NEW YORK (

TheStreet

) -- Regardless of why a stock is in the news, it never hurts to hear what a professional investor has to say about it. The key is to gather as much information as you can in order to make the most informed investment decisions you can. As Jim Cramer often reminds, investors must do their homework.

So what has Cramer had to say lately about today's headline-makers? At Stockpickr, we've combed through his recent

RealMoney

blog posts, "Mad Money" TV show recaps and "Stop Trading!" segments to find out

what he thinks about some of today's newsworthy stocks

.

AIG

(AIG) - Get Report

: AIG

continues to surge

, lately up another 2%. Meanwhile,

CEO Robert Benmosche

said he could wait up to three years to spin off a couple of foreign units, something the insurer had previously seemed in a hurry to do in order to repay government aid.

In a post yesterday to his

RealMoney blog

, Cramer said he worries less than he used to about the "incessant trading" in stocks such as

CIT

(CIT) - Get Report

,

Fannie Mae

and

Alcatel-Lucent

(ALU)

because "when we used to have rules and government officials that were willing to speak the truth about stocks we wouldn't have these single-digit players out there every day." Without that, though, he said, "is it really uninformed speculation?"

As for AIG, he wrote: "Here's a stock that's doubled, or if you want to think about it presplit it has gone from one to two. Why? Because its CEO, a respected one, Robert Benmosche, basically pledged that the company would pay back all of the money owed the government and be profitable."

AIG closed up $2.39, or 5%, at $50.23 on Friday.

Dell

(DELL) - Get Report

: Dell

earned 24 cents a share

in its second quarter, up from 15 cents in the prior quarter and above analyst expectations.

In a

blog post yesterday

, Cramer wrote: "Dell saying big ramp next year, great for

Hewlett-Packard

(HPQ) - Get Report

too!"

Dell closed up 28 cents, or 1.8%, at $15.93 on Friday.

Tiffany

(TIF) - Get Report

: Tiffany

increased its full-year earnings guidance

to $1.65 to $1.75 a share, from $1.50 to $1.60 a share.

On

Wednesday's "Stop Trading!" segment

, Cramer said there was an "all-at-once retail thing going on," which saw companies such as Tiffany and

Williams Sonoma

(WSM) - Get Report

rising at the same time as companies such as

Dollar Tree

(DLTR) - Get Report

and

Family Dollar

(FDO)

. "Tell me if you really need anything at Williams Sonoma," he said. "That can't be going up if people are in a recession."

Tiffany closed up $3.82, or 11.3%, at $37.57 on Friday.
