Why Isn't Micron's Stock Taking Off After Reporting Strong Q4 Numbers?

Micron Technology (NASDAQ:MU) released its latest earnings numbers last week, which yet again showed impressive growth on both its top and bottom lines.

But despite the seemingly strong results, the stock hasn't been taking off in value. Is this a sign that these types of results are already baked into the share price, and that Micron's stock may be approaching a peak, or could there be other concerns weighing on investors' minds?

Micron posted a beat-and-raise quarter

For Micron's most recent quarter, which ended on Sept. 3, the company's revenue came in at $54.2 billion, which was nearly five times the $11.32 billion it reported in the same period a year ago. Significant growth, however, is to be expected these days from the business. What matters is whether it beats expectations, which it did; analysts were expecting a little under $51.1 billion. Micron also beat expectations on the bottom line, and its guidance for the current quarter was also better than Wall Street expectations.

The big unknown weighing on the tech stock, however, is how long the current memory shortage will last. While there have been reports that it may not end for at least a couple of years, there is also no shortage of skeptics. Acer CEO Jason Chen has gone so far as to question if there is even a shortage to begin with, given that Chinese companies are ramping up production capacity. Chen believes that companies are simply trying to protect margins. And it's these concerns that may very well be weighing on Micron's stock these days, preventing it from going a whole lot higher.

Why Micron's stock may not be as cheap as it looks

Many investors may point to Micron's low earnings multiple as proof that the stock still has plenty of upside, as it's trading at a forward price-to-earnings multiple of only seven. That's based on analyst expectations of how profitable it will be in the year ahead.

The problem, however, is that it's based on assumptions and forecasts, which can change due to market conditions. And two or three years from now, the forecast may not be as promising. Once the shortage ends, prices may fall sharply.

There's a fair bit of hesitance around Micron's stock, despite the terrific numbers it posted recently. The reality is that this is a riskier and more expensive stock than it may appear to be at first glance. Forward-looking investors will look for early signs to sell the stock before the good times end, which is why the stock's gains depend more on the outlook for the memory market than on the company's earnings numbers.
