2. Recession Risk
• Recessions are strongly associated with market drawdowns;
8 of 10 bear markets have occurred during recessions.
• According to the National Bureau of Economic Research, the
last recession began in February 2020, at the start of the
pandemic, and ended soon thereafter.
• The economic expansion continued in September, with strong
hiring serving as a highlight. The primary risks are a deeper
slowdown in growth and tighter monetary policy from
the Fed.

3. Economic Shock Risk
• A major systemic risk factor is the price of money, otherwise known
as interest rates.
• Interest rates drive the economy and financial markets; historically,
they’ve also played a key role in market downturns.
• So, let’s take a closer look at the yield curve.

5. Yield Curve (10-Year Minus 3-Month Treasury Rates)
continued
• The yield curve inversion narrowed in September. The
3-month yield fell from 5.56% at the end of August to 5.55%
at the end of September. The 10-year yield increased from
4.09% to 4.59%.
• This now marks 12 consecutive months with an inverted
3-month 10-year yield curve. This doesn’t guarantee that the
economy will enter a recession, but this widely monitored
signal could indicate further slowdowns.

6. Market Risk
• Beyond the economy, we can also learn quite a bit by examining the
market itself. For our purposes, two things are important:
1. To recognize which factors signal high risk
2. To try to determine when those factors signal that the risk
has become an immediate concern
• Here, we’ll review valuations, margin debt, technical factors, and
market complacency.

continued
• Looking at the 10-month change in the Shiller cyclically adjusted
price-to-earnings ratio is a good gauge of immediate risk.
• When the change drops below zero over a 10-month or
200-day period, the market typically drops shortly thereafter.
• On a 10-month basis, valuations rose 8.56% in September.

consecutive months of declining year-over-year
margin debt.

Moving Averages continued
• We start to pay attention when a market breaks through its
200-day average; a breakthrough of the 400-day average
often signals further trouble ahead.
• The S&P 500 and Nasdaq Composite finished above their
respective 200-day moving averages in August, while the Dow
Jones Industrial Average finished the month below-trend.

14. Market Complacency: S&P 500 Forward P/E
Divided by VIX continued
• Often, high valuations (forward P/E) signal investors are confident
and potentially complacent. When volatility (VIX) is high, there is
less complacency.
• Periods of high valuations and low volatility cause peaks in the
index (e.g., 2000, 2006–2007, and 2017); market drawdowns
occurred roughly one year after those peaks.
• Market complacency increased modestly in September. The VIX
fell from 15.85 in August to 15.24 in September, while the
forward-looking P/E ratio dropped from 18.6 to 18.1.

15. Conclusion: Risks Remain for Investors
• The continued sell-off in September was a reminder that real
risks remain for investors despite the positive returns we’ve seen
year to date.
• Rising rates and political dysfunction served as headwinds for
investors during the month.
• Ultimately, the path back to normal will likely be long, with
setbacks along the way.
