Workshop Portfolio A Diversified, Real-Life Portfolio

In the last few articles, I have discussed how to develop a stock portfolio using a variety of Mechanical Investing strategies. Today, we will look at this advice in real life by looking at a portfolio I started 18 months ago.

This portfolio was started on November 30, 1998. The portfolio is in an IRA account that was started with $250,000 at Fidelity Investments. Since inception all transactions on this account have been reported the day they occur on the Mechanical Investing board under the subject line "Real Money Port." The same reports have been put on the Foolish Workshop board since that board's inception. The money is that of a close relative of mine.

For this investor, the goal was to develop a diverse portfolio of strategies that outperformed the S&P 500. To do this I wanted a portfolio that included value stocks but put an emphasis on growth.

The portfolio consists of five strategies that began with equal amounts of money:

Value: A Foolish Four variation (Year 1: EY, Now: BTD4)
Large-cap Momentum: Keystone variations (Year 1: Keystone, Now: KeyEPS)
Large-cap Growth: Spark
Growth/Momentum/Value: PEG 26
Momentum: Relative Strength variations (Orig: RS-IBD and then RS-26, Now: RS-O)

From the list you can see I put 20% in pure value and then split the remaining 80% in both growth and momentum, further splitting that group into strategies that selected only large-cap stocks and those that take any size of stock.

I also wanted to have some diversification based on holding length. Based on the backtested performance of the strategies selected and my own bias to limit the number of trades (commissions), I set up three as annual strategies: Foolish Four, Keystone, and Spark. To get some short-term variation into the strategies, I renew the PEG strategy every quarter and the RS-O every month.

The only thing I left out was start date diversification. In those days I didn't realize the importance of such diversification, therefore all the five strategies used the same start date, the last Friday in November.

Eighteen months later this portfolio is a huge success. It is up 131.9% as of May 31, despite losing 24% over the last quarter. The 24% drop, while 3% lower than the drop in the Nasdaq over the same period, still shows that when investing in these strategies you have to be prepared to ride out some very volatile periods.

The results of the portfolio by quarter are shown below:

Strategy   Q1       Q2       Q3     
Dow30     0.07%   13.47%    5.02%
Nasdaq   15.27%    7.98%   11.67%
S&P500    4.50%    5.13%    3.57%
         
FF        0.92%   18.49%    0.76%
Key      25.79%   10.30%   10.57%
Spark    30.89%   -4.84%   14.44%
PEG      20.48%   27.96%    1.77%
RS       34.66%   29.55%   36.09%

Portfolio         
Total    22.55%   16.13%   13.96%

Strategy   Q4       Q5       Q6      Total
Dow30    -1.91%   -6.89%    3.89%   13.14%
NASDAQ   20.92%   40.78%  -27.59%   71.33%
S&P500    3.03%   -1.63%    3.97%   19.88%
            
FF        0.00%  -26.44%    4.36%   -7.52%
Key      23.93%   62.90%  -18.70%  151.76%
Spark    20.19%   16.27%   -2.04%   95.13%
PEG      57.64%   46.58%  -29.27%  156.42%
RS       12.87%  110.83%  -35.75%  263.01%

Portfolio            
Total    23.01%   52.97%  -24.03%  131.85%

Q1 = 11/30/98 to 2/26/99
Q2 =  2/26/99 to 5/28/99
Q3 =  5/28/99 to 8/27/99
Q4 =  8/27/99 to 11/30/99
Q5 = 11/30/99 to 2/29/00
Q6 =  2/29/00 to 5/31/00

You can see the big dog of the portfolio has been the Foolish Four, although it only lost money in one quarter. You can also see that the Foolish Four was the only strategy to perform well last quarter. The table also shows how the PEG and the RS strategies sometimes perform opposite of each other. Look at quarters 3 and 4 in particular.

You can see that a portfolio of strategies produced outstanding results. It even beat the Nasdaq every quarter, and it beat all three market indices overall and in five of the six quarters. Even with last quarter's high volatility, the returns were far less volatile than if I had just used one or two strategies.

Until next time, Fool On!
