Things never get dull for the country's lone satellite-radio provider. Shares of Sirius XM Radio (NASDAQ:SIRI) moved lower on the week, slipping 0.6% to close at $3.14. Pi! The slight decline contrasted the Nasdaq Composite's healthy 2.4% advance.

There was more going on beyond the share-price gyrations, though. Sirius XM is gearing up for its first quarter earnings report. On the streaming front, Pandora (NYSE:P)received some another analyst upgrade.

Let's take a closer look.

I'm earning for you
It's earnings season, and Sirius XM will be reporting its first-quarter financials on Thursday morning. Wall Street's holding out for a profit of $0.02 a share -- in line with last year's per-share figure -- with revenue climbing 11% to hit $994.6 million. 

Sirius XM topped the milestone of $1 billion in quarterly revenue during the final period of 2013, but analysts see a slight sequential dip this time around. That may seem like an ominous forecast given the steady nature of the historical growth of Sirius XM's self-pay subscribers, but keep in mind that the media giant has a pretty good track record of exceeding Wall Street's conservative expectations.

It will also be interesting to see if Sirius XM revises its guidance. It provides an outlook for its subscriber base, revenue, and free cash flow, and it has often boosted at least some components of that guidance. Either way, this past week has been quiet on the news front outside of programming-related press releases. The week ahead promises to be for more insightful and significant.

Pandora rocks
Pandora is one of many of last year's market darlings to have corrected sharply in recent weeks. The stock nearly tripled in 2013, and even though it's sporting a small gain so far this year, investors have seen the stock surrender a third of its value since peaking just above $40 last month.

Some analysts feel that the correction presents a buying opportunity. A week earlier we had Wedbush's David Pachter upgrading Pandora from "neutral" to "outperform" with a $35 price target. This past week we saw Maxim Group boost its rating on the stock.

Maxim's move -- going from "hold" to "buy" -- on Tuesday also sticks to Pachter's price target of $35. This illustrates how the upgrades are all based on the stock's recent correction. Obviously these wouldn't be bullish calls with price targets of $35 if the stock was at $40 the way it was briefly in March. That's a point worth noting, but in the end an analyst upgrade is clearly a positive development.
