QFRG and DSLab – monthly meetings

QFRG&DSLab

The joint project of Quantitative Finance Research Group and Data Science Lab open seminars has been started in 2019/2020 academic year and was thought of as the place for discussion of the newest research ideas coming from the latest scientific articles. We focus on research from the area of data science, quantitative finance, financial econometrics, machine learning, and risk management.

COVID-19 w Polsce – gdzie jesteśmy i dokąd zmierzamy?

coronavirus_picture

W naszych najnowszych analizach tym razem nie ma żadnego machine learning, ani bardziej zaawansowanych technik obliczeniowych. Jest to jednak działanie w pełni zamierzone, ponieważ czasem wystarczą proste operacje arytmetyczne, aby na gruncie dostępnych danych pokazać kilka istotnych obserwacji i wniosków, które powinny być wyraźnie zrozumiane.

5. 2020-12-18

W kolejnym wpisie ponownie jedynie aktualizujemy poprzednie dane, a jego tytuł tym razem brzmi jeszcze mniej optymistycznie: “Prawie 33 tys. nadwyżkowych zgonów w ciągu ostatnich 13 tygodni! Czy oficjalne statystyki odniosą się w końcu do pytania: na co umierają Polacy?”

W dalszym ciągu analizujemy dane GUS oraz KPRM RSC dotyczące liczby tygodniowych zgonów (okres od 38. do 50. tygodnia, czyli do 2020-12-13).

W tym okresie liczba zgonów powyżej średniej za okres 2015-2019 wyniosła 53.6 tys., zaś śmiertelność z powodu COVID-19 wg. oficjalnych statystyk była w tym samym okresie na poziomie 20.8 tys. osób.

Należy kolejny raz zapytać wprost: czy te obserwacje są efektem zaniedbania profilaktyki większości śmiercionośnych chorób w trakcie epidemii COVID-19, i co mogliśmy lub możemy zrobić w najbliższym czasie aby zahamować tę falę nadwyżkowej śmiertelności?

Nasze obliczenia oraz źródła dostępne są w tym arkuszu: https://docs.google.com/spreadsheets/d/1Q0rhf8ZTxK8Ii2Al0SrTPQ9Xtqb5glvwnf0LQtmIw8E/edit?usp=sharing

Źródła:

4. 2020-11-28

Nasz nastepny wpis będzie aktualizacją poprzednich danych dla dłuższgo okresu, a jego tytuł brzmi: “Ponad 24 tys. nadwyżkowych zgonów w ciągu ostatnich 9 tygodni! Kiedy oficjalne statystyki odniosą się do pytania: na co umierają Polacy?”

W dalszym ciągu analizujemy dane GUS oraz KPRM RSC dotyczące liczby tygodniowych zgonów (okres od 38. do 46. tygodnia, czyli do 2020-11-15).

W tym okresie liczba zgonów powyżej średniej za okres 2015-2019 wyniosła 32,5 tys., zaś śmiertelność z powodu COVID-19 wg. oficjalnych statystyk była w tym samym okresie na poziomie 8.3 tys. osób.

Należy kolejny raz zapytać wprost: czy te obserwacje są efektem zaniedbania profilaktyki większości śmiercionośnych chorób w trakcie epidemii COVID-19?

Nasze obliczenia oraz źródła dostępne są w tym arkuszu: https://docs.google.com/spreadsheets/d/1Q0rhf8ZTxK8Ii2Al0SrTPQ9Xtqb5glvwnf0LQtmIw8E/edit?usp=sharing

Źródła:

3. 2020-11-17

Kolejny bardzo krótki wpis ograniczający się do trzech wykresów i kilku zdań ma następujący tytuł: “Na co umarło 11,5 tys. Polaków w październiku 2020?”

Przyjrzeliśmy się w nim danym dotyczącym liczby tygodniowych zgonów opublikowanym wczoraj przez GUS (okres od 41. do 44. tygodnia 2020).

W tym okresie liczba zgonów powyżej średniej za okres 2015-2019 wyniosła 14,5 tys., zaś śmiertelność z powodu COVID-19 według oficjalnych statystyk była w tym samym okresie na poziomie 3,1 tys. osób.

Czyżbyśmy właśnie zaczęli obserwować tragiczne skutki zapaści służby zdrowia w Polsce?

Nasze obliczenia oraz źródła dostępne są w tym arkuszu: https://lnkd.in/gRjTE-3

Do ewentualnych komentarzy zachęcamy na linkedin: https://www.linkedin.com/posts/robert-%C5%9Blepaczuk-phd-2053036_covid-covid19insights-covid19impact-activity-6734435907451129856-52fR

2. 2020-11-16

Zachęceni licznymi komentarzami do naszej pierwszej analizy,  postanowiliśmy ją zaktualizować oraz dodać kilka nowych wątków, skupiając się na standardowych i bardziej kontrowersyjnych zagadnieniach związanych z walką z epidemią COVID-19 w Polsce.

