Investors are looking for any sign that the Republicans are able to govern and, for some reason, have made the health bill a litmus test for all future gains.  Thus, whenever there is a Republican defeat, investors sell.  When the announcement came down that the vote would be delayed until after the holiday, the Dow dropped 130 points, but did recover by end to close down 99.  It doesn’t really make a lot of sense why the failure of an unpopular bill would prevent the success of a popular bill like tax reform.  But that’s the thinking.  It wasn’t just the delay though.  Tech took another drubbing today with Google getting a gigantic fine from the EU.  And there was even good news.  Consumer confidence rose and Fed Chair Yellen opined that, due to the lessons learns from the Great Recession, there would be no other major econ crises in her lifetime.  (Here’s to your health, Janet, and a good long life!)  Volume was right around the 7 billion mark, in line with recent averages.

Wall St. falters as Senate delays health vote

By Lewis Krauskopf

DJ: 21,310.66  -98.89     NAS: 6,146.62  -100.53     S&P: 2,419.38  -19.69      6/27

(Reuters)  The tech-heavy Nasdaq led a broad Wall Street decline on Tuesday with stocks falling more sharply after a healthcare bill was delayed in the U.S. Senate, raising fresh questions about President Trump's domestic agenda.  The benchmark S&P 500 posted its biggest one-day drop in about six weeks and closed at its lowest point since May 31.

Major indexes extended losses after U.S. Senate Republican leader Mitch McConnell decided to put off a planned vote on a bill to dismantle the Affordable Care Act until after the Senate's July 4 recess.

The healthcare legislation, which has encountered resistance from several Republicans, is the first plank of Trump's domestic policy agenda, with investors eager for him to move onto his other plans including tax cuts, infrastructure spending and deregulation.

Promises for such domestic polices helped fuel a 13.1-percent rise for the benchmark S&P 500 since Trump's Nov. 8 election.

“The market likes certainty, and now there’s uncertainty," said Peter Costa, president of trading firm Empire Executions in New York. "What is this going to look like when this gets out of the next iteration? That uncertainty I think is just having people pause a little bit."

"I also think that when the market gets to certain levels, any type of uncertainty, especially in anything that has to do with the administration, will have an adverse effect," Costa said.

The Dow Jones Industrial Average .DJI fell 98.89 points, or 0.46 percent, to 21,310.66, the S&P 500 .SPX lost 19.69 points, or 0.81 percent, to 2,419.38 and the Nasdaq Composite .IXIC dropped 100.53 points, or 1.61 percent, to 6,146.62.

Big tech names weighed most heavily on the S&P 500. Google parent Alphabet (GOOGL.O) fell 2.5 percent after EU antitrust regulators hit the tech giant with a record $2.7-billion fine.

The Nasdaq had its worst day since a tech-led slide on June 9 raised questions about the sector.

On Tuesday, the tech sector .SPLRCT pulled back 1.7 percent. It remains the best-performing major group this year.

"There is some thinking that they ran up too quickly, and if there’s an excuse to sell then we get some traders come in and sell into that weakness," said Bucky Hellwig, senior vice president at BB&T Wealth Management in Birmingham, Alabama.

The healthcare sector .SPXHC weakened after news of the vote delay, and ended down 0.9 percent.

Financials .SPSY were the only sector to end in positive territory, rising 0.5 percent.

Data showed consumer confidence for June rose more than expected, which could bolster the Fed's case for another rate hike this year.

Philadelphia Fed President Patrick Harker said the Fed rightly plans to raise rates once more this year, given recent inflation weakness is likely temporary.

U.S. Federal Reserve Chair Janet Yellen said she does not believe there will be another financial crisis for at least as long as she lives, thanks largely to reforms of the banking system since the 2007-09 crash.

Investors are gearing up for second-quarter corporate earnings season after a strong first quarter, with the S&P 500 trading at nearly 18 times forward earnings estimates, well above its long-term average of 15 times.

"On an earnings basis, the market appears to be fully valued and we need to see fiscal policy, tax and regulatory reform, to drive GDP growth and then stock prices," said Ernie Cecilia, chief investment officer of Bryn Mawr Trust in Bryn Mawr, Pennsylvania.

Declining issues outnumbered advancing ones on the NYSE by a 1.89-to-1 ratio; on Nasdaq, a 1.98-to-1 ratio favored decliners. 

Note:  No volume data published to day but, per BATS, volume was 7.03 billion.
