On August 21, Direxion Daily MU Bull 2X Shares rose 8.08% in regular trading, trading at $32.27/share, with turnover of $856 million. The ETF is a 2x leveraged bull product tracking Micron Technology, whose shares gained over 3% on the same session.

On the news front, Micron Technology announced the establishment of Micron Research Labs, committing $10 billion over the next decade to advance memory technology, advanced packaging, and semiconductor manufacturing. The research hub will be headquartered in Boise, Idaho, with satellite labs globally, positioning the company for next-generation AI computing demand. Additionally, S&P upgraded Micron's credit rating to BBB+, with a positive outlook, reflecting strengthened confidence in the company's near-term demand prospects.

The dual catalysts triggered a technical rebound after Micron had previously plunged over 7% in a single session due to bond market sell-off pressures affecting the broader semiconductor sector.
