Stock futures are holding steady Wednesday as investors prepare for a Federal Reserve announcement on interest rates and earnings reports from major technology companies.

Broadcom stock rallied 2% to hit a new high, while Palantir gained 0.4%, bouncing back from Monday's losses. Tesla skidded more than 1%, as it still tries to regain its 50-day moving average. And Uber stock steered 2.5% lower, threatening to breach its own 50-day line for the first time since late April.
