A slang term referring to speculative stocks that have short or
suspicious histories for sales, earnings, dividends, etc. The origin for
this term may have stemmed from the use of "dog" to refer to
an underperforming stock.
In a bull market, analysts will often mention that everything is going
up, even the cats and dogs. Therefore, during this time, new investors
should not to be too overconfident in their stock picking ability,
because even picking the most flawed investment could yield good returns
- at least at first.
