Dow and S&P 500 fall amid oil rally and inflation fears, Nasdaq snaps winning streak

The Dow and S&P 500 finished lower while the Nasdaq ended its three-day winning streak as a rally in oil prices fueled inflation concerns. Semiconductor stocks declined, contributing to the market's weakness.

Why it matters: Traders increased bets on Fed rate hikes ahead of key inflation data, and fears over Iran also weighed on the Dow's outlook.
