S&P 500 now signals Biden win — CFRA's Stovall

This week's sell-off took the S&P 500 below its July 31 close, a signal that former vice president Joe Biden could be the next president.

Sam Stovall, chief investment strategist at CFRA, said the market is trading as if Biden is going to win. There has only been one time that an incumbent president won when the market was lower between July 31 and election day. That was President Dwight Eisenhower in 1956, when the S&P was down 7.7%.

The S&P 500 closed at 3,269 Friday, just below its July 31 close of 3,271. Of course, the election is not until Tuesday, so that could change.

"The presidential predictor, which has been successful 88% of the time since 1944, now points to but does not guarantee a Biden victory," said Stovall. —Patti Domm

Treasury yields rising despite stock sell-off

Stock investors look to be heading for the hills, but so do investors in bonds, usually the bastion of strength and safety during risk-off moments.

Bond strategists say it's month end and it's time for asset re-allocation trades, but on the surface it doesn't look like investors are doing much shifting from bonds to stocks or vice versa.

"Everything tells you the Treasury market should be stable, if not rallying," said National Alliance's Andy Brenner. Yields move opposite price, and the 10-year yield has risen to 0.85%, just below its recent high of 0.87%.

"With the S&P 500 down 1.6%, you're just getting close to levels that should elicit some bounce in Treasurys. Risk parody trades are just not working, " said Brenner.

Ian Lyngen of BMO says it's the pre-election trade in the bond market, where investors expect a post-election stimulus package. The market is anticipating a surge in new debt, particularly if Democrats win the White House and Senate. That means yields would go higher.

But if the election outcome is unclear or contested, Lyngen says to look for yieldto reverse to much lower levels.

Better than expected data, including Friday's consumer sentiment, is also supportive of higher yields.

Watch 3,209 level on S&P 500, Bank of America says

Bank of America's Stephen Suttmeier said 3,209 will be a key level of support for the market, as it could signal a rebound is on the horizon or further selling.

"If the SPX holds above this big support, the potential builds for a bullish triangle that if completed on a decisive breakout above 3525-3550 would favor a continued uptrend to 3830-3860," Suttmeier, the bank's technical research strategist, wrote in a note.

The S&P 500 broke above 3,500 for the first time earlier this year. At one point, the broader-market index traded above 3,580. The S&P 500 traded more than 8% below its all-time high of 3,588.11 on Friday. The index hasn't traded below 3,209 since late July.

Suttmeier also noted that if the S&P 500 breaks below the 3,209 mark, "a more sinister double top" pattern could form.  "The double top scenario would not rule out a decline to the pattern counts at 2870-2830 or just over a 50% retracement of the March-October 2020 rally." —Fred Imbert, Michael Bloom

Apple shares slide on weak iPhone sales

Shares of tech giant Apple dropped more than 4% in the premarket after the company said iPhone sales dropped 20.7% during its fiscal fourth quarter. Apple's revenue from its services business, iPads and Mac computers were strong, but not enough to make up for the iPhone revenue decline.

Apple also refrained from issuing guidance for the current quarter.

"If you look at the case count, the case counts are climbing in Western Europe. They're climbing in the United States. And so there's still a sufficient level of uncertainty out there… we don't believe that's an environment to guide into," Apple CEO Tim Cook told CNBC's Josh Lipton. —Fred Imbert, Kif Leswing
