Best Buy (NYSE:BBY) rose as much as 6% during Wednesday's trading after analysts at Jefferies upgraded the stock to "Buy," and raised the firm's price target from $13 to $24.

However, with shares of the electronics specialist up 60% so far in 2013, is it time to take some profits?

The good
Best Buy's fourth quarter fiscal 2013 results, announced last week, were certainly better than expected. On an adjusted basis, the company reported quarterly earnings per share of $1.64, versus analysts' consensus estimates which called for $1.53. Revenue for the quarter also beat analysts' expectations after squeaking out growth of 0.2%, to $16.71 billion.

As a result, adjusted free cash flow of $965 million came in on the high side of Best Buy's previous guidance, which called for free cash flow between $850 million and $1.05 billion.

In addition, as Jefferies noted, Best Buy is showing notable progress after its recent management shakeup brought in new blood with "experience in turnarounds and growth of both physical and online businesses" -- a reference to CEO Hubert Joly's previous experience in helping save the sinking ships of Vivendi's video game business unit, privately owned consulting firm McKinsey & Co., and French-based Electronic Data Systems (now part of Hewlett-Packard).

As it stands, investors are reassured that Joly has outlined a tangible turnaround plan, which seems to be bearing fruit. This is more than other plunging retailers like J.C. Penney (NYSE:JCP) can say -- for the time being, anyway. Still, Best Buy undoubtedly has plenty of work to do before it's truly out of the woods.

As an aside, on the heels of J.C. Penney's wretched quarterly earnings, does anyone else find it ironic that J.C. Penney's stock skyrocketed more than 17% the day it chose turnaround specialist and former Apple exec Ron Johnson as its CEO? Poor Best Buy, on the other hand, fell 10% the day it tapped Joly as its new CEO.

Now, however, while expectations have remained undoubtedly low regarding Best Buy's ability to successfully compete against retail's long-term oriented, 800-pound digital gorilla, Amazon.com, (NASDAQ:AMZN) the stock's 60% jump in the past two months alone shows that investors are clinging to the hope that all isn't lost quite yet. Even after the rally, shares of Best Buy are still down more than 20% over the past year, so they could have even more room to run should the company continue to show progress in stabilizing its operations. 

The bad
With this in mind, by opting not to provide fiscal 2014 guidance, Best Buy's management sure isn't giving investors much to help predict when that stabilization might actually occur. However, CFO Sharon McCollam was quick to warn investors that the company expects its "first quarter to be under significant pressure."

Why? In addition to the fact that pre-Super Bowl television sales were shifted into its fourth quarter results, Best Buy will surely suffer from the impact of its recently launched online price match program, with which it hopes to prevent consumers from "showrooming" -- that is, stepping into a physical Best Buy location only to get a first-hand peek of the products that they intend to purchase at a cheaper price online.

So, what's the problem with this mentality? Best Buy's behemoth brick-and-mortar operations, while steadily shrinking, still represent a significant overhead disadvantage when compared to online-only competitors like Amazon.com, and its near-fanatical focus on streamlining operations, all in the name of offering lower prices to consumers.

Without the burden of physical stores to maintain, Amazon is free to focus more energy on forward-looking initiatives like bolstering its world-class website, and building new strategic warehouse locations to improve delivery times. In addition, Amazon isn't afraid of making acquisitions of complementary cutting-edge companies, including its $775 million purchase early last year of Kiva Systems for its orange swarm of warehouse-optimizing robots. Given Amazon's edge, one can't help but wonder how long Best Buy will be able to stand the pressure of promising to match online prices before it has to renege.

Unfortunately, Best Buy's comparable store sales aren't looking great, either. While domestic comparable sales managed to grow 0.9% (coinciding with a 10 basis point decline in gross profits), part of those increases were the result of the aforementioned shift in pre-Super Bowl television sales. In addition, while comps in Europe also grew, total international comparable sales fell 6.6%, largely thanks to double-digit comp declines in Canada and China.

The unknown
Even so, Best Buy's stock remains on a tear, with hopes that the company can once again exceed expectations in the coming quarters. While the stock may have some upside left, playing short-term fluctuations isn't exactly the most Foolish thing to do. Considering management's comments for the coming quarter, then, I won't be willing to buy shares of Best Buy until it can prove it has what it takes to not just survive, but also thrive over the long haul.
