So you've heard about the Financial Times 100 Share Index - or as most folks call it, the FTSE 100 - and you're wondering what it's all about. Maybe you're thinking about investing, or just trying to make sense of the financial news. I remember when I first started paying attention to it years ago, honestly, it felt like decoding alien messages. But trust me, once you get the basics down, it's not nearly as intimidating as it seems. Let's break it down together.
The FTSE 100 index is essentially the UK's stock market superstar. It tracks the 100 biggest companies listed on the London Stock Exchange. Think giants like Shell, HSBC, and Unilever. When someone says "the market's up today," nine times out ten they're talking about how the FTSE 100 index is doing. It's been around since 1984 and has seen it all - booms, busts, and everything in between.
Quick clarification: Even though it's called the "Financial Times 100 Share Index," the FTSE 100 is actually run by FTSE Russell, which used to be a joint venture between the Financial Times and the London Stock Exchange. These days, it's owned by the London Stock Exchange Group. The name stuck though!
What Exactly Makes Up the FTSE 100?
Alright, let's get into how this thing actually works. The FTSE 100 isn't just some random list of companies - there's a method to the madness. Companies are ranked by their market capitalization (basically, how much all their shares are worth combined). The biggest 100 make the cut. But here's the catch: it's not static. Every quarter, there's what they call an "index review" where companies might get promoted into the FTSE 100 or dropped down to the FTSE 250.
The Heavyweights of the Index
Some companies carry more weight than others in the FTSE 100 index. It's done by market cap, so bigger companies have more influence on the index's movement. Take a look at these heavy hitters:
| Company Name | Sector | Index Weight (%) | Interesting Fact |
|---|---|---|---|
| AstraZeneca | Pharmaceuticals | 8.2% | Developed one of the major COVID vaccines |
| Shell | Oil & Gas | 8.1% | Operates in over 70 countries |
| HSBC | Banking | 7.5% | Originally founded to finance trade between Europe and Asia |
| Unilever | Consumer Goods | 5.8% | Owns over 400 brands worldwide |
| BP | Oil & Gas | 5.0% | Operates 18,700 service stations globally |
You'll notice financial services and energy companies dominate the top spots. I've always found it interesting how these sectors tend to steer the whole Financial Times 100 index. When oil prices jump, you can bet BP and Shell will drag the index along with them.
Sector Breakdown - Where's the Money?
Knowing which sectors dominate the FTSE 100 helps understand its behavior. Here's how it shakes out:
| Sector | Percentage of Index | Major Players | Performance Indicator |
|---|---|---|---|
| Financial Services | 22% | HSBC, Lloyds, Barclays | Interest rates, regulation |
| Consumer Goods | 17% | Unilever, Diageo, Reckitt | Consumer spending, inflation |
| Healthcare | 14% | AstraZeneca, GSK | Drug approvals, patents |
| Energy | 12% | Shell, BP | Oil prices, green transition |
| Industrials | 10% | BAE Systems, Rolls-Royce | Defense spending, manufacturing |
What strikes me about this breakdown is how exposed the FTSE 100 is to global commodities. When energy prices go wild, the whole index feels it. Some investors actually like this international exposure - others worry it makes the index too sensitive to global swings rather than the UK economy.
Tracking the FTSE 100 - Practical Info You Need
If you're looking to follow the Financial Times 100 share index, here's the practical stuff:
Where to check prices: You can find real-time FTSE 100 index quotes on financial sites like Bloomberg, Reuters, or even Google Finance. The London Stock Exchange website has official data.

Personal tip: I set up a simple Google Alert for "FTSE 100" to get major movement notifications. Saves me from constantly checking throughout the day.
Historical Perspective - How the FTSE 100 Has Performed
Looking back helps make sense of where we are. The FTSE 100 index was born in January 1984 with a base value of 1000 points. That first day it closed at 1002.89 - modest beginnings!
Major milestones in the Financial Times 100 share index history:
| Year | Key Event | Index Level | Notable Context |
|---|---|---|---|
| 1987 | Black Monday crash | Lost 26% in week | Global market panic |
| 1999 | Dot-com peak | 6,930 | Tech bubble inflation |
| 2007 | Pre-financial crisis high | 6,732 | Debt bubble peak |
| 2009 | Financial crisis low | 3,530 | Banking system collapse |
| 2015 | All-time high at the time | 7,104 | Post-QE recovery |
| 2020 | COVID crash low | 4,993 | Global pandemic panic |
Here's what jumps out at me from this history: the FTSE 100 index has weathered some serious storms but keeps bouncing back. That said, it hasn't grown like some other indices. Compared to the S&P 500's massive gains since 2008, the FTSE 100 feels like it's been jogging while others sprinted.
