Subject: doubt with positive lookaround

I do not understand behavior of positive look arounds in Ruby:

chunked_data = "DIVex>##ECHO=b698fd4cc1ea4c7a4b5c4e1d1c402911##"
p $& if chunked_data =~ /(?=DIVex)DI/            # =>  DI

However,

chunked_data = "<DIVex>##ECHO=b698fd4cc1ea4c7a4b5c4e1d1c402911##"
p $& if chunked_data =~ /(?=<DIVex)DI/            # =>  nil


does < gets treated as special character inside (?= ..) ?
