The YXI Signal (June 12, 2025)
Systematic Signals for Smarter Trades In SPY, QQQ, BTC, TLT, AAPL, AMZN, GOOGL, META, MSFT, NVDA, TSLA, PLTR
Hi YXI friends,
SPY and QQQ both opened higher on Wednesday, but the intraday rally got smacked by the bears in the afternoon.
Whether that opening high was the “local top” remains to be seen. For now, we take one day at a time and play the market in front of us, not risk off just yet.
We currently offer SPY, QQQ, BTC, TLT, AAPL, AMZN, GOOGL, META, MSFT, NVDA, TSLA, and PLTR daily systematic signals through machine learning in this service. We combine these signals with our other methodologies in the full daily macro note for in-depth analysis.
I plan to keep TSLA and PLTR free for everyone, everyday. Please share the newsletter with friends and colleagues who may find it helpful for reference.
Premium subscribers can enjoy daily access to SPY, QQQ, BTC, TLT, AAPL, AMZN, GOOGL, META, MSFT, and NVDA signals. If you haven’t already, subscribe now to lock in the current price forever.
How The Model Works
We employ proprietary machine learning models for each asset to maximise the Sharpe ratio and minimise the drawdowns when trading the name. The model achieves this by examining a number of macro drivers and asset specific factors against the asset’s historical price movements. It is a long-only strategy without leverage.
In interpreting the signal, 1 occurs when the model prefers being “position on” and 0 when preferring “cash”. There is no “minimum” holding period when the signal shows 1. The model strategy simply holds the asset until the signal turns to 0. This could be after 1 day, 1 week, or longer.
The unique strength of our offering is the combination of the independent cross-asset signals everyday, to clearly illustrate the market sentiment.
The model will NOT be 100% correct in its market prediction everyday (no model can be - please run away if someone claims this). Each model is being improved over time, so the below success rates and back-test results are subject to change. Currently, the model returns are calculated using the daily closes versus the previous day. The model outputs are not financial advice and there is no guarantee of future performance.
