What a bull market is
The conventional definition is a rise of 20% from a low. That is a description after the fact, not a signal. A more useful working definition is a period in which the majority of stocks are trending higher, credit conditions are easing or stable, and pullbacks are bought rather than sold. The distinction matters because a 20% rally in a handful of very large companies can lift an index while most stocks go nowhere.
Felix's approach is to look at breadth first: the proportion of stocks above their 200 day moving average, the number of new highs against new lows, and whether smaller companies and cyclical sectors are participating. A rally with narrow leadership is fragile. A rally that broadens is a regime change.
What tends to lead
Early in a new cycle, the leaders are typically the sectors that were most punished in the preceding decline and the companies most sensitive to an improvement in credit and growth. Later, leadership often rotates towards quality and earnings growth. Watching where leadership sits is one way of estimating how far a cycle has progressed.
Policy is the other input. Bull markets have historically begun while economic news is still poor, because markets respond to the change in the rate of deterioration and to central bank easing rather than to the level of activity. Waiting for the economic data to confirm the recovery has historically meant missing a substantial part of the early advance. The Goat Academy insights on reading rate decisions and the yield curve discuss this in detail.
Errors investors make early in a cycle
- Anchoring to the low. Investors who missed the bottom often wait for a return to it, which may never come, and end up buying much higher after the evidence is undeniable.
- Fighting the trend on valuation alone. Markets can remain expensive for years in a rising regime. Valuation is a poor timing tool.
- Chasing the narrowest leaders. Buying only the stocks that have already risen most concentrates risk in the part of the market most vulnerable to a rotation.
- Abandoning risk management. A rising market rewards leverage until it stops, and it stops without warning. Position sizing rules should not change with the regime.
- Confusing a bear market rally with a new bull market. Sharp rallies within a decline are common. Breadth and credit help distinguish them from a genuine change.
How the framework changes with the regime
In a confirmed rising regime, Felix's framework shifts in three ways. Pullbacks are treated as opportunities to add to positions at defined levels rather than as warnings. Exposure moves towards the sectors that are leading rather than those that are cheapest. And the time horizon for holding winners lengthens, with exits driven by a change in the regime rather than by a price target.
What does not change is the discipline: written rules, position limits, and a review process that runs on a schedule. Felix uses Winston, the market intelligence tool he developed, to track the breadth, credit, and policy indicators that inform the regime assessment each day. The Wall Street Protocol teaches the full framework, including how to recognise the transition from one regime to the next.
Nothing on this page is a forecast. Regimes can reverse, and a framework for recognising a bull market is not a promise that one is under way or will continue.
Key points
What to take from this guide
- 01Define a bull market by breadth, credit, and behaviour around pullbacks, not by the 20% rule.
- 02Leadership typically begins in the most punished sectors and rotates towards quality later.
- 03Markets have historically turned before the economic data, which is why waiting for confirmation is costly.
- 04The framework adapts to the regime; position sizing and written rules do not.
