Tesla shares have slumped more than 8.3% since the group's 'We Robot' event earlier this month in Los Angeles.

Tesla Inc (NASDAQ:TSLA) could address key topics like its sub-$30,000 vehicle, the rollout timeline for its robotaxi, and other pressing questions from investors and analysts when it reports its third-quarter financial results after market close Wednesday.

Wall Street analysts expect a drop in Tesla's third-quarter margins after it boosted incentives to juice sales of its aging core vehicles, the Model Y crossover and Model 3 sedan.
