Tesla stock has soared this week on easing U.S.-China tensions. Some market watchers say the stock's rally is setting off alarm bells. Tesla (TSLA) "is flashing overbought technicals,” wrote Matthew Unterman,

U.S. tariffs on Chinese goods were reduced to 30% for a period of 90 days, while Chinese tariffs on U.S. goods were lowered from 125% to 10%.

Management may continue to dangle the carrot of new prototypes to keep shareholders happy. Cathie Wood may still have a price target of $2,600. But smart investors know that a stock follows its fundamentals over the long term, which is why Tesla stock is much more likely to crash than soar at current levels. Don't buy it for your portfolio today.
