"Every Detail Shows Rob's Respect
for His Information and His Reader."
"You’ve Accomplished Something Radical
With Your Idea of Passion Saving."
"Big Moves Out of Stocks Should Not Be Done at All. But Strategic Asset Allocation Can Be Done At Very Rare Times, Maybe Six Times in an Investor’s Lifetime, Three Times When the Market Is Stupidly High and Three Times When Stupidly Low."
"Valuation-Informed Investing and Passive Investing
Share More of a Common Ancestry

"Your Ideas Are Sound."
"For Years, the Investment Industry Has
Tried to Scare Clients Into Staying Fully Invested
in the Stock Market at All Times, No Matter
How High Stocks Go. It's Hooey.

"Valuation-Informed Indexing Provides More Wealth for 102 of 110 of the Rolling 30-Year Time-Periods While Buy-and-Hold Did Better in Eight of the Periods."
"There Is a Growing Behavioral Economics Movement, But It So Far Has Had Limited Impact. Economists Are Not Fond of the Softness and Imprecision of Psychology. These Notions Are Considered Vaguely Unprofessional and Flaky."

"Inflammatory."

"This Report Offers A Fresh Perspective That Is Rarely Found In Other Financial Literature."
"Rob Bennett Says That Market Timing Based on Aggregate P/E Ratios Can Be a Far More Effective Strategy. This Claim Is Consistent With Shiller's Analysis and I Can See How It Might Be So."

What Weston Price’s Ideas Did for Food,
You’ve Got Our Attention."
"I Have Looked at His Website and Reviewed His Research and Find It Both Compelling and Completely Logical and Common-Sense-Based."
"If Investors Paid More Attention to Valuations, We Would Have Fewer Boom-and-Bust Cycles. The Investing Institutions Are Definitely Going to Avoid It Because It Affects Their Income."
"The Calculators on Your Site Are Great Resources. It Amazes Me How So Many People Can Say 'Valuations Matter' Yet, in the Next Breath, They'll Say That We Should Ignore Valuations."
"Must Read As Per My Viewpoint
For All Value Seekers."
"His Approach Is Both Mathematically Rigorous
and Easy to Understand."
"Difficult Subjects Can Be Explained to the Most Slow-Witted Man If He Has Not Formed Any Idea of Them. But the Simplest Thing Cannot Be Made Clear to the Most Intelligent Man If He Believes He Knows Already What Is Laid Before Him."
"I Am Not Afraid. I Was Born to Do This."
"I Certainly Have Seen the Academic Profession Squelching Unfashionable ideas and Have Often Been on the Wrong Side of It. Kuhn Shows How Most Pathbreaking Scientific Ideas Are Rejected at First, Usually for Decades.”
"First They Ignore You, Then They Ridicule You, Then They Fight You, Then You Win."
"We Cannot Assume the Existence of Predictability Just Because There Are No Studies That Fully Reject It."
"I Am Also Extremely Grateful to Rob Bennett for Motivating This Topic and Contributing His Experience and Encouragement."
"Rob Bennett Was an Early Pioneer in 3rd Generation Modeling by Advocating (Through Various Online Forums) that Withdrawal Rates Must Be Adjusted for Market Valuations Consistent with Research by Campbell and Shiller."
"I Am Fascinated by the Growing Body of Research that Revolves Around the P/E10 Ratio by Robert Shiller, Doug Short, Wade Pfau, Michael Kitces, John Hussman, Crestmont Research, Jim Otar, Mike Philbrick, Adam Butler & Rob Bennett."
"Rob Is an Enigma in the Personal Finance World. He Has Interesting Theories on Investing Based on Market Valuations. But He Weaves a Tale Which Makes the Stories of Alexander Litvinenko & Gareth Williams Seem Tame by Comparison."
"In Recent Years, the 4 Percent Rule
Has Been Thrown Into Doubt."
"A Safe Withdrawal Rate Is Very Dependent
on the Valuation of the Stockmarket
at the Retirement Date."
