Myth Buster11:07

Risk Aversion Also Includes Fear of Missing Out

Risk aversion is usually framed as fear of losing money, but Rotblut says it also appears as fear of missing gains enjoyed by others. The same emotional mechanism can therefore produce both panic selling and greedy performance chasing across recurring boom-and-bust cycles.

  • Risk aversion is not limited to fear of losses
  • Watching others profit can provoke reckless participation
  • Greed and panic are related emotional responses
  • Market narratives recur even when industries and technologies change

“risk of version means I'm afraid to lose money, but it also means you're afraid of not making money when you see everybody else making…”

Charles Rotblut · 11:13

“it's just human nature.”

Dividend Stocks Are Not a Direct Substitute for Bonds

Dividend stocks can supplement retirement income, but Rotblut distinguishes their role from the safety function of bonds. Bonds and cash-like assets protect short-term needs and provide funds for buying during declines, while dividend stocks retain equity risk despite their income.

  • Low yields do not eliminate the protective role of bonds
  • Bond ladders and maturity-date funds can manage rate uncertainty
  • Dividend stocks can supplement rather than replace safe assets
  • Reinvested dividends can compound equity ownership

“you're not getting paid any interest, but you're also not going to lose any money.”

Barry Ritholtz · 20:02

“investors need to view bonds as this is what I want to use for safety, to protect my short term assets”

Individual Investors Cannot Win a Millisecond Trading Contest

Equal access to information does not mean individuals should compete directly with high-frequency traders. Rotblut recommends exploiting different advantages: patience, discipline, a broad stock universe, and the ability to pause before submitting an order.

  • Institutional scale limits access to very small companies
  • Individuals can research stocks ignored by major institutions
  • Speed cannot overcome a technological disadvantage measured in milliseconds
  • Slowing down supports deliberate decisions

“I always encourage investors to just go slow, you know, put your trade order in, step up, take a deep breath, and just think about…”

Charles Rotblut · 47:45

“You have to play a different game exactly.”

Why Valuation Metrics Need Economic Context

The discussion challenges mechanical use of long-term valuation ratios such as CAPE. Rotblut argues that valuation conclusions depend on assumptions about earnings, revenue growth, and the interest-rate environment, while simpler measures such as price-to-earnings, price-to-book, and price-to-sales remain accessible to individuals.

  • Earnings and revenue growth affect whether current prices are justified
  • Interest-rate regimes influence reasonable valuation levels
  • A metric can remain historically elevated for many years
  • Simple valuation ratios are easier for individuals to obtain and compare

“Obviously, the big question is do we get earnings and revenues growth?”

Charles Rotblut · 14:19

“the pe is just good because it's so easy to find and it's just out there.”

Stress Can Make Even Professional Traders More Risk-Averse

The episode describes research in which increased stress hormones changed the behavior of professional traders. This supports the broader behavioral-finance finding that people feel losses more intensely than equivalent gains and may alter risk decisions under pressure.

  • Professional expertise does not remove biological responses
  • Higher stress can increase risk aversion
  • People work harder to avoid losses than to obtain equivalent gains
  • Emotional state can affect financial judgment

“as the stress hormones were raised, these traders who are professionals, became more and more risk adverse.”

Charles Rotblut · 23:29

“we're risk adverse and we'll pretty much do everything we can to avoid occurring losses.”

Why AAII Refused to Expand Its Long-Running Allocation Survey

AAII's monthly survey asks members how much they hold in stocks, bonds, and cash. Although people have requested categories such as gold, real estate, and commodities, the organization preserved the original questions to protect a stable historical record that can be compared across decades.

  • The survey covers stocks, bonds, and cash
  • Its methodology has remained stable for decades
  • Adding categories would disrupt historical comparability
  • AAII created the survey to give individual investors a direct voice

“we have this history that's been pretty stable that we can now compare it against, so to update it, we'd lose all that long term…”

Charles Rotblut · 16:26

“Let's give our members a voice.”

