Value And Momentum Are Highly Correlated

One of the most popular research papers on momentum is ” Value and Momentum Everywhere ” by Asness, Moskowitz, and Pedersen. In June 2013, this was published in the prestigious Journal of Finance . I have an earlier blog post which discussed that paper. However, one important item slipped by me then. It was a statement by the authors that value and momentum strategies are negatively correlated. They cited a negative monthly correlation coefficient between value and momentum of -0.24. Asness and his crew have brought up this negative correlation in subsequent writings regarding the merits of momentum and value investing.[1] Other writers and speakers have also been expounding this idea of negative correlation between value and momentum strategies. Long/Short Versus Long Only However, some of us, including myself, did not carefully consider the fact that the Asness et al. study dealt only with long/short momentum and value. This is where you are long high book-to-value and high momentum stocks, while simultaneously short low book-to-value and low momentum stocks. As we will see, the correlations between long/short value and momentum are substantially different than the correlations between long-only value and momentum. The vast majority of the investing world uses long-only rather than long/short portfolios. This applies to both value and momentum strategies. In looking at dozens of mutual and exchange traded funds, I am not aware of any value/growth oriented funds (other than those from AQR using muti-assets or multi-factors) that use a balanced long/short approach. With momentum, I know of only a single public fund [the QuantShares U.S. Market Neutral Momentum ETF (NYSEARCA: MOM ) ] that uses a long/short approach, and it is tiny with only $1.23 million in assets. Therefore, correlations between value and momentum using long/short portfolios are largely irrelevant and may be misleading to most investors. We will show the correlations between U.S. value and momentum stocks using long-only portfolios from the Kenneth French Data Library . We will use the value weighted top one- third of book-to-market value stocks and the top one-third of momentum stocks measured over their prior 2-12 month’s performance during the past 87 years. We will use stocks above the median NYSE in market capitalization. These are the ones that are most commonly traded. By using only large and mid-cap stocks, we avoid the problems associated with micro-cap liquidity. Besides looking at separate value and momentum portfolios, we will also examine a portfolio allocated 50/50 to value and momentum with monthly rebalancing. Our benchmark will be all stocks above the median NYSE market capitalization. No transaction costs or other expenses are deducted. Correlations Here are the monthly correlations from February 1927 to June 2015: MOM VALUE 50/50 MKT MOM 1.00 0.81 0.94 0.90 VALUE 1.00 0.96 0.92 50/50 1.00 0.96 MKT 1.00 The correlations of value and momentum to the market index are 0.92 and 0.90, respectively. As expected, these correlations are very high. What may not be expected is that the correlation between long-only value and long-only momentum is also very high at 0.81. This is dramatically different from the Asness et al. -0.24 monthly correlation between idiosyncratic long/short momentum and value. This difference has important implications for what long-only investors might expect if they invest in both value and momentum. Performance Statistics The return of any blended portfolio is a weighted average of the component returns regardless of the correlations. However, the risk exposure of a blended portfolio can differ greatly based on the correlations between the components. If those components have low or negative correlation, then there should be a substantial reduction in portfolio volatility. However, if the component correlations are strongly positive, as they are here with long-only value and momentum, then there may be little reduction in risk by combining them. We see this is the case looking at results from February 1927 to June 2015: MOM VALUE 50/50 MKT ANN RTN 15.70 15.23 15.46 11.73 STD DEV 19.21 24.75 20.95 20.44 SHARPE 0.59 0.44 0.53 0.38 MAX DD -77.4 -89.0 -83.9 -88.0 Results are hypothetical, are NOT an indicator of future results, and do NOT represent returns that any investor actually attained. Please see our Disclaimer page for more information. The momentum portfolio has the highest return and the highest Sharpe ratio. However, a momentum portfolio of individual stocks also has very high turnover and associated high transaction costs that are not accounted for in the data. See Novy-Marx and Velikov (2014) for an up-to-date analysis of these costs and a review of earlier cost studies. High transaction costs is one reason why I prefer to use momentum with indices and sectors. These work very well with momentum while having substantially lower transaction costs. Value shows almost the same return as momentum and also a higher Sharpe ratio than the large/mid-cap market benchmark.We should understand that if value and momentum had a low or negative correlation, then the standard