Statistics And Other Math Dispersion Correlation Coefficients Normal Distribution
Normal Distribution (Bell Curve) Gaussian distribution needs only two parameters to describe – mean, and variance 68.26% of observations fall w/in 1 standard deviation of the mean 95.44% w/in 2 standard deviations of the mean 99.74% w/in 3 standard deviations of the mean

Assuming Returns Are “Normal” Financial software assumes that investment returns are normally distributed around a mean, or average, return (9% for Large Cap Stocks, per SBBI through 2007) This assumption is made because it is true – usually.
The Flaws of Return Estimates(Why Returns Are Not Always “Normal”) Returns are not independent of each other Returns can be “clustered,” as individual returns are influenced by the same outside variable Dispersion renders return estimates unusable
Volatility Clustering Returns are not independent, they rely on underlying economic events and trends These trends can occur over long periods Tech Bubble Tech Bust 9/11 Recent Credit Crisis Central Bank Actions
Returns Gain Momentum(not independent) Most days on equity markets are marked by small, incremental changes. Large percentage changes, however, tend to be followed by large changes. This is called “volatility clustering”, indicating that exceptional volatility happens in sequence.
True Distribution of Returns Instead of being Gaussian, or Normal Curve, investment returns fall along a Cauchy Distribution, which exhibits a higher mean, less observations along the curve, and “fat tails”.

Impossible Market Days Chance of August 31st, 1998 – 1 in 20mm Chance of the 3 declines in August 1998 – 1 in 500mm Chance of October 19th, 1987 – less than one in 10 to the negative 50th power, a number that does not occur in nature
What We Know AboutMarket Risk “Average Return” is poor guide of what will happen – variance and standard deviation too great Returns are not “Normally” distributed, instead the distribution has “Fat Tails” Returns are not Independent, there is clear evidence of clustering of returns
Markowitz Sticks by His Theory Those who say a normal distribution shouldn't be used "don't know what they're talking about," said Harry Markowitz, the developer of MPT, who now runs an eponymous San Diego consulting firm. "If the probability of distributions [on a portfolio] is not too spread out, from a 30% [loss] to a 40% gain," it's OK to use a normal curve, he said. • Modern portfolio theory may face more skepticism • By Dan Jamieson March 10, 2008, Investment News
Investing is Riskier Than Commonly Described Because investment returns exhibit “fat tails”, the extreme observations or returns are more likely than we would assume. We value loss more than we value gains (2x). These two facts together mean that investing in equities is much riskier than we normally describe.
The Human Model of Forecasting “We won’t have recessions anymore” “It’s a soft landing” “Things are so bad they will never improve” Source: H.S. Dent graphic interpretation of data in 2002 Schweser CFA Study Program, Chapter 15, pp 144-45.
Investing Is NEVER Satisfying We tend to estimate what will happen based on most recent experience When our accounts are up, we compare to others (relative income hypothesis) When our accounts are down, we feel greater loss because we value loss at 2x gains
It’s Hard For Us To Stay True to a Model, Even Mr. Markowitz “Mr. Markowitz was then working at the Rand Corporation and trying to figure out how to allocate his retirement account. He knew what he should do: ‘I should have computed the historical co-variances of the asset classes and drawn an efficient frontier’... But, he said, ‘I visualized my grief if the stock market when way up and I wasn’t in it – or if it went way down and I was completely in it. So I split my contributions 50/50 between stocks and bonds.’” Can We Turn Off Our Emotions When Investing? Joe Nocera, 9/27/07, NYT, quoting Jason Zweig’s book, “Your Money & Your Brain” (Simon & Schuster)
Investors Already Knew This Even though the return data of the last 82 years shows that large cap stocks return, on average, 9%, investors and advisors are never surprised when their personal experience is something other than 9%. Why? Because everyone knows intuitively that the average is not instructive on what will happen next. It is so unreliable as to have no predictive value. And yet it is the basis of all financial software.
Sequence More Important Than Average The order in which your returns are earned is more important than the overall average. Consider a worker who saves over 30 years. If the worst 5 years of the whole period are at the end, it is significantly different than if the best five years are at the end. It is all in expectations.
