Summary

Phil Anderson’s Gann #12 update flags a historic breadth divergence (S&P 500 at record high while nearly 10% of constituents hit 52-week lows — an all-time record for that combination), accelerating inflation (CPI +3.8% April YoY, largest in ~3 years; PPI +6.0%, largest since end-2022), and a confirmed breakout in the 30-year Treasury yield above 5% — the latter from a Mexican Pete ascending triangle pattern PSE had been tracking for months. TBT (ProShares UltraShort 20+ Year Treasury, 2× inverse) is added to the Mex Pete model portfolio with a $34 stop. Anderson draws a direct parallel to the late 1990s internet bubble dynamic: narrow AI-stock concentration driving indexes while average stocks deteriorate under rising rates and inflation.
