NEW YORK, Nov 8 (Reuters) - Investors will focus in the

coming week on whether inflation trends can help sustain the

record-breaking stock rally that has received a boost from

Donald Trump's victory in the U.S. presidential race.

The benchmark S&P 500 surged to an all-time high and

hit the 6,000 level for the first time on Friday, as

expectations of tax cuts and looser regulations under Trump

helped lift the appetite for equities.

A reassuring economic outlook from the Federal Reserve,

which delivered a widely expected 25 basis point rate cut on

Thursday, also helped boost sentiment. The central bank's

ability to keep cutting rates, however, will be tested by

whether incoming data shows inflation continuing to moderate.

The Nov. 13 consumer price index report needs to "confirm

that notion that inflation continues to head in the right

direction," said Art Hogan, chief market strategist at B Riley

Wealth.

Investors believe Trump's proposals, in particular higher

tariffs, could push up consumer prices. Meanwhile, U.S. data has

been stronger than expected, with a recent report showing the

economy grew at a solid 2.8% pace in the third quarter.

CPI for October is expected to come in at an annual pace of

2.6%, according to economists polled by Reuters. That would be a

slight uptick from the 2.4% pace in September, which was the

smallest gain since 2021, but well below the four-decade highs

reached in 2022 that led the Fed to hike interest rates.

More robust inflation could further alter projections for

the Fed's rate-cutting path, after expectations changed with

Trump's election victory. Fed funds futures show investors are

now expecting rates to decline to about 3.7% by the end of 2025

from the current 4.5%-4.75% range, about 100 basis points above

estimates in September.

Expectations of financial easing have helped boost stocks

this year, along with solid corporate profits and excitement

over the business potential of artificial intelligence.

Michael Reynolds, vice president of investment strategy at

Glenmede, said the neutral level for the Fed funds rate was

about 3%, "and we ultimately expect the Fed to stop short of

neutral."

"We ultimately think that they do take that shallow path

because inflation is still a risk," Reynolds said. "We just got

through a period of well-above average inflation. Historically,

that's come in waves."

Adding to that risk is Trump's economic agenda that could

juice inflation along with growth during his presidency.

"We're a long way from knowing specifics around either tax

policy or trade policy, but those are both on the table and will

undoubtedly weigh into the Fed's calculus as they look ahead

from here," said Jim Baird, chief investment officer with Plante

Moran Financial Advisors.

Investors also are continuing to adjust to the new political

landscape, after big moves this week in the stock market's

so-called "Trump trades." The small-cap Russell 2000 was

up 8% on the week, with smaller, domestically focused companies

expected to benefit from Trump's plans to increase tariffs on

imports.

The S&P 500 banks index was up about 7% with

lenders poised to benefit from the Republican's expected efforts

to slash regulations.

The initial market reactions will be tested as Trump fleshes

out his policy aims and starts to name political appointments.

"Markets have started to digest Trump's victory," analysts

at UBS Global Wealth Management said in a Thursday note. "As

more detailed policy proposals emerge from the Trump transition

team, investors should brace for further swings ahead."
