Most of the indicators I use are well known, but I also use a lesser known method to assess the state of market. Other than TrimTabs I don't know many who look at the supply and demand equation for stocks based on what corporations are doing. Corporations could buy stock via repurchases and cash M&A or they can sell stock via IPOs, secondaries or option exercises. When the former is greater than the latter corporations are a source of demand for stocks and vice versa.
The supply and demand equation for equities continues to be a feather in the bulls' caps. I have mentioned numerous times the recent record setting amount of share repurchases and the decent level of cash M&A. Generally, when we see a 25% runup in the market the bankers start rolling out all kinds of secondaries and IPOs. However, given the favorable environment the secondary and IPO calendar has been pretty bare. Insiders have been selling at a brisk pace but probably not brisk enough to make up for all the repurchases and cash M&A.
Tracking the supply and demand for stocks from corporations was a big reason I was confident in backing up the truck late this Summer and Fall when everything looked bleak. This indicator continues to look beneficial to the bulls and in my opinion is a large reason the market has been able to rally so strongly. This does not preclude a correction as the market is stretched but as long as this indicator stays as favorable as it is unlikely we will see a bigger decline, barring a systemic event.
