Prudent Small Cap Service

Small Caps across industry groups up to
around $4 billion market cap

Small Cap Model Portfolio

The Prudent Small Cap (formerly Graycell Small Cap) model portfolio focuses on the universe of stocks from $200 million to up to around $4 billion in market capitalization. The investment focus is to participate in the early growth stages of a company while diversifying sufficiently across industries and the market cap range that includes small cap stocks (up to $3 billion) and early stage midcap companies, known as SMIDs (small midcaps). The return objective of the quantitative model-driven portfolio is to outperform the Russell 2000 over a 12-month period. Over its long history, the model portfolio performance has surpassed its objective quite convincingly in most years. The portfolio comprises up to 10 stocks that are about equally-weighted. The model portfolio was first published in 2003 as a weekly service and published for 7-years till 2009. It was then resumed from 2012 to 2015. Since 2016 the model portfolio is offered as a monthly newsletter service.

Investment Performance of Stocks, Bonds, and Bills - 1926 to 2021 (MorningStar, Ibbotson Associates, NY Life)

Financial instruments inevitably rise over time. Even inflation creeps higher.
Since 1926, a period of about 100 years, small cap stocks have materially outperformed the large caps.
If economic conditions are sound, small caps generally outperform due to a higher risk-reward. 

One can observe the power of compounding in the chart above.
Even a mere 2% differential in compounded return can lead to an exponential difference in $ returns,

(Results of small cap performance can be lower than large caps for different time periods)


Small caps are generally defined as stocks with a market capitalization (market cap) between $200 million and $3 billion. Such stocks are typically riskier than larger-cap stocks. The risks to small cap companies include less liquidity (lower volume of shares traded), less research-coverage compared to larger cap peers, greater sensitivity to unconfirmed market rumors or hearsay, less institutional sponsorship, and relatively limited access to financing options. However, the greatest opportunities for capital appreciation also lie in the small cap and early stage midcap stocks, principally because of their undiscovered nature. The key is to manage down the risk, since it cannot be eliminated, and find a blend of risk and reward that optimizes the risk-adjusted returns. We believe a wider market cap range that includes the relatively more stable SMID or smaller midcap companies can also contribute towards managing down risk and enhancing risk-adjusted returns. Consequently, the Graycell Small Cap Model Portfolio has a targeted market cap range of $200 million to around $4 billion.

The focus for the model portfolio is on generating consistent and strong benchmark-beating returns. This is achieved through a highly disciplined approach to investing combining a number of aspects including market direction analysis, rules-driven quantitative modeling using fundamental and technical variables, and being process-oriented. Overlaid on this investing approach is our belief in the Power of Compounding. Strong consistent returns boosted by compounding over the long-term can unleash tremendous portfolio growth over time.

Investors must use the enduring power of the markets and the magic of compounding to build long term wealth.

Small Cap Service Fit

High Risk and High Reward product
Generally appropriate for investors with a longer-term focus, who decide to allocate a portion of their portfolio to higher risk opportunities
Investors who are closer to retirement should generally consider a relatively smaller allocation to riskier products targeting small cap stocks and need to determine if a small cap sector exposure is beneficial to their investment plans
An investor must have at least a 2-3 year horizon to benefit from such systematic portfolio products with the objective to build investment wealth over time.
The most important thing is to have reasonable and realistic expectations from the stock market, which is a risk-reward and not a risk-free market.
The small cap portfolio is not insulated against losses, and we can try to manage risk but not eliminate it. Past performance is not indicative of future results.
We are in no position to comment on the suitability of the small cap service relative to your needs, risk tolerance and financial position. We are not a registered representative as defined by the SEC. Kindly consult your professional financial advisor.

 I had read your work on Seeking Alpha and subscribed to the Prudent Biotech and the Graycell Small Cap newsletters. Since 2017, it has worked out fabulously. 2022 has been an up-and-down year so far, but I believe staying the course is important. Thanks for the service and you've earned my renewals.

It's great. I started the Biotech and Smallcap services a few years ago and then added Healthcare when it came out. Never looked back. I am happy and being a broker, my clients are satisfied too.
