What This Guide Covers
A stock can have perfect fundamentals and still lose money if you buy it in the wrong regime. Market regime — whether a market is risk-on, risk-off, or transitioning — changes the meaning of every other signal. A P/E of 7x in a risk-on regime is a bargain. The same P/E in a risk-off regime with foreign capital fleeing is a falling knife.
Journely classifies market regimes by analyzing five dimensions: volatility, sentiment, breadth, credit conditions, and foreign flows. This guide explains each dimension using real data from three markets as of February 16, 2026 — the US (risk-off to neutral), Japan (risk-on but overbought), and Vietnam (risk-on). Every number below is from Journely's live data feeds.
Dimension 1: Volatility
Fear Has a Number
Volatility measures how much prices are swinging — and more importantly, how much the market expects them to swing. Implied volatility (VIX, Nikkei vol) reflects hedging demand. When implied vol is much higher than realized vol, it means traders are paying up for protection — they are scared of what might happen, even if nothing has happened yet.
US: VIX at 20.82 (85th percentile) — elevated fear. Implied volatility 20.6% vs realized volatility 12.4%. Traders are paying 66% more for protection than actual price movement justifies. This gap between implied and realized is the fear premium.
Japan: Nikkei volatility at 31.9%, JPY/USD volatility at 8.8%. Equity volatility is 2.4x currency volatility — a normal ratio, but the absolute level (31.9%) is high. Japanese stocks are swinging harder than US stocks despite the US being in "fear" mode.
Vietnam: 4 stocks hitting daily ceiling limits (+7%) and 5 stocks hitting daily floor limits (-7%) simultaneously. Limit hits signal extreme intraday volatility — the market is moving so fast that circuit breakers are activating on both sides.
Implied vs realized — the contrarian signal
When implied volatility (20.6%) is far above realized volatility (12.4%), it means the market is pricing in a move that has not happened yet. Historically, extreme fear premiums are contrarian — the worst of the move may already be priced in. But this only works if other dimensions (credit, flows) confirm that the fear is overdone. Volatility alone does not determine regime.
Dimension 2: Sentiment
What the Crowd Is Feeling
Sentiment indicators measure investor psychology — fear vs greed, put vs call demand, and how different participant types (retail, institutional, foreign) are behaving. Extreme sentiment readings are contrarian: when everyone is fearful, the market is often near a bottom. When everyone is greedy, it is often near a top.
US: Fear & Greed Index at 36.3 (Fear territory). Put/Call ratio at 1.05 — more puts than calls, meaning investors are buying more downside protection than upside exposure. Retail investors are cautious to fearful.
Japan: Foreign investors net buying +¥187B per week, positive for the second consecutive week. Domestic retail also buying (+¥794B net). Both foreign and domestic money flowing in — this is an accumulation pattern where sentiment across participant types agrees.
Vietnam: Foreign net buying +10.3M shares (+1.75%). Smart money is accumulating — but selectively. Heavy buying in banks (KDH +8.0M, HDB +4.3M, EIB +3.6M, STB +2.2M). Heavy selling in tech (FPT -8.8M) and select names (ACB -4.6M, HPG -2.8M). Sentiment is bullish on value, bearish on momentum.
The US sentiment paradox
US sentiment (Fear at 36.3) contradicts US breadth (advance/decline ratio 9.5 — meaning 19 sectors advancing vs only 2 declining). Retail investors are fearful, but most sectors are going up. This is a classic contrarian accumulation pattern — institutions are buying while retail panics. The fear creates the opportunity, not the danger.
Dimension 3: Breadth
How Many Stocks Are Participating
Breadth measures whether a rally (or selloff) is broad-based or narrow. A market where only 5 mega-caps are rising while everything else falls is fragile. A market where 200 stocks advance and 120 decline is healthy. Breadth tells you whether the headline index number is telling the truth about the underlying market.
