*** Gemini
This is a well-structured and informative article on spotting market plunges. Here's a review with some suggestions for improvement:
Overall Strengths:
Clear and Concise: The article is easy to understand, even for those who might not be deeply familiar with financial jargon.
Actionable Advice: It provides concrete "hints" or indicators that readers can use to make more informed investment decisions.
Practical Examples: The use of examples like the 2000 and 2008 market plunges, and how the SMA-350 strategy performed, makes the concepts more tangible.
Balanced Perspective: The author acknowledges that no method is foolproof and emphasizes the importance of risk tolerance and continuous learning.
Emphasis on Risk Management: The idea of "cheap insurance" and not moving all assets to cash at once are valuable takeaways.
Helpful Resources: The inclusion of links to Yahoo!Finance and the mention of Fidelity and StockCharts.com provide practical avenues for readers to apply the strategies.
Modern Relevance: The section on AI (ChatGPT, DeepSeek, Gemini) as a "second opinion" is a timely and relevant addition.
Areas for Improvement/Suggestions:
Introduction Clarity:
The first paragraph states, "This chapter is longer and conceptually dense." While honest, it might slightly deter some readers. You could rephrase it to be more encouraging, e.g., "This chapter delves into powerful concepts that, when applied, can significantly enhance your investment decisions."
"The first hint—Technical Analysis—is the most important." This is a strong statement. While you elaborate on it, you might consider briefly explaining why it's the most important earlier, or perhaps soften the phrasing slightly if other hints are also crucial in combination.
Chart Display:
You mention, "The following chart is created by Yahoo!Finance. If it does not display well on a small screen, copy the following link to your browser to display it on your PC. http://ebmyth.blogspot.com/2013/05/ta-graph-for-spotting-plunges-chapter.html" This is a good workaround, but ideally, the chart would be directly embedded and responsive. If you're publishing this online, ensure the image is optimized for various screen sizes. If it's a print article, perhaps a higher resolution image is needed. The placeholder image in the provided text is blank, so ensure the actual image is present and clear.
"Eleven Hints" Numbering:
The article starts with "1. Technical Analysis (TA) — The Most Important Indicator" but then jumps to "2. Follow the Flow of Money" without a clear "1." for the first hint. It seems like "Technical Analysis" is the first hint, but the numbering is a bit off in the provided text (there's a blank space where "2." should be after the chart, then "3. Market Cycle Duration"). Ensure the numbering is consistent from 1 to 11.
"Note that today’s valuations are influenced by low borrowing costs and globalization."
"I shifted to traditional sectors in early April 2000—barely ahead of the crash. I did well in oil in 2007 but took losses in 2008 across the board."
These personal anecdotes are good for building credibility. You could consider adding one or two more brief, impactful personal examples throughout the article if appropriate, to illustrate the application of other hints.
"As of Oct. 15, 2018, yields were nearly equal—suggesting caution."
Since the current date is July 13, 2025, this specific date reference for the yield curve inversion might feel a bit dated to a reader. You could either update this example with more recent data if available, or phrase it more generally, e.g., "Historically, when yields are nearly equal, it suggests caution."
"Links: Market crash https://www.youtube.com/watch?v=GJD2BYhVyrM 6 Signs of market crash https://www.youtube.com/watch?v=ynCXHgeZ_K8"
These links are to googleusercontent.com/youtube.com/0 and googleusercontent.com/youtube.com/1. While these are valid YouTube URLs for the model, they are not user-friendly and would not work if copied directly into a browser. You should replace these with actual, human-readable YouTube URLs (e.g., https://www.youtube.com/watch?v=VIDEO_ID).
"Sidebar: Related articles" and "Sidebar: The Cheat Sheet of market timing"
"Artificial Intelligence such as ChatGPT, DeepSeek and Gemini"
Overall, this is a strong article with valuable insights for investors. Addressing these minor points will further enhance its clarity, relevance, and impact.

*** ChatGPT
Excellent work overall—this is a strong, practical chapter with clear, actionable content. You share both personal experience and specific metrics readers can use immediately. That makes it genuinely useful.
Below I’ll give you (1) general feedback on strengths, (2) high-level suggestions for improvement, and (3) detailed, line-level editing suggestions.
1️⃣ Strengths
✅ Practical and specific — SMA-350, PE levels, yield curve rules. Readers will appreciate this level of detail.
✅ Personal credibility — You share what worked/failed for you.
✅ Balanced tone — You admit limitations (“educated guessing,” “no guarantees”).
✅ Organized — Eleven clear hints, plus cheat sheet and sidebars.
✅ Educational — You don’t oversell, you warn about false signals.
This is genuinely the kind of writing that readers of investing books trust.
2️⃣ High-Level Suggestions
Here are some things to consider for polishing:
✅ Be more consistent in style and formatting.
For example:
✅ Avoid minor clutter and redundancy.
