Value Series II: AT&T Employees Can Use the P/CF Ratio to Find Value

Healthcare Provider Update: Healthcare Provider for AT&T: AT&T collaborates with multiple healthcare providers to ensure its employees receive quality health coverage. One primary partner is UnitedHealthcare, which offers health plans tailored for AT&T employees. Potential Healthcare Cost Increases in 2026: As the landscape of healthcare evolves, AT&T employees may face significant challenges with rising healthcare costs in 2026. Experts anticipate a steep surge in premiums for Affordable Care Act (ACA) marketplace plans, with some states projecting increases exceeding 60%. This rise is largely attributed to the potential expiration of enhanced federal premium subsidies and soaring medical expenses. Without action from Congress to extend these subsidies, over 22 million enrollees may see their out-of-pocket costs increase by more than 75%, making it imperative for workers to prepare financially for the coming changes.

Given current market volatility, we think now is a good time to revisit important value metrics with AT&T employees and retirees in our four-part series. In the second part of this four-part value series, we will look at the Price-to-Cash Flow ratio. Investors are often looking for ways to beat the market. If you're one of those investors, you should consider the following proven strategy that has been implemented by some great investors. Value investors figured out how to beat the average annualized returns of the S&P 500 a long time ago, and many have successful track records spanning several decades to prove it. The most famous value investor, of course, is Warren Buffett, but there are many others, including Benjamin Graham, David Dodd, Charlie Munger, Christopher Browne, and Seth Klarman.

This investment style focuses on four metrics that characterize a value investment. These four metrics include the Price-to-Earnings Ratio, the Price-to-Cash Flow Ratio, High Dividend Yield, and the Price-to-Book Ratio. These metrics, as you will see, are strong indicators of undervalued security. These undervalued AT&T securities consistently outperform the market. We will examine the effect of investing based on certain characteristics and how their investment returns are correlated. Today, we will look at the Price-to-Cash Flow ratio (P/CF), which we think can be a valuable tool in planning for AT&T employees' retirements. 

Many believe that using cash flow, rather than accounting earnings, delivers a more accurate picture of a company’s business performance, which in turn may lead to better investment decisions and investment performance. We understand the importance of researched solutions for AT&T employees. Set out below are the results of two Fama and French[1] backtests of the cash flow yield (the inverse of the P/CF ratio) data from 1951 to 2013. As of December 2013, there were 2,526 firms in the sample (Carlisle-PCF, P2). The value decile contained the 269 stocks with the highest cash flow yield, and the glamour decile contained the 311 stocks with the lowest cash flow yield. The average size of the glamour stocks is $4.74 billion and the value of stocks is $4.80 billion. (Note that the average is heavily skewed by the biggest companies.

For context, the smallest company included has a market capitalization today of $272 million, which is much smaller than the average, but still investable for most investors). Stocks with negative cash flow were excluded. Portfolios are formed on June 30 and rebalanced annually. In this backtest, the two portfolios are weighted by market capitalization, which means that bigger firms contribute more to the performance of the portfolio, and smaller firms contribute less. Here we can see that the value decile has comprehensively outperformed the glamour decile, returning 16.7 percent compound (18.6 percent in the average year) over the full period versus 9.3 percent for the glamour decile (11.5 percent in the average year) (Carlisle-PCF, P3).

The reason for the value’s outperformance is simply due to the fact that the value portfolios generated more cash flow per dollar invested; 27.2 percent versus 4.3 percent for the glamour portfolio (Carlisle-PCF, P5). (I used a rolling average.) The “average” I’ve quoted is for the full period. The rolling average has been higher, but it’s rarely been lower. The rolling average is the annualized average return over the 5 yrs following each year-long period (sometimes called a 5-year rolling return).

As we discussed previously, values' outperformance over glamour is not a historical anomaly. If we examine just the period since 1999, we find that, though the return is lower than the long-term average, value has continued to be the better bet. Value has continued to outperform glamour since 1999, beating it by 8.7 percent compounded, and 6.2 percent in the average year (Carlisle-PCF, P7).

