TSLA suddenly surged 7.6% yesterday, has retail sentiment changed? 🔥

Over the past month, $Tesla(TSLA.US) has been tough to watch—it's down over 20% year-to-date, at most 30% off its 52-week high, and Q1 deliveries nearly fell into a trap, with sentiment hitting rock bottom. But just yesterday, TSLA surged 7.6% in a single day, bringing the stock price back to around $392.

🔔 What triggered this rally?

First, Musk posted a picture of Tesla's new AI chip on X—codenamed AI5, designed to power the humanoid robot Optimus and Tesla's in-house supercomputer. The official statement said it has "completed a key engineering milestone and is nearing mass production." Just one post with a chip picture was enough. Second, Wall Street giant UBS upgraded TSLA from "Sell" to "Hold" on the same day, with a target price of $360. Although $360 is still lower than the current price, the shift from "Sell" to "Not Selling" is a signal at the sentiment level. These two pieces of news caused a noticeable spike in TSLA mentions on X and StockTwits yesterday.

📊 Sentiment shifts across platforms over the past 48 hours

X platform (formerly Twitter): Mention volume expanded significantly, with core keywords being "AI5," "Musk," and "chip." Sentiment leaned towards curiosity and optimism. Musk's own post garnered over a million interactions within hours, and retail investors quickly joined the discussions about the potential of Optimus and Tesla's in-house AI.

Reddit: Sentiment hasn't fully reversed yet, but there's improvement. Over the past month, Reddit's TSLA sentiment score dropped to 28 (out of 100), in bearish territory. There was a slight rebound in the last 24 hours due to the AI5 news, but mainstream posts are still filled with concerns about deliveries and Musk's political controversies. A pinned post on r/stocks titled "Tesla Delivery Declines Could Enter Third Year" remains highly discussed.

StockTwits: Over the past 48 hours, the bull-bear ratio showed a noticeable shift. Bullish sentiment recovered from previous lows but hasn't returned to optimistic dominance yet. Day traders were most active yesterday, focusing on intraday swings.

Searches for "Tesla AI chip," "AI5," and "Tesla chip reveal" spiked between April 14th and 15th, driven by the event rather than sustained interest growth. Similar search peaks occurred when the Optimus robot was unveiled previously, with the heat typically lasting 2-3 days before fading.

💬 What are people discussing?

Key points from the bullish side:
The AI5 chip suggests Tesla may no longer need to purchase NVIDIA GPUs on a massive scale, reducing costs while enhancing in-house capabilities; the Optimus robot narrative has been reactivated; the Netherlands became the first European country to approve FSD (Full Self-Driving) software, opening a breakthrough in the European market; additionally, Tesla and SpaceX are jointly building two chip factories in Austin, accelerating supply chain autonomy.

Key points from the bearish side:
Q1 deliveries of 358k units fell short of the expected 370k, with inventory backlog hitting a record high of around 164k units; registrations in some European markets dropped 49% year-over-year; Musk's political image continues to drag down the brand; JP Morgan maintains a $145 target price, suggesting a further 60% downside; SpaceX's upcoming IPO is seen by some as a distraction for Musk's focus and market capital.

My take: This AI5-driven rebound is a sentiment repair, not a fundamental reversal. Retail sentiment shifted from "extremely pessimistic" back to "cautiously watching." The fact that just a chip picture achieved this effect shows that the Tesla story still has power—as long as Musk is willing to tell it. However, substantive issues like inventory backlog and missed delivery targets haven't been resolved. The Dutch FSD approval is a positive signal worth tracking for follow-up actions in other European countries. Short-term sentiment has recovered, but this stock's high volatility hasn't changed, and the risk of retail investors getting shaken out by the swings remains high.
