Today, the Big N slashed their FY 2012 earnings guidance by 82%. They also announced a huge price cut on the 3DS system from $250 to $170. These are the moments that value investing is made for. Was I wrong to buy NTDOY, Nintendo’s ADR, at $33/share? Well it is trading below $20/share today, so the answer has to be yes. Was I wrong to buy Nintendo at $28/share? Yes again. Was it wrong to buy Nintendo at $22/share? Time will tell. My investment time horizon on Nintendo is 3-5 years and the case for revenue growth will become more compelling as the Wii U rolls out. This coupled with more releases of quality 3DS titles could stem the bearish tide.
