Micron's positive earnings report and strong guidance directly impact its stock price, indicating a robust demand for its products and a positive outlook for the company. This performance not only boosts Micron's stock but also has a favorable impact on related tech sector stocks, including Seagate.

Seagate's stock performance is closely tied to the broader tech sector, especially companies like Micron that share a similar market.
