G50 Stock Index

The G50 is my stock market index of the world's biggest companies by market capitalization. I have done this in the past for the top 30 stocks. Here is the list as of 3/18/2016.  (I would do it for 12/31/15 but it is hard to get historical data for market cap).  About half these companies are in the Dow Jones.  I intend on updating this about once per quarter, and replacing the lower tier companies as needed, without retroactively revising the total.  I have removed BP and BHP Billiton from the list because the prices on these have dropped substantially.

Update (4/6/2016):
I intend to have a rule that companies stay on the list unless their value drops below $100 billion.  New companies are added only if their value exceeds $120 billion.  It looks like Total should soon be replaced by another company.  Keep an eye out.
