The YXI Signal (May 27, 2025)
Systematic Signals for Smarter Trades In SPY, QQQ, BTC, TLT, AAPL, AMZN, GOOGL, META, MSFT, NVDA, TSLA, PLTR
Hi YXI friends,
“Tariff on, tariff off” strikes again over the long weekend between the US and EU. Having threatened with a 50% tariff on the EU imports on Friday starting on June 1, Trump postponed the tariffs to July 9. The delay occurred after Trump had a “very nice call” with Ursula von der Leyen, the European Commission chief.

As someone who employs both machine-learning and technical analysis in interpreting the market, the unpredictability of Trump’s announcement, especially over the weekend has definitely made my job more difficult. Moreover, the market has now learnt to de-risk into the weekend, which could make Friday’s price action less reliable for signalling. Unfortunately, it has simply become the cost of doing business in this environment.
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.

How The Model Works
We employ proprietary machine learning models for each asset we cover to maximise the Sharpe ratio in 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.
