Patrick Cox, Transformational Technology Alert editor, kicks off this week's Charts That Matter with a look at what happened to Mylan Pharmaceuticals' market share and stock price when the company decided to charge $300 rather than $50 for an EpiPen. Then Rational Bear editor Kevin Brekke takes over, with charts on the impact of the proposed tax reforms on municipal bonds, the long-term downtrend in US housing starts, a 2017 aberration in retail stocks, and a breakdown on the shifting composition of household debt, which is at a historical high.
