At The Motley Fool, we poke plenty of fun at Wall Street analysts and their endless cycle of upgrades, downgrades, and "initiating coverage at neutral." The pinstripe-and-wingtip crowd is entitled to its opinions, but we have some pretty sharp stock pickers down here on Main Street, too. And we're not always impressed with how Wall Street does its job.

So perhaps we  shouldn't be giving virtual ink to "news" of analyst upgrades and downgrades. And we wouldn't -- if that were all we were doing. Fortunately, in "This Just In," we don't simply tell you what the analysts said. We also show you whether they know what they're talking about.

Today, we'll be taking a look at two or three new tech-recs from Cantor Fitzgerald and then move on to examine some good news for Amylin (Nasdaq: AMLN) shareholders. Let's dive right in.

EMC or NetApp? Heck, buy 'em both!
Coke or Pepsi? Ford or Chevy? The world's full of tough choices, but for Fools in a quandary over where to invest in tech, the folks at investment bank Cantor Fitzgerald have a solution: If two competing stocks are both cheap, just buy them both.

And so it is that this morning we saw Cantor recommending storage-tech experts EMC (NYSE: EMC) and NetApp (Nasdaq: NTAP). With its "high percentage of recurring revenue," "broad product refresh," and "aggressive channel expansion," EMC, says Cantor, is worth $30 a share. Meanwhile, investors are currently expecting "zero growth" out of NetApp this year. Cantor, however, believes that NetApp's new flash storage product could help lift it to $38 within a year or so.

At about 20 times earnings each, but with only mid-teens earnings growth projected over the next five years, neither stock looks terribly attractive on the surface. But if you dig into the companies' cash-flow statements, you'll quickly notice that all's not as it seems here. Pegged for only $2.6 billion in annual "profits," EMC actually generated more than $5.4 billion in free cash flow over the past year. Similarly, NetApp's $605 million in net income pale in comparison with the more than $1 billion in cash profit it generated. At approximately 10 times FCF each, both stocks look eminently buyable at today's prices.

Incidentally, Cantor is also recommending Brocade (Nasdaq: BRCD) this morning, which the analyst expects to benefit from "potentially greater sponsorship from EMC." Cantor continued: "With its stock priced at a mere 5x free cash flow, Brocade may actually be the best bargain of the bunch."

Stay in Amylin! The water's fine (or is it?)
And speaking of bargains, analysts at MKM Partners are wondering whether Amylin Pharma might be worth more than it appears to be. Last we checked, MKM had a neutral rating on this stock and a $22 price target. But with Amylin shares surging more than 100% over the past year, that estimate is looking a bit conservative. Result: MKM upped its price target on the stock to $29 this morning.

Why the sudden change of heart? As StreeetInsider.com explains, new data out of Amylin and partner Alkermes (Nasdaq: ALKS) shows that their Bydureon "once-weekly treatment for type 2 diabetes" has been "associated with clinically significant and sustained improvements in glycemic control" over the treatment period. Some investors are wondering whether this could result in renewed interest, and perhaps a greater buyout offer from Bristol-Myers Squibb.

Let's hope so, because for the time being, neither Amylin nor Alkermes is having much success earning profits on their own. Hip-deep in debt, Amylin's $652 million in trailing revenues generated no profit last year, and analysts foresee further losses through at least fiscal 2014. Alkermes, for its part, is just as unprofitable as Amylin today, while its projected profit next year still has the stock trading for north of 700 times forward earnings. (On the plus side, by taking less risk on this project, Alkermes benefits from carrying a lighter debt load and is burning less cash. That's par for the course for this cautious biotech.)

So the best news for Bydureon backers today? There's more than one way to play this drug. If Amylin scares you, you can always take a look at Alkermes instead.
