Tesla stock's slump has wiped out nearly $700 billion in market capitalization from a year-ago peak, and Wall Street is starting to say enough is enough.

In fact, even a noted Tesla bear has upgraded the stock to "neutral" from "sell," saying it has likely bottomed.

"We believe the year-to-date pullback has balanced out the near-term risk/reward," Citi analyst Itay Michaeli said in a note Wednesday.

In addition to upgrading Tesla stock, Michaeli raised his price target to $176 from $141.33, though the new one is still below where shares last traded as they jumped 8% to top $183 on Wednesday.

"To be sure, macro/competitive concerns are likely to remain an overhang with capacity rising, but as we've previously written, in a hard landing scenario Tesla's long-term competitive position likely also improves and potentially further enhanced by [President Joe Biden's inflation reduction act]."

Tesla bull Jonas said in a note Wednesday that shares were nearing his "bear case" price target of $150, indicating a potential buying opportunity at a deep discount.

"We believe Tesla's 'gap-to-competition' can potentially widen, particularly as EV prices pivot from inflationary to deflationary," he wrote. "With respect to the (inflation reduction act) we believe Tesla is by far the best positioned OEM in terms of potential eligibility for consumer tax and production credits."

Meanwhile, Cathie Wood said in an interview with Bloomberg TV on Tuesday; she reiterated her optimism.

"Many people say, 'aren't you worried about Tesla?' No we're not because of our work on electric vehicles. They are grabbing at a disproportionate share and will continue to do so of a market that we think, by 2027, will account for 85% to 95% of all cars sold in the world. That's on automatic pilot. He's [Elon Musk] now working on autonomous which we think is going to work."

"We think Tesla is going to do it [autonomous] in a much bigger way."
