Market again overbought on overbullish sentiment

The global economy is clearly on the downswing, with the US likely having entered a recession this summer (watch for revisions in GDP and employment data in the coming months). However, as in Sept-Oct 2007, the equity market has bounced from a brief oversold interlude to a new high.

Here is the NAAIM survey. This is a relatively new dataset, but it has proved high-correlated with proven sentiment indicators like DSI and Rydex fund activity). The survey is updated each Thursday with data from Wednesday.

NAAIM Sentiment Survey, 19 Sept 2012

Sentiment has been elevated for a month, which is sufficient for a significant decline, though the likelihood of a setback and the expected magnitude thereof grows with each week that it remains elevated. This, coupled with sideways price action for few weeks (we don’t have this yet) and a declining trend in daily RSI (possibly developing) would virtually lock in the case for an intermediate-term top.

EDIT: To clarify, this is not a screaming short-term sell yet, since the market has had a habit of creaping slightly higher over a few weeks from conditions like this. However, things can reverse at any time, and it is highly likely that any further gains will be quickly erased once the turn comes.

The macro picture of deteriorating economic data bolsters the case that a bull market top is near, so if this is an intermediate-term top it could prove to be the final top prior to a bear market. This cyclical bull is now 3.5 years old. This is long in comparison to the cyclical bulls of the 1910s and 1970s secular bear markets (18-36 months was typical), but short in comparison to the last cyclical bull (spring 2003 – fall 2007, 4.5 years).