US: Advance/decline ratio 9.5 (19 sectors advancing vs 2 declining) — extremely strong breadth. But SPY RSI at 40 (oversold). Strong sector breadth with a weak headline index is a sign that the selloff is concentrated in a few large names, not broad-based.
Japan: Advance/decline ratio 0.18 (bearish) — narrow leadership. Nikkei RSI and TOPIX RSI both at 72 (overbought). A few sectors are driving the index higher while most are declining. Leading: Non-Energy Minerals (+11%), Electronic Tech (+11%). Lagging: Technology Services (-18%).
Vietnam: Advance/decline ratio 1.7 — 204 stocks advancing vs 120 declining. 52% of listed stocks are rising. This is broad participation that supports the risk-on classification. Unlike Japan's narrow leadership, Vietnam's rally has wide support.
Breadth exposes Japan's vulnerability
Japan's headline numbers look great: Nikkei at 56,942, +6% monthly, foreign money flowing in. But breadth tells a different story: A/D ratio of 0.18 means only 2 sectors advance for every 10 that decline. The rally is driven by mining (+11%), semis (+11%), and chemicals (+11%) while tech services (-18%) collapses. Narrow leadership with overbought RSI (72) in a market with an inverted yield curve — this is why regime analysis matters more than headline returns.
Dimension 4: Credit Conditions
What the Bond Market Is Saying
Credit conditions reveal stress that equity markets often ignore until it is too late. The yield curve shape (normal, flat, or inverted), credit spreads (investment grade and high yield), and absolute rate levels tell you whether the financial system is healthy or under pressure. An inverted yield curve — where short rates exceed long rates — has preceded every US recession in modern history.
US: 10-year Treasury at 4.09%, 2-year at 3.47%. Yield curve POSITIVE (+64bp) — normal shape, no recession signal. Investment grade spread +78bp, high yield spread +292bp — both contained and not flashing stress. Credit markets are stable despite equity fear.
Japan: JGB curve INVERTED. Short-term rates at 5.75%, long-term at 3.08%. This is a recession warning — the bond market is pricing in that Japan's economy may weaken. Investment grade spread only 5bp (extremely tight), meaning corporate credit is fine. The recession signal is in the government curve, not corporate bonds.
Vietnam: No comparable sovereign credit data available. Regime classification relies more heavily on volatility, sentiment, breadth, and flows for emerging markets.
Japan's inverted curve vs equity rally — which is right?
Japan's equity market is rallying (+6% monthly) while its yield curve is inverted (recession signal). These cannot both be right long-term. Either the bond market is wrong and the economy stays strong, or the equity rally is a late-cycle move that will reverse. Journely flags this conflict rather than ignoring it — because the correct regime classification is "risk-on but overbought with a recession warning," not simply "risk-on."
Dimension 5: Foreign Flows
Follow the Money Across Borders
Foreign capital flows show where global investors are deploying capital. When foreign money enters a market, it signals confidence from outside observers who have the choice to invest anywhere. When it leaves, it signals that those same observers found better opportunities elsewhere. In emerging and international markets, foreign flows often drive the dominant trend.
US: Institutional positioning heavily concentrated in Mag 7 — 10-13 hedge funds in each of NVDA, MSFT, AMZN, META, GOOGL. This is not fresh inflow, it is entrenched positioning. The consensus is so extreme that there are few new buyers left to push prices higher.
Japan: Foreign investors (gaijin) net buying +¥187B per week, positive for the second consecutive week. This is sustained institutional accumulation — smart money rotating into Japanese equities. Domestic retail buying +¥794B confirms the trend.
Vietnam: Foreign net buying +10.3M shares. But the detail matters: heavy accumulation in banks (KDH +8.0M, HDB +4.3M, EIB +3.6M, DGC +2.7M, STB +2.2M, TPB +2.1M). Heavy distribution in tech and select names (FPT -8.8M, SHP -5.2M, ACB -4.6M, HPG -2.8M). Smart money is rotating within Vietnam, not just buying everything.
