Tesla had a rough day

The dip comes after more than three months of steady gains, minus the volatility that has characterized Tesla's stock price for the second half of 2014.

Since bottoming out at $185 per share on March 27, the stock has rebounded big time, ended last week at $280.

We're not really sure exactly what triggered Tuesday's selloff.

However, Deutsche Bank analyst Rod Lache published a note Tuesday downgrading Tesla from "buy" to "hold." Deutsche Bank upped its target price t0 $280 from $245, but the Lache wrote that value of its Tesla future potential has already been factored into the current price.

"And we believe that TSLA could become a dominant player," he wrote. "But at this point, Tesla's shares appear to already reflect this opportunity."
