S&P, Dow set for worst day in eight months on Trump turmoil | Reuters

The S&P 500 and the Dow were headed for their worst day in more than eight months as reports of a leaked memo by former FBI chief James Comey spooked investors, raising questions about whether President Donald Trump tried to interfere with a federal investigation.

Trump asked Comey to end a probe into former National Security Adviser Michael Flynn’s ties with Russia, according to the reports.

The news comes on the heels of a tumultuous week at the White House when Trump unexpectedly fired Comey and then disclosed classified information to Russia’s foreign minister about a planned Islamic State operation.

The latest developments cast a shadow over Trump’s proposed business-friendly policies such as tax cuts and simpler bank regulations, which have underpinned a record-setting rally on Wall Street.

“I think the biggest issue right now is what does this mean for the plan that we thought we were on,” said Jeremy Bryan portfolio manager at Gradient Investments in Arden Hills, Minnesota. “Is it delayed or is it dead?”

Bank stocks, which outperformed in the post-election rally, were the worst hit. The S&P 500 financial sector .SPSY tumbled more than 2 percent, led by losses in Bank of America (BAC.N) and JPMorgan (JPM.N).

Goldman Sachs (GS.N) was the biggest drag on the Dow.

Both the Dow and the S&P 500 fell below their 50-day moving average for first time since late April.

At 10:46 a.m. ET, the Dow Jones Industrial Average .DJI was down 234.47 points, or 1.12 percent, at 20,745.28, the S&P 500 .SPX was down 24.18 points, or 1.01 percent, at 2,376.49 and the Nasdaq Composite index .IXIC was down 83.65 points, or 1.36 percent, at 6,086.22.

The dollar index .DXY sank on Wednesday, erasing all of the gains inspired by Trump’s pro-growth stance after his November election victory. The euro EUR= hit its highest level since Nov. 7, while prices of gold hit a one-month high.

The VIX .VIX, Wall Street’s “fear gauge”, shot up to 12.8 points and was on track for its biggest one-day percentage increase since August.

“We’re largely through the earnings season, so political uncertainty is probably going to be the largest source of risk in the next three to six months.” Bryan said.

Nine of the 11 major S&P 500 sectors were lower.

Utilities .SPLRCU and real estate .SPLRCR sectors – preferred investment options in times of uncertainty due to their slow but predictable growth – were the only gainers.

Target (TGT.N) was up 2.8 percent at $56.06 after the big-box retailer reported a smaller-than-expected drop in comparable sales.

AbbVie (ABBV.N) slipped 2.4 percent to $65.25 after Coherus BioSciences (CHRS.O) received a favorable patent ruling against AbbVie’s Humira drug. Coherus shares rose nearly 7 percent to $23.55.

Declining issues outnumbered advancers on the NYSE by 2,211 to 624. On the Nasdaq, 2,249 issues fell and 433 advanced.

The S&P 500 index showed five new 52-week highs and 17 new lows, while the Nasdaq recorded 18 new highs and 52 new lows.
