For the fine print (a.k.a. the lawyer-approved stuff), don’t miss the Disclaimers section—it’s where all the “officially important” bits live!

GDR Model Outlook

Overall Outlook (as of 20 Oct 2025): NEUTRAL. The GDR Model has been pointing to an indecisive market.

Fundamentals Outlook (as of 16 Oct 2025): Fair Value/Rich. The model has adjusted valuations slightly upward following the release of new data. Going forward GDR Model positioning should tactically tilt a little more towards the long side, all else equal. Note that this is just a barometer to help guide longer-term decision-making rather than short-term market timing.

IMPORTANT NOTE: it’s unknown what the impact of tariffs on valuations (or what the ultimate level of the tariffs themselves) will actually be on valuations. Rather than make tariff-related assumptions to adjust the model accordingly, the Fundamentals Outlook will remain fully data-driven as it’s always been. All other portions of the model are entirely unaffected.

Long-Term Outlook (as of 17 Oct 2025): Neutral. Any hope for renewed strength all but vanished at the end of the week of the 6th. Since then, the market has continued to show weakness amidst the frequent back-and-forth in prices.

Short-Term Outlook (as of 20 Oct 2025): Neutral. The market showed strength in the short-term timeframe today, but no upgrade (yet).

Breadth Outlook (as of 20 Oct 2025): Bullish. Even though breadth is upgraded to bullish, this recent back-and-forth still highlights the fact that the market isn’t on solid footing at this point.

Volatility Outlook (as of 20 Oct 2025): Shaky. The volatility outlook is back in positive territory, which should help hold the market together if sustained. There’s a fair chance the drop to negative at the end of last week was just a false alarm.

GDR Model Position

The GDR Model has been essentially flat since around mid September after it picked up on fresh weakness. For as long as the market remains indecisive, the model is likely to remain mostly flat.
