Welcome to CNBC.com by the Numbers

Like numbers? Yeah, we at CNBC.com do too.

That's why we're introducing "CNBC By the Numbers." Every day the market's twists and turns present a new set of metrics for investors to ponder. It gives rise to questions like "How does today's market stand historically?" and "When was the last time this type of thing happened?"
And at CNBC, we crunch out the calcuations and market factoids to help investors figure out the answers to those questions. And now you can find them here.
Happy Number Crunching.
