Business models don't get enough scrutiny. This morning when I interviewed Vernon Hill, the CEO of

Commerce Bancorp

(CBH) - Get Report

, on RealMoney Radio, I was struck by his ability to measure a company by its model,

regardless

of who runs it. He was openly critical of

Bank of America

(BAC) - Get Report

-- his largest source of new business, and skeptical of

JPMorgan Chase

(JPM) - Get Report

because, alas, their models don't stress same-store growth. Instead, they either pile on the branches regardless of how they do or try to cut corners and cut out branches entirely. And boy, does he hate it if you call his stores "branches."

I know that I emphasize growth endlessly, but I, too, don't think enough about business models, and I did much more of that thinking when I was back at my hedge fund.

Simply put, as I watch the Internet sell off, I am thinking about what Vernon said. These Internet companies all have a fantastic viral model that would make any retailer just plain jealous. They have no inventory and no branches, and their biggest cost is electricity (which

Rackable

(RACK)

is taking care of).

I believe that the selling in these Internet companies can last another day or two, but not more. The business models just generate too much money and are too capable of expansion endlessly before they run out of room.
