What is a Bull Market? Key Information about Bull Markets

Stock market bulls are back in control as major US indices have soared to new all-time highs to start 2024. Despite apprehension over inflation and high rates, bullish market trends have overtaken these concerns, in no small part thanks to exuberance over artificial intelligence innovation. But what is a bull market in stocks exactly, and how should investors react to these new highs? In this article, you’ll learn the technical bull market definition, how to trade a bullish Stock market and what a bull market means for the broader economy.

Key Takeaway

Empirically, a bull stock market is an advance of 20% or more in an index or security, often resulting in new all-time highs. A bull run in stock markets is usually accompanied by positive investor sentiment, an expanding economy and an increase in risk appetite.

Understanding Bull Markets

What is a bull market? For most investors, it's good news—stocks are going up. Bull markets elevate investor sentiment and frequently (but not always) coincide with improving economic data. They vary in length but can often last for years.

Causes of Bull Markets

• Expanding GDP
• Low unemployment 
• Technological advances
• Declining interest rates

Characteristics of Bull Markets

• All-time highs in stock indices
• Increasing retail sales
• Positive investor sentiment
• Rotation into riskier market sectors

Anatomy of a Bull Market

To truly define a bull market, we’ll need to discuss investor sentiment. Investor sentiment tends to flow similarly during bull runs, starting with institutional investors and moving through media to retail investors. 

Several factors can enhance investor sentiment during bull markets, such as improving economic data, declining inflation or lower interest rates. Bull markets can take years to flow through market participants before capital becomes depleted or the economy stumbles.

Examples of Historic Bull Markets

Here are some famous bull markets in the United States from the last 100 years:

The Roaring 20s

The bull market preceding the Great Depression saw incredible wealth creation and cultural expansion. Jazz was born, women gained suffrage, and the economy roared for nearly a decade until the Crash of 1929.

Dot Com Boom 

Tech stocks soared to unprecedented levels with the birth of the Internet in the early 1990s. By 2000, the NASDAQ had gained over 800% in about 5 years, creating a speculative bubble few markets had seen before.

Post-GFC Bull Market

Stocks suffered in ways not seen since the Great Depression in 2009, but one of the longest bull markets in history soon followed. The S 500 went more than 9 years without suffering a 20% drop and posted positive returns for six consecutive years.

Key Drivers Behind Bull Markets

Bull markets share specific characteristics, but different factors drive each one. For example, the bull market following the Great Recession was aided by loose monetary policy, as interest rates were near zero until 2017. However, rates were above 5% for the Dot Com boom, and investors still couldn’t get enough of tech stocks.

Since no 2 bull markets are alike, let’s analyze all potential drivers and factors: 

• Fiscal Policy: When Congress authorized the Treasury to send economic impact payments to Americans during COVID, that was an example of fiscal policy. Fiscal policy comes from Congressional spending or taxation.
• Monetary Policy: Action from the Federal Reserve is called monetary policy, which comes from interest rate adjustments and open market operations. An excellent way to differentiate fiscal and monetary policy is to think of fiscal policy as targeting demand while monetary policy targets supply.
• Technological innovation: Exuberant investors often reward revolutionary technology. And while the Dot Com bubble was loaded with hubris, the internet’s rise was indeed a world-changing event. From the printing press to the assembly line to the iPhone, innovation that drives the economy forward can often be what defines a bull market.
• Geopolitical stability: Tension between nations can often disrupt markets. For example, Russia’s invasion of Ukraine in 2022 sent oil prices skyrocketing for several weeks as supply concerns spilled onto the world stage. 

Bull Market vs. Bear Market: What's the Difference?

A bear market is a 20% decline in a market average or security, which frequently happens quicker than a bull market upturn. Stocks are commonly said to take the stairs up but the elevator down, hence year-long bull runs followed by crashes.

Bear markets also occur for a number of different reasons, such as crumbling investor sentiment, poor economic data, government policy errors or geopolitical strife. But it’s important to remember that bear markets (and bear market rallies) are a natural part of the market cycle, and investors with risk controls have no reason to fear them. 

Investing Strategies for Bull Markets

Investors can get FOMO during bull markets, often to their detriment. When times are good, ignoring risk tolerance rules and getting bolder with your investments is easier. But the bull market never lasts forever, and unless you’re an elite market timer, you need strategies to work in both bull and bear markets. Here are a few to consider when market averages are heading up:

• Growth investing - During bull markets, value stocks are the Rodney Dangerfield of the exchanges: they get no respect. Bull markets create conditions where growth stocks prosper since investors are willing to forgo current profits for future promises.
• Momentum trading - Using a momentum strategy is a famous bull trading technique since volatile stocks often create profitable opportunities. Technical tools like moving averages, support and resistance and oscillators like Relative Strength Index (RSI) can be helpful when riding bull market momentum waves.
• Sector rotation - When sentiment is high, investors look for bull stocks, meaning sectors like tech and consumer discretionary. Investors rotate from safer sectors like utilities and staples when indices rise, and vice versa during bear markets.

Risks and Challenges in Bull Markets

A stock market bull can get complacent over time, ignoring warning signs in search of higher profits. That’s not to say you should invest timidly, but understanding risk means having rules to prevent portfolio disaster. After all, what’s a bull market without a few complacent participants? 

Here’s an example- many investors are currently overweight tech thanks to incredible gains from the semiconductor sector. Companies like NVIDIA Corp. (NASDAQ: NVDA) have lofty valuations, but how do you know when to sell? Instead of looking for market signals, consider selling shares of any stock that grows over 30% of your portfolio. Rules create diversified portfolios and prevent investors from panic-selling during downturns.

How to Take Advantage of a Bull Market

Here are a few methods to maximize returns during a bull market in stocks:

Evaluate Your Portfolio’s Risk Level

Is your portfolio too conservative for a bull run? You shouldn’t leap into volatile tech stocks, but too little risk can leave your portfolio underperforming.

Rotate Asset Allocation

If you find your risk level lacking, consider a sector rotation. During bull runs, growth-focused sectors often outperform.

Don’t Time the Market

Trying to pick market tops and bottoms is a fool’s errand. Market timing is one of the worst ways to mismanage a portfolio, and emotions often get the best of investors who lack a rules-based plan.

Bull Markets Are Exuberant Times, But Don’t Ignore Risk

All-time market highs characterize a bull market, an expanding economy and improved investor sentiment. However, bull markets aren’t an excuse to throw caution to the wind and buy up every hot stock profiled on CNBC. Make sure to reevaluate your goals during bull markets to avoid any ‘irrational exuberance’.
