Reading the Market

Valuation tells you what to buy; this lesson helps with when, and with confirming or challenging your thesis. You’ll learn to read four kinds of market signals — price action, smart-money positioning, events, and the macro backdrop — always as clues about probability and positioning, never as certainty.

What you’ll learn

• The basics of technical analysis: trend, support/resistance, moving averages, RSI, MACD, and volume
• How to read “smart money”: insider buying, institutional 13F moves, short interest, and options signals
• How earnings calls and forward catalysts can move a stock
• How the macro regime (rates, inflation, the cycle) favors different sectors and styles
• Why no single signal is decisive — and why agreement across signals raises confidence

First, a framing

Everything in earlier lessons answered what is a good business at a fair price. Market signals answer a different question: what is the crowd doing, and when might the market agree with my thesis?

Key idea: Market signals are about probability and positioning, not certainty. A great chart on a bad business is a trap; a strong business at a great valuation with the market signals lining up is a higher-confidence setup. Signals tilt the odds — they don’t guarantee outcomes.

Read this lesson as a toolkit for timing and confirmation, layered on top of fundamentals and valuation.

1. Technical analysis basics

Technical analysis studies price and volume history to judge the balance of supply and demand — where buyers and sellers are likely to act. It says nothing about whether a business is good; it’s about behavior and timing.

Trend: up, down, or sideways

The single most important read is the trend — the general direction of price over time.

Key idea: “The trend is your friend.” Trading with the prevailing trend puts the odds on your side; fighting it is harder.

Support and resistance

• Support — a price level where buying tends to appear and halt a decline (a “floor”).
• Resistance — a level where selling tends to appear and cap a rise (a “ceiling”).

Think of them as memory: prices where lots of trading happened before, so buyers and sellers react again. When price finally breaks through resistance on strong volume, that old ceiling often becomes the new floor.

Moving averages (50-day and 200-day)

A moving average (MA) smooths price by averaging the last N days, so you see the trend without the daily noise. Two are widely watched:

• The 50-day MA tracks the medium-term trend.
• The 200-day MA tracks the long-term trend.

When the shorter average crosses the longer one, traders take note:

These are lagging signals — they confirm a turn after it has begun, rather than predicting it.

Momentum oscillators: RSI and MACD

Momentum measures how fast price is moving. Two common gauges:

• RSI (Relative Strength Index) runs from 0 to 100. As a rule of thumb, above ~70 is overbought (risen fast, may be due for a pause), below ~30 is oversold (fallen fast, may be due for a bounce). In a strong trend, though, RSI can stay “overbought” for a long time — it’s a caution flag, not a sell button.
• MACD (Moving Average Convergence Divergence) compares two moving averages to show whether momentum is building or fading. When its line crosses above its signal line, momentum is turning up; below, turning down.

Volume confirms

Volume — the number of shares traded — tells you how much conviction is behind a move. A breakout on heavy volume is more trustworthy than one on thin volume, which may fizzle.

Key idea: Technicals describe probabilities and timing, not intrinsic value. A chart can tell you the crowd is buying; it cannot tell you the business is worth the price. Use it alongside fundamentals, never instead of them.

In the plugin: the technical-analysis skill reads trend, support/resistance, and indicators; the chart-master skill draws the visuals (MA lines, RSI/MACD, volume, candlesticks).

2. Sentiment and smart-money positioning

Beyond the chart, you can watch what informed players are actually doing with their money. These signals reveal positioning and sentiment.

Insider trading (SEC Form 4)

Company insiders — executives and directors — must report their trades to the SEC on Form 4 within two business days. This is public.

• Insider buying is the stronger signal. Insiders sell for many reasons (taxes, a house, diversification), but they generally buy for only one: they think the stock is cheap.
• Insider selling is noisier and often routine, so read it with more caution.

Key idea: A cluster of insiders buying with their own cash — especially after a price drop — is a meaningful vote of confidence.

In the plugin: the insider-trading skill parses Form 4 filings and flags notable buying or selling.

Institutional ownership (13F filings)

Large investment funds (over $100M) must disclose their holdings quarterly on a 13F filing. This lets you track what big, well-resourced “smart money” is adding to or trimming from their portfolios.

The signal is in the change: a respected fund building a new position, or several institutions accumulating a stock, suggests conviction. Note the ~45-day reporting lag — 13F data shows where the money was, not where it is today.

In the plugin: the institutional-ownership skill tracks 13F changes to spot accumulation and distribution.

Short interest and the squeeze

Short interest is the number of shares that traders have sold short — borrowed and sold, betting the price will fall. High short interest means many are bearish.

But it cuts both ways. If a heavily-shorted stock starts rising, short sellers must buy back shares to cut losses, and their buying pushes the price higher still — a short squeeze. A useful gauge is days-to-cover: short interest divided by average daily volume, estimating how long it would take shorts to buy back. Higher = more squeeze fuel.

