Stock Selection and The Logic Matrix
My Stock Selection Strategy
My stock selection strategy (for growth stocks, not long-term value stocks) is a hybrid of the systems described in the books that I have mentioned already, including those by William O'Neil, Martin Zweig, and Peter Navarro. In a nutshell, my philosophy of stock selection is: An outside player in a zero-sum game like the stock market, cannot afford to not use every available advantage, within the limits of legal market conduct. To that end, most of the stocks that I buy are discovered first in the Stock Scouter Top 50, on the Validea and AAII Martin Zweig Screens, and on the IBD 100. A stock must appear on one or more of my screens, and must rate well on either the IBD stock checkup or the Stock Scouter rating system (or preferably both), to be a candidate for purchase. I also have a few 'hard' requirements such as a lack of significant insider selling and a ROE of at least 12. .
I screen out most stocks from consideration because I only look at the strongest candidates at any time. I don't rely exclusively on any screen or rating system, but I run any purchase candidate through a thorough set of tests before I make a purchase.
For example, last week, although still in a defensive mind-set, I bought two stocks: SMTS and LCAV. These stocks first came to my attention on the Stock Scouter Top-Rated Technical and Stock Scouter Top-Rated Ownership screens, and also recieved very high marks from the IBD stock checkup. As an additional plus, these stocks are in the medical sector, one of those recommended for the late-bull/early-bear phase of the market (where I still believe we find ourselves) in If it's Raining in Brazil, Buy Starbucks, (Chapter 14, figure 14-1. Note that the stock and business cycle are mis-labeled in the legend in some editions).
On a less quantitative level, I like Somanetics (SMTS) because of their innovative products: brain oxygenation equipment for head injury victims, and cardiac repair patches. I like Lasik Vision Centers (LCAV) because they stand to benefit from the multitudes of baby boomers who will prefer laser-eye surgery to wearing glasses.
Another reason for purchase is that both of these stocks also appear to be undervalued, using metrics such as discounted cash flow and the Ben Graham fair P/E rule. Many traders ignore valuation, but it is my opinion that a stock with strong financial and stock price momentum is even more attractive if it is selling at a discount to its intrinsic value. I am not a stickler about valuation, but I do take it into account.
Also, I always set stop-losses on any short-term trade to ensure that my downside risk is strictly limited. A stop-loss can be frustrating if it is triggered and gets you out of a trade just before the stock rockets to new highs, but stop losses are crucial risk-management tools becuase they protect you from catastrophic losses. In many cases, you can offset your risk better by buying put options on the stock that you own to eliminate risk without the risk of being shaken out of a trade, but that is a topic for another column.
One of the best bits of advice that I have read regarding trading is that you should "enter a trade on ANDs, but exit a trade on ORs". So, to buy a stock, I must see accelerating earnings/revenue growth, a reasonable P/E, positive or neutral institutional and insider activity, an uptrending market, relative strength, etc. To exit a trade, a violation of my stop loss or deterioration of any of the primary reasons for making the buy decision is sufficient.
To trade this way, you must make some decisions and record those decisions before executing a trade. You must decide why you are buying the stock, what you will do if it drops X% from your purchase price, and what other conditions will be grounds for sale. If you do not make these plans and put them in writing, you are likely to fall prey to wishful thinking when your stock starts to fall, and you will start grasping for straws to provide a reason to hold your stock as it declines below your purchase price. I look at any trade as a complicated and inherently risky operation, which only has a probability of succeeding if I plan my operation carefully, and then execute that plan with minimal improvisation.
The Logic Matrix
Having discussed the fundamental and technical timing systems that I employ in my previous post, now I will explain how I combine these systems to determine how much market risk to expose myself to. I should note that this system changes directions fairly rarely - every few months. I combine the indicators described in my previous post to determine if the technical and fundamental indicators for the market are either weak, neutral, or strong. I then cross-index these indicators in a simple 9-cell table that I call The Logic Matrix, which dictates my target cash allocation and may also indicate certain temporary changes to my strategy. The Logic Matrix is posted at the bottom of this blog.
Between the beginning of January and the end of last week, The Logic Matrix put us in sector 4 (at the time, the weak uptrend was countering a longer-term downtrend, giving a neutral- technical rating). Now that we had a strong 4% buy signal last week on an unweighted S&P500 index, combined with other strong technical indicators, we are now in market sector 7, which indicates that I should shoot for a 20% cash position in my brokerage and 401(k) accounts.
To this end, on Monday I moved most of the cash in my 401k account into an even larger position in Fidelity Contrafund (FCNTX), and a smaller position in Artisan Midcap (ARTMX). Both funds have above average returns with average or low risk, as measured by Morningstar, and have held above their 200-day moving averages during the recent market choppiness. My strategy is to limit risk through both cash (or in the right circumstances, bond) allocation and investment vehicle selection. I consider it to be safer to concentrate funds in historically safe (good 10-year performance) funds than it to broadly diversify among funds with variable risk profiles, especially when market risk is high. Since both FCNTX and ARTMX have good long-term and short-term price stability and performance, they present the lowest risk options for increasing my exposure to market gains while keeping a leash on my exposure to market risk in these uncertain times. I have my doubts about the strength of the current rally.
