[PLEASE SEE MY BELOW RESPONSE(S) AS WELL]
Since so many on these boards have difficulty with percentages, I did a show-you-better-than-I-can-tell-you type of thing. I ran your daily percentage calculation in a simulation spreadsheet to simulate your figure over 365 days. Here are the results:
Final after 365 days: $365,438.64
Even using your numbers, the answer is still well over 361%:
$365,438.64 / $10,000.00 = 36.54386415
convert to percent: 3654.386415 %
Since some readers may still not understand how the "convert to percent" works, I've simplified that as well through example:
If someone goes from $100 to $400, what is the percentage increase? Well, the gain is $300 (400-100). Then, as you did in your post, divide the gain by the initial value: 300/100. Or 3. But, that's not 3%! You have to multiply by 100 to get the percentage, or 300%!
So, using your slightly off numbers, I'm doing even better: 3,654.38%
I've attached the actual spreadsheet for verification or educational purposes, but here are the top and bottom clips of it:
If needed, I can try to explain it further:
UPDATE: I forgot to subtract the initial $10 grand from the final sum of $300 grand, doing that, the corrected APR (That your daily percentage would have yielded) is 3,554.38%!
...Going to go over the sheet closely this weekend. I'm thinking my percentage change should be +3.16
on par with the accuracy of your current ARP :laugh:
"...thank you sir for enlightening me"
How'd I do?
If your comparison is accurate, I can stop here and you should be able to extrapolate the rest of my response :laugh:
lol, it's a great tool, that's why the industry uses it. The volatility comes from not having many days from which to calculate it. As time goes on, and approaches 365 days, it stabilizes more so.
So, basically, any measuring stick would be volatile with only a few days (20, in this case) of data. But it's the best ruler we've got.
Even so, everyone in the challenge is subject to the same exact volatility. soooo ... it is what it is.
ps..."invalidates the mathematics"???:blink: 1. Math is the universal language. It's the reason why we can communicate remotely like this.
2. What do you use whenever you find that Mathematics has been invalidated by your opinions?
fair enough; Didn't realize the compounding made such a massive difference but it certainly makes sense at such high percentages.
Still don't think its useful tool to gauge performance tho. I think the volatility of day-to-day returns invalidates the mathematics.
i think there is something else wrong with your spreadsheet too, because my number is red, and it's supposed to be green. fix that will ya?
Its quite possible I missed something, but it looks like your annualized rate of return is way off...
Did you start with $10k?
if so, youve made $1981.54... which is 1981.54/10000 = 0.198154 = 19.8154% so far.
You have 20 days in the challenge, so thats 19.8154%/20 = 0.99077% a day.
That extrapolated to 365 days would be 0.99077 * 365 = 361.6%, not even close to 2609%. 2609% means you're making 7% a day

...
It’s a fairly simple calculation to perform as long as you have the following information:1. Number of days that have elapsed so far this year. This is easy to calculate if you have access to Excel.
2. The YTD return of the investment that you want to annualize.
The formula for annualizing a ROR is pretty straight forward:
[(1 + YTD ROR)[SUP]1/(#of days/365)[/SUP]] – 1
