As an aside we disagree from this simplistic analysis because as is well known, the "Household" category, which is pulled from the Fed's quarterly Flow of Funds report, is merely a placeholder plug, designed to balance out all the other member categories. What is less known is that entities such as hedge funds use extensive "off the books" leverage (just ask Citadel and its nearly 9x regulatory leverage) to hold far more equities than their capital allows them. Which means that in reality the US household owns far less stock than is believed.

But even if one takes the Fed's data at face value, what becomes clear is that having owned virtually the entire stock market in 1945, households are now down to nearly their lowest fractional ownership in history, with the rest alloted to mutual, pension and retirement funds.

And it is only going to get worse.

According to a recent analysis by Goldman, in 2014 the US household is on track to withdraw a whopping $430 billion from US corporate stocks. i.e., sell. This will be the biggest net outflow by the Household group, which has constantly withdrawn cash from equities over the past decade, since the last market peak.
