What Should Investors Do Now

So, what does this all mean for investors? Most importantly, this is a tactical market reset, not a call to abandon equities and go hide in cash. Scott Rubner himself framed the September weakness as a “better entry point ahead of a more constructive mid-October.”

He is correct. Once mid-October arrives, the options expiry will have cleared, the FOMC will have met, and corporate buybacks will have resumed. Notably, the market will be focusing on Q3 corporate earnings reports. which typically support markets heading into November.

Therefore, the investor playbook is to use market strength to rebalance portfolio risk rather than chase it.

Heading into next week, the support and resistance levels are evident. The first resistance is the record at 7,796, about 1% away. Just above that are the round numbers at 7,900 and 8,000. (Those are our year-end targets that sit just above previous all-time highs.) Conversely, support starts at the 50-day near 7,585. That level also marks the breakout that a failed retest would expose. Just below that level is the 7,300 zone, then the 200-day at 7,137, the same downside band the seasonal math points toward.
