As of Jun 20, the robintrack data comes in a total of 8,467 csv files, each file corresponds to one stock.
Most of the time series started in May 2018, so they have a little over two years of history. Below shows the distribution of the lengths of the time series.
This is how I interpret this graph, called a histogram by the statistics folks. The peak location tells you majority of the files have length of roughly 18000, i.e. each file has that many rows. There are many files, or stocks, with fewer than 18000. For example, judging by the size of the bars, there are roughly a thousand files with length between 5000 and 10000 rows. And also there are a few outliers with far more data points than others, marked on the far right:
EBR.csv GEF.csv HEI.csv HVT.csv LEN.csv MKC.csv PBR.csv STZ.csv WSO.csv
They are a bit unusual and worth further investigation.
Most of the data are spaced by one hour, i.e. robintrack takes a snapshot of the popularity data from Robinhood every 60 minutes. However, it seems to vary from ticker to ticker. Below shows the distribution of percent of 1-hour intervals.
Some stocks have attracted little interest from the Robinhood community. There is a total of 330 tickers with close to zero user holding over the two year period. Below is a random sample of 10 of them.
"DWMF" "ELON" "PBSM" "QXMI" "VIIZ" "OQAL" "VXX" "INPX" "REIS" "XMHQ"
Here I show the stocks with some abrupt changes in the user holdings. There are 5 of them.
"ACB" "GNUS" "IGC" "INPX" "NKLA" "USO"
The script for the above exercises is data_exploration.R which needs the functions in Fun.R under utils.
