As Nintendo prepared to launch Super Mario Run, their stock value was on the rise, reaching a number near the heights of the Pokémon GO craze. However, since the app launched, it's been an entirely different story. Nintendo's stock took a hit of over 4% immediately after Super Mario Run released, and it plunged even further after the weekend. Nintendo's value declined by another 7% today.
This brings the company's market cap to ¥3.48 trillion, down from ¥4.14 trillion just one week ago. In other words, the company's overall market value declined by ¥660 billion. Converted to US currency, that's over $5.6 billion. Analysts believe this plunge is caused by factors like the game's $10 price tag and required online connection.
