Interview with author Thomas P. Au
I am pleased to announce that Thomas P. Au, cosponsor of this month's Value Investing News members contest and author of A Modern Approach to Graham & Dodd Investing, has agreed to particpate in an interview with me here at the Value Investing News Forum.
Please refrain from posting on this thread until the end of my interview with Tom. You can then either post questions in this forum thread or submit them using the site contact form.
Tom, welcome to our forum, and thank you for taking time out of your schedule to answer some of our questions.


Q: When did you discover that you were a value investor?
When did you discover that you were a value investor?
A: Discovering value investing
I discovered that I had value investor tendencies in the late 1980s, about 5 years after I joined Value Line. I put them aside until the late 1990s, judging that the decade was not a good one for value investors, then revived them in advance of Y2K and the 2000s decade.
Q: What are you doing now?
Are you still a portfolio manager for a large insurance and healthcare provider?
A: I'm with R.W. Wentworth & Co. now
I left Cigna shortly after the publication of the book, in connection with a corporate reorganization. For the past four years, I have been with R.W. Wentworth & Co. a small advisory firm in NYC. Wentworth may be 'morphing" into something bigger as the China arm of a BRIC (Brazil, Russia, India, China) private equity fund, a process that I helped to initiate.
Q: What motivated you?
What motivated you to write A Modern Approach to Graham & Dodd Investing?
A: Motivation for A Modern Approach to Graham & Dodd Investing
The 1990s Internet craze reminded me of the 1920s radio craze, with the potential to create another 1930s type crash (the harder they come, the harder they fall). The book is a warning of such a crash. It is unfolding in a different (slower) way than I had anticipated, but is already a recognizable facsimile of the 1930s-type Great Unwinding.
A: What were some of your challenges?
What were some of the biggest challenges you faced in writing your book?
A: Challenges in writing the book
The biggest challenge was keeping such a long book together on-theme. Probably Graham and Dodd had a similar challenge but then they had the backdrop of the Depression to work from. Reading about the generational theory pulled the whole thing together because of its suggestion of a possible repeat.
Q: What did you learn?
What was the most important thing you learned as a result of writing your book?
A: What I learned
The Graham and Dodd methodology was too rigid for much of the 2000s, even with my modifications. Yet these made the methodology considerably more workable. More modifications are on the way in a new book, to loosen up the requirements further. There is a limit to how far one can go, and I've decided that the "limit" is Warren Buffett.
No two value investors go about things quite the same way, although if you take Graham and Dodd at one end of the spectrum, and Warren Buffett at the other end, you'd pretty much cover the value field. One exception to this rule is Bill Miller of Legg Mason --but I consider him an outlier.
Q: How does your modified investment value approach perform?
I thought your modified investment value approach was interesting. Have you back tested your modified investment value equation, (book value)*(ROE)^2 + 10*Dividends when ROE is > 15? Does it outperform just plain old book value or Graham’s net-net evaluation? What margin of safety do you require with this valuation?
A: Modified investment value
Modified investment value is a more flexible version of the old Graham and Dodd formula. Its main virtue is that it works in non-value markets where there are few Graham and Dodd "net-nets." Put another way, it represents "union" of G&D"s book value, earnings yield, and dividend yield criteria, insofar as a stock can qualify on any one, rather than all three.
Q: What process do you use to search for value opportunities?
What process do you use to search for value opportunities?
A: Value search process
The search process includes reviewing databases such as Value Line and Bloomberg, especially their book value screens. I also look at stocks that have dropped a lot recently. They're either going to recovery, if the company has a good balance sheet, or (probably) go out of business, if the company doesn't. One example was Schering-Plough; bought it just above 14, on the last dip, sold it around 19, my estimate of fair value.
Q: How is your portfolio doing?
Do you still maintain your "Real-Time Experiment" portfolio that you discussed in the book? How has it done lately and what does it currently hold?
A: Real time portfolio
The real time portfolio is still being maintained. It was down about 3.5% at the end of the first quarter, putting it just outside the top decile of its peer group (small cap value). It holds energy stocks, gold, a large position in the Prudent Bear Fund, and Graham and Dodd type issues.
Q: Real estate value investing?
You included an interesting chapter on investing in real estate in your book. Should a Graham and Dodd investor be looking at real estate now? If so, how should they be evaluating real estate investments?
A: Avoid real estate today
I would avoid most real estate today, if for no other reason than the fact that the credit markets are in disarray. On the other hand, if something is selling at 40%-50% of market value, "all cash," it might make sense to buy if you had the cash.
Q: Fixed-income investments?
Buffett recently recommended during the Q&A session of the Berkshire Hathaway Annual Meeting specialized bonds and small cap stocks for portfolios with smaller sums of money. What do you think Buffett meant by specialized bonds?
A: Specialized bonds
"Specialized bonds" sound like high-yield "junk" bonds, in which Mr. Buffett has invested from time to time. These and small cap stocks offer the equity returns that will not be found in large caps during the "recessive" 17 years of the 35-year long cycle.
Q: Generational cycles?
Do the market's recent actions conform to your thesis regarding generational cycles in the stock market that you discussed at the end of the book? Any revisions? Is 2020 still a date of concern?
A: WWII Generational line-up
We have a World War II like generational line-up, with aging Baby Boomers as the new "Rendezvous" (FDR's post-Civil War born generation), Gen-Xers ready to morph into the "New Lost," Eisenhowers and Pattons, and a tech-savvy "Net Gen" who are ready to fight the "next war." Most important, we are on a collision course with developing countries like China that should come to a head around 2020, or shortly before.
