Events & catalysts

Markets don't move randomly. Most of the volatility on any given day is concentrated in a few scheduled or expected events: earnings, Fed decisions, macro data releases, sector-specific catalysts, and idiosyncratic surprises. Understanding the structure of these events — and what's already priced in — is the difference between positioning intelligently and getting run over.

Earnings

Roughly 4 times a year, every public company reports its results. The reaction to earnings is often the largest single-day move a stock will make all year. Three things move:

• The number itself — EPS and revenue beat / miss / in-line vs analyst consensus.
• Forward guidance — the company's own forecast for next quarter or year. Often more important than the trailing print.
• Conference call commentary — what management says, questions analysts ask, what gets dodged.

BMO vs AMC

US companies report either before market open (BMO) or after market close (AMC). Different dynamics:

• BMO — pre-market trading reacts immediately. The regular session opens with the gap already priced in. Liquidity is thin, spreads are wide; many traders avoid the first 30 minutes.
• AMC — after-hours trading reacts on lower volume. The next-day open often re-prices significantly as institutional flow returns. The "earnings reaction" you read in the news is often the after-hours gap; the regular-session move can be very different.

Beat-and-raise vs in-line

Not all beats are equal. A beat with raised forward guidance ("beat-and-raise") signals that the next quarter will also beat — analysts revise estimates up, and the stock often drifts higher for weeks (see PEAD). An in-line beat with unchanged guidance fades within days; the surprise has been priced in.

IV crush

Implied volatility (IV) on options rises into earnings — uncertainty about the print pumps option premiums. The moment the report drops, that uncertainty resolves, and IV collapses. Long options positions held through earnings often lose money even when the trader was right on direction, because IV crush eats more than the price move adds. Pros use earnings volatility differently — selling premium into the print, or using ratios that benefit from volatility collapse.

The post-earnings drift window

Whether you traded the earnings or not, the following 4-8 weeks often has tradeable structure. Beat-and-raise names tend to drift up on a clear pivot above pre-earnings highs; misses tend to grind lower as analysts cut estimates and forced sellers (active funds with risk constraints) work out of the position.

FOMC days

The Federal Open Market Committee (FOMC) sets US interest-rate policy. Eight scheduled meetings per year, plus occasional emergency moves. The statement is released at 2:00pm ET; the chair's press conference begins 30 minutes later.

The market typically does most of its day's move between the statement release and the press conference's end (around 3:30pm ET). Often the initial reaction reverses during the press conference — the statement and the chair's tone can diverge. Trading the first 30 minutes after the statement is high-variance work; many pros wait until the press conference ends.

Things to know

• Dot plot — quarterly summary of where each FOMC member sees rates over the next 1-3 years. Released at the March, June, September, December meetings. Often more important than the rate decision itself.
• Blackout window — Fed officials go quiet for ~10 days before each meeting. No speeches, no interviews. Reduces macro signal flow during that window.
• Press conference questions — journalists' questions can pull the chair off-script and move markets unpredictably.

Positioning around FOMC

The honest pro answer: reduce or hedge into Fed days. Not because you don't have a view, but because the variance of outcomes is wider than your view's edge. Even pros who trade FOMC events systematically size much smaller than usual. The retail trader's default should be "don't add new exposure on Fed day; let positions ride if they're working".

Macro releases

Beyond FOMC, several data releases routinely move equities:

CPI / PCE — inflation prints

Released monthly. CPI is the headline; PCE is what the Fed actually targets. A hotter print (above consensus) pushes the expected rate path higher, hurts long-duration assets (growth stocks), and can crater the bond market. A cooler print does the opposite. Core CPI (ex food & energy) is the number that moves markets most; supercore (services ex housing) is the Fed's current obsession.

Nonfarm Payrolls (NFP)

First Friday of every month, 8:30am ET. The headline jobs number plus unemployment rate plus average hourly earnings. The Fed's dual mandate is inflation and employment — strong NFP with rising wages = harder for the Fed to cut rates = bad for growth stocks. Cooling NFP = rate cuts back on the table = bond rally and growth bid.

ISM PMI — Manufacturing & Services

Monthly diffusion indices. Above 50 = expansion; below 50 = contraction. Useful for spotting recession risk and sector rotation early. ISM Manufacturing has historically led the cycle by 3-6 months.

Initial jobless claims

Weekly. Less market-moving than NFP, but a sustained spike above 300k starts to register as a labor-market crack worth watching.

Sector-specific catalysts

Different sectors have their own cyclical events. Some that matter:

• Semis — TSM monthly revenue (mid-month), AMAT/LRCX bookings on earnings, NVDA earnings as bellwether for AI infra.
• Energy — OPEC+ meetings, weekly EIA oil inventories (Wednesdays), summer-driving and winter-heating demand cycles.
• Banks — Q-end stress tests, Fed decisions on capital buffers, yield curve shape.
• Consumer disc. — monthly retail sales (Census Bureau), Black Friday / holiday season reads, gas-price impact on discretionary spend.
• Pharma / biotech — FDA approval calendars, ASCO/ AHA conference data drops (May/June, November), Phase 3 readouts.
• Healthcare insurance — Medicare Advantage rate announcements (Q1 each year), CMS rule changes.

If you trade names in any sector, knowing its calendar is non-optional. The Khabir Week ahead page surfaces the next week's catalysts; the Week review page recaps what landed.

Idiosyncratic events

Insider buying clusters

When 3+ company insiders buy open-market shares within 30 days, that's a cluster — and historically a meaningful signal. Insiders selling is noise (most exec comp is in stock; selling is rebalancing). Insiders buying with their own cash, especially in size, tells you they think the stock is mispriced lower. Required filing: SEC Form 4. The signal is strongest when the buying includes the CEO or CFO and exceeds aggregate $500k.

13F filings — institutional positions

Quarterly disclosures (45-day lag) of US institutional holdings > $100m. Lagging — the data is 45-90 days old by the time it's public — but useful for spotting accumulating positions in specific names. Hedge fund "13F-following" strategies have a small documented edge (Cohen, Polk, Silli 2010); too small to trade alone, but useful as one input among many.

Analyst rating changes

Upgrades and price-target raises move stocks, especially from a major broker (GS, MS, JPM). The first upgrade after a long downtrend often marks an inflection. Subsequent upgrades have diminishing impact.

Index inclusion / exclusion

S&P 500 inclusion announcements drive forced buying from index funds tracking the index. The "front-running" trade — buying ahead of the inclusion date — used to be reliable; in recent years it has become more noisy as more participants anticipate it. Exclusions are symmetric.

Practical preparation

A reasonable weekly preparation routine:

1. Sunday evening: open Week ahead. Note the macro calendar, earnings calendar, and any events touching names you hold or watch.
2. Block out high-impact days. Decide in advance whether you'll add risk on FOMC day or stand down. Decide in advance whether you'll hold a position through its earnings.
3. Set alerts for macro releases that could affect sector exposure. CPI day if you're long growth; OPEC weekend if you're long energy.
4. Review after the week with Week review: what landed, what surprised, how the screen performed.

Key takeaways

• Most volatility is event-driven and predictable in its timing, if not its direction.
• Earnings: beat-and-raise > in-line beat. IV crush punishes long options through earnings.
• FOMC: reduce risk into the meeting; trade the press conference, not the statement reaction.
• Macro: CPI and NFP are the moving prints; ISM PMI is the leading indicator.
• Insider clusters with CEO/CFO buying and ≥ $500k aggregate are among the best contrarian signals available.
