Krinsky warns SPY overbought with RSI above 70, weak breadth, semis/AI losses, and 5% yields. He sees small-cap value and defensives as positives. Next catalyst: FOMC.
Alpha Score of 39 reflects weak overall profile with strong momentum, poor value, moderate sentiment. Based on 3 of 4 signals — score is capped at 90 until remaining data ingests.
BTIG technical strategist Jonathan Krinsky issued a rare outright warning on the SPY this week. The S&P 500 ETF is overbought on multiple signals: a stretched RSI, deteriorating breadth, mounting losses in semiconductors and AI names, and a yield backdrop that has historically capped equity upside. Krinsky's call is not a blanket sell signal. He identified two areas that still look constructive. The list of red flags is long enough that he sees a heightened probability of a pullback.
Krinsky's first warning is the simplest. The Relative Strength Index on SPY has pushed above 70, the classic overbought threshold. A single RSI reading above 70 does not guarantee a reversal. During a strong uptrend, the index can stay extended for weeks. Krinsky is combining it with breadth data that shows narrowing participation. Fewer stocks are driving the recent rally. Laggards in semiconductors and AI – the leadership group of 2024 and early 2025 – are starting to lose momentum. When the leaders stumble and breadth weakens, the market is more vulnerable to a corrective move.
The second pressure point is the 10-year Treasury yield flirting with 5%. A 5% yield changes the calculus for equity investors. It raises the discount rate on future cash flows, which hits growth and tech stocks hardest. It also gives fixed income a real yield advantage relative to the equity risk premium. Krinsky is not calling for a repeat of the 2023 yield spike. The proximity to 5% creates a ceiling on how high-multiple names can trade. The combination of overbought technicals and rising real rates is the kind of cross-asset tension that frequently precedes at least a 3-5% drawdown in broad indices.
Krinsky does not leave readers with only warning signs. He names two positives: small-cap value stocks and defensive sectors like utilities and healthcare. Small-cap value, as measured by the Russell 2000 Value Index, has shown relative strength that actually started to show relative strength. For many traders, that sounds counterintuitive. If the market is overbought, why buy more risky small caps? The answer is rotation. If Krinsky is right, money is flowing out of overextended large-cap growth (especially big tech) into laggards that still have room to run on a valuation basis. Defensives work in this scenario as hedges against a broader pullback.
This is a classic technical setup where the simple read is misleading. The naive interpretation: "RSI above 70 means sell." The better market read: wait for confirmation of weakness before de-risking. A first touch of an overbought reading is often faded. What matters is the second touch or a failure to break higher after the RSI relaxes into neutral. Krinsky is essentially putting traders on watch for that breakdown.
Confirmation would be SPY breaking below its 20-day moving average with volume, or the RSI falling below 60 after an extended stay above-zone print. Invalidation would be the index grinding higher without breadth confirmation, which is actually possible in a momentum-driven market. The safest approach for active managers is to trim positions in names that have rallied 20%+ without earnings revisions, and to rotate into the areas Krinsky highlighted as constructive.
The next catalyst for this story is the FOMC meeting in two weeks and the following CPI print. If yields stay near 5% and breadth continues to soften, Krinsky's warning could become a self-fulfilling correction. If the FOMC signals a willingness to cut rates even with sticky inflation, the 5% yield ceiling could break. SPY would likely resume its uptrend. The setup is fragile, not broken.
AlphaScala's own SPY Alpha Score stands at 39 out of 100, labeled Mixed. That score points the same direction: near-term caution with no clear directional edge. For now, the prudent path is to take Krinsky's checklist seriously and wait for the next confirming data point before making a major portfolio tilt.
