It looks to me that Toyota
It looks to me that Toyota Motor Company (ADR: TM) stock came back quite well after the government announced there was no electronic fault. So, the drop in the stock was temporary. Even today where all stocks are affected by the general market Toyota is holding up well.
The issue as I see it revolves around the alleged internal corporate cover up to protect the image built up over the years. Stock laws do cross borders to some degree, as the basis for equities are the same via the exchanges.
I will follow-up soon on a TM auto sector article after I inspect the chart patterns. The article here benefits those who want to understand the fundamental reasons behind the price moves. Both are needed to be an informed trader.
