Normalizing China demand could pose a near-term threat for ASML, according to Bernstein.
The firm reiterated its outperform rating on the Dutch semiconductor stock, but lowered its price target to $815 from $1,052. This revised price forecast is still approximately 13% higher than where shares of ASML closed on Friday.
Whether stocks can sustain those gains may depend on whether companies can beat expectations this earnings season, which is set to ramp up this week. Roughly one-fifth of S&P 500 companies are set to report through Friday.
Thus far, the results have been mixed. Of the 14% of S&P 500 companies that have already posted third-quarter results, 79% have beaten expectations.
