Institutional ownership refers to the percentage of a company’s shares that is owned by large institutional investors such as mutual funds, hedge funds, pension funds, etc…
Most finance sites that provide stock quotes also track this metric. Based on what I can see, it looks like Google Finance may have a technical issue or two with the data they are showing for this metric.
I’ll provide two examples. The first is VeriFone. According to the Google Finance quote, this company has an institutional ownership of 103%. No need to double check with other finance sites. Already we can see that this is technically impossible (as the highest amount of ownership is by definition 100%).
The second example is Google. According to the Google Finance quote, this company has an institutional ownership of 66%. Based on my limited knowledge of the stock market, this seemed way too low of a number. So after double-checking with a couple of other sites (Yahoo Finance & Etrade), I’m assured to know this number is actually closer to 83%.
Most likely the Google Finance Institutionally Owned metric is simply outputting a number it gets from a stock service data feed. It could very well be the case that this feed is what is feeding the site the corrupted information. But either way, this is something that should be fixed.
