Braving all evils of emerging market and trade war fears, the S&P 500 index is on track to record the longest bull run in history. The benchmark is now up for 3,452 days and Aug 22 will mark 3,453 days since the S&P 500 hit its low of 666 on Mar 9, 2009. Since then, the index has risen more than 300% and is up more than 7% so far this year.

The latest rally was driven by strong earnings, booming economic growth and optimism over trade talks between the United States and China. Per Trump, “the United States is on track to hit the highest annual growth rate in over 13 years.” The U.S. economy has been witnessing the fastest pace of growth in nearly four years thanks to the historic tax cuts, infrastructure investment, higher government spending, deregulation, rising wages, record unemployment, rising consumer confidence and higher spending. A rising rate scenario also signals strengthening the economy, which is spurring growth in the stock market.

The wave of mergers and acquisitions also added to the strength. Additionally, the global economy continues to expand at a steady pace despite turmoil in some emerging markets like Turkey and Venezuela.
