You may try:
str1 <- c("American Tower Corporation (REIT)Â (AMT)", "Aetna Inc.Â (AET)")
# "AMT" "AET"

Dear R Helpers,
My regex skills are beginner to intermediate and banging around the web
has not resulted in a solution to the problem below so I hope that one of
you who has mad skills can help me out.
I want to extract the stock ticker--AMT-- out of the string
American Tower Corporation (REIT)Â (AMT)
The presence of the other parenthetical text (REIT) makes this difficult.
Please note that the string may or may not have a interfering set of
characters such as the (REIT) so the solution needs to be generalizable to
the last set of characters that are contained in parentheses in the larger
string. So an example of a string without the interfering (REIT) would be
Aetna Inc.Â (AET)
Your assistance would be very much appreciated.
