Barron's DOW 30k Cover: Contrarian Indicator of A Stock Crash or Melt Up, Crack Up Boom Accelerating?

Barron's investing magazine just put DOW 30k on their cover for this week's new issue predicting that the DOW will hit 30k soon. 

Jason briefly talks about the history of Wall Street magazine covers from Barron's, Fortune, Business Week, etc predicting markets already in up trends going a lot higher or other outlandish predictions. 

Are these magazine covers still reliable contrarian indicators which could indicate that a stock market crash for US stocks is coming soon or is the melt up, Ludwig Von Mises' style crack up boom well underway and accelerating rapidly like in 1927-1929?
