After bouts of volatility, Wall Street regained momentum in the past few sessions on optimism over trade talks between the United States and China and signs of stabilization in Turkey.

A pair of billion-dollar deals — PepsiCo’s (PEP - Free Report) purchase of SodaStream International (SODA - Free Report) for $3.2 billion and Tyson Foods’ (TSN - Free Report) purchase of Keystone Foods for $2.16 billion — also instilled confidence in economic expansion.

Surging corporate profits and an improving economy as indicated by bouts of upbeat data are acting as major catalyst for the stock market. Notably, the American economy has been on a solid growth path with GDP growth expanding 4.1% annually in the second quarter, representing the fastest pace of growth in nearly four years. The historic tax cuts, infrastructure investment, higher government spending, deregulation, rising wages and record unemployment are fueling huge growth. Per Trump, “the United States is on track to hit the highest annual growth rate in over 13 years".

Additionally, an impressive labor market, increase in wages, rise in consumer confidence and higher consumer spending are boosting economic activities. A rising rate scenario also signals a strengthening economy, which will spur further growth in the stock market.
