Tesla stock has hit a rough patch in recent weeks, but top analysts still see big gains ahead for the EV maker's stock this year.

Tesla shares have slowed their post-election rally and have underperformed the Nasdaq since the start of the year.

The analyst also noted in a CNBC interview that Tesla owners paying the additional $8,000 upgrade for existing vehicles to adopt FSD would result in a big boost in profit margin. That would help provide a return on the huge amount of capital Tesla spends on artificial intelligence (AI) infrastructure to develop FSD.

Tesla shares have gained ground the past two sessions after a five-day losing streak during which the stock lost 18% of its value. Monitor these important chart levels.

Tesla stock slipped on Tuesday after Bank of America said it sees shares fairly priced, with some risk to the downside.
