Citi raised its price target on Micron (MU) to $175 from $150 as it expects the A.I. player to guide well-above Wall Street estimates. Marley Kayden notes the stock's significant rally on the price target raise, along with how it's "riding on the back" of Oracle's (ORCL) earnings. However, she adds that it raises the bar for Micron and similar stocks moving forward.
