Maximum Drawdown is a common risk metric used in quantitative finance to assess the largest negative return that has been experienced. If you would like to see these ratios applied to a more realistic backtest you can take a look at this crypto-algo trading example As with the Sharpe and Sortino, higher values are preferable. It appears that Microsoft performs the best according to this ratio. Try this: def MDD (returns): cumrets (1 + returns).cumprod () - 1 nav ( (1 + cumrets) 100).fillna (100) hwm nav.

The function below assumes that returns is either a pandas series or a column of a pandas dataframe. The Sharpe ratio also provides a useful metric to compare investments. 2 Answers Sorted by: 5 You are missing a few things. This allows us to adjust the returns on an investment by the amount of risk that was taken in order to achieve it.

For every $1 you invested in Apple in 2013 you would now have approximately $7 and so-forth. The plot shows the growth of $1 invested on 1st Jan 2013 until 10th Oct 2020. df = stocks.pct_change().dropna()ĭf = df.mean(axis=1) # 20% apple. Plot the normalized stock prices for comparison.

Port: Equally weighted portfolio of the securities above.

Since the statistics in question are usually calculated on a portfolio, we will add an equal weighted portfolio to the analysis also. In order to provide examples on real data we will use the following stocks to illustrate the concepts shown. A simpler way of seeing the formula in action is to reduce the range to say only 4 or 5 cells and jump into evaluate formula.In this article we will calculate the a number of well know statistics related to risk and reward in equities. Once you have the calculated array of 8, a MIN/MAX function will give you desired results. The N() simply converts this to 1s or 0s depending upon TRUE or FALSE. To create this matrix, the TRANSPOSE(ROW(A2:A9))<=ROW(A2:A9)) comes into picture. 5 values summed in the 5th set, 6 in the 6th and so on. The increasing number of 1s in each set means that the next value in A2:A9 is added to the respective SUMPRODUCT calculation, thereby giving you a cumulative total of the 'x' number of entries depending upon which set you are looking at i.e. Each of these eight sets will now get multiplied by the respective values in A2:A9 and summed, essentially a SUMPRODUCT(), thereby giving you a result of 8 summed up values. The matrix of 64 (8 sets of 8 each, since range of data is 8 rows) will start with a single 1 and seven 0s, two 1s and six 0s, three 1s and 5 0s, four 1s and four 0s.
