Yeah, not sure about how they're measuring. By market cap, Shimano is about four and a half times larger. P/E is very close between the two; Giant's PY return is about 77 times better than Shimano's.
They go for anywhere from a couple hundred to 1k+ (like the Stellas) apiece and you typically want 3 - 5 rod/reel setups when going on a fishing trip.
