The problem

You wake up to a market already down 4%.
You had no warning.

By the time most investors check their phones, the damage is done. Asia crashed overnight, Europe followed, and your market opened deep in the red — while you were asleep.

7:32 AM — You wake up

S&P 500 opens down −3.8%

You had no idea

With MarketBell

3:14 AM — Email arrives

🔴 Asia-Pacific is CRASH · −4.2% avg · 9 of 9 markets declining · Europe opens in ~2 hours

You wake up informed

You already know. You've had hours to think about your next move before the bell rings.

How it works

The early warning chain

Markets open in sequence across time zones. A crash in Asia is your earliest warning before Europe opens — and before Wall Street rings the bell.

STEP 01

Asia closes

At 6am UTC, we scan all 9 Asia-Pacific markets. If the region shows significant breadth-confirmed selling — more than 60% of markets declining with a −2%+ average — an alert fires.

6:00 AM UTC

STEP 02

Europe mid-session

At 1pm UTC (30 min before Wall Street opens), we scan Europe. If European markets are crashing mid-session, Americas subscribers get one final warning before their bell rings.

1:00 PM UTC

STEP 03

You wake up ready

You receive a clear email: which region, which markets, the average % move, and how many minutes before your market opens. No noise on calm days — only signal when it matters.

FAQ

Common questions

How is this different from CNN Fear & Greed Index? ▼

CNN Fear & Greed measures US market psychology using 7 indicators including VIX and put/call ratios. MarketBell measures something different — what percentage of the world's major markets are advancing or declining right now, across every time zone. Our unique value is the early warning chain: Asia closes → email fires → you know before Europe opens.

How often will I receive emails? ▼

On most days — nothing. Alerts only fire when markets show genuine breadth-confirmed significant moves. Based on historical data, a −2% average across a region only happens a handful of times per year. You will not be spammed with daily updates.

What times do alerts fire? ▼

Three windows on weekdays: 6am UTC (Asia closes, Europe about to open), 1pm UTC (Europe mid-session, 30 min before Wall Street opens), and 2pm UTC (global check as Wall Street opens). Sunday 1pm UTC for Middle East post-close warnings before Monday's Asia open.

Is this really free? ▼

Yes, completely free. No credit card, no trial period, no hidden costs. We may introduce a premium tier in the future with additional features, but the core early warning alerts will always have a free option.

Can I change my preferences after subscribing? ▼

Yes — every alert email contains an "Update preferences" link. Click it to adjust your regions, threshold, or direction settings. No login required — the link is authenticated via a unique token tied to your email.

What data sources do you use? ▼

Live prices are sourced from Finnhub via ETF proxies that track each major index. The sentiment gauge uses an advance/decline breadth formula consistent with methods used by Charles Schwab and LPL Research.
