Tech Giants Set to Report Earnings Wednesday—And Big Stock Moves Are Likely

Major Big Tech earnings (Alphabet, Amazon, Meta and Microsoft) due after the close Wednesday are expected to trigger notable volatility and could materially move the US Tech 100 index. Options-implied moves suggest swings into the mid-single digits for each stock (Alphabet ~5%, Amazon ~7%, Meta ~6.5%, Microsoft ~6.5%), which could push individual names to fresh highs or pull them back and weigh on the index. AI-driven revenue upside (AWS, Google/GenAI, ad gains at Meta) is a key upside catalyst, while investor focus on heavy AI spending and guidance raises downside risk. Apple follows on Thursday, adding to near-term tech-sector event risk. Overall, the earnings cadence is a potential market-moving catalyst for the tech-heavy US Tech 100.
