Wall Street drifted to a mixed finish after Tesla surged and IBM slumped following their latest profit reports.

The surprise increase was the first since the electric-car maker’s earnings began to slide earlier this year as it turned to deep price cuts and other sales promotions to stimulate sales.

Wall Street is holding steadier, thanks in part to a surge for Tesla’s stock. The S&P 500 rose 0.2% Thursday and was on track to break its first three-day losing streak since early September.
