Futures Drop As Apple-Led Tech Slide Deepens

U.S. stock futures dropped by up to 1 percent on Tuesday as a technology rout in the previous session. Concerns over iPhone sales sapped investors’ appetite for high-growth companies.

Shares of Apple Inc lost 1.4 percent in premarket trading, putting it on course for its seventh decline in the past nine sessions. That's around 20 percent down from a peak earlier this year that valued it at more than $1 trillion.
