Summary We expand the discussion from a recent Editor’s Pick on building portfolios with the lowest volatility stocks in the S&P 500 Index. We point out that high beta is not necessarily high momentum and discuss why low volatility stocks might provide stronger performance. We simulate the portfolio construction calculations behind the S&P 500 Low Volatility Index and construct the current Top-10 portfolio holdings. We re-rank the lowest volatility stocks by momentum metrics to find stocks trending higher even in the current choppy market conditions. Introduction In a recent Editor’s Pick , Ploutos discussed the relative merits of using low volatility and high beta funds to generate better returns than the SPX (Ref 1). He combined the PowerShares S&P 500 Low Volatility Portfolio (NYSEARCA: SPLV ) and the PowerShares S&P 500 High Beta portfolio (NYSEARCA: SPHB ) to improve returns. His analysis is open to two criticisms. First, he was using a high beta portfolio as a substitute for a momentum strategy. However, high beta does not necessarily mean high momentum. Naturally, these terms are not cast in stone, and differences in calculation methodology and time period of data used in the analysis can change the measured beta as well as calculated momentum. So, for example, a fund like the PowerShares DWA Momentum Portfolio (NYSEARCA: PDP ) could be substituted for the SPHB portfolio. Second, he does not discuss why a stock may have low volatility, why a group of 100 stocks with the lowest volatility had returns greater than the full 500-strong index, and why this outperformance should persist for years on end. Thus, it is theoretically possible to go through a prolonged period during which the 100 stocks with the lowest volatility as a group do not consistently outperform the full index or their high-beta cousins quarter after quarter, and two groups flip flop back and forth negating any benefit of switching from one group to another. Why do stocks have low volatility? There are many reasons a stock could have low volatility. A stock may have low volatility because it has slow earnings growth and does not have the price amplitude, volume and spreads to catch the fancy of short-term traders. The stock may have large institutional ownership, and any dip in the stock leads to greater accumulation by institutions, so that large drops are rare. The earnings could be highly predictable and consistent, so the stock does not produce either positive or negative earnings surprises. The stock could have a large dividend payout, so it trades more like a bond than a stock. The stock could have gone through a period of very high volatility, that has shaken “weak longs” out of the stock, and volatility has diminished as the stock goes through a consolidation. A stock may be viewed as having a conservative management with high cash-flow, slow-growth businesses, that are not sensitive to strength or weakness in the economy. Hence, low volatility could be proxy for slow growth, high cash generators with large institutional ownership that are perceived as “low risk” investments. Thus, the exact reasons that a stock has low volatility over a given period and its implications for price advancement over the immediate future are unclear. Also, there could be numerous other reasons for low volatility in a stock. Why do low volatility stocks outperform the full index? In the ideal scenario, a stock has low volatility, is accumulated, and volatility increases due to favorable developments in the stock, such as improved growth prospects, and the stock breaks out into a strong trend. For example, management could focus on cutting costs and buying other companies with higher-margin products in the same sector. Thus, trading low volatility becomes a counter-trend entry into a stock that will morph into a growth story in the future. In this scenario, this stock starts off as a low volatility entity that shifts gears into a high growth phase, accounting for its outperformance. Of course, it will eventually drop off the 100-lowest volatility list, but then, its substitute will ideally repeat the same pattern. Alternately, the external market environment deteriorates, due to a weak economy or geo-political risks, prospects for price acceleration are murky or confusing, and money comes out of high-beta or high-volatility stocks and rotates into low-volatility stocks, being used as a temporary hedge or defensive position against market worries. These conditions could last for several quarters, and would again account for out-performance versus the full index. Naturally, there could many other possibilities for why low volatility stocks perform better than the index as a whole, such as buy-outs, rising dividends or a prolonged period of very low interest rates. Current State of Play: SPLV ETF As we have discussed above, low volatility does not have to mean low returns, especially when these stocks are used as a bulwark against market uncertainty. We perform a full trend analysis of the top-10 holdings of the PowerShares SPLV ETF (see Figure 1) below. The Top 10 are trending well, with good buying support for CB and BAX in particular.

(Data courtesy ETFmeter.com ) Updated Holdings through August 6 We asked the question: what would the current top 10 look like? We copied the methodology of the index and our updated top-10 holdings are shown in Figure 2. From Figure 1, XL Company (NYSE: XL ) and Stericyle (NASDAQ: SRCL ) are the only two companies in the top 10. One can then argue that an equally weighted portfolio would be better, since the rebalancing would only involve stocks which dropped out of the 100 least volatile stocks group. Figure 2: We update the portfolio weights using data through August 06 and the methodology described by the index provider. Only two of stocks, XL and Stericycle from the current top-10 in the SPLV ETF are on the list. (Data courtesy ETFmeter.com) The Best Trending of the 100 Lowest Volatility Stocks We can now ask the question: which are the best trending of the 100 stocks with the lowest volatility in the S&P 500 index? How are they doing? If money is rotating into low-volatility stocks in the face of market worries, then the 10 best trending stocks out of the 100 stocks with the lowest volatility in the S&P 500 index should be largely defensive stocks with steady earnings. We check this hypothesis in Figure 2 below using data through August, 06 2015. We find that out of the lowest 100 stocks, seventeen stocks seem to be surging, and we show them in Figure 3. The charts are somewhat similar, and we show the charts of Kellogg (NYSE: K ) and Clorox (NYSE: CLX ) to illustrate this idea (see Figures 4 and 5). Figure 3: The 17 stocks with the strongest trends in the 100 stocks with the lowest volatility in the S&P 500 index are a who’s who of defensive stocks.

(Chart courtesy StockCharts.com) (click to enlarge) Figure 5: The chart for Clorox looks quite similar to the one in Figure 4, showing the defensive rotation into low volatility stocks. (Chart courtesy StockCharts.com) Summary The low volatility group in the S&P 500 index can offer a respite in the rough seas of a choppy market. There are many alternatives to constructing portfolios with the lowest 100 volatility stocks and combining them with high beta and pure momentum strategies.
