Don't Buy Amazon Here

Amazon (AMZN) - Get Report has pulled back nearly 10% after hitting an all-time high last week, but dip buyers should remember that RadioShack once seemed like a bargain, too --until its stock fell to zero, TheStreet's David Yoe Williams says.

"At a certain point when RadioShack was starting to fade, it [looked like] a buy at $15, $10, $5, a dollar-and-a-half -- [except] it wasn't," Williams said during TheStreet's August Trading Strategies roundtable discussion.

"Everybody said Amazon was so great and [is] going to kill [traditional] retail, but come to find out maybe it hasn't," he said. "It's really only 20 percent of the market."
