IPO

Weighing the evidence objectively, the intelligent investor should conclude that IPO does not stand only for “initial public offering.” More accurately, it is also shorthand for:
It’s Probably Overpriced,
Imaginary Profits Only,
Insiders’ Private Opportunity, or
Idiotic, Preposterous, and Outrageous.
