US stocks wrapped up the week on a gloomy note, as Wall Street was battered by growing concerns over the US Federal Reserve's latest monetary policy and US-China trade prospects, as well as digested a slew of mixed data that dampened growth potential.

In the week ending Aug. 2, the Dow sharply fell 2.63 percent. The S&P 500 plunged 3.14 percent, marking its worst level since December 2018. The Nasdaq lost 3.98 percent.

This week marked negative trading sessions for the market with a tepid start and a worrying ending, with the three major indexes hitting record lows during the week.

On Friday, the three major indexes ended with marked losses, capping off a tumbling week as market jitters persisted over US-China trade tensions and Fed's unclear stance on future path for easing moves.

The Dow Jones Industrial Average decreased 98.41 points, or 0.37 percent, to 26,485.01. The S&P 500 fell 21.51 points, or 0.73 percent, to 2,932.05. The Nasdaq Composite Index fell 107.05 points, or 1.32 percent, to 8,004.07.

Wall Street has been rocked since Thursday, after US President Donald Trump tweeted that Washington would put more tariffs on Chinese imports, triggering broad fears over the global economy.

In the wake of the Tweets, the majority of the 30 blue-chip stocks in the Dow extended losses around market close on Friday, with shares of Cisco Systems down nearly 3.9 percent, among the worst performers.

Shares of widely-acknowledged trade bellwethers Caterpillar and Intel lost 1.77 percent and 1.66 percent respectively.

Following Trump's announcement, the Cboe Volatility index, widely considered the best fear gauge in the stock market, increased 10.86 percent to 17.87 on Thursday.

Throughout the week, market participants pored through the Fed's latest monetary policy and Fed Chair Jerome Powell's remarks on further rate cuts, which surprised investors and caused significant pullbacks in the three major indexes.

Wednesday was a day for Wall Street to mourn, as the three major indexes posted the steepest daily falls of the week, as Powell noted rate cut was not a start of easing moves, after the central bank announced interest rate cut by a quarter point for the first time in more than a decade.

The Dow Jones Industrial Average closed Wednesday with a plunge of 333.75 points, or 1.23 percent. The S&P 500 slumped 32.80 points, or 1.09 percent. The Nasdaq Composite Index also sharply slid 98.19 points, or 1.19 percent.

The federal funds target range now stands at 2-2.25 percent, which became the first reduced range since December 2008, when rates were reduced close to zero during the global financial crisis.

"As the (Federal Open Market) Committee (FOMC) contemplates the future path of the target range for the federal funds rate, it will continue to monitor the implications of incoming information for the economic outlook and will act as appropriate to sustain the expansion," the FOMC said in a statement.

During an ensuing press conference, Powell said the central bank's cut was a "mid-cycle adjustment to policy," adding that the rate cut is "not the beginning of a long series of rate cuts."

The remarks sent chills down through the market's spine, evaporating all the gains of the three major indexes of the day and sinking the Dow by a tumble of over 470 points once in the afternoon sessions, which marked its worst day since May.

Powell's remarks has sent "a muddled and confusing message on the outlook for the fed funds target rate and one that disappointed market participants hoping for a more clearly dovish signal," according to a Bank of America Merrill Lynch Global Research report on Wednesday.

Meanwhile, Wall Street digested a batch of key economic data this week, some of which came below market expectations and pointed to slowing US economic activity.

On the economic front, US consumer sentiment index registered 98.4 in July, higher than the 98.2 in June, the University of Michigan said on Friday.

However, the reading came below market estimate of 98.5, according to economists polled by financial data provider Refinitiv.

Total nonfarm payroll employment rose by 164,000 in July, and the unemployment rate was unchanged at 3.7 percent, the US Bureau of Labor Statistics reported on Friday.

The job growth came shy of the forecast of 165,000 by economists surveyed by The Wall Street Journal.

July's reading was in line with the average employment growth in the first six months of the year. Yet it was lower than the average monthly pace of 223,000 in 2018.

The Institute for Supply Management (ISM) manufacturing index fell to 51.2 in July from June's 51.7, the lowest reading since August 2016, ISM said on Thursday.

The reading indicated that the US manufacturing sector expanded at its slowest pace over the past three years.

Initial jobless claims, or the number of Americans filing applications for unemployment benefits, rose moderately to 215,000 in the week ending July 27, said the Labor Department on Thursday.

The reading marked an increase of 8,000 from the previous week's level, which was revised up by 1,000 to 207,000.

US private-sector employment increased by 156,000 in July from the previous month, according to the ADP National Employment Report on Wednesday, which topped market estimates of 150,000.

The services sector and goods producers contributed the most to July's growth, which came higher than June's revised increase of 112,000.
