Just before Wednesday's opening bell, tech giant Palm (NASDAQ: PALM) announced that it raised the number of shares it will sell in a new public offering. The company will now offer 20 million shares rather than the previously reported 16 million. The offering will be at $16.25 per share and should lead to $313.1 million in proceeds.

In early trading, PALM was up more than 3% -- pushing the stock through the $16 level. This level had acted as resistance in the past, so this technical advance is important. We could see the $16 level act as support if needed. Further support could come from PALM's 10- and 20-week moving averages, both of which are advancing to catch up to the equity's current position. More support can be found in the form of PALM's 10- and 20-month moving averages.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Adobe Systems Inc. (NASDAQ: ADBE) just beat low Q3 earnings estimates but revenue also declined.
• Best Buy Co. Inc. (NYSE: BBY) earnings fell short of estimates but revenue was better than expected.
• Cracker Barrel Old Country Store Inc. (NASDAQ: CBRL) posted better-than-expected Q4 earnings.
• Discover Financial Services (NYSE: DFS) posted a surprise Q3 profit but shares rose slightly on the news.
• Dress Barn Inc. (NASDAQ: DBRN) reported modest growth in both net income and revenue in Q4.
• FedEx Corp. (NYSE: FDX) said that its Q1 earnings and revenue dropped but its cash flow has improved.

For Palm (NASDAQ: PALM), the future is really about one product: the Pre smartphone. And based on the latest quarterly report, it looks like things are going fairly well (the device was launched in June).

In fiscal Q1, Palm sustained a net loss of $161.1 million, or $1.17 per share. However, if you exclude certain items, the result was a loss of $13.6 million, or $0.10. This was much better than the Street's consensus of $0.24.

Memphis-based package delivery giant FedEx Corp. (NYSE: FDX) is generally seen as an indicator of the state of commerce in the U.S. Last week, not only did the Fed's Beige Book report suggest that the economy had stabilized over the summer, with signs of recovery in some districts, But FedEx also boosted its earnings guidance due to stronger-than-expected volume in its international priority-delivery service. So a question going in to FedEx's fiscal first-quarter report this week is whether the company is still a bellwether.

For the three months that ended in August, when FedEx opened distribution hubs in Chicago and Toledo and declared a quarterly dividend, analysts surveyed by Thomson Reuters are looking for it to report that earnings fell 60.2% from a year ago to $0.49 per share. That's also down 23.4% from the previous quarter, as well as less than the recently updated outlook. First quarter revenue is expected to be down 18.3% from a year ago to $8.2 billion.

PALM September option implied volatility is at 81, November call volatility is at 69, puts are at 76; below its six-month average of 81, according to Track Data, suggesting less price movement after EPS.

Apple, Inc. (NASDAQ: AAPL) and Palm, Inc. (NASDAQ: PALM) just keep volleying with each other with the duel between the iPhone and the Palm Pre, don't they? Accusations of an
"iPhone copycat" surfaced right after the Palm Pre was announced. After all, quite a bit of Apple design influence now works at Palm. But the war is not over yet, as one of the neater features of the Palm Pre has now been deactivated by Apple.