Q: Favorite stocks?
Can you share with us some of your current favorite value opportunities?
A: Stock holdings
The key holdings are oil and other sourcers of energy, plus materials, and industrial companies that support these, such as oilfield services companies. I also have small "observer" positions in Taser and other weapons manufacturers, although I consider this theme premature so far ahead of 2020.
Q: Most important fundamentals?
What are the most important fundamentals/ratios value investors should be examining?
A: Margin of Safety & leverage
I measure margin of safety by "leverage" (lack thereof, actually). The smaller the financial leverage, the larger the margin of safety. I don't like to see most industrial companies have a debt to total capital ratio of more than about 30% (the point at which bankruptcy starts to become a real possibility). REITS, utilities, and certain other stable businesses can afford 50-50, but not much more. The other form of leverage is price to book value (asset value, dividend stream, or other measure of value). The lower the ratio, the greater the margin of safety.
Q: Future book plans?
Do you have any plans to write another book in the future?
A: Future book
I am working on another book. The first was a prospective; the second will be a retrospective. And the two will "book-end" what is likely to be a major crisis.
I look forward to reading
I look forward to reading your next book. I really enjoyed Graham & Dodd Investing. Good luck with your current writing and investments.
That concludes the interview - Open for questions
Thank you for your responses to my questions, Tom. Now we will open it up for questions from other members of Value Investing News community.
Question from alexg:
Question from alexg: What seperates your book from the other value investing books?
Question from alexg:
Graham and Dodd's "Security Analysis" was written for the 1930s, an unusually depressed environment. The hypothesis of "A Modern Approach to Graham and Dodd Investing" is that we should now invest in a similar manner, because the U.S. and global economies are headed to the "modern 1930s."
Many post World War II value investors adopted the value "bent," but loosened Graham and Dodd's very strict rules to suit more accomodating times than the 1930s. To take one example, Warren Buffett is a better fair-weather investor and better investor overall than Graham and Dodd. So are the authors of many other value investing books. But I would take the "old masters" in a "stormy weather" environment like the one I foresee coming up.
My first book is a "throwback" toward 1934's "Security Analysis" and away from Ben Graham's own (later) "Intelligent Investor." In this regard, it is "more royalist than the king, more Catholic than the Pope." Perhaps the next book will be closer to the "Intelligent Investor."
Questions from StockJockey
Question sent in by StockJockey:
How did you reconcile your value philosophy at Value Line,which is essentially an earnings momentum approach?
Also, where do you rank Sam Eisenstadt in the history of Wall Street, is he father of quants?
Reply to StockJockey
That's a good question, and it relates to the evolution of Value Line as much as anything else.
Value Line was founded in 1931 as a Graham and Dodd type house reflecting its times. It remained a value shop through the 1950s, with an ideology of "buy stocks below the 'Value Line,' sell stocks above it." But then it moved into the earnings momentum camp in the 1960s along with the then prevailing ethos.
While there, I studied the old archives from the 1930s because I thought the knowledge might come in handy some day. When the 1990s Internet bubble turned out to be a modern facsimile of the 1920s radio craze, I decided that we were headed to the modern 1930s, in which case the Graham and Dodd and Value Line methodologies would be most useful in something approaching their original (1930s) form, not the "evolved" post-1960s version of either G&D or VL.
Style Box Shifts
Tom,
I had one other question. Do you ever try to anticipate shifts between growth and value, and if so, is there any ratio or metric that alerts you too a shift? Valuation?
And does time have anything to do with it, value had a good run this decade, is there enough data to say the cycles run 4-5 years, etc?
Thx

Style Box Shifts
I always want to be on the "value" side of the equation, although what constitutes value varies from time to time.
To determine this, I study "universes," such as Value Line, and look for stocks with below market P/Es, below market P/Bs, and above-average dividend yields, sometimes all three. In general, however, I don't like to pay more than about 20 time normalized earnings for a stock, Ben-Graham style. (This does not refer to situations where the P/E is high because earnings are miniscule, but where the P/B is low.)
One test that I use relates to whether a stock represents "value" relative to its own trading history. For instance, I once recommended Intel at 18 times forward earnings (then a market multiple), on the theory that one was unlikely to see it at such a low valuation for a long time to come. Microsoft, now a mature company, is beginning to look interesting at a mid-teens (below market) multiple. But I considered and rejected buying it just over 20 times earnings in 1989, not feeling comfortable making an assessment that it would go to 40 times earnings sooner than 14.
My internal debate has to do with absolute versus relative value. On average, the median growth stock has a P/E ratio about twice that of the average value stock (and earnings growth potential that's also about two times higher). When this ratio is greater than two, as it was earlier in the decade, buying (absolute) value was an easy call; I'm not going to pay 3 times the P/E for only twice the growth).
Now, the difference in P/E ratios is about 2 to 1, say 25 versus 13. At a time like this, relative value becomes important. Intel was "cheap" relative to its own history, but I'd never pay 18 times earnings for a utility stock. I'm now avoiding certain cyclicals that are trading 15-20 times normalized earnings; a price too "rich" for them.
At market bottoms, the ratio of growth to value P/Es is about 1.5 to 1, e.g., 12 to 8. At this point, the "value" trade is in the "expensive" growth stock. Around 1980, you could get drug companies or Phillip Morris for 12 times earnings, so why pay 8 times for a cyclical with only half as much growth? But those reversals are rare, and come around once or twice in the average career.
