interesting 52 week range stat

I was recently listening to an episode of the podcast, We Study Billionaires, and heard a stat that sounded amazing. The claim was that a typical stock price average 52 week range fluctuated between 50% and 60%. Some years it may be less, some years, much more (~120%)

What is the most straight forward approach to testing this hypothesis for a given universe over the last X years?

Thanks

Could you perhaps rephrase the question? It seems that you’re asking whether the 52-week range fluctuates between 50% and 60% from one year to another, but maybe that’s incorrect. The 52-week range is simply PriceH - PriceL. You could use FHist to compare that difference from one year to another. Or perhaps you’re wondering if the 52-week range is between 50% and 60% of the high, in which case you could see how many stocks have PriceH > 2PriceL and PriceH < 2.5PriceL.