In the plugin: the short-interest skill measures bearish positioning and squeeze potential.

Options signals

The options market — contracts to buy (calls) or sell (puts) a stock at a set price — reveals expectations and hedging.

• Implied volatility (IV) is the market’s expectation of how much a stock will move, baked into option prices. High IV means big moves are expected (often around earnings); it makes options expensive.
• Put/call ratio compares put volume to call volume. A high ratio (lots of puts) signals fear or hedging; a low ratio signals optimism. Extremes can be contrarian — everyone bearish sometimes marks a bottom.
• The Greeks in one line: they measure an option’s sensitivity — delta to the stock’s price, theta to time decay, vega to volatility. They tell you what drives an option’s value.

In the plugin: the options-analysis skill reads IV, the put/call ratio, and the Greeks.

3. Events and catalysts

Stocks often move in jumps around events. Knowing the calendar helps you anticipate volatility and check your thesis.

Earnings calls

Every quarter, a company reports results and management holds an earnings call. Three things move the stock:

• Surprises — results above or below what analysts expected. Beating on revenue and profit usually helps; missing usually hurts.
• Guidance — management’s forecast for coming quarters. Often this matters more than the reported numbers, because markets look forward.
• Tone — the language and confidence of management. Hesitation, hedging, or defensiveness on the call can undercut good numbers.

In the plugin: the earnings-call-analysis skill reads a transcript for sentiment, key themes, and management tone.

Forward catalysts

A catalyst is a known upcoming event that could move the stock: a product launch, a drug approval or trial result, a major contract, an index inclusion, or a macro data release (a “print”) like a jobs or inflation report. Mapping these ahead of time tells you when volatility — and opportunity or risk — is likely to cluster.

Key idea: Catalysts don’t tell you which way a stock will move, but they tell you when it’s likely to move a lot. That’s valuable for sizing and timing.

In the plugin: the catalyst-calendar skill builds a forward calendar of events and their expected impact.

4. Macro and sectors (top-down)

Individual stocks swim in a bigger current: the macro regime — the state of interest rates, inflation, and the economic cycle. Reading it top-down tells you which styles and sectors have the wind at their back.

The key macro dials

• Interest rates — set largely by the central bank. Higher rates make borrowing costlier and make safe bonds more attractive versus stocks, which tends to pressure prices — especially for long-duration growth stocks (whose value depends on profits far in the future).
• The yield curve — a plot of bond yields across maturities. Normally longer bonds yield more. When it inverts (short yields exceed long), it has historically been a warning sign for recession.
• Inflation — rising prices. High inflation often pushes the central bank to raise rates, squeezing valuations.
• Leading indicators — data that tends to move before the economy, like new orders, building permits, or jobless claims, hinting at where the cycle is headed.

How regimes favor different sectors

Different parts of the economy do better at different points in the cycle. Roughly:

Sector rotation is the tendency of money to flow from one group to another as the regime shifts — for example, out of high-growth tech and into defensives as rates rise and the cycle matures.

In the plugin: the economics-analysis skill reads the regime (rates, inflation, indicators); the sector-analysis skill maps that regime to the sectors likely to lead. See Concepts on “Macro regimes” for the bigger picture.

Illustrative example

Suppose (hypothetically) the central bank is raising rates to fight 5% inflation, and the yield curve has just inverted. Top-down, you’d expect long-duration growth stocks to face a headwind and defensives to hold up better. That doesn’t mean sell everything — it means you’d demand a higher margin of safety on richly-valued growth names and weight the macro against your thesis. Numbers here are round and hypothetical.

Putting the signals together

No single signal is decisive. Each one — a golden cross, a cluster of insider buys, a beat-and-raise, a friendly macro regime — nudges the odds. The strongest reads come when they agree.

Key idea: Confidence should rise when fundamentals, valuation, and market signals point the same way — and drop when they conflict. A cheap, high-quality business with insiders buying and the sector in favor is a much higher-confidence idea than any one of those alone.

When signals disagree — say, great fundamentals but a broken chart and a hostile macro — that’s not a reason to ignore the conflict; it’s a reason to lower your confidence, size smaller, or wait. This is exactly the logic behind InvestSkill’s signal blocks and its emphasis on confidence. See Concepts for how the plugin combines signals into a single, honest read.

Key takeaways

• Market signals are about probability, timing, and positioning — not certainty, and never a substitute for valuing the business.
• Technicals (trend, support/resistance, MAs, RSI, MACD, volume) describe crowd behavior; use them to confirm timing, not to judge worth.
• Smart-money signals — insider buying (stronger than selling), 13F accumulation, short-squeeze setups, options IV and put/call — reveal how informed players are positioned.
• Events (earnings calls) and forward catalysts tell you when a stock is likely to move a lot; the macro regime tells you which sectors and styles have the wind at their back.
• Confidence is highest when fundamentals, valuation, and market signals agree — and should fall when they conflict.
