The recession has started.

At least, that’s what Canaccord Adams analyst Peter Misek thinks. In a research note this morning, he cautions that global tech spending is likely to slow down in 2008, and says he has become decidedly more cautious on the outlook for the first half. “We must accept the reality that investors with a 6-9 month time horizon are likely to experience considerable volatility and undersized returns,” he writes.

Canaccord downgraded Research In Motion (RIMM), Converse (CMVT.PK), BEA Systems (BEAS), Citrix (CTXS) and Certicom (CIC.TO) to Hold from Buy.

He also cut target prices on Absolute Software (ABT.TO), Intrisync (ICS.TO), Cerner (CERN), IBM (IBM) and Redknee (RKN.L)

  • Research In Motion is down $4.23, or 4.2%, to $96.43.
