Click Here For This Week’s SEAF Model “Rainbow Charts” Update
Conclusion, Investment Implications, Strategy
For the fourth consecutive week, the SEAF Model has retained offensive Technology (XLK) and Utilities (XLU) as the two top-ranked sectors, the latter which is now also construed by many as an offensive sector due to the energy demands that AI has thrust upon the market. Communication Services (XLC), another offensive sector, is the third-best-ranked sector this week. At the other end of the spectrum, and for the third consecutive week, economically sensitive Energy (XLE) and cyclical Financials (XLF) are the two worst-ranked sectors.

The SEAF Model: Current Signals & Related Performance
Editor’s Note: These are the latest specific trading signals generated by our SEAF Model, which also includes a rules-based money management component. The backtested performance data below is based on trading a predetermined amount of assets with an equal allocation of those assets across the top three Rankings. The model is updated once per week, on the weekend, and any rebalancing takes place on the market opening the following Monday morning. This is the recommended way to invest via the SEAF Model. Contact us for any additional clarification.
- Effective Monday 10/20, there is a new buy/overweight signal in the Communication Services Select Sector SPDR ETF Fund (XLC).
- The SEAF Model exited it’s October 13th long/overweight signal in the Health Care Select Sector SPDR Fund (XLV) on October 17th for a 1.0% outright gain while outperforming the S&P 500 (SPY) by 0.6%.

In the SEAF Model Graphic below, the Ranking column sorts the entire table of 11 sector ETFs according to the sum of rankings in the Trading (weekly), Tactical (monthly), and Strategic (quarterly) categories, from largest inflows to largest outflows. The premise of the model is to invest in the sectors where the money is going and to avoid the sectors where the money is coming out.
The lower the Ranking number, the stronger the trend of asset flows going into that sector. The top two sectors in each category, according to a positive change in inflows, are highlighted in green. The top two sectors in each category, according to a negative change in outflows, are highlighted in red.

The latest data indicate a multi-timeframe trend of asset inflows into the Technology and Utilities sectors. This is where the money is currently going in the sector space.
The latest data also indicate a multi-timeframe trend of asset outflows from the Energy and Financial sectors. This is where the money is coming from.
SEAF Heat Map
The SEAF Heat Map provides additional insight into the flows of the 11 Sector ETFs. Each time frame is independent, meaning the color spectrum for one period does not affect another. For example, the strongest inflow (dark green) for the trading week is separate from the strongest inflow for the tactical month.
The heat map visually represents the spectrum of inflows and outflows, with green indicating inflows and red indicating outflows. The more extreme the flow, the darker the corresponding color—deep green for strong inflows and deep red for strong outflows. Flows closer to yellow indicate minimal percentage change.
This tool serves as an additional layer of information to help investors not only identify where sector flows are moving but also gauge the relative strength of those flows compared to their peers.
SEAF Model Individual Sector Charts (“Rainbow Charts”)
The charts below display the weekly SEAF Model Ranking Scores over the previous 12 months for the strongest and weakest sectors through October 16th. The line in the upper panel displays these weekly scores within the context of being Favored (3-15, green), Neutral (16-24, yellow), or Avoid (25-33, red) and also displays the trend of asset flows as the money moves in and out of these sectors. The lower panel plots the corresponding weekly relative performance chart of that particular sector versus the S&P 500 (SPY).
Utilities (XLU)
Utilities (XLU) is the SEAF Model’s top-ranked sector this week with a Ranking score of 5, up slightly from 6 a week earlier, and has been one of the top two best-ranked sectors for the past four weeks. The green highlights in Chart 1 below show that Utilities regained Favored status on September 23rd (upper panel), and that XLU has coincidentally outperformed the benchmark S&P 500 (SPY) by 8% since then. Year-to-date, according to sectorspdrs.com, XLU is currently the second-best-performing Sector SPDR ETF, rising by 21.0% while outperforming the S&P 500 (SPY) by 7.7%.
Technology: XLK
Offensive Technology (XLK) is the SEAF Model’s second-ranked sector this week with a Ranking score of 12, significantly lower (less bullish) than the previous week’s score of 3 due to extreme weakness in the Trading time period this past week, where XLK scored a 10. Nevertheless, Technology has been one of the top three-ranked sectors for 23 of the past 26 weeks beginning on Apr 24th, and has been the top-ranked sector 18 times during this period. Chart 1 below shows that XLK has outperformed the benchmark S&P 500 (SPY, lower panel) by 6% since returning to Favored status on Sep 9th, after aggressively outperforming between Apr 24th and Aug 19th amid a sustained Favored ranking. Year-to-date (YTD), according to sectorspdrs.com, XLK is the best-performing Sector SPDR ETF, rising by 22.6% while outperforming SPY by 9.3%. This is the direct result of a consistent Favored SEAF Ranking since late April.
Communication Services (XLC)
Economically sensitive Communication Services (XLC) is the SEAF Model’s third-best-ranked sector this week with a Ranking score of 13, at the lower edge of Favored status. XLC edged back into Favored status at the end of last week (Oct 16th) after preivously being Favored between Aug 1st and Oct 2nd while XLC outperformed the benchmark S&P 500 (SPY) by 5%. Year-to-date, according to sectorspdrs.com, XLC is the third-best performing Sector SPDR ETF, rising by 18.7% while outperforming SPY by 5.4%.
