Deepseek summarizes the trading system of "Stock Selection Code"

Little Peach's Study Notes February 13, 2025 05:25

Summary of the Stock Market Miracles Trading System

The Stock Selection Code was written by Valas Voss, a disciple of William O'Neil. It combines the concepts of growth stock investment and momentum trading, and proposes a stock selection framework centered on "earnings acceleration + technological breakthroughs" to capture the rapid rise of explosive performance stocks. The following is a summary of its core trading system:


1. Stock selection logic: profit acceleration and supply-demand resonance

(1) Fundamental screening: profit acceleration

  • Quarterly profit growth rate : Net profit growth rate of ≥30% year-on-year for two consecutive quarters, and the growth rate increases quarter by quarter (e.g. Q1 30% → Q2 40%);

  • Revenue growth verification : Revenue growth rate ≥ 20%, excluding profit growth driven solely by cost reduction;

  • Profitability indicators : ROE (return on equity) ≥ 15%, gross profit margin ranks in the top 20% of the industry;

  • Industry status : Leader in a specific market segment, with pricing power for products or services (such as CATL in the field of power batteries).

(2) Technical confirmation: momentum and pattern

  • Relative Strength (RS) : The stock price ranks in the top 10% relative to the market (RS Rating ≥ 90);

  • Compact base : the stock price adjustment range is ≤30%, the adjustment time is 3-8 weeks, and the trading volume shrinks to less than 50% of the peak value;

  • Breakthrough signal : Breakthrough of the base high point with large volume (trading volume ≥ 1.5 times the 5-day average volume).


2. Buying strategy: accurately capture the main rising wave

(1) Three major buying points

  1. First breakthrough of base :

    • The price breaks through the high point of the adjustment range, accompanied by a significant increase in trading volume;

    • Case : In 2020, BYD broke through the 60 yuan platform and then rose to 200 yuan in the following six months.

  2. Retracing to support level :

    • After the breakthrough, the volume shrinks and falls back to the original resistance level (now support level), and the position is increased after the validity is confirmed;

    • Case : Kweichow Moutai broke through 500 yuan in 2017 and then fell back to the 10-week moving average.

  3. Performance forecast exceeded expectations :

    • The stock price opens higher after the earnings announcement, and if the gap is not filled within 3 days, intervene;

    • Case : WuXi AppTec’s net profit in Q1 2021 exceeded expectations, jumping 30%.

(2) Position management

  • Initial position : 10%-15% of a single stock to avoid over-concentration;

  • Pyramid position increase : increase the position after the profit reaches 5%-10%, and the total position shall not exceed 25%;

  • Stop-loss discipline : Exit the market immediately if the price falls below the lowest price of the buying K-line or the support level by 5%-7%.


3. Selling rules: lock in profits and avoid risks

  1. Technical profit-taking signals :

    • The stock price plummeted in a single day (the decline was ≥7%, and the trading volume hit a recent high);

    • The relative strength (RS) fell below the 70th percentile (bottom 30% of industry ranking).

  2. Signals of deteriorating fundamentals :

    • The quarterly earnings growth rate slows down (e.g., the growth rate in Q3 drops below 20%);

    • Gross profit margin has declined for two consecutive quarters or accounts receivable has surged.

  3. Systemic risk response :

    • The market index falls below the 50-day moving average and the trading volume shrinks, and the position is reduced to less than 50%;

    • When industry leading stocks collectively break through, clear out your positions and wait and see.


4. Risk management and psychological control

(1) Risk control rules

  • Single risk limit : Single stock loss does not exceed 2% of total funds;

  • Diversified allocation : holding 5-8 stocks covering 3-5 different industries;

  • Volatility matching : The proportion of positions in high-volatility stocks (such as technology stocks) is lower than that in low-volatility stocks (such as consumer stocks).

(2) Trading psychology

  • Refuse to "spread the cost" : do not add to losing positions and avoid emotional decision-making;

  • Isolate market noise : reduce the frequency of watching the market and execute transactions as planned;

  • Regular review : monthly statistics on win rate, profit and loss ratio, and optimization of buying and selling point rules.


5. Uniqueness of the system

  1. Prioritize profit acceleration : Emphasize the “quarter-by-quarter improvement” of quarterly profit growth rather than simply high growth;

  2. Compact Basis Model : Filter false breakthroughs by adjusting amplitude and time to improve the winning rate;

  3. Industry rotation strategy : give priority to industries driven by "profit acceleration + policy catalysis" (such as photovoltaics in 2021 and AI computing power in 2023);

  4. Practical case verification : CATL (2019-2021), Will Semiconductor (2020), etc. are in line with the profit acceleration and base breakthrough model.


Summarize

The trading system of "Stock Selection Code" is centered on "profit acceleration + technical momentum". It screens high-growth stocks through fundamentals, confirms the start of trends through technical aspects, combines strict risk control and industry rotation, and captures excess returns during performance explosion periods. Its success relies on:

  • Data sensitivity : timely discover profit turning points and changes in industry prosperity;

  • Discipline : Unconditionally execute stop loss and take profit rules;

  • Industry insights : Focus on sub-sectors driven by policy and technological innovation.

This system is suitable for short- and medium-term investors, but it requires high financial report analysis ability, chart pattern recognition and psychological quality. The core formula can be summarized as:
excess return = profit acceleration × technical momentum × risk control .

My Presentation and Travel Equipment | JosephGuadagno.net | Home office | Tips for home office

Here is the link. 

