NDX: vGRE* Week 9-Aug-2021
Finamatrix.AI — Analyzing data from the previous week can shed light on the coming week for NDX with genetic-optimization. Based on vGRE* there was a small spike on Tuesday followed by a gradual dip over the week, suggesting a potential downside. For the week of 2-Aug-2021 to 6-Aug-2021, there is no clear breach for vGRE*-CR but a near breach on Tuesday warns a change in price direction; 3 buy/hold signals against 2 sell/short for the week suggests an overall buy/hold strategy for the coming week albeit with limited upside.
- For the week of 2-Aug-2021 to 6-Aug-2021, NDX ended higher at 15,109.
- The vGRE* spiked on Tuesday (3-Aug-21) followed by a gradual decrease, indicating a potential downside for NDX for next week.
The first derivative of vGRE* or the Continuous Return (CR) statistic is also reported for 2021 YTD (6-Aug-2021) to serve as a check for the stationarity of the vGRE* statistic. vGRE*-CR should be a stochastic process with constant variance and a change of variance indicates deviation from the normal and deserves attention for the specific period.
For the week of 2-Aug-2021 to 6-Aug-2021, there is no breach for vGRE*-CR and stayed within the CR-statistic range of -0.5 to 0.5 although on Tuesday (3-Aug-21) the CR-statistic jumped close to 0.5, suggesting a flat NDX direction.
In addition, the genetic-optimization of the golden-ratio estimator produces a value-added statistic where we name as Signal (Sig). The signal of 1 (buy/hold) and 0 (sell/short) are reported per trading day. For the week of 2-Aug-2021 to 6-Aug-2021, it starts off with a 1 and alternates to 0 and ends on Friday (6-Aug-21) with a 1 sig. 3 buy/hold with 2 sell/short signals suggest an overall buy/hold signal for the week of 9-Aug-2021 with limited upside.
