Yesterday we celebrated our first anniversary and mentioned that we are going to make the asset screening as automatic as possible. But it is a long (or at least mid) term project but time and tide wait for no man. Thus we made for you a manual pre-screening of about 600 ETFs that can be traded on NYSE or NASDAQ via DeGiro without broker fees (except the so-called modality payments, which are though negligible).

One year ago we launched letYourMoneyGrow.com and we already can report some achievements!
1. We have created and keep developing our Quantitative Toolbox. In particular, you will not find suchlike Option Calculator with scenario simulation or mortgage calculator with estimation of the interest rate risk anywhere else.
2. Thanks to Einstein, we disproved the stupid mantra that allegedly "nobody can be better than the market". On the other hand we have shown that many "solid" institutional asset managers and [self-proclaimed] stock market "gurus" cannot beat the market. Thus, only track record matters!
3. We have demonstrated, first of all by the example of IREX, how a quantitative performance analysis can help by investment decisions. At least in case of IREX it was clear that the guy will fail and he recently did!
Our next big goal is to automatize the asset screening as much as possible. Continue reading "letYourMoneyGrow.com is one year (and one day) old!"
Many investment funds and financial services that want your money argue with a deferred capital yield tax. For instance, in Germany if you trade by yourself, you immediately pay the capital returns tax [Kapitalertragsteuer] (unless the net result of your previous trades is negative). But if you invest in a fund, you don't pay the tax on returns until you sell your share (you still pay a tax on dividends).
We show that though, in general, an investor profits from tax deferral, one should not exaggerate its effect. Moreover, due to annual tax-exempt amounts [Jahresfreibetrag], an immediate taxation can be better than a deferred one.

Friends of mine ask me why I don't trade the Bitcoin and other cryptocurrencies. Finally, it does not matter what to trade as long as one can make a return. The reason is that indeed I hardly can, since:
1. Contrary to [German] stocks, I don't have such a deep knowledge of cryptocurrencies.
2. Enormous volatility of Bitcoin makes the re-investment of winnings virtually impossible, so one can achieve only linear, not an exponential growth by active trading.
3. I have a strong allergy when something clearly resembles a tulipmania or a Ponzi scheme.
4. Theoretically a blockchain cannot be forged but in practice there are implementation bugs. And technical limitations (which recently might have caused the split of Bitcoin in two currencies).

As we published our recommendation to invest in commodities, we got a remark that we should not neglect the contango effect and rollover costs. So we analyzed them and came to a conclusion that although the costs of futures rolling (and ETF fees) are not negligible, they are also not so important, compared to the recent movements of commodity prices.
There were ten futures for the nearest months
Roll over, roll over.
And the January futures was to expire

I show by the example of my portfolio "somewhat better than DUCKS" that CAPM alpha is a very non-robust measure of performance as well as that linear regression on an index should be considered very critically.
Recently, one of my facebook contacts has meant that my portfolio "Somewhat better than DUCKS" repeats the DAX with a beta but without alpha. He even did not make an effort to calculate the linear regression before making this statement. However, even if he did, the results would not be comprehensive.

Currently the stocks are expensive and the commodities are cheap (though not all of them). We conduct a lite analysis of investment opportunities and construct a mid-term commodity portfolio for a retail investor with €10000+ capital.

Even if you are not a Forex trader, it is often necessarily to get currency exchange rates, e.g. if you trade [the options on] foreign stocks. Fixer.io provides daily FX-rates from European Central Bank for 31 currencies via JSON API. We present a script to get data in R.

On 17.04.2017 Yahoo.Finance changed its API, so ichart.finance.yahoo.com is (temporarily?!) unavailable. In particular it means that many R-scripts that rely on quantmod/getSymbols() will not function anymore. We discuss the ways to circumvent the API change of Yahoo.Finance and alternatives to it, esp. Alpha Vantage.

Some of QuantLib functionality is ported to R in RQuantLib. In particular the pricing of Barrier options. Unfortunately, only European. But we need American in order to price and simulate future scenarios for the so-called KO-Zertifikate (Knock-Out Warrants), which are quite popular among German retail traders. We show how to quickly adopt the code from QuantLib testsuite, compile it under Linux and integrate with R and web.
