#38054 RE: SFSecurity #38049

Could you please identify each of the sectors next to the figures? Also, do you know how they compare with equivalent US sectors?


No sorry, that data (spreadsheet) is now gone. These figures are for quarterly figures (note july 2008 is missing) and I suspect would provide somewhat similar figures to the ones I posted earlier

Total Return 'index' figures for FT All share index and FT sectors
Date, FT All Share Index, Oil/Gas (Energy), Basic Materials, Industrial, Consumer Goods, Health Care, Consumer Services, Telecoms, Utilities, Financials, Tech

do you know how they compare with equivalent US sectors?


Whilst the figures would most likely differ, its the common pattern that matters.

Typically with any set of stocks/sectors that comprise a 'Index' each year you'll see most cluster quite closely around the average and a much smaller number of outliers that either make a big up (gain) or a big down (loss). Often volatility clusters i.e. a stock that drops a lot one year might rebound a lot the next year.

When you centre the figures around the average gain you eliminate the general rise (or decline) of the market and are looking purely at relative moves. i.e. sector gain / average of all sectors gain. Left as-is and those outliers induce a negative bias. Up 20% one year down -20% the next = 0.8 x 1.2 = 0.96. When you equal weighted and yearly rebalanced pairs of such assets that loss is mitigated - such that you gain by not losing so-to-speak, i.e. equal weighting the left and right tails is more inclined to yield no loss rather than a loss where no rebalancing is performed.

0.5 in a 0.8 loss
0.5 in a 1.2 gain
1.0 overall result (no overall loss). (Compared to 0.8 x 1.2 which yields a negative -4% loss).

i.e. equal weighting/rebalancing the left and right tail extremes reduces the losses that otherwise would be compounded into the total overall portfolio gain/loss.

Of course you can't predict which sectors (or stocks) will be the left or right tails in any one year in advance, so you have to equal weight all sectors (stocks) to ensure that is the case. But broadly you don't need to reset all of the set back to exact equal weightings each year and can just adjust the more extremes only (reduce the best, add to the worst). Similarly you might assume that all sectors will over the longer term tend to produce somewhat similar rewards, otherwise investors would just invest in the best single sector alone. In practice one sector will likely be the more regular winner and another the more regular loser such that over time one sector does produce a good reward and another a bad reward, but again that's unpredictable in advance.

AIM of sectors is one such method to rebalance such patterns tending to sell the most stock in the best performer, add more stock to the most worst performer. For instance FT All Share gains 2008 onwards has annualised around 6.8% since April 2008, whilst AIM/equal weighting yielded around 11.2% annualised, with around 2.7 average trades/year (16 buy/sell trades in total over the 6+ years).
