The stock market price of Japanese gaming specialist Nintendo has declined for four straight days in a row.
The company's total value has now decreased by over 15 per cent since the end of February.
As reported by Andriasang, investment services company Fisco primarily points the finger at the disruption caused by the aftermath of the Japanese earthquake.
In addition, the High Street has also seen a number of key titles delayed – a factor that Fisco directly speculates has lead to a slump in 3DS sales.
The PSP overtook the machine in the weekly sales race last week.
3DS has sold a total of 836k units so far in Japan since its launch in late February. Nintendo had previously pledged to ship 1.5m units to the territory by the end of last month.
