NYSE: First Major Accumulation Day In 14 Months

 | Dec 18, 2014 12:29AM ET

The markets hit a large number of extremes at the end of last week (post ). These, together with positive statements from the Fed yesterday, created a major accumulation day (MAD). These are days when up volume on the NYSE is at least 9 times larger than down volume.

That is telling you that investors overwhelmingly see equities as attractive or oversold at current prices. It's a bullish sign and normally (but not always) initiates a move higher in price.

As an aside, 'tick' on the NYSE was also strongly positive today. We look especially for a cluster of ticks over 1000 after a strong period of selling. This means that many stocks are moving up on the ask, not the bid. The highest tick yesterday was 1350, one of the 5 highest of 2014. Overall, the profile of tick is consistent with a MAD.

Yesterday's MAD was 17:1. It was the first MAD since the October 2013 low in the SPX. In the past two years, the only other MAD was January 2, 2013. Both of these initiated long moves higher in the SPX.
