Weekly SPX Outlook ending Sep 08:

SPX 4500 still remains the key crucial support area. We saw today Sep 01 how they brought it down to 4501 and held it all day. Short week next week so we could FULLY expect to see a move back up to 4525-4530, over that 4550 then 4580-4600.
Under 4500 fully expect to see 4480 get contested. Below that don't expect and support until 4450 then 4420 and POSSIBLY 4400.
