00:01.600 --> 00:08.800
In this next video we will examine and create the equal weighted index and the idea behind it is pretty

00:08.800 --> 00:12.360
simple so all constituents in the index are equal weighted.

00:12.490 --> 00:19.210
And that means equal weighted in monetary terms and actually the intuitions that we invest equal dollar

00:19.210 --> 00:21.490
amounts into each constituent.

00:21.580 --> 00:28.370
So the easiest example is to have only two constituents and a total investment sum of two thousand dollars.

00:28.390 --> 00:35.460
Then we invest 50 percent of our investment sum into a stock A and 50 percent to stock B.

00:35.530 --> 00:40.990
So let's have a look at an easy example with some numbers and it's actually here the same example as

00:40.990 --> 00:41.970
before.

00:42.010 --> 00:44.230
So we have two timestamps and two stocks.

00:44.230 --> 00:46.960
And here we have the prices.

00:46.960 --> 00:51.400
And then we can also create uh the uh simple returns.

00:51.460 --> 00:57.550
So of course we fear a timestamp zero no returns and also no weighted average return.

00:57.730 --> 01:01.160
And the base value of our index shall be 100.

01:01.270 --> 01:08.110
And then we calculate the returns for the period from timestamp 0 to 1 and it's 60 percent for stock

01:08.110 --> 01:15.460
A and minus 20 percent for stock P and then we have to calculate the weighted average return of stock

01:15.490 --> 01:16.520
A and B.

01:16.630 --> 01:22.660
And as we have equal weighting and an equal weighted index then consequently we have to wait the returns

01:22.660 --> 01:27.450
of stock A and Stock B with the 50 percent or O point five.

01:27.760 --> 01:33.130
And we get a weighted average return for that period of 20 percent.

01:33.130 --> 01:40.060
And finally starting with an index value of 100 and having 20 percent return and the first period gives

01:40.060 --> 01:45.250
us an index value at the end of the first period of 120.

01:45.280 --> 01:53.920
So we simply multiply 100 by one plus 20 percent so that's how we calculate the indexed value at the

01:53.950 --> 01:55.420
time stamp on.

01:55.510 --> 02:00.370
And now let's go to a more general example with more periods.

02:00.370 --> 02:05.810
So we have two periods so here we have in addition the timestamp too.

02:05.990 --> 02:13.770
And still we have the returns here and again our base value at the time stamp zero should be 100.

02:13.820 --> 02:19.970
And now for the period from timestamp bond to timestamp 2 we have a return for stock a of minus 10 percent

02:20.300 --> 02:26.030
and a return of 30 percent for stock B and therefore a weighted average return for that period of 10

02:26.030 --> 02:27.320
percent.

02:27.380 --> 02:32.620
And as you can see here we have an additional column cumulative investment multiple.

02:33.140 --> 02:39.020
And for the first period the cumulative investment multiplier is simply the return of the very first

02:39.020 --> 02:45.260
period 20 percent plus one gets on point two and by multiplying one point two.

02:45.260 --> 02:53.040
With the initial index value 100 gives us the 120 and let's go on and calculate the cumulative investment

02:53.040 --> 02:56.480
multiple and the indexed value for timestamp 2.

02:56.490 --> 03:01.280
And the calculation of the cumulative investment multiple is pretty straightforward.

03:01.290 --> 03:07.410
So we have two periods and then one period we have 20 percent return average and a one period 10 percent

03:07.890 --> 03:14.590
and the cumulative investment multiple is simply one plus 20 percent times one plus the 10 percent gifts.

03:14.700 --> 03:16.930
Uh one point uh three two.

03:17.490 --> 03:23.880
And by multiplying the cumulative investment multiple with the initial indexed value one hundred gives

03:23.880 --> 03:29.880
us actually the indexed value at the time stamp to one hundred thirty two.

03:30.600 --> 03:37.320
And lastly if I look at the pros and cons of the equal weighted index and one main advantage of the

03:37.320 --> 03:45.040
equal weighted indexes so that by definition the equal weighted index shows a maximum degree of diversification.

03:45.120 --> 03:52.640
So we have no concentrated positions as our constituents have the same rate and second also the equal

03:52.640 --> 03:55.030
weighted index is pretty intuitive.

03:55.370 --> 04:00.620
So we have an equal investment amount invested in each constituency.

04:00.720 --> 04:04.530
And now let's go also to the disadvantages.

04:04.670 --> 04:10.830
So typically the performance of the equal weighted index is biased towards the smaller stocks as smaller

04:10.860 --> 04:16.760
stocks have a higher proportion or higher weight in the equal weighted index than they would have in

04:16.760 --> 04:19.310
a price weighted or evaluated index.

04:19.460 --> 04:24.770
And typically smaller stocks show higher risk but sometimes also higher return.

04:24.830 --> 04:33.530
So typically an equal weighted index is riskier riskier and also here the market capitalization better

04:33.530 --> 04:36.230
reflects a company's economic importance.

04:37.420 --> 04:44.080
And another point is that typically the equal weighted index does not reflect typical portfolio construction.

04:44.110 --> 04:49.510
So investors rarely invest equal amounts and to constituents.

04:49.510 --> 04:51.380
And finally and this is a big point.

04:51.370 --> 04:59.320
An equal weighted index or a portfolio that follows an equal weighted index requires constant rebalancing.

04:59.320 --> 05:06.040
So let's assume that we invest a 100 dollar in stock a 100 dollar and stock B and in the first period

05:06.070 --> 05:11.650
the price of stock a increases and the price of stock B decreases.

05:11.650 --> 05:16.130
So in this case the rates are actually no longer 50/50 or equal.

05:16.520 --> 05:22.110
And we would be required to rebalance so we as sell winners and buy losers.

05:22.220 --> 05:26.980
And this means actually high transaction costs and also Texas.

05:26.980 --> 05:32.920
So from a practical point of view the equal weighted index is actually not the best choice.

05:33.100 --> 05:37.390
And with this we are finished here and I hope to see also in the next videos by.
