Shares in Nintendo plunged nearly 10 per cent today despite strong sales of its Wii game machine helping drive robust quarterly profits.
Shares in Nintendo fell 9.7 per cent today, hitting their downward daily limit of 46,800 yen and extending their losing streak to a third trading day.
The stock was hit by fears that a firmer yen could hurt earnings.
Analysts said the stock also came under pressure as some institutional investors, who had bought heavily into the stock during its meteoric rise over the past couple of years, pocketed profits amid a slide on global share markets.
But they said the shares - which have fallen by a third in the past three months - may have been oversold given Nintendo's rising production capacity and strong earnings momentum.
