  • Weekly S&P500 ChartStorm - 27 September 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: The stockmarket has undergone a “stealth correction”. The equal-weighted S&P500 is down more than 5% off the peak. Breadth has been beaten down, and traders have been raising cash. Momentum stocks regaining momentum, profit margins punching higher. Valuations r…

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Tech stock ETF flows recently reached record highs. Foreign flows into US stocks are surging (record highs). CEO confidence, ISM PMIs, and freight data are turning up. Margin debt indicators are sounding a clear risk warning signal. Much of the index are heading into a buyback blackout window. Overall , there is a lot of good news on the earnings and economy front as a broader cyclical upturn gets underway. But there are still lingering macro/(geo)political risks and market warning signs that…

  • Weekly S&P500 ChartStorm - 13 September 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Stocks are seeing a bit of pre-Fed jitters. Breadth has been steadily deteriorating across the board. Correlations, corporate bonds, and volatility suggest caution. Liquidity conditions are set to become a headwind for stocks. Growth has peaked vs value, semis are stagnating (for now). Overall , there is a distinct bearish hue to the charts this week as technical risk flags wave all around. As noted below though, there is a bullish way for this to resolve, but a few things need to happen… 1…

  • Weekly S&P500 ChartStorm - 6 September 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: The S&P500 has been experiencing some speed wobbles. Seasonally speaking, this comes right about as you’d expect. Credit markets are whispering a couple of concerns (tech, CCC’s). Beware of boom-bust in tech/AI particularly as borrowing blooms. Profit margins h…

  • Weekly S&P500 ChartStorm - 30 August 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Sentiment is still majority consensus bullish. Stock correlations have dropped to record lows. Volatility (VIX) looks low vs seasonals and single-stock metrics. Semis are still stuck in the mud (peaked, and looking weak). Software is looking stronger (software …

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Global corporate earnings estimates are surging. Tech is seeing big insider buying (but also heavy shorting). Energy, Gold, Bitcoin seen major ETF outflows (+are all turning up again). Indian stocks have been punished as an AI-loser within emerging markets. The VIX is bouncing along the bottom of the range, seasonality says it goes up. Overall , the global equities bull market looks alive and well, especially when you consider the surge in earnings expectations underpinning it. US tech stocks…

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: The equal-weighted is turning up vs cap-weighted S&P500. For now this is a good thing, it reflects the bullish broadening theme. Earnings revisions are surging, and this is partly supported by strong macro. Sentiment & allocations are surging thanks to higher …

  • Weekly S&P500 ChartStorm - 9 August 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Global equities are in a bull market (path of least resistance = higher). US equities are in a broad-based upswing. Investors are scrambling into tech stocks at a record pace. Calm macro is keeping the lid on credit spreads. (but) VIX seasonality says stay alert to Q3 surprises. Overall , the global equity bull market rages on, and with supportive-benign macro the path of least resistance is likely higher. That said, VIX seasonality and known tail risks suggest still having a plan and process…

  • Weekly S&P500 ChartStorm - 2 August 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: The S&P500 closed July down -0.1% (but still up +9.4% YTD). Semiconductors have seen a 20%+ correction off the peak. Semiconductors’ seasonality says down, volatility says up. REITs and defensives are sounding a cautionary tone. Resources capex is being crowded out by tech capex. Overall , the carnage that unfolded last week in semiconductors is probably more likely setting up for consolidation and ranging (at best) vs the correction and resurgence like we saw earlier this year, as various…

  • Weekly S&P500 ChartStorm - 26 July 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: Mag-7, the 493, cap + equal-weighted S&P500 have all peaked. Market messiness is coming right on schedule (seasonally speaking). Retail trading behavior is consistent with the hints of regime change. Fed rate hike risk echoes global trends, and may weight further on stocks. The backdrop of expensive valuations and low cash allocations is not ideal. Overall , there has been a distinct change in tone this past week in markets, the flare-up in geopolitics is making markets wary along with rising…

  • Weekly S&P500 ChartStorm - 19 July 2026

    Welcome to the latest Weekly S&P500 #ChartStorm ! Learnings and conclusions from this week’s charts: The cap-weighted S&P500 is being held back by semis. The equal-weighted is looking good, and breadth is trending up. The unwind in Semis and Korean equities looks bubble-bursty. Margin debt growth and seasonality are waving risk flags. Relative value indicators are also presenting an omen. Overall , it’s a bit of a conflicting picture at the moment. On the one hand “the market of stocks” is looking great; the equal-weighted index is trending up and breadth is improving. On the other hand…
