Trading With the NYSE TICK
Trading With the NYSE TICK - Part Two
Trading With the NYSE TICK - Part Three
Since July, 2003 (N = 774 trading days), I found 63 occasions in which the S&P 500 Index (SPY) was up by more than 1% on the day. Four days later, SPY was up on average by .07% (35 up, 28 down). That represents no bullish edge whatsoever relative to the average four-day SPY gain of .14% (432 up, 342 down) for the entire sample.
Now, however, let's factor the NYSE TICK into the mix. When SPY has been up by more than 1% *and* the NYSE TICK has been strong (N = 31), the next four days in SPY average a gain of .39% (22 up, 9 down). When SPY has been up by more than 1% and the TICK has been weak (N = 32), the next four days in SPY have averaged a loss of -.24% (13 up, 19 down). Clearly, the TICK makes a difference: a single day's TICK reading has bullish or bearish implications four days out.
How about when the S&P 500 (SPY) is weak on the day? We had 67 occasions in which SPY has been down by more than 1% in a single day since July, 2003. When the SPY was weak and the NYSE TICK was relatively strong (N = 34), the next four days in SPY average a gain of .39% (21 up, 13 down). When SPY was weak *and* the TICK was weak (N = 33), the next four days in SPY averaged a gain of only .03% (16 up, 17 down). Once again, we see that a single day's TICK reading exerts an influence several days out.
Now let's look at the TICK over multiple days. When the adjusted NYSE TICK averages more than +500 over a four-day period (N = 36), the *next* four days in SPY average a gain of .39% (23 up, 13 down). That is much stronger than the average four-day gain of .14%, as noted above. When the TICK averages less than -500 over a four-day period (N = 34), the next four days in SPY average a gain of .48% (23 up, 11 down)--again much stronger than average.