FCNTX is the safest of the funds available to me, so why put any money in ARTMX? Because ARTMX is well positioned, in my opinion, to ride the leading sectors of the current rally which are tech, biotech and retail - Artisan is overweight in these sectors by a significant margin. In contrast, Rydex Low-Priced Stock fund (RYLPX) and ING International Value (NIIVX), two of my largest fund holdings last year, broke below their 200-day moving averages in the last few months and have yet to make a decisive recovery. These funds were very good to me last year, and I may purchase them again, but I am glad that I dumped them at the beginning of 2005 in favor cash and an overweight position in FCNTX. Note that I still keep a hundred dollars in each of these funds even after I "dump" them as a 'foot-in-the-door', ensuring that I have the option to re-enter these funds if they become closed to new investors. The mutual fund companies don't like this sort of activity, but they tolerate it as long as your major moves are more than a month apart.
In addition to determining my target cash allocation for my brokerage and 401k accounts, The Logic Matrix suggests certain refinements of strategy depending on the market situation. Here are a few of the important strategic and psychological considerations that come into play in each sector of The Logic Matrix:
- Tech Weak, Fundamentals Weak: Consider shorting, buying puts on weak rallies. Guard against dispair, and look for an excess of pessimism or other signs that the market is ready to reverse direction. Remember that, by definition, a bottom will occur when it is least suspected by the largest number of market participants. Remember that when a bull market starts, it will likely 'Climb a wall of worry'
- Tech Weak, Fundamentals Neutral: Watch closely for the fundamental picture to resolve itself as either strong or weak. Watch closely for the start of a rally.
- Tech Weak, Fundamentals Strong: If the market P/E has fallen very low, as it usually does at the bottom of a bear market, then this is the ideal time to buy excellent companies at excellent prices, according to the method laid out in The Warren Buffett Way. These companies are often in the sector that led the rally, which is now undervalued as a result of the fear of losing money in that sector. For example, in 2001 and 2002, stocks like EBAY and AMZN actually became undervalued for a time. Remember that strong fundamentals can occur in a recession in the form of slowing earnings deceleration and bullish monetary policy. The last time the market was in this sector was 2002.
- Tech Neutral, Fundamentals Weak: Favor defensive positions that generally weather weak fundamentals well. Dividend-paying stocks in reliable industries should be favored.
- Tech Neutral, Fundamentals Neutral: Be on alert for any indication of shifts in the fundamental or technical picture. The market rarely stays in this sector for very long.
- Tech Neutral, Fundamentals Strong: Favor value-and-growth strategies, and stay away from more speculative companies until the technical picture strengthens.
- Tech Strong, Fundamentals Weak: Buy growth companies in defensive sectors, and be aware that you are skating on thin ice in this sector of the Logic Matrix.
- Tech Strong, Fundamentals Neutral: Exercise normal caution, and favor momentum screens for stock picks. Keep a close watch on the fundamental picture.
- Tech Strong, Fundamentals Strong: Use wider stop-losses to let profits run. Consider buying calls on low-volume market sell-offs. Consider buying stocks with weaker fundamentals that are experiencing strong momentum. Guard against euphoria, and look for an excess of optimism or other signs that the market is ready to reverse direction. Be expecially vigilant about any sign of a deterioration in the Technical or Fundamental picture, so as to avoid joining the majority of investors who are caught off-guard. Remember that when the bear market starts, it will likely 'descend a slope of hope'.
Next week, I will discuss some key points and links on the subject of behavioral finance, the field that studies the many mind-melds, nerve-pinches, and other subtle cash traps that await investors in the stock market. The existence of these traps is part of the reason that many investors achieve the best results with a buy-and-hold technique.
- Logic Matrix: Sector 7 (Technical Strong, Fundamental Weak).
- Technical Sensors: O'Neil and Zweig 4% indicators are strongly positive, though we do have some resistance ahead around the Dow 10600 level. MA analysis continues to suggest intermediate-term risk, although if the indices continue to hold above their key support/resistance levels of SPX 1180, DJIA 10400 and Nasdaq 2020, which all three indices crossed and closed above last Wednesday, then the MA analysis will switch to positive. The 4% indicator is issuing the first buy signal this year on a broad move in the unweighted SP500.
- Fundamental Sensors: "This is without a doubt the most manipulated economy in recent history." I could not have put it any better myself. Also, rational reasons to be defensive still abound. As Peter Navarro mentions in his latest weekly commentary, the market seems content to ignore serious economic issues for the moment. So the question is: are the fundamentals better than they seem, or is the market having a bout of excessive optimism? The economic reports due this week might help to answer this question.
- Evaluation of Market Sensor Readings: Cautious and 20-25% in Cash. I have increased my market exposure in response to an improving technical picture, but I am sticking with relatively defensive mutual funds to minimize market risk.
