Outperforming the Broader Market

Performance of Nasdaq Biotechnology Index (IBB) and S&P 500

Ongoing evolution of science, conquering medical frontiers, and saving lives, all makes the biotech industry an exciting one with the potential to create incredible value. At the same time, uncertainty, complexity, and volatility make biotech investing stressful and unnerving.

Nonetheless, the potential of the biotech industry in delivering incredible investment returns is real and it remains a key group in powering healthcare performance. 

There are unique attributes to the biotech industry that create the potential for outsized returns, but also higher risk. Such a unique risk (volatility) in a biotech investment comes from the binary nature of success or failure of the drug trials. This risk which is present in the biotech indexes is almost not present in an S&P 500 index, which is well-diversified across many industries.

Since the markets recovered from the 2008 Great Recession, biotechs have outpaced the general market quite convincingly.

However, the risk (volatility) encountered in a biotech investment will always be higher compared to an S&P 500 investment, which is well-diversified across many industries and does not have to face the binary nature of success or failure inherent in biotechs.

The chart shows the biotech industry delivering leading returns when compared to the broader market. Over a 12 year period from from 2010 to 2022, the Nasdaq Biotechnology Index (IBB) cumulatively returned 392%, while the S&P 500 (SPY) returned 286%. The volatility or standard deviation over the period was higher for the biotech index at 6.4 and 4.7 for the S&P 500. The risk-adjusted return using the Sharpe ratio was higher for the S&P 500 at 0.55 and 0.15 for the the biotech index.

Using Quantitative Models for Systematic Investing in Biotechnology

We matched the potential of biotechnology stocks with a systematic, model-driven investment approach.

The Prudent Biotech model portfolio uses quantitative models to further power
biotech performance and improve its risk-adjusted return profile.

We matched the potential of biotechnology stocks with a systematic, model-driven investment approach.

The biotech model goes through multiple iterations processing the quantitative parameters and rules for the biotech stocks and the broader market variables. The output is a list of high potential biotech stocks. 

We use our systematic investing methodology to select up to an 8-stock model portfolio that is shared with members in the monthly Prudent Biotech newsletter service.

The Prudent Biotech focuses on total portfolio returns and not on individual position returns. 

Stocks can go up and down within a portfolio. 

But it is the total portfolio return that must be the focus. 

It is hard to avoid losses on individual positions. For biotechs, such losses are even steeper due to the binary nature of the trial results. But through prudent risk management, the portfolio will likely have more positions that gain over time to offset such losses.

outpacing benchmark performance in most years

Performance of Nasdaq Biotechnology Index (IBB), S&P 500, and the Prudent Biotech model portfolio

In the chart above, we overlaid the performance of the Prudent Biotech portfolio along with the performance of the biotech industry group and S&P 500 that was shown in the first chart.

The quantitative models took a strongly performing biotech industry group and created a promising model portfolio that delivered compelling results in most years to far exceed the performance of the Nasdaq Biotechnology Index (IBB) and the S&P 500.

During the same period from 2010 to 2022, the model portfolio significantly outperformed with a gain of nearly 9,000% as seen in the chart above. Benchmark returns were much lower. The volatility for the Prudent Biotech portfolio was higher than the biotech index, but had a superior risk-adjusted performance. The Sharpe ratio for the model portfolio was 0.55 compared to 0.1 for IBB, indicating the higher-risk was compensated for in terms of returns. Additional metrics are provided in the Performance section.

The model portfolio focuses on generating consistent and robust returns through a disciplined investment approach. This approach combines various dimensions, including process-oriented strategies, market direction analysis, and rules-driven quantitative models that utilize fundamental and technical variables. By blending these elements, the model portfolio attempts to consistently deliver returns that outperform benchmarks in most years.

The power of compounding is an integral part of the approach which leverages the enduring strength of the stock market over the long-term and the magic of compounding to build wealth over time.

Investing in biotechs should be one part of a broader portfolio strategy. Longer term portfolio allocation to growth and speculative segments, like biotechs and small cap stocks, can achieve much higher risk-adjusted performance.

The Best Time to Plant an Oak was 20 Years Ago.
The Next Best Time is Now...

This is an old English proverb.

After all, one has to start somewhere at sometime.

There is no guarantee of future performance. That is true for our system and for any system.

Nonetheless, there is a strong and large body of empirical evidence that bolsters the thesis that systems outsmart experts consistently by a meaningful margin.

If you feel our system can help grow your portfolio over time and build the investment wealth that you wish for, then don't wait!

The Decision is yours now.

We leave you with a pragmatic quote from Warren Buffett,

While there is no one best system, there is one that works best for you. Once you choose a system, you need to stick with it.
