Hi Liz,
Unfortunately, while increased demand for a company’s product creates a tailwind for earnings it far from guarantees the stock will rally, just think lithium over recent months.
In the case of Dutch Company ASML, who makes the extreme ultraviolet (EUV) lithography machines that are critical for manufacturing advanced semiconductors, the stock has struggled of late on concerns the chip-equipment maker may face cuts to orders of 20-30% next year. i.e. stocks price the future, not the now. We are neutral at this stage until we see further signs from leading indicators on future demand.
