Billionaire investor Ron Baron isn't flinching during the latest tech selloff, and he's certainly not touching his own Tesla shares, he said. The longtime growth investor said he sees the pullback as a chance to spot bargains, even as volatility has rattled the biggest names in tech recently. "Not very much," Baron said Friday on CNBC's " Squawk Box " when asked what he's doing amid the drawdown. "Just looking and trying to understand where opportunities are and try to take advantage of them."
