Infosys reported horrible guidance. This is should cause IBM to take a hit today. Could be an interesting set up for a short-term trade. (Buy IBM on today's weakness then sell into the run-up before earnings.)
For the record, IBM should produce decent earnings as they are taking share from competitors. (I do not know if they will see the same level of appreciation after they report this quarter because its run up so much.)
Oracle and Accenture produced good quarters, which set the tone for the IT/tech sector's recent run. Infosys seems like a company specific issue, just like Oracle was laster quarter.
update: SAP just chimed in regarding their company specific poor sales execution.