deviation of a 50/50 mix of value with momentum would likely show a lower volatility than either value or momentum individually. That is not the case here. The standard deviation of the blended portfolio is higher than the standard deviation of the momentum portfolio. It is, in fact, almost identical to the volatility of the market portfolio. Drawdown The same is true with respect to maximum drawdown. The market and value portfolios show around the same maximum drawdown of -88 to -89%. This is based on month-end values. Intra-month drawdowns would be higher. I cannot imagine any investor who would be comfortable losing more than 90% of the value of their portfolio. The maximum drawdown of the momentum portfolio is a little better at -77.4%, but the maximum drawdown of the value/momentum blended portfolio is back up to -83.9%. So should there be value and momentum everywhere? We didn’t think so before, and we don’t think so now, at least not for long-only investors. Momentum without value shows the highest return, highest Sharpe ratio, lowest volatility, and lowest maximum drawdown. But its -77.4% maximum drawdown is still uncomfortably high, and high transaction costs may substantially reduce momentum returns from individual stocks. Summary The way to reduce large downside exposure as well as boost expected returns in the long-run is by using dual momentum as explained in my book and throughout this blog. The absolute momentum component of dual momentum boosts the Sharpe ratios of all the above portfolios and cuts their maximum drawdowns almost in half. Perhaps what we can say is, “Dual Momentum Everywhere!” [1] See reports by the AQR posse, ” Fact, Fiction, and Momentum Investing ” and ” Investing with Style “.

Analysis Of PURA’s Draft Decision In The Proposed UIL/Iberdrola USA Merger

Summary Connecticut regulators issued a draft decision denying UIL and Iberdrola USA’s merger request. While unfavorable, the decision provides a roadmap for the Applicants to obtain approval with a new application. Substantial value will be created through the merger, so investors should expect the merger process to continue. Last week Connecticut’s Public Utility Regulatory Authority (PURA) issued a draft decision denying Iberdrola ( OTCPK:IBDSF ) and subsidiary Iberdrola USA’s (IUSA) proposed acquisition of UIL Holdings (NYSE: UIL ). After the draft decision UIL requested a two month extension to address PURA’s concerns. The extension was also denied, but PURA said that UIL could file a new merger application. On July 7, UIL withdrew their first merger application, and notified PURA that they will soon file a new one. While the denial was a setback, it is not an insurmountable one. The Applicants had expected the merger to be complete by year end. Considering the speed by which PURA reached this draft decision, it seems that the process could be restarted and finished in time to meet that goal. The merger agreement has a walk away date of December 31, 2015, but three-month extensions are available if all closing conditions have been met other than regulatory approvals. So this draft decision has not created a timing problem that will kill the deal. The draft decision is very critical of the Applicants, but PURA has essentially given UIL and Iberdrola a roadmap to obtaining merger approval. The value this deal creates for shareholders and customers should give the companies enough incentive to keep this deal moving forward. IUSA’s tax assets are a big value creator for this merger. Note 20 of IUSA’s 2014 financial statements shows over $1.5B in NOLs and tax credits. These credits were primarily generated by IUSA’s large investments in wind generation. Acquiring UIL gives them more income to be shielded from taxes, leading to faster monetization of these credits. The credits help explain why Iberdrola is willing to pay $10.50/share in cash to UIL shareholders to do the deal. With this huge incentive it is no surprise that the Applicants plan to come back with a new proposal. Down the road, shareholders of the combined company may also be able to benefit from turning some of IUSA’s renewable assets into a yieldco. Yieldcos such as NRG Yield (NYSE: NYLD ) and NextEra Energy Partners (NYSE: NEP ), have been hot lately, as investors hunt for opportunities with better yields. So the cash payment as well as new value streams really give current UIL investors reasons to be in favor of the deal. PURA’s issues with the Applicants are summarized in this excerpt from the draft decision: No compelling evidence was presented by the Applicants that proves this change of control transaction is the best solution for UIL’s plan to grow or become financially stronger, improve performance in a way that provides additional measurable and enforceable benefits to ratepayers, the public service companies themselves or the State. You can bet that UIL and Iberdrola will strongly address these issues in their next application. One big criticism from PURA was there was no synergy savings estimate from the Applicants. These are always tricky to develop because some savings will be from needing fewer employees, but PURA probably wouldn’t look too