Najnowsza wersja analizy pt.: COVID-19  w Polsce – gdzie jesteśmy i dokąd zmierzamy? – II_raport_2020-11-15, znajduje się tutaj

W najnowszym raporcie poza aktualizacją danych i dokładniejszym podkreśleniem podstawowych obserwacji, wniosków i pytań, dodatkowo uwzględniliśmy:

  • porównanie liczby przypadków aktywnych (=potwierdzone przypadki pomniejszone o przypadki wyleczone),
  • porównanie dziennej śmiertelności podstawowych przyczyn zgonów z COVID-19 w dwóch wersjach,
  • analizę przypadków śmiertelności z powodu COVID-19 z chorobami współistniejącymi w odniesieniu do całkowitej liczby przypadków śmiertelnych z powodu COVID-19,
  • odniesienie do zmian definicji przypadku COVID-19 wprowadzonej przez Ministerstwo Zdrowia na początku listopada,
  • analizę liczby testów oraz współczynnika wykrywalności ((=potwierdzone przypadki / liczba testów)

1. 2020-11-06

Poniżej przedstawiamy krótką analizę pt.: COVID-19 w Polsce – gdzie jesteśmy i dokąd zmierzamy?, opracowaną przez QFRG WNE UW, poprzez którą chcieliśmy zwrócić uwagę na kilka istotnych faktów związanych z epidemią COVID-19 w Polsce oraz jej konsekwencjami.

Życzymy przyjemnej lektury

Coronavirus and capital markets – updated version – 2020-03-31

figure27_20200330

Increasing panic in societies helps to control them and influence their decisions but at the same time it limits their rational behaviors and stop them from the most appropriate actions at the correct time, so … should we present well-processed data, e.g. properly showing the dynamics of the development of the epidemic in each country or should we focus only on absolute numbers which will naturally grow to the very end of the epidemic? – the question is of course rhetorical.

… despite the fact that the level of panic recently observed on financial markets is not fully justified, at the same time the prolonged unprecedented governmental activities related to closing borders, isolating economies, the inability to conduct business in a normal form and, as a consequence, a complete break in the supply chain can have very negative and unpredictable economic effects. What is worse, the subsequent consequences of these activities, e.g. related to the bankruptcy of even entire sectors of the economy, may have in practice much more severe consequences for the societies of individual countries through significant and permanent destabilization of entire economies, and then the current exaggerated reaction of exchanges, unfortunately post factum, will show fully adequate!

Koronawirus COVID-19 a rynki kapitałowe

Figure26

Indeks S&P500 spadł w okresie ostatnich 4 tygodni do wartości poniżej 2280.52 notując jedne z największych krótkoterminowych spadków (około -32.8%), w okresie ostatnich kilkudziesięciu lat. Wydarzenia ostatnich 4 tygodni skłaniają do przeanalizowania przyczyn tak dużej paniki na rynkach finansowych z większą uwagą. Skłoniło to nas do poświęcenia temu tematowi trochę czasu co zaowocowało następującym opracowaniem.

Skupimy się na następujących aspektach:
• opisie reakcji rynków kapitałowych na rozwój epidemii na przykładzie indeksu S&P500 oraz indeksu zmienności VIX,
• rozwoju epidemii na świecie w krajach z największą liczbą przypadków koronawirusa,
• ewolucji wskaźnika śmiertelności na podstawie dwóch różnych definicji oraz odpowiedzi na pytanie co z tego wynika,
• potencjalnym wpływie obecnej pandemii na gospodarki krajów oraz zachowanie giełd w przyszłości.

oraz na odniesieniu do poniższych pytań:
… czy sytuacja jest aż tak tragiczna lub inaczej to ujmując, czy mamy podstawy przypuszczać, że za chwilę będziemy w tak katastroficznej sytuacji jak sugeruje zachowanie rynków finansowych?
… czy rynki finansowe dyskontują obecnie scenariusz adekwatny do danych, które obecnie posiadamy, czy raczej skrajnie pesymistyczny, zakładający bardzo gwałtowny rozwój epidemii w kolejnych tygodniach i totalną destabilizację rynków finansowych i gospodarek poszczególnych krajów?
… czy zatem rynki finansowe nie uwzględniają jedynie skrajnie negatywnego scenariusza rozwoju sytuacji?

Życzymy przyjemnej lektury!

[5:15 pm – 6:15 pm] Diversification with cryptocurrencies? OMG, really? by dr Paweł Sakowski and Przemysław Ryś,

Abstract:
Our interactive cloud-deployed Shiny application implements Markowitz (1952) model for equity and crypto markets. We can analyse not only equity lines and performance measures for our strategies and benchmark portfolios, but also perform interactive sensitivity analysis with respect to the length of historical window, the frequency of portfolio rebalancing and the degree of financial leverage. The app serves to illustrate the potential of portfolio risk diversification offered by crypto markets. Presentation of our application will be accompanied with a gentle introduction to Modern Portfolio Analysis – it’s not a rocket science, so everyone is invited!

CMI returns are calculated based on the formula which attaches the same weight to every return.Rebalancing is done every day.

Description of data

Our data covers the period between 2017-11-01 and 2019-04-08. The starting point is defined as the date when minimum 2 time series are available for calculations purposes. Then each new time series is added when data are available.All prices are converted to USD, e.g. from GBP or CAD. Data sources:
