In short, plug in the historical average. Early on in this discussion I took a quick look at some of the 3, 5 and 10 year volatility measures on M* for a few funds, and saw big differences, I am more confident that volatility persists than that the average level of returns or trendiness persists. The Sharpe Ratio,Journal of Portfolio Management,Fall 1994, 49-58. Source
In general, volatility estimates should be computed with the highest frequency data available, at least daily.Suppose for a 5 year period, the annual return averaged 6% with standard deviation of only Free resource > P1.T1. medoo framework in WP plugin Is it unethical of me and can I get in trouble if a professor passes me based on an oral exam without attending class? This means that if you repeatedly sample the returns and compute the sample mean of each sample, you will get a normal distribution of sample means as estimates of actual average http://www.analystforum.com/forums/cfa-forums/cfa-general-discussion/9939876
This book will expose students to the notion of data checking and make them aware of problems that exist when using real-world data. My monthly returns going back through 2013 don't vary much at all. Ditto for daily returns.If you run an asset class backtest for one year with PortfolioVisualizer, the SD is listed as N/A, as it should be: Backtest Portfolio Asset Class Allocation.In your To the extent that variance increases as the square of the holding period, multiplying the variance of the returns for a set of shorter holding periods will be indicative of the

These deviations will cause return differences that ultimately get picked up by the tracking error measure. Let’s return to our above example, except this time, assume an incredibly skilled manager Tracking Error Calculation Monthly Returns This means that if you repeatedly sample the returns and compute the sample mean of each sample, you will get a normal distribution of sample means as estimates of actual average
And I'll fully admit the differences between actual stock returns and the idealized model are worse than many other things statistics are applied to.

Tracking Error Formula Cfa This simple observation pretty much disproves the validity of using annualized SD of monthly returns for only a few years as representative of the actual standard deviation of annual returns over
I have a black eye. this contact form And such daily move (point move or cumulative effect) is what stirs strong emotions, and may lead to investment mistakes, much more than the annual changes. Finally, I think you meant to multiply (not divide) the standard deviation of the individual heights by sqrt(20).Correct, I should have been more precise and the sum is probably the better Mandelbrot for one would suggest this is not true for stock returns.

Or you could approximate the SD of 5-year total returns by multiplying the SD of annual returns by SQRT(5).These approximations are based on the principle that variance of returns should theoretically
But then again, if you've been personally investing for a year or two, I think knowing how your annualized mean and standard deviation of returns compares to historical annualized returns of I don’t think that’s correct, cause if you annualize to get the returns, then you will only have 5 year of annual return and you get the STD of that will The residual return of a portfolio corresponds to the share of the return that is not explained by the benchmark."—Amenc page 114.

So the end formula essentially incorporates annual returns, but uses algebra to avoid the intermediate step of computing the annual returns explicitly.I would think that annual returns are of general interest, Finally, I think you meant to multiply (not divide) the standard deviation of the individual heights by sqrt(20).
