Systems To Lick The Market

Violent turns in the market, particularly when they result in lower prices, can cause a lot of consternation among investors. Extreme volatility makes folks feel understandably jittery. But there are ways to play the volatility, systems that those of the trading mind can use to exploit big ups and downs in stocks.
For evidence that volatility has been higher in recent months, just check out the CBOE Volatility Index--a measure of the premiums that options traders are willing to pay on S&P 500 Index options. Since February 2007, the VIX, which had been in a downtrend since October 2002, shot up and more than tripled--although it has settled back down to the mid-teens recently.
Higher VIX readings generally correspond to a higher level of fear in the market, and rather than get spooked by that volatility, there are systems traders can use to navigate it. We checked in recently with some market pros that offered a few systems traders can try, ways to make friends with volatility.
The first is the Moving Average Convergence Divergence (MACD), which has characteristics of both a trend following system and an oscillator. At its simplest, the MACD basically tells you what direction market momentum is going.
Most charting tools allow you to plot the MACD, which shows the difference between two moving averages of prices, typically a 26-day exponential moving average (EMA) and 12-day EMA. When the MACD gets below zero and turns upward, that can be viewed as a buy signal. If it gets above zero and turns downward, that then can be viewed as a sell signal.
Of course, there can be many switches in direction. The best MACD signals are confirmed by other chart patterns, says those who employ the system.
The system was first developed by Gerald Appel back in the 1970s. Appel was a psychotherapist by training who became interested in the stock market and wanted to develop an indicator that would allow him to trade mutual funds.
His son, Dr. Marvin Appel, now CEO of Appel Asset Management and editor of the investment newsletter Systems and Forecasts still uses the system his dad created. Dr. Appel, an anesthesiologist by training, likes to use the 12 and 26 MACD.
"The market can exhibit too much random noise for the MACD to be useful in a very short-term period, like intraday ticks," he says. "Conversely, using MACD in a monthly chart can sometimes be too slow in recognizing new trends. So 12 and 26 is a good compromise."
Appel says he doesn't do much short-term trading but, when he does, he uses the MACD to confirm attractive buying areas. He also uses a weekly MACD for trading investment grade bond ETFs. "There are significant intermediate trends that last weeks or months," Appel says. "MACD filters out the noise but gets the investor on the right side of major interest rate trends when there have been any.
Here is one pick Appel suggests: Bank of America (nyse: BAC - news - people ).
"I like Bank of America because it is one of the most solid of the financial institutions, having weathered the credit crisis relatively well so far," Appel says. "It pays a generous 6.7% dividend yield, which means that investors are getting paid very well while they wait for the financial sector to take off, which could be in another year from now. Its stock looks safe from the perspective of technical analysis."
Appel says the stock has shown strong support above $35 per share.This is confirmed by a bullish double rising bottom in the MACD. The recommended strategy, Appel says, is to buy BAC at $37.50 to $38.00 per share, and write $37.50 calls. "I think the June $37.50 or August $37.50 calls offer the best balance between the potential risk and reward of a covered call position." Another system you can think about using: timing the cycles of high and low dividend yields.
That's what Kelley Wright, editor of the newsletter Investment Quality Trends, practices. "Most simply, when a stock offers high yield, investment capital is attracted to it," Wright says. "When yield falls, capital flows out of the stock. Rather than emphasize price cycles of a stock or a company's products or strategy, the dividend yield theory stresses dividend yield patterns."
Here is what Wright does: First, he narrows down the universe of 13,000 stocks to a few hundred "Select Blue Chips" using a simple screen.
In order to make his list of potential picks, the company must meet at least five of the following six criteria:
--Dividend increases five times in the last 12 years
--S&P Quality ranking in the "A" category
--At least 5,000,000 shares outstanding
--At least 80 institutional investors
--At least 25 years of uninterrupted dividends
--Earnings improved in at least seven of the last 12 years
That screen leaves Wright with about 300 companies. From there, it's all about the dividend. A stock is in a buying area when the dividend yield is at the high end of its historical range. A high dividend yield is usually associated with a low price. A selling area is when dividend yield is historically low and the price is unattractively high.
What does this theory tell us about the current market? Overall, stocks in the Dow are decent buys right now with a dividend yield of 2.44%. According to Wright's theory, the Dow wouldn't be overvalued until its yield fell to 1.5%, which would correspond to a Dow level of 20,898.
Wright offers two picks for your consideration. First he likes Polaris Industries (nyse: PII - news - people ).
"Polaris sells fun," Wright says, "like snowmobiles and jet skis. The stock has declined a tad below its undervalued area. I suspect this is largely due to fears of recession and that the consumer would defer purchases of this kind of equipment. The key to our system is to buy a company like Polaris when its price is depressed and its yield is high. In this case, the current yield is higher than normal at undervalue."
Wright adds that if the Street starts to think a recession will be shallow or that we'll avoid one altogether, he see Polaris taking off.
Wright also likes the look of Procter & Gamble (nyse: PG - news - people ). He points out that the company has paid a dividend uninterrupted since 1891. Look at their dividend since 1999 when it was $0.57 and today at $1.60, he says. "That 300% increase in dividend income is why we buy stocks like Procter & Gamble."
A final system to consider: Bollinger Bands. This is the creation of John Bollinger, president of Bollinger Capital Management in Manhattan Beach, Calif.
Volatility used to be thought of as static, Bollinger says. "IBM's volatility, for example, was thought to be a fixed property of the stock. It wasn't thought that it changed over time. Betas, the basic measure of a stock's volatility, were calculated once a year. People weren't lazy. They just didn't think you needed to do calculations anymore frequently or results would be variable."
But volatility was actually much more dynamic, market pros discovered. The purpose of Bollinger Bands is to provide a relative definition of high and low. By definition prices are high at the upper band and low at the lower band.
"Traders can create systematic trading systems and test them and get a handle on what the results will be like," Bollinger says. "You are no longer making emotional decisions. You are waiting for systematic set-ups before making entry or exit decisions."
This tool isn't really for the casual stock watcher, but perhaps appropriate for a more experienced trader.
It's all about "how much you made when you were right" & "how little you lost when you were wrong"
