Jim Cramer is monitoring 12 stocks, including Netflix, Arm, and Planet Fitness.

Some tickers on my radar for Monday, September 18, as reported by my notebook.

• Netflix's (NFLX) price target is cut to $500 per share from $550, while the outperform (buy) rating is kept. However, margins are going down. The Hollywood strike is bad for business. Despite big demand for Netflix ad inventory, there isn't enough inventory available.
• Citi lowers AAL's price to $15.25 from $16.60, while analysts reduce DAL's PT from $67 to $64.
• The U.K. chip designer, Bernstein, started trading on the public markets with an underperform (sell) rating. On Thursday, the company's stock price increased by nearly 25%. However, on Friday, Arm's stock price dropped nearly 4.5%. On Monday, the company's stock price fell another 3%.

• The White House national security adviser Jake Sullivan and Chinese Foreign Minister Wang Yi had a meeting in Malta over the weekend. The talks were described as "candid, substantive and constructive" by both parties.
• Some China Evergrande employees at the wealth management division have been detained by China.
• MoffetNathanson downgrades PYPL from outperform to market perform and sets a $75 per share price target, with a 10-day window until new CEO Alex Chriss starts. Revenge of (MA) and (V).
• Jefferies reduces its rating for (PLNT) from buy to hold and lowers its price target from $90 to $56 per share following the sudden departure of its CEO. Other PTs are also cut after the CEO departure.
• Wedbush changes its rating for (CVNA) from underperform to neutral and increases its price target from $40 to $48 per share.
• BTIG raises its price target for homebuilder LEN from $148 to $161 per share.
• Some oil stocks, including (XOM) and (VLO), have had their price targets increased by Mizuho.
