AMD Stock Upgraded: What You Need to Know

Economist John Maynard Keynes is generally credited with the quote, "When the facts change, I change my mind." Today, it's Merrill Lynch (CAPS rating: 93.93) that is putting the quote into practice.

According to StreetInsider.com, it's been more than two years since Bank of America's Merrill Lynch brokerage unit downgraded semiconductor chipmaker Advanced Micro Devices (NASDAQ: AMD) to underperform, assigning the stock a $4 price target on worries that the perpetually underperforming AMD just couldn't effectively compete with rivals such as Intel (NASDAQ: INTC) and NVIDIA (NASDAQ: NVDA).

Since that rating came out, however, AMD shares have not fallen, but instead climbed to nearly $10 as of this writing. And with this "fact" having changed, Merrill Lynch has decided to change its opinion of AMD stock today -- and upgraded the stock two notches, from underperform to buy.

Here are three things you need to know about that upgrade.

1. Sua culpa

In a rare mea culpa, Merrill Lynch admitted today that it missed out on the turnaround in AMD's business -- and in its stock price earlier this year.

Quoted on TheFly.com this morning, the banker explains that it was "too concerned" about AMD's history of "weak execution, high debt, and competitive risks" from Intel and NVIDIA. In focusing on the company's disappointing history, Merrill says it may have missed the unfolding story of AMD's rising strength in PC gaming, artificial intelligence, and computer deep learning. AMD's progress in these areas, says Merrill, has led to gains in chip market share for AMD.

2. Balance sheet repair

At the same time, Merrill Lynch gives AMD's new CEO Lisa Su credit for shoring up AMD's balance sheet. With nearly $1.3 billion in cash on its books, S&P Global Market Intelligence data show that AMD has grown its cash reserves by roughly 25% since Merrill Lynch first downgraded it back in July of 2014. At the same time, AMD has shrunk its long-term indebtedness to just $1.6 billion.

Result: Cash on hand is nearly sufficient to balance out debt at AMD, and at the same time, says Merrill, AMD has succeeded in refinancing the debt it still carries, pushing out its due date and giving the firm breathing room as it continues to build cash.

3. The upshot

Factoring all these improvements into consideration, Merrill Lynch says that the same AMD stock it previously thought to be worth only $4 is now worth three times more -- $12 a share. And with AMD stock still selling for less than $10 a share today, that means there's more than 20% upside in the stock.

But is Merrill Lynch right about that?

The most important thing: Valuation

That's really hard to say, because while AMD's improvements are obvious, it's still not obvious that AMD stock is a better buy than Intel or NVIDIA, say.

Debt may be down and cash may be up, but S&P Global data show that AMD is still burning cash at the rate of $127 million a year. Under GAAP accounting standards, the stock looks even worse, with net losses of $548 million over the past 12 months. In contrast, both Intel and NVIDIA are GAAP-profitable companies, and both are generating not just positive free cash flow, but free cash flow actually superior to their reported GAAP profits -- $10.6 billion in FCF for Intel, and $1.2 billion for NVIDIA, over the past 12 months.

Long story short: I can't deny that AMD has made improvements in its business. I cannot say that Merrill Lynch is wrong when it peers into the future, sees these improvements continuing, and believes that despite its losses and despite its cash burn, AMD has a bright future ahead of it. All I can do is point to the multiple instances when other analysts have predicted similar turnarounds for AMD -- and been proven wrong.

AMD's financial picture looks a whole lot prettier today than it did just two years ago, but Intel and NVIDIA aren't sitting still, and AMD still has a long way to go to make up the gap between it and its more successful rivals. To cite another famous quote, I'm still not convinced that this leopard has changed its spots.
