Us Market Bubble Detector

This is a surprisingly rigorous framework for evaluating US market bubble risk through quantitative metrics like Put/Call ratios, VIX levels, margin debt, and IPO activity. It forces you to collect actual data before scoring anything, then adds strict qualitative adjustments with hard caps to prevent confirmation bias. The v2.1 revision cuts down on wiggle room with explicit thresholds and evidence requirements, which is honestly refreshing given how much hand-waving happens in market analysis. Use it when someone asks if we're in a bubble or when you need to make a disciplined profit-taking decision. The phase-based scoring system (0-15 points) maps to specific risk budgets, so you get actionable guidance instead of vague concerns.
