NDX: vGRE* Week 19-Jul-2021

NDX: 1-Jan-21 to 16-Jul-21.

For the week of 12-Jul-2021 to 16-Jul-2021, NDX was up for the first 2 days followed by correcting for the last 3. There was no spike in vGRE* but a gradual reduction over the last 3 days, indicating price stability and yet with a potential upside.

NDX-vGRE* 1-Jan-21 to 16-Jul-21.

The first derivative of vGRE* or the Continuous Return (CR) statistic is also reported for 2021 YTD (16-Jul-2021) to serve as a check for the stationarity of the vGRE* statistic. vGRE*-CR should be a stationary or stochastic process with constant variance and a change of variance indicates deviation from the normal and deserves attention for the specific period.

NDX-vGRE*-Sig from 14-Jun-2021 to 16-Jul-2021.

For the week of 12-Jul-2021 to 16-Jul-2021, there is no breach for vGRE*-CR, hence there is no clear signal for a change in price direction (based on historical data of 2021 YTD, a breach of the CR-statistic range of -0.5 to 0.5 signals a change in price 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. To use it, refer to every trading week which reports 5 signals for Monday to Friday (if there are no public holidays). For eg. 4 buys and 1 sell would indicate an overall buy/hold signal. Again, this is not definitive and is also used as a check with common indicators.

For the week of 12-Jul-2021 to 16-Jul-2021, it starts with 1 sell followed by 4 buys, which is an overall buy/hold signal.
