Planned Features
4
· cost estimate by index vs. NAV regressions (so far only for a couple of funds)
· enable long-short portfolios? zero overall allocation has to be treated, e.g., by adding the risk-free return to the portfolio for further analysis

· section for European funds/indices
· bonds
· alternative assets (carry, trend, ....)

=> to do this, the expected return calculation has to be built on top one large correlation matrix, list of returns, and list of volatilites

a brief explanation for this tab
6
User InputsSettings
→ choose the factors used in the FF6 regression
→ decide whether you want to include the intercept/alpha in the expected return calculation
→ choose a custom start date for the regression, e.g. to look at the same periods for indices/funds with different inception dates
7
Portfolio Allocationrisk-free
→ calculated automatically according to the other allocations; if negative, cost of leverage is considered
8
DM
→ allocation to DM funds/indices (green area)
→ information given: fund costs, correlation to portfolio, links to relevant RR community discussions, brief comment about methodology and what to expect going forward
9
EM
→ allocation to EM funds/indices (green area)
10
bonds→ TODO
11
OutputsReturn estimate
→ for the whole portfolio
→ extra info: excess costs over MCW, premium over MCW, ....
12
Portfolio statistics
→ based on historical index/fund data
→ based on backtested factor exposure since ~1990
13
DM regression
→ regression results of the chosen DM portfolio scaled to 100% equity
→ FF6 with custom choice and FF3
→ expected premium and volatility estimates
14
EM regression
→ regression results of the chosen EM portfolio scaled to 100% equity
→ FF6 with custom choice and FF3
→ expected premium and volatility estimates

Fund Costs
brief explanation of our 'methodology'
46
→ overview over the fund costs in the past years based on annual report data
→ costs include TER/OCF/management fee, dividend and capital gains WHT drag, transaction costs (only comissions), security lending income
→ OCF reductions are considered for the cost estimate going forward
WIP: include fund vs. index regressions for another cost estimate

AbbreviationsSome Rudimentary Explanations (to be expanded – please read the RR topic for more and ask questions there)
54
MCW: market-cap weighted
Costs
This figure is the estimated fund costs, in two flavors.
55
LC: large cap
1) For years with available annual reports, we have averaged (relative to AUM) transaction costs, withholding tax drag, capital gains tax drag and security lending income. Then, this historical cost is added to the current OCF.
56
MC: mid cap
2) The live fund returns (NAV) are regressed against the net index. Difference to 1): This includes spreads, but not WHT (since it's contained in the net index approximately).
57
SC: small cap
58
ERP: equity risk premium
Expected premium
This figure is the expected return over the risk-free rate. Comes also in two flavors, arithmetic and geometric return: https://www.investopedia.com/ask/answers/06/geometricmean.asp
59
- geometric return is what you should care about
60
for many more, see RR community
- arithmetic return is more of a computational variable (is higher, but a 'theoretical' value without volatility decay)
