but i am still mystified by the total return 10 year Aic Stats for Global sector.
The difference in returns for the two periods 10 years up to 30th Nov 2018 and 10 years up to 29th Dec 2017 is 209%, now there are only two 11 month periods which are not shared by those two 10 year time spans, one is 30th Dec 2017 to 30th Nov 2018 at this end and 29th Dec 2007 to 29th Nov 2008 at the back end. The Aic Global sector fell a few percent in the 11 month period at this end which must mean that the entire 209% difference plus a few percent more for this year must be accounted for in the 11 months 29th Dec 2007 to 29th Nov 2008, a period when the MSCI World index fell 40%. ? It does not seem credible that the Aic Global sector fell over 200% back in 2007/08 so why the big difference?
It's not only not credible that it fell over 200%, it's impossible, as stock/IT prices don't go negative. The maximum fall possible is 100%, to zero.
Also, in regards to the difference in return between the two periods being 209%, no, not really. %age returns are geometric, not arithmetic, and so you can't usefully subtract % returns from each other -- a return of 100% means doubling your money, 200% tripling, but the end difference between the two periods is not three times as much.
One was 154% and the other 363%, so for each £1 invested you'd have ended up with £2.54 and £4.63 respectively, and the latter is 82% more than the former, not over three times as much.
And don't forget that a 40% fall requires a 66.6% gain to recover to the same level, however I'm not at all sure the MSCI World is a useful comparison for the AIC Global sector when you consider the sector includes stuff like Scottish Mortgage, BMO Smaller Cos, Lindsell Train, Law Debenture and plenty of other "non-MSCI World type" ITs.
Happy New Year
