It's time to ignore sideline analysts who have been consistently wrong about Google ( GOOG), Jim Cramer told viewers of his "Mad Money" TV show Wednesday. Every time Google's stock rises, bears scream that it's expensive and scary. At every benchmark, people have said that Google's market growth is too high. "At this point you have a duty to yourself and a duty to your wealth," Cramer said, "never to take financial advice from anyone who doesn't recommend Google." Analysts that knock Google can only be so wrong about a stock for so long before admitting they're wrong, he said, and it's time for investors to stop paying attention to the bears. Cramer said his price target for Google has always been lower than where he actually thinks it's going to go. Cramer then raised his price target to $750. "This is a total and unequivocal lowball estimate," Cramer said.
