NEST? The stock that jumped 1900%? Wrong Nest

This final note in which we’re obliged to again caution investors to double check those ticker symbols before hitting the buy button.

Remember when Twitter went public and shares of a home entertainment company with the symbol TWTRQ went bananas.

It happened again today with the ticket symbol NEST, which is not the thermostat company Google spend $3.2 billion to buy.

NEST is in fact a penny stock — a bankrupt red-light traffic camera company, in point of fact.

But at one point today, shares were up 1,900 percent to $0.10.
