Samsung shares have fallen more than 3% on Tuesday - even after the South Korean electronics giant said it expected another quarter of record profits.
The company, responsible for some of the world's best-selling consumer electronics, including smartphones and tablets, forecast a 63% jump in fourth-quarter operating profit as it also continues to ride the wave of soaring demand for memory chips.
Samsung's trading update comes at a time, however, when many investors have started to have some concerns about the semiconductor industry.
Not only have revelations about security faults on chips throughout the industry caused concerns in recent weeks, there are growing fears that the economic cycle in the memory chip industry faces a downturn.
Late last year, Morgan Stanley suggested the industry would reach a peak in demand this year, just as producers have ramped up production to meet demand.
Meanwhile, market expectations have become so lofty, that even another quarter of record profits fails to impress investors.
Samsung expects a 63.8% rise in October-December profits to Won15.1tn ($14.1bn). Consensus estimates from analysts polled by Reuters put the figure closer to Won15.9tn.
Investors shrugged and sold down the stock 3.11% to Won2,520,000.
