Cramer always notes superlatives in any stock. What does he think of this play now?
Sometimes a 52-week high can be a sign of the top and other times it can suggest a break out lies ahead.
It's the latter scenario that Jim Cramer thinks is more likely as Seattle Genetics touched not only a 52-week high but an all time high on Monday.
"I still think it has more room to run," said the Mad Money host.
Cramer has been a fan of the space broadly and this company in particular for quite some time. In December 2012, the Mad Money host suggested putting Seattle Genetics on your radar as a potential buy. Had you pulled the trigger at that time, you'd already have an 85% gain.
But even if you missed those gains – the Mad Money host still sees opportunity.
He continues to believe powerful catalysts -- such as the ground breaking ways in which the company's products help patients battle cancer -- can drive shares even higher.
