@emcor I would suggest downloading the Stock's daily Prices & then downloading Shares Outstanding or average shares outstanding. Then find the product of the two to arrive at market caps. I don't know how reliable quandl's data is or if they have shares outstanding data, but if they do this can probably be done using R code since you will be downloading ...

Having locked markets is bad in the sense it freezes the price formation process. Ideally we would like to have a price on as much instruments as possible so that we know their value. it prevent investors to buy (or sell) it and thus adds frictions, transaction costs, etc. We would like to enable investors to buy or sell when they need/want, to let the ...

R is very useful for downloading data from Yahoo/Google . Here is an example for downloading from Google Finance : library(quantmod) getSymbols("DRRX;AAPL;AMZN", from="2014-01-01", to="2014-11-20", src='google') Just adjust the from and to dates as needed.

So im always storing at least 15 digits for DF, and yields up to 7-8 as rhaskett said. For equities, i guess it's pretty much the same as for yields, or even less. Nevertheless i store any return, price or ratio with a 7-8 ...

As background, Floating point precision is a way of storing numbers such that the precision is relative to the largest digit. For instance, the number $0.00123$ stored in fixed precision needs 6 digits of precision (3 zeros and the 3 non-zero numbers).

Errors in some data can cause the calculation to go awry. For EPD, I have reported that they believe the stock had a 2:1 split on August 21, 2014 and on August 22, 2014. Only one of these splits occurred, so all the split adjusted data is off by a factor of 2 before the split that did not happen. I reported this error in August, but in November I noticed ...
