Micron AI chip earnings surge as Vanguard ETF outperforms SPDR on cost

Micron Technology reported quarterly earnings that far exceeded Wall Street expectations, driven by strong demand for AI memory chips and $22 billion of customer commitments. The semiconductor maker’s shares jumped more than 16%, lifting the broader AI‑related chip sector, while Apple’s price hikes weighed on the Nasdaq.

A separate analysis compared the Vanguard S&P 500 ETF (VOO) with the State Street SPDR S&P 500 ETF (SPY). VOO offers a lower expense ratio of 0.03% versus 0.09% for SPY and holds a larger asset base of $1.7 trillion, making it the cheaper option for long‑term investors despite similar performance and sector exposure.

Both pieces highlight continued investor focus on cost efficiency and real revenue growth in technology‑heavy U.S. equities.
