From Dow Jones News' "U.S Stock Futures Waver" posted early Tuesday:
U.S. stock futures wobbled Tuesday, with investors awaiting further developments on the stimulus package and U.S.-China trade relations amid thin trading volumes.
Futures tied to the S&P 500 wavered between muted gains and losses, a day after the benchmark stopped just shy of a record. Overseas, the Stoxx Europe 600 edged up 0.1%.
"This is a typical August, where things are very, very slow," said Seema Shah, chief strategist, Principal Global Investors.
My take: Another slow, wobbly day. No wonder Mr. Premarket has been so confused lately.
UPDATE: While I was looking the other way, Apple made like a streetlight and turned from green to red.
