I think it's fair to say that there's much trepidation about the earnings season that picks up steam this week. And for better or worse, numbers from the big financials have begun to roll in. Last week we saw profit sink for JPMorgan Chase (NYSE: JPM) and significant losses from Bank of American Corp. (NYSE: BAC), Citigroup Inc. (NYSE: C), and Deutsche Bank (NYSE: DB).

Analysts surveyed by Thomson Reuters expect Bank of New York Mellon Corp. (NYSE: BK) to be among those financials reporting fourth-quarter earnings growth this week. They anticipate that Bank of New York will post a profit of $0.70 per share, compared to $0.67 per share a year ago and $0.72 in the previous quarter. Revenue is expected come to $3.8 billion, about the same as it was a year ago. Bank of New York has fallen short of earnings estimates in two of the past five quarters, by as much as 11.1%. For the full year, analysts are looking for $2.78 per share (+5.8%) on $14.8 billion (+4.2%). The consensus recommendation of analysts is to buy BK, and the long-term EPS growth rate forecast is 10.7%. Shares are 48.7% lower than a year ago. Other financials expected to report quarterly earnings growth this week include SunTrust Banks Inc. (NYSE: STI) and M&T Bank Corp. (NYSE: MTB).

Wall Street's optimism in last week's preview about the earnings of tech stocks wasn't misplaced, as there were many more positive surprises than negative ones among the stocks we looked at. This week will bring plenty more data for investors in and watchers of the sector to mull over. Apple Inc. (NASDAQ: AAPL), AT&T Inc. (NYSE: T), and Microsoft Corp. (NASDAQ: MSFT), for example, are expected by analysts surveyed by Thomson Financial to post modest earnings gains from a year ago, to $1.11 per share (on $8.1 billion in sales), $0.72 per share (on $31.3 billion in sales), and $0.47 per share (on $14.8 billion in sales) respectively. All three of these companies ended the week closer to their 52-week lows than highs, and analysts on average consider them each a buy.

Here's a look at some of the week's biggest expected earnings gainers and decliners in the sector:

TheStreet.com's Jim Cramer says the new rules on short-selling could move us higher on this expiration day.

Today will be a huge test of the new short-selling rules because we are starting from a higher plateau.

The brokers now know that it may not pay to short financials that have no mortgage exposure because they might rid themselves of it, and because they might not be able to get unlimited puts because the brokers won't provide them in fear that they will be caught without a borrow because major institutions are taking their stock out of the stock loan vault.

The specter of a total ban on shorting would make being short totally unpalatable. Make no mistake about it, a total ban on shorting, even a temporary ban on shorting would be horrible and destroy the markets outright. That's right -- destroy them.

I can expect that from this commissioner because he is that bad. (Did McCain just get my vote?) But anyone with any sophistication knows that if you can't short or hedge with shorting, you can't trust a market. It will break both ways, up and down. That has to be taken off the table. Almost all of the unintended consequences wreck whatever "good" it could accomplish.
