Previous Close

It's 6:28 am California time, 9:28 am New York time. Shares of BluhBlahBloh, the greatest mumbling company on the planet, are indicated "up big" by Cramer. Yeah, the Mad Money guy. You glance at the CNBC scroll and see the stock indicated at $25-$27, but its opening is delayed because there are so many bidders wanting to buy. And of course you wonder, since you own it, what it closed for yesterday, so that if it opens at $28.28, you know just how much dough you've made in the last half day and change on this investment.

That price, where it closed at the end of the day yesterday, was its previous close.