fondly on a big decline in jobs. Still, there should be savings that comes about from other means besides fewer workers. The NU/NSTAR merger of 2012 gives an example of a synergy savings analysis that was well received by PURA. Here is a summary of the 2012 NU/NSTAR merger estimated benefits: (click to enlarge) (Source: Exhibit 13 of NU/NSTAR merger application ) UIL should expect savings in many of these areas and should be able to come up with something similar. For example, common advertising campaigns can be developed for all of the combined utilities, eliminating duplication. Obviously this will take some work, but with merger experience at both UIL and IUSA over the last few years, a similar analysis should be possible. In the draft decision PURA lists some conditions that were included in the settlements of recent merger cases, and seemed to imply that similar commitments could get this merger over the finish line. These items were: Residential rate freeze of 36 months after the transaction closing Commitment to accelerate the pole inspection cycle Rate credit allocated to retail customer classes Commitment to improve non-storm and storm related service quality performance at a minimum of the 10-year historical average Commitment to open space land Seven year commitment to not move headquarters out of Connecticut Net benefit analysis of synergy savings So if similar commitments and information could be provided it should go a long way toward getting PURA’s acceptance. The Applicants had already proposed no rate cases for 12 months. Since the merger would likely create some type of operational savings, it should give the Applicants the ability to stay out longer than their original proposal. Subsidiary Connecticut Natural Gas (CNG) completed their last rate case in 2014, and subsidiary United Illuminating (UI) finished theirs in 2013. Southern Connecticut Gas’ (Southern) last case was in 2009, and they actually received a rate decrease at the time, so it might be a bit more difficult to extend at that subsidiary, but it seems like the other utilities should be able to last longer than one year. UIL also offered to give a $5M rate credit to some residential customers. It appears that PURA wants these credits spread over a wider range of residential customers. In the NU/NSTAR case, CL&P gave $25M of credits to all residential customers. Since CL&P is bigger than the UIL companies, the Applicants could likely get by with something smaller. One item that was a big sticking point in PURA’s argument against the merger but not in the above list was ring fencing. There was actually no ring fencing in the NU/NSTAR merger from a few years ago, and PURA’s request for these conditions is basically unprecedented in Connecticut. The Applicants did agree to some ring fencing type items in their merger request, but now that they know how important this is to PURA they will likely add a few more. PURA also implied that one primary issue led to their draft denial of the application. In their analysis they said: The Authority need only look to its Decision dated November 10, 2010 in Docket No 10-07-09, …[ UIL purchase of Southern and CNG (2010 Decision) ]… for the exact reasons why the Proposed Transaction should be denied. (emphasis mine) PURA then references P.5 of the 2010 Decision, which said immediate benefits at the time would include: Local control, long-standing record of commitment to the state and region, experience with Connecticut regulation and legislation, expertise in conservation and load management, and the change to Connecticut as the base for services currently provided to CNG and Southern from outside Connecticut. PURA also references items from the 2010 Decision estimating savings in overhead costs of over $11M. PURA then writes: The proposed transaction looks to remove these stated benefits just five years later. Therefore, to approve the Proposed Transaction would be a direct contradiction to what the Authority previously determined was in the public interest. PURA then mentions concerns about the Applicant’s commitment to their venture over the long term. They cite Iberdrola’s sale of CNG and Southern just two years after acquisition as evidence that their dedication to Connecticut could be shaky. While PURA makes some points, they should be addressable by UIL and IUSA. By taking best practices from both companies, those shared services costs that were so high five years ago during the gas acquisition should be decreasing. And if not, it seems like the merging parties could commit to limiting the allocated costs that are collected through rates for a number of years. Secondly, regarding the commitment issues, take a look at the following information from the utility operating companies of the Applicants: The three gas companies are dramatically smaller than the other three utilities Iberdrola obtained (NYSEG, RGE, and CMP) when they bought Energy East in 2008. Back in 2010 these gas companies would likely have been lost in a company focused on New York and Maine, so they were sold to UIL where they could receive acceptable attention and not fall through the cracks. Bringing all of the new UIL into the