The Historical Implications of a NASDAQ Breadth Thrust

Key points:

• A "Breadth Thrust" detects market momentum, and typically involves a large number of stocks advancing over a given period relative to the number of stocks declining over the same period
• Two well-known breadth thrust indicators are the Zweig Breadth Thrust and Deemer Breakaway Momentum
• Another such measure that fewer investors are aware of is something I refer to as NASDAQ Breadth Thrust; It recently fired a new signal

A NASDAQ Breadth Thrust Defined

I define a NASDAQ Breadth Thrust (heretofore NBT) as follows:

A = Daily NASDAQ Advances

B = Daily NASDAQ Declines

C = 10-day total of A

D = 10-day total of B

E = ((C/ (C + D)) * 100)

Variable E is simply the percentage of total advances in the last 10 trading days divided by the total of advances and declines.

A new NBT occurs when Variable E closes a day at 62% or higher. A new NBT occurred on April 14^th, 2026. Does it matter?

To address the potential significance, let's consider only the first NBT in any 12 months.
