In the fast-moving world of algorithmic and quantitative trading, success is not just about coming up with a smart trading idea. It largely depends on how you handle risk, divide your capital, and decide the size of each trade. This is why portfolio position sizing is so important, especially for beginners who are moving from classroom learning to actual market experience.
Whether you are a student, changing careers, or starting out as a new quant, learning this skill early can be the difference between running a steady, profitable strategy and watching your capital disappear because of poor money management.
Automated trading for beginners from Quantra by QuantInsti, a well-known global platform for those starting out in automated trading. With live sessions, guidance from experts, coding practice, and career support, Quantra’s clear and practical training helps you go beyond just understanding the idea, it teaches you how to apply it with confidence in both real and practice markets.
What is Position Sizing and Why It Matters
Position sizing means deciding how much of your money to put into a single trade or spread across different trades. Instead of just figuring out “what to trade,” it focuses on “how much to trade,” which directly affects your portfolio’s losses, ups and downs, and ability to grow over time.
For someone new to quant or automated trading, this is not just helpful; it is vital. If your trade sizes are too big, even a strategy that wins often can cause huge losses because you are taking on too much risk. On the other hand, if your trades are too small, you might end up with weak returns and missed chances to grow your account.
Common Pitfalls Without Position Sizing
- Overtrading: Placing trades with excessive capital can result in rapid losses.
- Underutilization: Allocating too little reduces profit potential.
- Lack of Diversification: Improper sizing leads to overconcentration in certain assets or strategies.
- Poor Risk Management: No clarity on maximum loss per trade exposes you to systemic risks.
These issues are why learning platforms like Quantra integrate quant investing course and portfolio position sizing as core subjects in their courses.
Learn by Doing: The Quantra Advantage
One of the best parts of Quantra’s courses is the “learn by coding” approach. Instead of only reading or watching videos, you actually write the code yourself using Python right in your web browser, with no software setup needed.
Some courses are free for beginners, so you can start learning without spending any money. As you move forward, the flexible course design lets you pick topics and a pace that match your interests and time.
You can begin with simple courses like “Stock Market Basics” or “Python for Trading: Basics,” and then work your way up to advanced topics such as volatility targeting, using machine learning in finance, and factor investing.
A Closer Look at Quantra’s Portfolio Management and Position Sizing Track
The 66-hour Portfolio Management and Position Sizing track is designed for those who want to move from basic trading to advanced capital allocation techniques using quantitative methods.
Key takeaways from this course include:
- Optimizing trade size using techniques like Kelly Criterion, volatility targeting, and risk parity.
- Using machine learning models such as LSTM and Hierarchical Risk Parity (HRP) for portfolio allocation.
- Hands-on practice with live market paper trading, backtesting using Monte Carlo simulations, and applying unconventional alpha factors like skewness.
- Building both long-only and long-short portfolios using mean-variance optimization and other factor-based methods.
You don’t just learn, you apply. And with everything integrated into the course interface, there’s no setup friction.

- Market fundamentals
- Core strategies like event-driven, ARIMA, GARCH, and statistical arbitrage
- Hands-on tools for backtesting and strategy evaluation
- Basics of Python, data handling with NumPy and Pandas, and database querying for financial analysis
This track is beginner-friendly and doesn’t require prior coding experience. Several entry-level courses within this track are free, making it an accessible entry into quant finance.
Real Results: What Learners Are Saying
Meet Megan Lester, a student of Biochemistry at the University of Bristol, who discovered Quantra through social media. With only a fragmented knowledge of Python, she enrolled in the beginner track and soon found herself confidently applying programming skills to trading models.
“The coding exercises were my favorite part! They made me remember the code by actually writing it. I started to see how Python can be used practically in finance.” – Megan Lester
She has now moved on to more advanced courses like ‘Python for Machine Learning in Finance’, proving that even non-finance students can become confident with quantitative trading tools.
