The PHLX Semiconductor index has become a volatility show, with big players seeing large daily swings.

Investors are banking on a few dozen newly valuable companies to deliver nearly half of S&P 500 profit growth for the second quarter.

The mercurial trading in chipmakers this month reflects the high stakes of the current earnings season.

Wall Street’s earnings season is entering a critical phase as attention shifts from early reporters to a concentrated batch of high-profile results scheduled for release in the coming week.

The market is now looking to major semiconductor names to validate the broader rally that has been building since Micron Technology’s robust quarterly performance served as a catalyst for the sector.

The memory chip maker’s results have reinforced investor confidence in the industry’s recovery, but the sheer magnitude of the expected profit contribution from the sector creates a binary risk.
