Shares of consumer electronics giant Sony closed down 6% in Monday trade.
The company announced late last Friday that it would postpone its earnings release date to next month.
The delay was due to uncertainty over the supply chain from two earthquakes which recently hit southwest Japan.
Sony was initially scheduled to release its earnings this week.
