A top economist says the stock-market mania reminds him of the dot-com and housing bubbles - and warns consumers are feeling the squeeze

• David Rosenberg warned the buzz around stocks today is similar to the mania before past crashes.
• He highlighted the Great Crash of 1929, the dot-com bubble bursting, and the financial crisis.
• The economist noted that American consumers are running short of cash and struggling to borrow more.

The feverish excitement around stocks today is similar to the mania that preceded the Great Crash of 1929, the dot-com bubble bursting in the early 2000s, and the housing market's collapse in 2008, David Rosenberg has warned.
