Moving average of Market Cap does not always return the correct values.
I created a custom field to take a 26 week moving average Market Cap. When looking at UniSearch results I found that for many stocks the values returned made no sense to me.
As an example, NVDA is part of Semiconductor Manufacturing. The range of market cap on the industry over the last 26 week is between $9B-$11B but the custom field reports $16B in Unisearch.