IUSA fold adds a company that is on par with IUSA’s Maine and New York operations. IUSA’s self-interest in desiring success at this now important part of the company should take care of these commitment concerns. PURA shouldn’t hold it against Iberdrola that these were trimmed back in 2010, because it really didn’t make sense for IUSA to own them at the time. PURA also seemed overly critical in a few areas, likely because the application was lacking in the areas mentioned above. For one thing, PURA criticized the Applicants for not providing any specific best practices that could be implemented. Obviously determining which companies have the best practices in different operations takes time and sharing intimate details of how companies operate probably should not be done until the merger is complete. The NU/NSTAR merger approval does not list specific best practices and says: This merger will provide the inherent benefits of bringing together two corporations … which will create opportunities to identify and implement best practices. So there is precedent that a merger can be approved before the identification of specific best practices to implement has been completed. The Applicants also committed to develop plans to optimize resources to respond to storms and emergencies. PURA said they give the applicants no credit for this because PURA “… assumes that these types of responses are a normal course of business and not an incentive to approve the transaction .” While it is true that utilities all around the country work together to help during storms, the integration of response teams can be much more thorough if they are part of the same company. So PURA really should be giving the Applicants some credit here. Conclusion: It appears that this merger will create substantial benefits for both shareholders and customers. PURA seems to want a more quantifiable commitment from the Applicants about the benefits customers will receive, and PURA has essentially given the Applicants a roadmap to do this. Investors should not consider the recent denial of the merger an overwhelming challenge to getting the deal done.

How To Find The Best Style Mutual Funds: Q2’15 In Review

Summary Finding the best mutual funds is an increasingly difficult task in a world with so many to choose from. Performance of a mutual fund’s holdings equals the performance of the fund. Our coverage of mutual funds leverages the diligence we do on each stock by rating mutual funds based on the aggregated ratings of their holdings. Finding the best mutual funds is an increasingly difficult task in a world with so many to choose from. How can you pick with so many choices available? Don’t Trust Mutual Fund Labels There are at least 904 different Large Cap Value mutual funds and at least 6391 mutual funds across twelve styles. Do investors need 500+ choices on average per style category? How different can the mutual funds be? Those 904 Large Cap Value mutual funds are very different. With anywhere from 17 to 1003 holdings, many of these Large Cap Value mutual funds have drastically different portfolios, creating drastically different investment implications. The same is true for the mutual funds in any other style, as each offers a very different mix of good and bad stocks. Large Cap Value ranks first for stock selection. Small Cap Blend ranks last. Details on the Best & Worst mutual funds in each style are here . A Recipe for Paralysis By Analysis We firmly believe mutual funds for a given style should not all be that different. We think the large number of Large Cap Value (or any other) style mutual funds hurts investors more than it helps because too many options can be paralyzing. It is simply not possible for the majority of investors to properly assess the quality of so many mutual funds. Analyzing mutual funds, done with the proper diligence, is far more difficult than analyzing stocks because it means analyzing all the stocks within each mutual fund. As stated above, that can be as many as 1003 stocks, and sometimes even more, for one mutual fund. Any investor worth his salt recognizes that analyzing the holdings of a mutual fund is critical to finding the best mutual fund. Figure 1 shows our top rated mutual fund for each style. Figure 1: The Best Mutual Fund in Each Style Sources: New Constructs, LLC and company filings How To Avoid “The Danger Within” Why do you need to know the holdings of mutual funds before you buy? You need to be sure you do not buy a fund that might blow up. Buying a fund without analyzing its holdings is like buying a stock without analyzing its business and finances. No matter how cheap, if it holds bad stocks, the mutual fund’s performance will be bad. PERFORMANCE OF FUND’S HOLDINGS = PERFORMANCE OF FUND If Only Investors Could Find Funds Rated by Their Holdings The Eaton Vance Hexavest U.S. Equity Fund (MUTF: EHUIX ) is the top-rated Large Cap Value mutual fund and the overall best fund of the 6391 style mutual funds that we cover. The worst mutual fund in Figure 1 is the Royce Special Equity Fund (MUTF: RSEIX ), which gets our Neutral rating. One would think mutual fund providers could do better for this style.
