As simple as this:

string s = "Shipments will cost $150USD , which representes a rise of %34 .";
            var matches = Regex.Matches(s, @"(\$|%)\w+");
            for (int i = 0; i < matches.Count; i++)
            {
                Console.WriteLine(matches[i].Value);
            }

If you mean finding all words, you can use that regex.

(?<=\s?)[%$]\w+(?=\s?)

So in Shipments will cost $150USD, which representes a rise of %34. it will find $150USD and %34.

The C# code is:

String subjectString = "Shipments will cost $150USD, which representes a rise of %34.";
var matches = Regex.Matches(subjectString, @"(?<=\s?)[%$]\w+(?=\s?)");

foreach (Match match in matches)
{
    var value = match.Value;
}
