Ideas
Romaine Bostick Anchor, Bloomberg 0:15
Iran headline pressures stocks; September weak.
The Iran headline sent the S&P 500 to session lows with most S&P names lower, and September is historically the weakest month for stocks, creating a cautious equity backdrop.

Iran tensions push oil, energy higher.
U.S. strikes on Iranian tankers near Kharg Island are adding supply risk and volatility, pushing Brent crude back toward $99; higher oil and record U.S. diesel prices are giving energy stocks a bid.

S&P 500 inclusion lifts shares.
Bloom Energy and Everpure rallied after S&P Dow Jones Indices said late Friday that the companies will join the S&P 500 effective before the open on September 21, driving index-demand buying.

Government stakes boost quantum stocks.
The U.S. government is taking minority equity stakes in quantum computing companies, fueling rallies in D-Wave Quantum, Rigetti Computing, and Quantum Computing.
Carol Massar Anchor, Bloomberg 3:55
Upgrade, price hikes lift Intel.
DigiTimes reported that Intel is expected to raise prices, and Northland Securities upgraded the chipmaker to outperform with a $120 price target implying about 25% upside.
Carol Massar Anchor, Bloomberg 4:35
Novartis failure, downgrade hit Amgen.
Novartis's failed final-stage heart drug trial is a negative signal for Amgen's similar program, and BMO Capital Markets cut Amgen to market perform.
Carol Massar Anchor, Bloomberg 5:18
Weak summer alcohol demand hits Constellation.
Constellation Brands management said the off-premise business was lackluster over the summer and August weakened as gas and diesel prices spiked, pressuring alcohol demand.
Carol Massar Anchor, Bloomberg 5:53
Trump risk weighs on Bombardier.
President Trump suggested Bombardier should be blocked from U.S. sales unless it builds in the U.S., creating headline and regulatory risk for the stock.