Flow direction vs flow quality
Vietnam's net foreign buying (+10.3M shares) looks uniformly bullish at the headline level. But the stock-level data reveals a rotation: banks getting heavy accumulation while tech and steel get distributed. If you bought FPT because "foreign money is flowing into Vietnam," you would lose money — foreign money is flowing OUT of FPT. The aggregate number hides the sector-level story. Journely shows both.
Regime Classification: The Composite Picture
Five Dimensions, One Verdict
No single dimension determines regime. Volatility can be elevated while credit is stable (US). Flows can be bullish while breadth is narrow (Japan). The regime classification comes from weighing all five dimensions together — and identifying which conflicts need resolution.
US: RISK-OFF TO NEUTRAL. Volatility elevated (VIX 85th percentile), sentiment fearful (36.3), but breadth strong (A/D 9.5) and credit stable (+64bp curve). The fear is concentrated in sentiment, not in fundamentals. Sector rotation underway: Energy (+14%), Utilities (+10%), and Materials (+10%) leading while Tech (-4%), Financials (-5%), and Consumer Discretionary (-5%) lag. Oversold growth stocks are the opportunity.
Japan: RISK-ON BUT OVERBOUGHT. Foreign flows accumulating (+¥187B/week), Nikkei +6% monthly, but breadth narrow (A/D 0.18), RSI overbought (72), and JGB curve inverted (recession warning). The rally is real but vulnerable to pullback. Wait for RSI below 60 before adding exposure.
Vietnam: RISK-ON. Broad breadth (A/D 1.7, 52% of stocks rising), foreign accumulation (+10.3M shares), clear sector rotation into banks and industrials. The cleanest risk-on setup of the three markets — but requires following the flow data at the stock level to avoid distributed names.
How Regime Changes Every Other Signal
The same data point means different things in different regimes:
- P/E of 7x — in Vietnam's risk-on regime with foreign accumulation, ACB at 7x P/E is a genuine value opportunity. In a risk-off regime with capital fleeing, the same 7x could fall to 5x
- RSI of 40 — in the US risk-off-to-neutral regime, SPY's RSI 40 is an oversold buying opportunity (credit stable, breadth strong). In a true risk-off regime with widening credit spreads, RSI 40 would be a waypoint to RSI 20
- Foreign accumulation — in Japan's overbought regime, +¥187B/week foreign buying supports the rally but does not prevent a pullback. In Vietnam's clean risk-on regime, the same foreign buying is a stronger signal because breadth confirms it
- VIX at 21 — with credit stable and breadth strong, the elevated VIX is a fear premium that creates opportunity. With credit spreads widening, the same VIX would signal genuine systemic stress
What Makes This Different
- Five dimensions quantified across three markets — volatility (VIX 20.82, Nikkei 31.9%, Vietnam limit hits), sentiment (Fear 36.3, Japan gaijin +¥187B, Vietnam +10.3M shares), breadth (US 9.5, Japan 0.18, Vietnam 1.7), credit (US +64bp normal, Japan inverted), and flows with stock-level detail
- Conflicts flagged, not hidden — Japan's equity rally vs inverted yield curve. US fear sentiment vs strong breadth. Vietnam's net buying vs FPT distribution. Regime analysis that hides conflicts gives false confidence
- Sector rotation mapped — US rotating from growth (Tech -4%, Financials -5%) into defensives (Energy +14%, Utilities +10%). Japan led by mining and semis (+11%) while tech services collapses (-18%). Vietnam rotating from tech into banks. The rotation tells you where the regime is headed
- Stock-level flow data — not just "foreign money entering Vietnam" but KDH +8.0M, HDB +4.3M vs FPT -8.8M, ACB -4.6M. The aggregate hides the reality; Journely shows both levels
- Every data point is live — February 16, 2026 VIX, yield curves, foreign flow data, sector performance, advance/decline ratios. Real regime analysis, not a textbook framework applied to historical examples
