Carnival Corp. (CCL) - Get Report shares were falling Thursday after posting mixed fourth-quarter earnings and weak guidance.

Despite getting its cash pile up to $982 million from $395 million at the end of November 2017, Carnival's stock has fallen more than 22% year to date. 

Since Oct. 9, when the U.S. stock market started getting hit with a nasty selling spree, Carnival shares have fallen about 15%. They were at $61 a share on Oct.  9.
