Sometimes even your best performance just isn't good enough.
Samsung is learning that difficult lesson Friday after reporting a record profit that nonetheless fell short of investor expectations.
The South Korea-based smartphone maker reported net profit of 7.8 trillion won ($7 billion) in the second quarter. Even though that figure was a 50% increase over the previous year, it fell short of analyst expectations of 8 trillion won.
Samsung shares declined slightly after the earnings report was released. So far this year, shares have lost 14% of their value.
Investors and analysts remain worried about slowing demand for top-shelf smartphones like the Samsung Galaxy S4. The phone, which competes with Apple's iPhone and HTC's One, has sold well.
But the future profitability of the device remains a question -- and Samsung's legacy businesses in television and electronics production don't appear poised to pick up the slack.
The problem is not unique to Samsung. Apple's ( iPhones have also been selling well, but growth has slowed and investors have punished the stock lately. )
BlackBerry ( has also struggled to gain traction with its new Z10 smartphone, and its stock has plummeted. )
Now that Samsung is mirroring that trend, industry analysts believe that the top tier of the market is becoming saturated.
Apple is rumored to be creating a lower-end version of its smartphone to expand its share and better compete with No. 1 Samsung, whose phones run on the Android operating system from Google.
