Ambani climbed 8.5%.
Banks were also among top gainers, with Canara Bank and Andhra Bank both gaining 24 percent.
The rupee surged over 1% higher to 58.62 against the dollar, building on gains in recent weeks that have been fuelled by expectations Modi would win the gruelling six-week election and introduce reforms to turn around the economy.
The rupee has now risen 17% since sinking to a record low of 68.85 in August when investors were worried about a fiscal deficit crisis and waning foreign investor confidence as the government struggled to boost growth in the face of global economic turmoil.
Stock markets have risen 5% in the past week alone as heady optimism has returned despite low investment and weak growth, stubbornly high consumer inflation and widespread corruption.
India's economy grew 4.9% in the financial year to March, half its pace during the country's boom years.