 7 minute read

This month in a chat with the speakers of ESPC one of the United States based speakers asked about some travel gear recommendations. I shared my travel gear with them and they found it helpful. I thought it would be a good idea to share it with you all. I have been using this gear for a while now and I am very happy with it. I hope you find it helpful too.

Presentation EquipmentPermalink

There are a few things that I always carry with me when I am presenting at a conference or a user group meeting.

Presentation ClickerPermalink

Presentation Clicker Air Mouse Function Wireless Presenter USB Powerpoint Clicker (only USB Receiver) for Laptop, Computer, Projector, Mac, PC (Amazon Link). This device has more features than just advance and reverse slides. It has a built-in laser pointer, air mouse function, media play, and more. It is very handy when you are presenting and you need to move around the room.

Extra MonitorPermalink

A lot of community conferences do not have “confidence monitors” for the speakers. I always carry a portable monitor with me. It is very handy when you are presenting and you need to see your slides. I use the Lepow Portable Monitor, 15.6 Inch Full HD 1080P USB Type-C Computer Display (Amazon Link). It’s lightweight and easy to carry. Plus I can use it as a second monitor when I am working from hotels.

Having a second monitor requires having an adapter to connect it to your laptop. The are two different cables to use with this monitor depending on the version you have. I have an older version that supports USB-C and mini HDMI. For this, I have this cable: Cable Matters High-Speed 4K Mini HDMI to HDMI Cable 15ft (Amazon Link). If you are purchasing the model linked above, you will need a USB-C to USB-C cable. I recommend the JSAUX 100W USB C to USB C Cable (Amazon Link). I keep a couple of these cables in my bag for data transfer and charging.

Presentation AdaptersPermalink

I never know what type of equipment I am going to be presenting on so I carry along a few different video “adapters” to accommodate different types of projectors. I use the USB C to HDMI Adapter, Tuwejia USB 3.1 Type C Thunderbolt 3 to HDMI 4K Adapter Compatible with MacBook Pro 2018/2017, MacBook Air, Samsung Galaxy S10 S9 S8 Note 9, Surface Book 2 and More (Amazon Link).

I also carry in my bag the Anker 332 USB-C Hub (5-in-1) with 4K HDMI Display, 5Gbps - and 2 5Gbps USB-A Data Ports (Amazon Link). This is a great adapter to have in your bag. It has a USB-C port, 2 USB-A ports, and an HDMI port. It is very handy when you need to connect multiple devices to your laptop or even power your USC-C laptop.

Presentation CablesPermalink

I always have a few different cables in bag:

Cable BagPermalink

This item took me a while to find the “right” one. I wanted something that was small enough to fit in my backpack but big enough to hold all of my cables. I found the BUBM Double Layer Electronic Accessories Organizer, Travel Gadget Bag for Cables, USB Flash Drive, Plug and More (Amazon Link). It is perfect for my needs. It has a lot of pockets and compartments to hold all of my cables and adapters.

Travel EquipmentPermalink

For travel, I have a few different items that I always carry with me. Here is a list of the equipment that I carry with me.

It has 3 charging pads, one for your phone, one for your watch, and one for your earbuds. I set it up in my hotel room when I get there to charge my phone, watch, and ear buds.

Since public speaking generally requires travel and you can not guarantee the quality of the power outlets on airplanes, trains, or at the venue, I always carry a portable charger with me. I use the 25800mAh Power Bank, 22.5w Fast Charging Battery Pack (Amazon Link). This charger is very handy when you are traveling. It has a 25800mAh battery capacity and can charge multiple devices at the same time. It is very handy when you are traveling and you need to charge your laptop, phone, and other devices.

Recently, I added trackers to all of my bags, including my laptop bag. Since I have an Android based phone, I added the Pebblebee Tracker Clip Universal - Rechargable Item Tracker (Amazon Link). This product works both with Android and iOS devices. It came in very handy on the return flight from Stockholm when my bags decided to extend their vacation and not come home with me. :smile: Pebblebee also has a card version of the tracker that I have in my wallet and large suitcases.

I primarily use a Dell laptop and it’s AC adapter has a “mickey mouse” style plug, or more technically known as an IEC 60320 C5 connector, to power the power brick. This makes it easy to find a replacement power cord when traveling internationally. I use the CableLeader 6ft Right Angle European 3-Prong Notebook Power Cord CEE 7/7 (Amazon Link). For the United Kingdom I use UK 3 Prong AC Power Cord Cable for Dell HP Asus Sony Toshiba Lenovo Acer Charger (UK Power Cord) (Amazon Link) .These power cords are very handy when you are traveling internationally.

nvidia stock delta exposure

 AI Overview

Nvidia's (NVDA) delta exposure (DEX) is an estimate of the dollar value of shares that market makers need to hedge for every 1% change in the price of Nvidia stock. 
How is delta exposure calculated? 
  • Delta exposure is based on the delta of an option, which measures how the price of an option changes in relation to the price of the underlying stock.
  • Market makers use delta hedging to maintain neutral market exposure.
  • When dealers have a positive delta exposure, they must sell the underlying stock to maintain neutrality.
  • When dealers have a negative delta exposure, they must buy the underlying stock to maintain neutrality.
How can I view Nvidia's delta exposure?
  • You can view Nvidia's delta exposure on OptionCharts.io. 
  • You can also view Nvidia's option chain, which includes delta, gamma, and other information, on Nasdaq.com. 
What does delta exposure indicate? 
  • The magnitude of the delta exposure indicates the strength of the potential buying or selling pressure on the stock.
