June traffic trends at Six Flags seem to have slowed a bit versus May, but still show an improvement from last year, according to UBS in a research note. Using in house analytics, UBS says the first three weeks of June were up 32% year-over-year vs. April and May's 42% rise on average. Six Flags reported year-to-date attendance through the end of April up 4% on a same-park basis. The analysts say investors expect 2Q attendance growth to be in the 3% to 3.5% range, which is set to benefit from easier year-over-year comparisons. "Outside of top-line trends, investors are also focused on cost management for FUN regardless of where demand shakes out," they say, given that margins were under pressure last year.(connor.hart@wsj.com)
