The last week of June marks the tail of first-quarter earnings season, and it closes with the name most investors have been waiting for: Micron Technology, Inc. (MU).

The AI-memory giant has rallied 300% this year and crossed $1 trillion in market value, riding a wave of investment into artificial intelligence infrastructure that has made semiconductors its largest beneficiaries.

Options are now pricing a 14% post-earnings swing in Micron.

Beyond Micron, the week brings nine more names carrying large implied moves, according to market data.

An implied move is the size of the post-earnings swing options traders are paying to hedge against, derived from the price of at-the-money calls and puts.

The figures below come from an earnings screen filtered by market capitalization above $10 billion.

Here is the week, counted down from the smallest expected move to the largest.
