Arm looks wildly overvalued at nearly a $500 billion market cap, about 96x sales and 150x next-twelve-month earnings. The euphoria shows in @steve2bacon calling it the easiest hold ever. x.com 

Arm is still expensive at about 40x revenue with only 20% growth, so it has not fallen enough. x.com 

Arm remains a long-term winner over the next 10 years, but not a short-term buy after running too far, too fast. Its performance has to catch up with at least part of the move, so buying at these levels carries elevated risk if a negative surprise hits. x.com 

Arm Holdings is expensive against its earnings, trading at 92x forward earnings versus a typical 38x for chipmakers. At 38x next year's $3.05 EPS, fair value runs roughly $102-$130, so at $281.30 buyers pay about 116% over fair value. This is a levels-only view from reported earnings and revenue estimates, with no fundamental work. x.com 

Arm Holdings looks unattractive because its nearly 300 P/E ratio is difficult to justify against only 22% year-over-year revenue growth. x.com 

Arm shows institutions being greedy while others are fearful. Smart money did not participate at all in last month's selloff, even as the stock fell 50% from its all-time high, and volume and price patterns are very clear. A $20M roll up and out into November $320 calls adds to the bullish positioning. x.com  x.com 

Arm remains wildly overvalued even after falling 175 points from its top, still trading at 336x earnings, 236x forward earnings and 61.5x sales. Eventually the bids will stop, there will be no bailout rally and chasers will be forced to learn the fundamentals. The price target remains $100-120, reached slowly and then all of a sudden. x.com 

Arm's forward P/E near 190 already prices in much of its expected growth, leaving a limited margin of safety. Its fundamentals are sound and AI and data center demand is strong, but a long-term position is better taken after a valuation pullback or further earnings delivery. x.com 

Arm is not worth buying more at about 150x forward earnings. The bottleneck it addresses and its pricing power are real, but it is still unproven whether Arm can capture enough of the profit to justify that multiple. x.com 

Arm's post-earnings rise makes little sense at over 40x sales, because the results did not justify it. Remaining performance obligations fell and consensus numbers saw only very modest adjustments, yet the shares rose after successive double-digit moves. x.com
