Tesla stock climbs 2.1% as Arizona robotaxi approval boosts outlook
As of September 22, Tesla stock is trading at $425.50, up 2.1% in the past 24 hours. This marks a continuation of bullish momentum that began earlier this month and has been driven by investor confidence and regulatory catalysts.
Highlights
- Tesla stock climbed 2.1% to $425.50 following Arizona’s approval for robotaxi testing.
- Technical indicators remain bullish, with the stock trading above key moving averages.
- While momentum is strong, upcoming earnings and regulatory developments will shape the next price move.
Technically, Tesla has broken above its 50-day and 100-day moving averages, which are now acting as near-term support. The 20-day moving average sits around $418, while the 100-day average has moved up to the $405–$410 zone, reinforcing a bullish trend structure. The 200-day moving average—often used to define long-term trend direction—remains positively sloped and now lies near the $380 level. As long as Tesla maintains support above this zone, bulls remain in control.
Momentum indicators are also supportive. The 14-day Relative Strength Index (RSI) is currently around 71, suggesting the stock is entering overbought territory. This doesn't immediately imply a reversal, but it does increase the risk of short-term consolidation. The MACD (moving average convergence divergence) remains firmly in positive territory, with a widening histogram that points to strengthening upside momentum.

Support levels are now seen near $418 (20-day MA), and further below at $400–$405. Resistance is shaping up near $430, with a breakout above this level potentially clearing the path toward the 52-week high at $488.54. Given the bullish technical setup, a breakout looks more likely than a reversal—though short-term volatility could test support zones before continuation.
Robotaxi approval and Musk's confidence offset weak Q2 earnings
The recent surge in Tesla shares is largely attributed to two interlinked developments: regulatory progress on its robotaxi ambitions and renewed confidence from CEO Elon Musk. Earlier this week, Tesla received regulatory approval from Arizona’s Department of Transportation to begin testing autonomous robotaxis in the Phoenix metro area, with safety drivers onboard. This makes Arizona one of the first U.S. states to formally authorize Tesla’s autonomous vehicle testing program, validating Musk’s long-term vision for Tesla’s future beyond EV sales.
This move follows Tesla’s broader strategy to pivot toward monetizing its Full Self-Driving (FSD) technology, with the goal of launching a commercial robotaxi network. While approvals are still pending in states like California and Texas, Arizona's greenlight signals that state-level regulatory support is possible—even in the absence of federal guidelines. Investors have responded positively, viewing the robotaxi business as a major margin expansion opportunity in the medium term.
In parallel, Elon Musk disclosed buying over $1 billion in Tesla shares over the last several weeks, a move that has reassured shareholders amid weaker financial performance. Musk’s purchases were interpreted as a strong internal signal that Tesla is undervalued relative to its future potential, particularly as the company navigates a transition period where growth is being driven less by EV volume and more by software, AI, and network monetization.
Bullish bias remains, but consolidation likely
The bullish scenario sees Tesla breaking above $430 resistance and advancing toward the $460–$480 range. This would require further regulatory wins (especially in larger states like California), positive sentiment from institutional investors, or progress on FSD deployment. In this case, a retest of the $488.54 52-week high would be plausible before year-end. A breakout of this magnitude could also trigger momentum-driven buying from algorithmic traders and hedge funds.
The base case, however, is a consolidation between $400 and $430, as overbought technicals and profit-taking cap near-term upside. This scenario assumes no major breakthroughs or setbacks, with investors waiting for Q3 earnings and updated delivery numbers in October. In such a range-bound environment, intraday volatility may increase as traders respond to macro headlines and sector rotation.
Goldman Sachs’ Mark Delaney raised Tesla’s 12-month price target from $300 to $395, citing long-term potential in robotics and autonomy. However, the revised target remains below current levels, reflecting cautious near-term expectations.