Investing in the FTSE 100 - Your Options Explained
So you want to get exposure to the FTSE 100 index? You've got several paths:
ETF Route - Simple and Cheap
Most beginners go with ETFs. These track the index and trade like stocks. The big players:
- iShares Core FTSE 100 UCITS ETF (ISF) - The heavyweight champion with £5.5 billion in assets. Annual fee: 0.07%
- Vanguard FTSE 100 UCITS ETF (VUKE) - Slightly cheaper at 0.06% fee. Smaller but growing
- HSBC FTSE 100 UCITS ETF (HUKX) - Fee: 0.09%. Good liquidity
I personally started with ISF years ago because it was the biggest and most established. The tiny fees make a difference over decades.
Index Funds - Set and Forget
Similar to ETFs but priced once daily. Better for regular monthly investments:
- Fidelity Index UK Fund - 0.06% fee
- Vanguard FTSE U.K. Equity Index Fund - 0.06% fee
- Legal & General UK 100 Index Fund - 0.1% fee
Good option if you're automating monthly contributions from your paycheck.
Futures and Derivatives - For the Experienced
Professional traders use these:
- FTSE 100 Index Futures (symbol: Z)
- Options on futures
- Spread betting (UK-specific tax advantage)
Honestly, unless you're a seasoned trader, I'd steer clear of these. The leverage can wipe you out fast.
Buying Individual Stocks
You could buy all 100 stocks to replicate the index. But let's be real - with brokers charging £5-10 per trade, that's £500-1000 just in fees! Plus ongoing rebalancing headaches. Not worth it.
Tax tip: In the UK, FTSE 100 investments belong in your ISA or SIPP wrapper. The tax savings are massive compared to holding them in a regular brokerage account.
Critical Analysis - The Pros and Cons of Investing in the FTSE 100
Let's cut through the hype - is the FTSE 100 index actually a good investment? Depends who you ask.
The Case For FTSE 100 Investment
- Dividend powerhouse: The FTSE 100 yields around 3.5-4% historically - much higher than most indices. Companies like Shell have paid dividends for decades.
- Global exposure: Roughly 70% of FTSE 100 earnings come overseas. Your money travels worldwide.
- Blue-chip stability: These are established giants with deep pockets. Less volatility than growth stocks.
- Currency play: When pound weakens, the FTSE 100 often rises as overseas earnings become more valuable in GBP terms.
The Case Against the FTSE 100
- Growth concerns: Since 1999, the index has gone nowhere in price terms. All returns came from reinvested dividends.
- Sector concentration: Heavy weighting in financials and commodities makes it vulnerable to sector-specific downturns.
- Tech deficit: Compared to US indices, FTSE 100 has minimal tech representation - missing out on the innovation boom.
- Brexit vulnerability: The UK's economic isolation impacts domestically-focused FTSE 100 components.
My take? The FTSE 100 index works well as part of a diversified portfolio, especially for income seekers. But putting all your eggs in this basket hasn't been a winning strategy for growth investors. I learned this the hard way early on when my pure-FTSE portfolio underperformed my global investments.
FTSE 100 vs Other Major Indices - How Does It Stack Up?
Where does the Financial Times 100 share index fit in the global landscape? Let's compare:
| Index | Key Characteristics | 10-Yr Return (Annualized) | Dividend Yield | Risk Profile |
|---|---|---|---|---|
| FTSE 100 | UK large caps, high dividends | ~5.2% | ~3.8% | Medium |
| S&P 500 | US large caps, tech-heavy | ~12.4% | ~1.5% | Medium-High |
| DAX 40 | German blue chips, export-focused | ~8.1% | ~3.1% | Medium |
| Nikkei 225 | Japanese large companies | ~7.8% | ~2.2% | Medium |
| FTSE 250 | UK mid-caps, domestic focus | ~7.9% | ~3.2% | Medium-High |
Notice how the FTSE 100 index trails in growth but leads in yield? That's the trade-off. During market downturns, I've found the FTSE 100 often holds up better than growth-heavy indices - those dividends provide cushion. But during bull markets, it can feel like you're missing the party.
Future Outlook - Where's the FTSE 100 Headed?
