Some of the most actively traded stocks of 2015 by the end of May include Bank of America, Apple, General Electric, Microsoft and Intel, according to MarketWatch. During the period, all of these stocks had an average daily volume of over 30 million shares traded, with the highest near three times that mark. Other actively traded stocks in that period included Cisco Systems, AT&T, Pfizer, Ford Motor and Facebook.
Approximately 6.5 billion shares are traded daily in U.S. stock markets, reports Market Watch. The largest companies, such as the ones mentioned above, make up the majority of such volume. For example, of the 500 stocks listed in the Standard & Poor's 500, the top 10 trade more in volume than the lowest 250 of the index.
Although larger companies commonly have more liquidity than smaller companies, meaning their stocks are traded much more frequently, in the first two quarters of 2015, there were some large companies, such as Amazon and Google, whose stocks were not as actively traded as other large companies, adds MarketWatch. Part of the reason for this may be the high prices of their stocks. This does not affect the overall value of the company, but it has an effect on its liquidity.