Some places repeat the same idea twice.
✅ Tighten for readability.
A few sentences are long and can be split.
✅ Minor typos and grammar.
Example:
✅ Clarify links and callouts.
Your chart link instructions could be simpler. Your YouTube links could be cleaner.
3️⃣ Detailed Suggested Edits
Below I’ll show line-level revisions with sample rewrites. You can adopt them wholesale or selectively:
📌 INTRO
This chapter is longer and conceptually dense. You’ll get the best results by applying these ideas yourself.
✅ Suggestion: Slightly simpler.
This chapter is longer and conceptually dense. You’ll get the best results by actively applying these ideas.
No single method can predict market cycles perfectly, but combining the following hints increases your odds of making better decisions.
✅ Suggestion: Slightly tighter.
No single method predicts cycles perfectly, but combining these hints improves your odds of better decisions.
The first hint—Technical Analysis—is the most important.
✅ Optional: consider making that really clear, e.g.:
The first hint—Technical Analysis using the 350-day SMA—is the most important.
📌 PURPOSE
No one can consistently call every market top or bottom. This chapter is for educational purposes. But if our guesses are more right than wrong over time, we’ll do well.
✅ Slightly smoother:
No one can consistently call every top or bottom. This chapter is for educational purposes. If our guesses are more right than wrong over time, we’ll do well.
📌 GOAL STATEMENT
Avoid buying stocks during these plunges, which often last more than a year—from market peak to market bottom.
✅ Alternative:
Avoid buying stocks during these plunges, which often stretch over a year from peak to bottom.
The methods here aren’t foolproof, but they’ve worked well for me in past cycles.
✅ Alternative:
These methods aren’t foolproof, but they’ve served me well in past cycles.
📌 SMA-350 SECTION
350 days simple moving average (SMA). Yahoo!Finance
✅ Suggestion: Standardize to:
350-day Simple Moving Average (SMA) example from Yahoo! Finance
Example:
• Exit: Q1 2000 | Re-enter: Q1 2003
• Exit: Dec. 2008 | Re-enter: July 2009
✅ Consistency:
• Exit: Q1 2000 | Reenter: Q1 2003
• Exit: Dec 2008 | Reenter: July 2009
While no indicator is perfect, the SMA-350 often limits large losses. Think of it like insurance—it may cost you some gains, but can protect you when it matters most.
✅ Cleaner:
While no indicator is perfect, the SMA-350 often limits large losses. Think of it like insurance: it may cost some gains but can protect you when it matters most.
Note: I now use Fidelity for charting as Yahoo! sometimes has limitations.
✅ Optional, more neutral:
Note: I now prefer Fidelity for charting, as Yahoo! Finance has some limitations.
📌 SECTION HEADINGS
✅ Consider standardizing:
Example:
2. Follow the Flow of Money
3. Market Cycle Duration
Some headings lack colons or capitalization consistency.
📌 CLUTTER
Rising equity inflows and retail frenzy are also strong contrarian indicators.
✅ Simpler:
Rising equity inflows and retail frenzies are strong contrarian indicators.
I call this Newton’s Law of Investing: what goes up must eventually come down.
✅ Optional: clarify that it's your phrasing:
(What I call “Newton’s Law of Investing”: what goes up must eventually come down.)
📌 VALUATION METRICS
Note that today’s valuations are influenced by low borrowing costs and globalization. Always adjust expectations to the current macro context.
✅ Could be:
Keep in mind that today’s valuations reflect low borrowing costs and globalization. Always adjust expectations to the current macro context.
📌 BUBBLE TRIGGERS
Following these hints back then would’ve saved me a lot.
✅ Smoother:
Following these hints back then would have saved me a lot.
📌 INTEREST RATES
Watch for spikes in margin debt and Fed discount rates above 5%. These usually precede a downturn. Conversely, a rate below 1% may mark a market bottom—time to consider re-entering equities.
✅ Possible split for clarity:
Watch for spikes in margin debt and Fed discount rates above 5%, which usually precede downturns. Conversely, a rate below 1% may mark a market bottom—time to consider reentering equities.
📌 YIELD CURVE
As of Oct. 15, 2018, yields were nearly equal—suggesting caution.
✅ Clarify if this is historical example:
(For example, on Oct 15, 2018, yields were nearly equal—suggesting caution at the time.)
📌 POLICIES
Pay attention to macroeconomic levers.
✅ Maybe more direct:
Always watch macroeconomic levers.
📌 BE CONSERVATIVE
Start small. Don’t risk your entire portfolio based on new strategies—especially from a book you paid $25 for.
✅ Friendlier:
Start small. Don’t risk your entire portfolio on new strategies—especially those from a $25 book.
📌 CONCLUSION
If they were, everyone would be rich.
✅ A touch less casual if you want:
If they were, everyone would be wealthy.
