Traders will deal with a trifecta of big market-moving issues in the coming week: pesky oil prices, an earnings blitz and all-important inflation data.

"It's an earnings-driven market," says Larry Wachtel, senior market analyst at Wachovia. "The big question is whether the flow of earnings can rescue the market from the twin dreadnoughts of higher oil and interest rates."

Crude prices are once again flirting with the $70 a barrel mark due to geopolitical tensions over Iran and continuing supply issues. Meanwhile, the yield on the benchmark 10-year Treasury bond pierced 5% last week for the first time in over three years.

The earnings madness begins on Monday, with reports from names such as

Knight-Ridder

(KRI)

and

RSA Security

(RSAS)

.

Inflation Ahead?

Investors will be closely monitoring their favorite tickers next week in order to see how the stocks react to earnings news. Traders will be forced to look at the big picture, however, when potentially market-moving inflation data are released at midweek.

"It's inflation week on Wall Street, and all eyes will be on the inflation barometers," says Rich Yamarone, chief economist at Argus Research. Yamarone expects the major inflation gauges to jump more than expected because of higher gas prices in March.

"If these numbers come in too strong, the end result is going to be a further spooking of the bond market, and long-term yields are going to move much, much higher," says Yamarone.

The March producer price index will be released on Tuesday. The PPI is expected to rise 0.4%, a big turnaround from February's drop of 1.4%. Excluding food and energy prices, the core PPI is expected to rise 0.2%, down from a 0.3% increase the month before.

The

FOMC

minutes from the Fed's March 28 meeting are also set for release Tuesday. Bob Pavlik, chief investment officer for Oaktree Asset Management, believes the minutes will be critical, because the market needs to "get more of a feel for the Ben Bernanke-led Fed."

The March consumer price index arrives Wednesday before the bell. Economists expect the index to increase 0.4%, up from 0.1% growth in February. For the core CPI, the consensus estimate is for a 0.2% increase, up from 0.1% the prior month.

"The Fed's inflationary concerns are obviously real, and even if they decide to stop raising rates, we're still unsure of what the repercussions of cumulative rate hikes will be," says Randy Diamond, sales trader at Miller Tabak. "Furthermore, there will eventually be some reason for the Fed to stop raising rates, so either way, the end result is a weaker economy."

The economic data for the week rounds out on Thursday, with the leading indicators for March and the Philadelphia Fed Index. The Philly Index, which is expected to rise to 14.5 from 12.3 in February, is a monthly survey of manufacturers located in Pennsylvania, New Jersey and Delaware and is considered to be a good indicator of changes in employment, price inflation and conditions within the manufacturing industry.