How Private-Business Valuation Shaped Rotblut's Investing

Rotblut entered finance from journalism and advertising after joining a small-business valuation firm because he knew Excel. Working directly with closely held companies taught him to examine cash flows, operations, and defensible valuations before he later moved into investment research and education.

  • Rotblut's degree was in journalism rather than finance
  • Excel proficiency opened his first finance opportunity
  • Closely held businesses required hands-on operational analysis
  • Court-defensible valuations encouraged analytical rigor

“my degrees in journalism, worked in advertising for six years”

Charles Rotblut · 34:13

“there's something about I think working on that private side where you're really being hands on and really look at these small businesses, understanding how…”

Q&A· 1

Q&A26:25

Should an Individual Investor Choose Active or Passive?

Rotblut rejects a universal answer to the active-versus-passive debate. Passive investing is appropriate for people who lack the interest or time to research securities, while active investors need a credible reason to expect better returns or income and may find opportunity beyond heavily covered large companies.

  • Passive investing suits people who do not want ongoing research
  • A passive portfolio should serve as the active investor's benchmark
  • Active management must justify its extra effort
  • Less-covered stocks may offer a different opportunity set

“if you have no interest, you just don't want to spend time on it. Too passive and really passive investing should be your benchmark.”

Charles Rotblut · 26:41

“Can you do better? Can you get more return and more income?”

Why Fractional Shares Matter for Dollar-Cost Averaging

The episode contrasts traditional mutual funds with ETFs for regular investing. Mutual funds can accept an exact cash amount and issue fractional shares, while whole-share ETF purchases may leave small cash balances uninvested, though the practical difference depends on the brokerage setup.

  • Mutual funds can issue fractional shares
  • Whole-share ETF trading can leave residual cash
  • Repeated idle balances may accumulate over time
  • The best vehicle depends partly on how contributions are invested

“if your dollar cost averaging A mutual fund works better just because you can buy this fractional shares”

Charles Rotblut · 27:49

“your entire money goes into worth an E T F. Uh. You know, if you have an et F and I RA, maybe you have…”

Investment Success Starts With Avoiding the Big Mistakes

Rotblut argues that investors do not need extraordinary predictions to improve their outcomes. Avoiding panic sales and other major behavioral errors can create a substantial advantage because selling during a bear market locks in losses and often leaves investors sidelined during the recovery.

  • Avoiding catastrophic errors matters more than finding perfect trades
  • Panic selling converts temporary declines into permanent losses
  • Investors who exit in fear often remain out too long
  • Behavioral discipline can provide a durable advantage

“if you want to make a lot of money in the markets, just don't screw up.”

Charles Rotblut · 07:53

“they basically lock in losses and miss out on the chance to recoup those losses.”

Retirement Portfolios May Need to Last 30 or 40 Years

Recency bias encourages investors to focus on immediate headlines instead of the lifespan of their portfolio. For someone retiring around 60, the relevant planning horizon may extend another three or four decades, and surviving to an older age can further increase remaining life expectancy.

  • Immediate news distracts investors from lifetime goals
  • Retirement can require decades of continued portfolio growth
  • Life expectancy changes after reaching later ages
  • Longevity materially affects required retirement resources

“they just succumbed too often to recency bias versus thinking I have this portfolio and it needs to last for the end of my life”

Charles Rotblut · 24:49

“if you're a ter at sixty nowadays, you can be looking at thirty or forty years more of life”

Plain-English Communication Is an Edge in Finance

For new finance professionals, Rotblut prizes the ability to make complicated ideas understandable without jargon. The skill applies across analytical, editorial, and client-facing roles, opens career opportunities, and remains transferable when finance employment contracts.

  • Complex ideas should be expressed in concise everyday language
  • Many technically capable professionals cannot communicate clearly
  • Plain-English explanation is valuable across finance roles
  • Communication skill remains useful outside finance

“figure out how can you explain things asn't simple and asn't simple English as possible.”

Charles Rotblut · 49:24

“the ability to just communicate these very complex concepts and very simple, concise language that alone is invaluable.”
