Actually what you guys are looking at is not public stock. However their public stock as already mentioned, is NTDOY. The more expensive stock, is a japanese stock not made to the public, if it is... its not the public stock that is booming... and not for the average person.
I had 1k this semester so I new I'd spend it, so in september i invested it in nintendo (ntdoy) at 24.85! so i'm glad it has gone up 13% in one month to 28.65... which is awesome. so research it at etrade.com ... ntdoy
Basically this is the public stock.. it has gained 13% in a month which is amazing. this week it has gone up 1-2% each day... so i'm hoping this continues until dec 2nd when it is released in japan. then i have to sell it to pay off my 900$ credit card debt lol... but im hoping it increases another 13% so i return a profit after sales.
etrade.com lets you buy it for 1k$ but you have to wait a few days for your money to clear to purchase overseas stock. even then, if you chooses hte instant cash option they dont let you buy japanese stock for 7 days! i had to call to have my trade sent through afte r8 complaints. however when i wanted to buy it in sept, it was 27$.. after bitching at etrade it was 24.85... so it was a blessing i cant complain lol. after... its back to 28 so i gained

so make sure if you buy the stock you get ntdoy, not the really really expensive non public stock!