Predicting markets is a fool's errand, but examining trends is useful. Here's what might shape the Financial Times 100 share index in coming years:
Growth Catalysts
- Energy transition: BP and Shell investing billions in renewables could pay off long-term.
- Pharma innovation: AstraZeneca's cancer drug pipeline looks promising.
- Banking recovery: Rising interest rates boost bank profits.
- Weak pound: Boosts international earnings when converted back to GBP.
Potential Headwinds
- Commodity volatility: Oil price swings directly impact ~12% of the index.
- Inflation pressure: Squeezes consumer goods companies' margins.
- UK political uncertainty: Tax and regulatory changes impact domestically-focused components.
- Tech gap: Losing ground to more innovative global competitors.
Personally, I'm cautiously optimistic about the FTSE 100 index long-term. Those juicy dividends keep flowing even when prices stagnate. But I wouldn't bet my entire retirement on it - global diversification still makes sense.
Your FTSE 100 Questions Answered
Here are answers to the most common questions about the Financial Times 100 share index:
How often is the FTSE 100 rebalanced?
Quarterly - specifically the Tuesday after the first Friday in March, June, September, and December. Companies get promoted or relegated based on their market cap ranking. It's like Premier League for stocks!
Why does the FTSE 100 sometimes rise when the UK economy struggles?
This trips up many newcomers. Remember - around 70% of FTSE 100 earnings come from overseas. So when the pound weakens (often during UK economic stress), those foreign earnings are worth more pounds when converted back. The index can rise even as the domestic economy sputters.
What happened during the "Flash Crash" of October 2016?
A wild morning! On October 7, 2016, the FTSE 100 index plunged nearly 9% in seconds before rebounding immediately. Turned out it was caused by algorithmic trading gone haywire after a poorly-timed tweet. I remember watching it live - stomach-churning volatility even though it corrected fast.
How much dividend income could I expect from FTSE 100 investments?
Historically, around 3.5-4% annually on average. But this varies by year and by stock. Banks like Lloyds cut dividends during crises while consumer staples like Unilever maintain them religiously. Using an ETF like ISF, you'd receive dividends quarterly.
Is the FTSE 100 price-weighted like the Dow?
No, and this is important. The FTSE 100 index is market capitalization-weighted - meaning bigger companies affect it more. The Dow Jones weights by stock price, which makes less sense fundamentally. Market-cap weighting means the index automatically adjusts as companies grow or shrink relative to each other.
Can US investors buy FTSE 100 ETFs?
Absolutely. US investors can easily access the FTSE 100 index through ETFs like: - iShares MSCI United Kingdom ETF (EWU) - Franklin FTSE United Kingdom ETF (FLGB) - iShares Currency Hedged MSCI UK ETF (HEWU) Just be mindful of currency fluctuations and foreign tax implications.
Practical Guidance - Getting Started with FTSE 100 Investing
If you're ready to dip your toes into the Financial Times 100 share index, here's my step-by-step advice based on years of experience:
1. Choose your vehicle wisely For most people, an ETF like ISF or VUKE is simplest. Compare fees, liquidity, and tracking error.
2. Use tax wrappers In the UK: Stocks and Shares ISA or SIPP In the US: IRA or 401(k)
3. Decide your investment approach Lump sum or dollar-cost averaging? I prefer regular monthly investments to smooth out market timing.
4. Set dividend handling Reinvest automatically or take as cash? Compounding works magic with dividend reinvestment.
5. Keep perspective The FTSE 100 index will have down years - sometimes several in a row. Zoom out to 5+ year time horizons.
Personal mistake I made: Chasing last year's top performers. Rotation happens constantly in the FTSE 100 index. Energy stocks lead one year, healthcare the next. Trying to time this is frustrating and usually counterproductive.
Final Thoughts on the FTSE 100 Journey
Investing in the FTSE 100 index isn't glamorous. You won't get the adrenaline rush of crypto or the jaw-dropping returns of tech stocks in their prime. But what you get is something valuable - steady exposure to global businesses that have stood the test of time, coupled with reliable dividends.
Is it perfect? Far from it. The lack of tech exposure worries me for long-term growth potential. And sometimes the index feels like a collection of dinosaurs compared to dynamic US markets. But as part of a diversified portfolio, it plays an important role.
Remember - investing is personal. Your goals, timeline, and risk tolerance should drive decisions. The FTSE 100 index works well for income seekers and conservative investors. Growth chasers might pair it with global tech exposure. Whatever path you choose, understanding this index gives you insight into UK markets and global finance.
