The YXI Signal (May 23, 2025)
Systematic Signals for Smarter Trades In SPY, QQQ, BTC, TLT, AAPL, AMZN, GOOGL, META, MSFT, NVDA, TSLA, PLTR
Hi YXI friends,
Every Friday, we review how the systematic signals have done since launch. Living and breathing the systematic signals in real time is very different to looking at pretty backtesting charts.
There will be plenty of days or even streaks of days when the models are wrong. Moreover, investor psychology matters arguably even more when following the machine. The human instinct is always to look for “reasons” and “narratives” to satisfy their decision making. But here, to a degree, we are “blindly” trusting something that appears smarter without it giving precise explanations to how they reach the conclusions.
Even the late Jim Simons of Renaissance Technologies had days where he felt really stuck with the algo’s poor performance he was unsure whether to pull the plug or to plough through. And often, as soon as he did actually pull the plug and dialled back risk, the market bounced back strongly.

How The Model Works
We employ individual proprietary machine learning models for each name we cover to outperform the Buy-and-Hold strategy. The model examines the various macro drivers and asset specific factors against an 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.
