There's never a dull week on Wall Street. Let's go over some of the news that will shape the week to come.

The market kicks off the new trading week just where it left off, with big banks reporting. In case you missed it, the two financial-services juggernauts that reported on Friday morning delivered mixed results. Citigroup (NYSE:C) will try to provide a clearer direction when it offers up its fresh financials, taking the baton -- but running in which direction?

Analysts see Citigroup's revenue and earnings declining slightly in its latest quarter. That doesn't seem like a very good way to run with the baton.

April 15 is Tax Day, and as folks scramble to file their returns our time -- and those due refunds wonder why they took so long -- it will be business as usual in Corporate America. 

Intel (NASDAQ:INTC) reports quarterly results on Tuesday. The chip giant best known for its microprocessors that fueled the PC revolution has had to scramble in an era where smartphones and tablets have grown at the expense of desktops and laptops. Analysts see Intel earning $0.37 a share, just off the $0.40 it posted a year earlier. That would seem to make it a low hurdle to clear, but it's probably not a good sign that Intel has come up short against Wall Street's profit forecasts in three of the past four quarters.

Another tech bellwether steps up on Wednesday, as IBM (NYSE:IBM) reports quarterly results. Intel and IBM used to be interlocked as PC pioneers, but IBM quickly discovered that there's chunkier margins to be had in providing enterprise software, corporate consulting, and other business-based solutions.

It's probably not a good trend to see that IBM -- just like Citigroup on Monday and Intel on Tuesday -- is expected to post lower earnings than it did a year earlier. 

If Intel was the PC chip giant during the computer's heyday, it's safe to say that AMD (NASDAQ:AMD) was its pesky little sister. AMD always seemed to give Intel a good fight for the microprocessor market, but AMD has also had to turn to new areas for growth. 

One area where AMD has thrived is in video game console processors. AMD's handiwork now powers all three major platforms. It has been a Wii U staple for some time, but in November we got the AMD-powered Xbox One and PlayStation 4. 

The country's market exchanges are closed in observance of Good Friday. Given the way the market's been rocked lately, maybe we can call this a good Friday indeed, since the stocks will stay in place for a day. 

That still doesn't mean investors can just ignore Wall Street given the extended weekend. Earnings season will kick in, with hundreds of companies reporting the following week. Get ready.
