RealMoney's bloggers were all over the market's moves this past week, and this weekend we'd like to share the Best of the Blogs with TheStreet.com readers. As always, these posts represent the best our writers offer each trading day. This week, take a look at Jim Cramer on the AT&T- Bell South merger, Rev Shark on the benefits of periodically selling everything you own, Steve Smith on moves toward a single platform for option and equity trading and Tony Crescenzi on the next big trade. Cramer's Blog: AT&T-BellSouth Join Mainly to Fight CableOriginally published 03/06/2006 at 10:19 a.m. Bad for cable. Bad for vendors. Yeah, people are scrambling for takeaways from the AT&T ( T) deal . They want to buy Alltel ( AT) and they want to buy Sprint ( S) and they want to see if Verizon ( VZ) makes a bid for Vodaphone ( VOD) or vice versa -- probably the latter. They even have a rap on the vendors that will win from this -- Alcatel ( ALA) -- and the vendors that will lose -- Lucent ( LU). (It's always Lucent, because Lucent's been talking about the big orders from AT&T, nee SBC, for two years now, and the only thing more frustrating for them is China.) I look at it very differently. I believe this is, again, about stopping cable. I say that because AT&T is the DSL company, and it thinks of nothing but giving away DSL so that cable gets hurt. I prefer my cable Internet service to DSL, but I am not price-sensitive, which puts me in the rarefied 1% of customers that AT&T could care less about. Anytime any phone company does something aggressive, it is about cable, because if they don't get aggressive, cable takes their bread and butter away. These Baby Bell companies can't raise price to save their lives, so their business is all about the value added, and AT&T has been much more aggressive with DSL than anybody else.
