Did it really feel like a short week to anybody?

TheStreet.com Internet Sector

index closed up 17.22, or 1.5%, at 1162.30. Considering it began the week at 1108.59, the nearly 54-point move does not seem like a big deal.

But there was much volatility in the sector, and while traditional Net stocks that make up the DOT were marginally higher, other hot

B2B plays and members of

TheStreet.com New Tech 30 took off.

VerticalNet

(VERT)

was off to the moon, finishing up 56 7/16, or 29.2%, at 252 1/16 on news of a $100 million investment from

. Under the terms of the agreement, Microsoft will provide Web distribution for VerticalNet, which operates more than 50 portals aimed at specific industries. Following the news,

Lehman Brothers

, which has done underwriting for VerticalNet, upped its price target on the stock to 350 from 170.
