For opportunistic buyers with capital to deploy, such as private equity, it's time to buy on the cheap and sell out in five years' time. Uncertainty about funding necessary capex is a likely major reason behind depressed valuations in the sector at present.

As a result, I've been dipping a toe in the water of TMT sell-side research and looking for key data points. To cut a long story short, the mood music is that tech analysts are getting increasingly worried, while media analysts remain in a positive frame of mind.

(ORCL) to Hewlett-Packard Co. (HPQ), sees an opportunity in solving it. So EMC Corp.'s (EMC) purchase of Greenplum Inc. won't be the last example of an IT Leviathan buying a small, innovative data warehousing and analytics firm. Aster Data Systems Inc., Vertica Systems, Netezza Corp. (NZ), and even the larger Teradata Corp. (TDC), are potential targets. The interesting question is: Who are the buyers? The database powerhouses -- Oracle, International Business Machines Corp. (IBM) and Microsoft Corp. (MSFT) are not the leading candidates. Instead, EMC's move will inspire other non-database firms to use the warehouse market as a forum to challenge the database leaders.

With demand primed by the government's auction of its TARP warrants, banks and other businesses have a new tool with which to manage their balance sheets -- and one that in some cases may offer cheaper capital.

So reports that the British bank is weighing a bid for SunTrust Banks Inc. (STI) come as little surprise. Indeed, if a deal with SunTrust or another similar-sized bank were to work out, the timing for Barclays couldn't be more right.
