Logically, of course, the only way to satisfy this request is to never read a livesoft post.

And with your XIRR spreadsheet, what answer do you get? Is it different? The same? This exercise is a control of your spreadsheet and your calculator.

oh, phew. I thought it was a control of my mind.
calculator says 1.65%
XIRR says 3.36%; I would calculate the YTD return as follows (1.0336)^.5= 1.67%
alternatively, use 12/31/15 for the ending date rather than 6/30/15, and get 1.65%.

* It usually doesn't make much sense to look at the internal rate of return during sub-periods (like YTD), as it is uncomparable. It is best to look at this investor return over the entire investment history, to see how the investor has been doing overall.
What one usually wants to calculate, for YTD, is a portfolio return. Other names for it are time-weighted return and comparable return. This rate of return is comparable to the YTD return of an index.
Investor and portfolio returns can significantly differ (depending on the specific timing of contributions and withdrawals). So, the distinction between them cannot be dismissed as unimportant.
In a thread like this one, I would think that it would be more appropriate to report YTD portfolio return (time-weighted return).
letsgobobby wrote:Now you are trying to play with my mind...
What does it say about XIRR? It says use 12/31, or calculate your YTD return at the halfway point by using 6/30 and then adjusting with the method I showed.
My YTD is 3.88-4.00%, depending on precisely which date I use (I am using 1/5/15 because that's the date for which I have a year end 2014 total). So I think that's right. I have 10% VSS and 28% Total International so that probably helped.

By starting on 1/5/15, you have removed the 1% drop in the markets in the first few days of the year. This automatically makes your portfolio performance 1% better than others who reported portfolio performance starting on 1/1/2015.

I think that's only true if you shred your year-end statements or delete them from your online accounts without reading them.

I guess I'm just confused by the point you are making about comparing to the return on an index. I must be missing something.
Here's an extreme example just to illustrate the difference between XIRR and portfolio returns, and comparing them to an index.
- I invest $1,000 in security A.
- One year later, security A loses half of its value. Portfolio value: $500.
- At that point, I invest an additional $1,000 in security A . Portfolio value: $1,500.
- One year later, Security A recovers its initial value. Portfolio value: $3,000.
XIRR answers the question: Had I put my contributions into a savings account (on the same dates), instead of into security A, what annual interest rate would have been needed so that I end up with $3,000 at the end of the second year? The answer is: a bit more than 30%. So, XIRR will report this number*.
* To check this: After one year, $1,000 grows (at 30%) to $1,300. After contribution, that's $2,300. After another year, this grows (at 30%) to $2,990 (almost $3,000).
Yet, you and me know very well that the return of A, over 2 years, was 0%; it lost half of its value in the first year and recovered it in the second. Had I lump invested $2,000 in A and let it ride for 2 years, the final value would have been $2,000.
So, which of 30% or 0% is the valid return? It depends what you want to talk about!
If you want to compare A to the S&P 500, you'll say that the return was an annualized 0% over the 2-year period. If you want to describe the growth of the investor's money, it was an annualized 30% growth, but you have to understand that this impressive growth was simply due to the timing luck of the contributions.
Another investor investing his money in A over the exact same period, but making different contributions on different dates would have most probably got a completely different investor return (XIRR). But, he would have got the exact same portfolio return. As both investors had identical portfolios, it makes sense for their comparable returns to be identical. That's what the portfolio return gives you.

Suppose one bought 1000 shares of a fund on December 31, 2014 that closed at $24.08 a share. And then one made no other purchases through 6/30/2015 from the outside, but one did reinvest the dividend of $241 (0.241 per share) on 6/26 at $24.52 a share, and the fund closed at $24.24 a share on 6/30/2015.
What would one's YTD return to 6/30/2015 be?
DR wrote:It seems that you are just explaining what an internal rate of return means. I get that. You can use the XIRR function to figure both YTD or the annualized return depending on how you build the formula in Excel (i.e., whether your use 365 days or the number of days YTD). You can also use XIRR function to give an annualized return over several years. If you have a portfolio of 10 different positions, you can also use XIRR to figure out the YTD or annualized return (either one) on that entire portfolio. It sounds like you may be using the term portfolio in a different way than I was.

I believe it's higher because the mid-year dividend cash flow has a larger present value than if included in the terminal value on 12/31/2015.

The shares purchased with the dividend lost money because they were purchased at a higher price than the closing NAV on 6/30/2015.

In my vocabulary:Is that clearer?
- XIRR = investor return = money-weighted return
- comparable return = portfolio return = time-weighted return
I use the same idea as in studies comparing "investor returns" to "fund returns".
Do you have more intuitive names to suggest?

This is another possible case of weird math. The first fund has returned about 1.23% and the second fund has returned about -0.2% for the 6 months of the year. How one could get 5+% out of those two funds is only possible with phenomenal market timing.
OK, contributions could have made one's portfolio 5% larger, but that is not return on investment.

I will think of portfolio return as "where I actually am so far" and investor return (XIRR) as "who knows, at the rate I'm going, maybe I'll be here after twelve months."

Guilty as charged (phenomenal market timing). What can I say I got lucky. Pure luck and I know it won't happen again. Slow and steady at 60/40.

For laziness reasons, the spreadsheet currently computes an annualized investor return, regardless of history length, even when history length is 11 months or less. Usually, for periods of less than one year, it should report cumulative returns (not annualized); this would have required putting conditions in the spreadsheet formulas, and I didn't get do it yet.
I'll fix it.

I hope you don't, if you haven't already. I was just thinking out loud. It makes perfect sense as it is, with the explanation.