The reason for lower returns recently may be due to the popularization of simple value strategies. However, I think it’s because the market is still working off the massive overvaluation of the late 1990s Dot Com boom. We think that a value-based strategy is the best course of action for AT&T employees and retirees.

Market capitalization-weighted returns are useful for demonstrating that the outperformance of value over glamour is not due to the value portfolios containing smaller stocks. Unless you’re running an index (or hugging an index), they’re not really meaningful. The easiest portfolio weighting strategy is to simply equally weight each position. (If we’re prepared to put up with a little extra volatility for a little extra return, we can also Kelly weight [2] our best ideas). Kelly Weighting is determined by the Kelly Criterion which is a formula used to determine what percentage of capital should be used in each trade to maximize long-term growth. There are two key components to the formula (Kelly % = W- [(1 - W) / R]): the winning probability factor (W) and the win/loss ratio (R). The winning probability is the probability trade will have a positive return.

The win/loss ratio is equal to the total positive trade amounts divided by the total negative trading amounts. The result of the formula will tell investors, what percentage of their total capital they should apply to each investment. The equal weight return statistics for the cash flow yield are displayed below. In the equal weight backtests, the value generated 20.7 percent compounded (23.8 percent on average), beating out glamour’s 9.3 percent compounded return (12.5 percent on average) (Carlisle-PCF, P9). You might note the small advantage for the cash flow yield’s value decile over the earnings yield’s value decile, 20.7 percent versus 20.1 percent. We’ll examine the significance of this small win by cash flow in the coming weeks.

Again, the value portfolios generate more cash flow than the glamour portfolios, generating 24.6 percent on average versus 4.1 percent in the glamour portfolios (Carlisle-PCF, P10).

As we saw last week, the average cash flow yield for the equally weighted value portfolio is slightly lower than the average cash flow yield for the market capitalization-weighted portfolios. This indicates that, over the full period, bigger stocks tended to be a cheaper method for buying cash flow than smaller stocks. That won’t always be the case, but it’s interesting, nonetheless. In the equal-weight portfolios, value has significantly outperformed glamour since 1999, beating it by 11.1 percent compounded, and 10.0 percent in the average year (Carlisle-PCF, P11). Since we value research just as much as AT&T employees and retirees, mentioned below is another study analyzing the P/CF metric. 

In a Brandes Research Institute study, exhibit 6 on the following page illustrates the global all-cap findings across three price metrics. The results confirmed a consistent value premium across all metrics. We will focus on the P/CF ratio and the outperformance in the decile 10 value stocks. The smallest outperformance between decile 1 glamour stocks and decile 10 value stocks can be observed with the P/B measurement, where the average outperformance was 7.1% (Brandes, p. 8)

In the same Brandes study, they looked at how the Price-to-Cash Flow held up in the U.S., Non-U.S., and Emerging Markets. Looking at rolling 5-year annualized returns of Price-to-Cash Flow deciles from 1980-2014, it can be seen that the lower price-to-cash flow deciles significantly outperform those in the higher Price-to-Cash Flow deciles. The results can be seen on the graph “Appendix C: Findings by Regions Using P/CF Deciles”. While all of the lowest Price-to-Cash Flow deciles outperform the high Price-to-Cash Flow deciles, the biggest premiums happen outside of the United States. In fact, the largest premium can be seen in emerging markets where companies that generate more cash are better suited to withstand market downturns. We want to emphasize just how valuable P/CF ratio analysis can be as a tool in planning for AT&T employees' and retirees' retirements.

Currently, the average Price-to-Cash Flow (P/CF) for the stocks in the S&P 500 is 13.9. But just like the P/E ratio, a value of less than 15 to 20 is generally considered good. A study conducted by Zach’s shows a strong correlation.

 In their testing, they found that a P/CF between 0-10 produced the best results (17.1% over the last 10 years (using a 1-week rebalancing period). The second-best results came in the range of 10-20 with a 10.2% gain (Zacks, L12). However, once you get over 30, the odds point to a loss (-2.8%). And over 40, the odds of loss are even greater at -6.9%. We can clearly see that low-price-to-cash-flow stocks significantly outperform high-price-to-cash-flow stocks.
