US Stocks: A Knowledge Briefing — October 8
The market presented a split picture today
The VIX closed at 15.08
But take a look at crypto, and you’ll see these losses:
BTC -1.83%
ETH -2.0%
MSTR -6.79%
COIN -3.92%
MARA -5.56%
US stocks are steady, but crypto is already crashing
Let’s use this to talk about the VIX
I. What is the VIX?
VIX stands for the CBOE Volatility Index
It measures the expected annualized volatility of the S&P 500 over the next 30 days
It uses S&P 500 index option prices to infer how the market is pricing future volatility
Expensive options mean people are on edge, so the VIX is high
Cheap options mean people are relaxed, so the VIX is low
II. The VIX’s five-level thermometer
VIX below 15: extremely calm
VIX 15–20: normal volatility
VIX 20–30: tension is starting to build
VIX above 30: truly intense volatility, usually accompanied by a sharp market drop
VIX above 50: financial-crisis levels
2008 peak: 80.86
2020 pandemic: 82.69
III. The real relationship between the VIX and BTC
Many people think that if the VIX rises, BTC must fall. That’s wrong
The VIX measures US stock market volatility and does not include crypto assets at all
It’s possible for the VIX to be calm while BTC plunges
Historically, the rolling correlation between BTC and the VIX has been 0.3–0.5
There’s only one thing that truly makes both fall: a broad recovery in global risk appetite
There’s only one thing that truly makes both rise: a liquidity crisis
IV. Why are crypto prices falling while US stocks aren’t?
1. There’s no systemic risk in US stocks
All three major indexes are still up over the past 5 days
Nasdaq up 2.5%
S&P 500 up 1.8%
2. The crypto market is under pressure of its own
IBIT is down 1.6% over 5 days, with ETF funds flowing out
3. High-beta crypto stocks are being liquidated
MSTR/COIN/MARA are facing concentrated liquidations, magnifying their losses
4. MSTR is down 6.79%, while BTC is down only 1.83%
That suggests high-beta positions are being unwound, not that BTC itself is collapsing
V. Tips for trading crypto
1. Keep a close eye on IBIT
IBIT is BlackRock’s BTC ETF
It’s the clearest barometer of institutional money
A 1.6% outflow over 5 days is mild, not a massive sell-off
2. The plunge in MSTR/COIN/MARA is a high-beta liquidation
Once the liquidations are over, BTC will stabilize before they do
3. A low VIX means the macro environment is giving crypto some breathing room
It gives BTC a window to recover on its own
Don’t scare yourself
4. Pay close attention to the US market open tonight
If the VIX suddenly climbs above 20, that’s when you should really be on alert
In short:
The VIX is a thermometer for US stocks, not crypto
US stocks not running a fever doesn’t mean crypto isn’t sick
But as long as the VIX doesn’t explode,
BTC’s declines are a structural shakeout, not a systemic collapse
Crypto veterans all know
The real risk has never come from crypto itself
It’s when US stocks next door suddenly come down with a fever
US stocks didn’t get a fever today, so don’t panic
