Following in the footsteps of the Federal Reserve post-2008 financial crisis, the Bank of Japan announced overnight that it would inject $1.4 trillion into the economy over the next two years as a stimulus measure. As a result, the Japanese Yen took a nose dive as the currency is debauched even further and stocks around the globe, including the Nikkei 225 and S&P 500, rose considerably on the news.
As you can see in the chart above, the Nikkei 225 has ripped to the upside, posting a +5.2% gain in the last two days alone. Insider buying and selling is inevitable but any kind of easing program put into place by Japan's central bank is bound to make waves in the stock market.
