No, the problems in the Chinese auto industry–a big customer for Nidec’s (NJDCY) small motors and electric drive trains–didn’t suddenly spike and cut Nidec’s share price in half.
The Japanese company executed a 2/1 split on April 9.
I bought these shares in my 50 Stocks long-term portfolio on July 11, 2017 at what was then $25.46.(I added them to the portfolio as a play on the continued growth of the electric car sector, especially in China.) After the split the purchase price goes to $12.73. The stock was trading at $13.39 as of 2:30 p.m. New York time on Thursday, April 16.
