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.

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.

Despite Tesla publishing a weak deliveries report in early January, TSLA continues trading in the green and analyst keep rating it as 'buy.'
