DJIA Today: Bank of Japan Announces More Stimulus, Dow Jones Slips

On Tuesday, we watched the Dow shed another 90 points as the markets walk back from record levels just two weeks ago. At the time that the Dow was in the stratosphere, we warned that stocks were overheating. The key difference this time is that markets are still sliding despite news that global central banks are pumping even more stimulus into their economies and interest rates continue to plunge.

Berkshire Hathaway Inc. (NYSE: BRK-A) Chairman Warren Buffett generated headlines on Tuesday after he criticized Republican presidential nominee Donald Trump. The two men squabbled publicly after Buffett criticized Trump's recent spat with the family of a Muslim-American serviceman who died in the Iraq war. Although he is supporting Hillary Clinton for president, Buffett's statements are unusual given his penchant to stay away from politics. Instead, Buffett may be better known for his statements about times of financial uncertainty. Given that we are surrounded by such economic uncertainty, Buffett's words may never be truer.