"I Have Read Everything I Can About Valuation-Informed Indexing. Buy-and-Hold Is Extremely Problematic. I Respect the Passion, Hard Work and Research That You Have Put Into This Very Important Issue. Your Work Has Huge Value."
"The World of Personal Finance Blogging Needs More Rob Bennetts. He’s Passionate. He’s Intelligent. He’s Writing Things That Go Against the Grain."
"Beyond Awesome."
"The Wealth Management Industry Seems Intent on Containing This Discussion for Fear Clients Might Discover that the Emperor Has No Clothes."
"Recommended Reading."
“All Who Are Still Holding Equities at Present Levels Because Their Financial Adviser Insists that Timing Market Cycles Is Impossible to Do -- Read This!"
"The Fact that Aggressive and Short-Term Market Timing Was Unproductive Did Not Mean That There Were Never Times When It Would Be Wealth-Maximizing to Get Out of the Market."
"The Amount of Return You Can Expect From a Diversified Equity Portfolio Is Inversely Correlated to the Market Valuation at the Start of the Holding Period. It Is One of the Most Robust Statistical Relationships in Modern Finance."
"Why Would Your Job Be Jeopardized
By Such a Sensible Claim?"
"Received Worrisome E-Mail from Rob Bennett. Warns of Risk with Buy-and-Hold Investing
-- I Have No Clue."
"As Attorney, Tax Expert and Financial Writer Rob Bennett Told Us, the Problem Is That, By the Time Shiller Published His Research, Many Big Names Had Already Endorsed Buy-and-Hold."
"This Seems to Me to Be a Fundamental Challenge to Some of the Most Basic Tenets of the Boglehead Paradigm."
"You Want to be Very, Very Wary of Anything Connected with Rob Bennett, the Most Infamous Troll in the History of Investing Forums on the Internet."
“I’ve Had My Fill of Those Long-Winded Posts that Include Distortions, Unsubstantiated Claims, Misquotes and Comments Taken Out of Context.”
"Haven't You Noticed Yet That NO ONE Discusses Your Ideas, NO ONE Mentions Your Name, NO ONE Goes To Your Web Site."
"I've Had Similar Experiences. I Know of Two Young Professors Who Wanted to Do Research on Fundamental Index and Reported to Me That Their Colleagues Advised Them That This Line of Research Could Derail Their Career Prospects."
"As with Drug Studies Funded by Drug Companies, It Would Be Churlish to Suppose that the Chicago School of Business Was in the Bag. But It Would Also Be Idealistic to Assume That There Was No Funding Bias at All."
"This Sort of Intimidation Is Not Acceptable. The Cigarette and Pharmaceutical Industries Found Research Supporting Their Products By Funding It. But That Was Big Money Supporting Outcomes, Not Dissuading Others."
"Financial Economists Gave Little Warning to the Public About the Fragility of Their Models. There Is No Ethical Code for Professional Economic Scientists. There Should Be One."
"The Situation [Referring to the Intimidation Tactics Used to Silence Academic Researcher Wade Pfau's Reporting of the Dangers of Buy-and-Hold Investing Strategies] Seems Well Below Any Professional and Academic Acceptable Standards."
Many Academics Can Become Quite Strident When Their Views Are Challenged. Academia Is Often Subject to Self-Serving Bias That Obliterates Ethical Bounds."
"I Don't Like Too Much the Conspiracy Idea. I Am Not Pressured By Anyone in My Research."
"This Is What Investing Should Be -- Calculated, Deliberate, Confident, Informed and Simple."
"It Is Obvious that Rob, in Attempting to Identify New Safe Withdrawal Rate Strategies...Is Goring Your Ox. If Rob Improves on [the] Safe Withdrawal Rate Methodology, the Implication Is Clear: You Are All, Metaphorically, Out of Business."
"I Applaud His Effort to Inject Another Piece of Objectivity Into a Very Complex, Highly Subjective Topic -- Making Money in the Market."
"Naturally, I Am Finding That Valuation-Informed Indexing Can Allow You to Reach a Wealth Target With a Lower Saving Rate and to Use a Higher Withdrawal Rate in Retirement Than You Could With a Fixed Allocation."
"A Careful Examination of Past Returns Can Establish Some Probabilities About the Prospective Parameters of Return, Offering Intelligent Investors a Basis for Rational Expectations About Future Returns."
"The Ability to Estimate the Long-Term Future Returns of the Major Asset Classes Is Perhaps the Most Important Investment Skill That An Indivisual Can Possess."
"The Stock Market Resembles Roulette. In Both Cases, the Accuracy of Sensible Forecasts Rises Over Time."
"Returns Are for the Most Part a Matter of Simple Arithmetic...Much of Our Industry Seems Fearful of Basic Arithmetic of This Sort."
"How Can It Be That One-Year Returns Are So Apparantly Random and Yet Ten-Year Returns Are Mostly Forecastable? In Looking at One-Year Returns, One Sees a Lot of Noise. But Over Longer Time Intervals the Noise Effectively Averages Out and Is Less Important."
"The Notion That Rich Valuations Will Not Be Followed By Sub-Par Long-Term Returns Is a Speculative Idea That Runs Counter to All Historical Evidence. It Is an Iron Law of Finance That Valuations Drive Long-Term Returns."
"It's January and the Temperature Is Below Freezing. If You Asked Me Whether It Will be Warmer or Cooler Next Tuesday, I Would Be Unable to Say. However, If You Asked Me What Temperature to Expect on April 9, I Could Predict "Warmer Than Today" and Almost Surely Be Right."
"If the Response Is "Who Knew?", It Won't Be Much Comfort for Retirees in the Employment Line at Wal-Mart. This is Especially True Since a Rational Understanding of History and the Drivers of Longer-Term Stock Returns Can Help Retirees To Avoid That Surprise."
"New of the Demise of the Random Walk Has Only Very Slowly Spread, In Part Because Its Overthrow Came as a Shock. If the Random Walk Hypothesis Were Correct, the Most Likely Return Would Be the Historic Average Return. The Evidence, However, Is Strongly Against This."
"I Don't Think We Can Debate the Merits of This Type of Forecasting [Referring to the Numbers Generated by The Stock-Return Predictor] Unless We Believe 'This Time It's Different.'"
"I've Seen Absolutely Nothing From You That I Can Use in a Tangible Fashion to Formulate an Investment Plan. Your Ideas Are So Mushy That It's a Complete Waste of Time to Even Consider Them."
"Do You Really Think Your Tool
[The Stock-Return Predictor]
Is 'Wiser' Than the Market?
If It Was That Easy,
Everybody Would Be Doing It."
"The Expected Return of Stocks [As Reported By The Stock-Return Predictor] Needs To Be At Least the Treasury Inflation-Protected Securities (TIPS) Rate for Stock Investing To Make Sense."
"I Have Used Valuations to Adjust My Asset Allocation For Many Years With Very Favorable Results."
"I Don't Care If You Do or Don't Believe That the Market Will Behave Similarly in the Future As It Has in the Past. Either Way, This [The Stock-Return Predictor] Is an Excellent Way to Understand What the Market Has Done In the Past."
"My Role Is To Give People Who Don't Like What the Historical Stock-Return Data Says About the Effect of Valuations on Long-Term Returns Somebody To Yell At On Internet Discussion Boards."
"It Really Is a Shame and Indefensible That So Many Feel the Need to Jump Into It With No Interest of Posting on the Topic But Just to Disrupt. Are You That Insecure? Some on the Forum Have an Interest in This Topic. If You Don't, Stay Out!"
"Irrational Behavior Does Follow Patterns. But How Many Experts in Behavioral Finance Believe That Such Knowledge Can Be Used to Predict Markets? Basically, None. Your Model Cannot Attain the Level of Predictive Value You Claim."
"The Safe Withdrawal Rate Studies Are Based on History. This [The Retirement Risk Evaluator] Shows, Based on the Same History, What the Probabilities Are for the Future at Various Starting Points. If the First Has Value, Then Surely This Does Too."
"There Are Hundreds of People Who Contributed to This. This Calculator [The Stock-Return Predictor] Demonstrates in a Compelling Way the Power of This New Internet Discussion-Board Communications Medium."
"A P/E10 of'26' Is Bad. Now Look at the 30-Year Return Predicted by the Calculator -- 5.4 Percent Real. That's Not Bad. There Are All Sorts of Strategic Implications That Follow From Understanding That Stocks Provide Different Sorts of Returns Over Different Sorts of Time-Periods."
"I Would Never Invest in Anything Without Having Any Idea What the Expected Return Is. For Instance, I Would Not Walk Into a Bank And Say "I'll Take One Certificate of Deposit, Please" WIthout Asking What Rate They Are Offering."
"I've Seen Things Said on Investing Boards That I Have Never Heard Said in Discussions of Any Non-Investing Topic. The Question of Whether Valuations Affect Long-Term Returns Is a Topic That Causes People More Emotional Angst Than Does Abortion or Impeachment Proceedings or the War in Iraq."
"It's Not Possible For Those Who Have Come to Believe That Stocks Are Always Best to Accept that Valuations Matter. The Two Beliefs Are Mutually Exclusive. If Valuations Matter, There Is Obviously Some Valuation Level At Which Stocks Are Not Best. The Two Paradigms Cannot Be Reconciled."
"The Great Safe Withdrawal Rate Is Over. Rob Bennett Has Won.The Technical Evidence Supporting This Assertion Is Rock Solid."
"I Am Afraid that the Emperor SWR [for "Safe Withdrawal Rate"] Has No Clothes."
"I Cite You and John Walter Russell in My Paper as the Earliest and Strongest Advocates of This Approach [New School Safe Withdrawal Rate Research]."
"Dear Rob -- I Just Became Aware of Your Past Research in September. Since Then, I've Read Archives From Many Discussion Boards and Websites, and I Always Find Your Writing to Be Very Interesting and Intriguing."
"I Think Rob Bennett Did Provide An Important Contribution in Terms of Describing a Way for P/E10 to Guide Asset Allocation for Long-Term Conservative Investors. I Also Think He Was Right on the Issue of Safe Withdrawal Rates."
"What Studies Show This [That Long-Term Timing Doesn't Work]? In Particular, Are There Some Academic Studies That I Haven't Found Yet? That's All I Want to Know."
"Because the Precise Timing of This Mean Reversion Is Not Known in Advance, Expecting the Result to Happen in the Short-Term Will Not Be Possible. But Long-Term Investors Who Can Be Patient Can Wait for This Mean Reversion and Will Eventually Come Out Ahead."
"Your Work Is at Odds with the Ethos of the Board -- Here the Theme is John Bogle's Philosophy, Which Eschews Market Timing. This Board Came Into Existence to ESCAPE One Individual, the Very Individual With Whom You Have Openly Aligned Yourself."
"The Problem With Long-Term Market Timing Is That It Takes Too Long to Find Out If You Are Right or Wrong."
"Why Is It Such an Odious Violation of the Tenets of Bogleheadism to Explore Whether Someone Who Has Enough Patience Might Be Able to Benefit from the Transitory Nature of Speculative Returns (the Idea That the P/E Ratio Eventually Ends Up Where It Started)?"
"Let Me Explain Why I Posted About This Here. Valuation-Informed Indexing Has Had Critics for Years. But Until Norbert Did It In 2008, Nobody Seemed to Have Provided a Serious Investigation of It. I Couldn't Understand Why. That Bothered Me."
"If You Really Don't Like Market Timing in Any and All Forms, You May Not See Any Point in an Empirical Investigation. You View Me as One of a Long Line of Hucksters Trying to Sell You Some Snake Oil. I Don't Want to Be Such a Person."
"Having a Completely Ineleastic Demand for Equities Is a Bit Bonkers. No One Acts That Way with Life's Other Important Commodities. Campbell Advocates a Linear Valuations-Based Strategy so That You Wouldn't Be Making Big Changes. This Would Be Like Rebalancing But More Flexible."
"The Whole Idea of Valuation-Informed Indexing Belongs to You. Do You Mind if I call the Paper 'Valuation-Informed Indexing'? I Would Give You Credit. I Have Been Toying With the Idea of Sending the Paper to the Journal of Finance, Which Is the Most Prestigious Journal in Academic Finance."
"I Definitely Need to Cite You as the Founder of Valuation-Informed Indexing, As I Have Not Found Anyone Else Who Can Lay Claim to That. Shiller Pointed Out the Predictive Power of P/E10 But Never Discussed How to Incorporate It Into Asset Allocation, As Far As I Know."
"I Tested a Wide Variety of Assumptions About Asset Allocation, Valuation-Based Decision Rules, Whether the Period Is 10, 20, 30 or 40 Years, and Lump-Sum vs. Dollar-Cost Averaging To Show That the Results Are Quite Robust to Changes In Any of These Assumptions."
"Yes, Virginia, Valuation-Informed Indexing Works!"
"I Wrote Up the Programs to Test Your Valuation-Informed Indexing Strategies Against Buy-and-Hold and I Am Quite Excited. You Say in the RobCast That VII Should Beat Buy-and-Hold About 90 Percent of the Time. I Am Getting Results That Support This."
"Never Underestimate the Power of a Dominant Academic Idea to Choke Off Competing Ideas, and Never Underestimate the Unwillingness of Academics to Change Their Views in the Face of Evidence. They Have Decades of Their Research and Academic Standing to Defend."
"There's So Much That's False and Nutty
in Modern Investing Practice."
"Following Conventional Wisdom Has Led a Generation of Investors Down the Road to Ruin."
"It Is Sad That the Idea That Price Doesn't Matter...Should Ever Have Been Seriously Considered".
"The Conventional Wisdom of Modern Investing Is Largely Myth and Urban Legend."
"Economics Is a Dog's Breakfast of Theoretical Ideas and Alleged Causal Relationships That Are At All Times Unproven and In Dispute."
"Since They Did Not Diagnose the Disease, There Is Little Popular Confidence That They Know the Cure. What If Economics Is, Actually, At the Same Level as Medicine Was When Doctors Still Believed in the Application of Leeches?"
"One of the Most Remarkable Errors
in the History of Economics."
"Everything Has Fallen Apart."
"We Wonder Why Funds and Banks, Full of the Best and Brightest, Have Made Such a Mess of Things. Part of the Reason Is That We Have Taught Economic Nonsense to Two Generations of Students."
"Perhaps Most Scandalously, the Theory [Behind Buy-and-Hold] Remained Received Wisdom Long After Empirical and Theoretical Arguments Had Demolished It Within the Academic Community."
"I Love the Humans Dearly (the Title of the Book I Am Writing Is Investing for Humans: How to Get What Works on Paper to Work in Real Life) But They Can Be a Trial at Times. Hey! Helping the Humans Learn What It Takes to Invest Effectively Is Not All That Different From Being Married!
"We Are Going to See Hearts Melt Following the Next Crash. I Will Be Working Side-By-Side With All of My Many Buy-and-Hold Friends to Rebuild Our Broken Economy."
"Wow, I Did Not Realize You Had Achieved This Much Success and Had Many Devoted Believers/Followers. That’s Great, Then Ignore the Opposition. It Is Great to Have Opposition: That Means You Are Doing Something Right."
"I Do NOT Believe I Know It All. I Believe That Shiller Discovered Something Very Important and It Appalls Me That More People Are Not Exploring the Implications of His Findings. My Aim Is To Launch a National Debate."
"I Can See How Many Readers Would Be Put Off by the Somewhat Sensational/Scandalist Tone and Would Not Persevere to Read, Thinking You Are Losing Your Mind."
"I LOVE Everything About Buy-and-Hold Other Than the Failure to Encourage Investors to Take Price Into Consideration When Setting Their Stock Allocations. That's a Mistake That Was Made Because Shiller’s Research Was Not Available at the Time The Strategy Was Being Developed."
"Valuation-Informed Indexing Sounds Like a Real Thing. If It Is and I Can Thoroughly Understand It, Then It Will End Up In My Classrooms and in My Students' Minds (Of Course, With References to You and Wade)."
"I Can Confirm Wade Pfau's Experience. Whenever I Send My Papers to the Financial Analysts Journal or Similar Traditional Journals, I Get Rejected."
"As a Fan of Thomas Kuhn's The Structure of Scientific Revolutions, I Know That Progress Can Be Frustratingly Slow and What Is Typically Needed Is Either a Crisis or the Ascent of a New Generation of Scientists Who Did Not Build Their Careers on the Old Models and Theories."
"We Trace the Deeper Roots [of the Financial Crisis] to the Economics' Profession's Insistence on Constructing Models That, By Design, Disregard the Key Elements Driving Outcomes in Real World Markets."
"Rob Gets Himself So Worked Up Over What Someone Else Is Doing With Their Own Money and Not Bothering Rob in the Least. As Long As They Aren't Knocking on Your Basement Door, What Do You Care? They Are Happy and Content. Leave Well Enough Alone and Focus on Your Own Account."
"I've Been on Forum Since the BBS Days and I Think Rob is Special. He Could Be an Internet Meme If He Put Some Effort Into It. Someday, He Will Realize That the Only Thing He's Good At Is Being an Epic Loser. He Just Needs to Embrace That Idea and Run With It. Watch Out, LOLCats, Here Comes Pathetic Guy!"
"Your Lies Are Not Even in the Realm of the Possible, Much Less Actually Credible, Much Less Actually True."
"I'm Your Friend. I Am Not a Boil on Your Ass."
"You Guys [the Greaney Goons] Are the Same Jokers Who Have Done This Before, Sparring with Rob Over Nonsensical Issues On This Site and Others, Leveling Personal Attacks, and You Don't Even Use Real Names! Rob Is Entitled to His Opinion, But the Fact That You Challenge Every Jot and Tittle of What He Says Makes It Clear You Have An Unholy Agenda. Please Take It Elsehwere."
"Rob, Take This As Friendly Advice. You're a Smart and Articulate Guy and You Could Be Making Valuable Contributions to This Discussion. I've Dealt with the Mentally Ill Before and I've Found That They Sometimes Can Be Reasonable If Gently Redirected."
"Always Remember Others May Hate You, But Those Who Hate You Don't Win Unless You Hate Them, and Then You Destroy Yourself."
"I’m a Numbers Guy. And I Believe I Understand Rob’s Thesis, that Future Returns, Over the Next Decade, Have a Tight Inverse Correlation to the PE10 for the Starting Point. Remember, Correlation Doesn’t Need to be 100%, Only That There’s a Bell Curve of Potential Outcomes that Shift Meaningfully Based on the Input."
"What a Difference a Threat to Get the Father of Two Small Children Fired From His Job Has on an Investing Discussion, Eh? Long Live Buy-and-Hold! It’s Science! With a Marketing Twist!"
"I Respect Rob and His Analysis. He's Bright, Energetic and Passionate. [The Goon Stuff] Is Really Nonsense. I Enjoy a Thought-Provoking Conversation With People I Respect."
"The Fact that Shiller is a Proponent of the Approach Takes it from a Fringe View to Mainstream, in my Opinion."
"I Have had Academic Researchers Tell Me That They Dream of the Day When They Will be Able to do Honest Research Once Again. I Have had Investment Advisors Tell me That They Dream of the Day When They Will be Able to Give Honest Investing Advice Again."
"Let’s Call a Spade a Spade, Shall We? Wade Pfau Stole Your Research and Put His Name on it, Throwing You Just a Tiny Crumb of Acknowledgement to Ward Off a Lawsuit. He’s Profiting Handsomely By His Theft, Leading a Charmed Life, Widely Published, Widely Respected. While Rob Bennett Continues to Toil in Total Obscurity. It’s So Incredibly Unfair, I Think If It Happened to Me, It Could Actually Drive Me Insane."

I’ve posted Podcast #137 to the “RobCasts” section of the site. It’s called Nine Valuation-Informed Indexing Portfolio Allocation Strategies.
You could follow a cliff approach to changing your stock allocation in response to price changes. Or you could follow a gradual approach. Or you could follow the model suggested by Benjamin Graham. Or you could….
