Hi YXI friends,

Welcome to everyone who joined us this week!

I have put our TSLA and PLTR machine-learning model backtests as proprietary indicators on TrendSpider. This way you could visualise how the ML model interact with uptrends and downturns.

I have also prepared the visualisation for SPY, QQQ, and Bitcoin signals for our Premium subscribers today.

The signal does not try to catch every single bit of every pullback, but avoids the major part of big setbacks, which results in long-term outperformance. There are still drawdowns - it could feel painful still when it happens. But the drawdowns are relatively shallower than if we simply held through the price cycles.

Execution without emotion, even with the textbook answers in front of us, is an extremely difficult achievement. It is easy to get impatient with the daily performance. What may be helpful is to simply zoom out from time to time.

1. TSLA & PLTR

Today’s YXI TSLA Signal: 1 (Position Long)

Today’s YXI PLTR Signal: 1 (Position Long)

(In interpreting the signal, 1 occurs when the model prefers being “position on” and 0 when preferring “cash”. There is no “minimum” period for the strategy to stay on either signals.)

To understand how our systematic signals work and their backtest results, you can find more details in this dedicated page below.
