The traditional Dow Theory, using the Dow Jones Industrial Average and the Dow Jones Transportation Average, generated a buy signal in mid-May, and a new closing-basis high for the Industrials as of Thursday’s (12/11) close confirms the earlier highs on the Transports. This reinforces the primary bull market signal under this version of Dow Theory and provides a bullish backdrop for U.S. equities. The prior bullish confirmation occurred on November 12, when the Transports closed at a new recovery high to confirm the new recovery high in the Industrials.
We flagged the Dow Transports as bullish in this blog on November 25.

Bullish Dow Theory confirmation from the S&P 500 and Russell 2000
A new daily closing basis high for the S&P 500 on 12/11 confirms the recent highs on the Russell 2000 (IWM), reinforcing this non-traditional Dow Theory buy signal from mid May.

A new closing basis high on the NASDAQ Comp needed for further bullish confirmation
The next step: A new daily closing basis high for the NASDAQ Comp, which would confirm the new closing basis highs for the NYSE Comp. This would reconfirm a primary bull market (aka uptrend) based on this non-traditional version of the Dow Theory.
