Who actually trades? Market participants

You can name the main groups of market participants and explain how their goals shape price moves.

Who is on the other side

Every time you buy, someone sells to you. Every time you sell, someone buys. Behind each price on a chart are real people and institutions with very different goals, budgets and time horizons.

Some are like you, trading their own money from a phone. Others manage billions for millions of savers. Knowing who they are helps you understand why prices move the way they do, and why the market does not care about your plan.

The main players

Retail traders trade their own money in relatively small amounts, usually through an online broker. If you are reading this, you are probably one of them.
Institutional investors manage money on behalf of others: pension funds, insurance companies, mutual fund and ETF providers. They trade large sizes, often with long horizons, and their buying or selling can push prices for days or weeks.
Hedge funds are private funds, generally limited to wealthy individuals and institutions. They can use strategies such as borrowing to increase their positions and short selling, which magnify both gains and losses. Some trade very actively.
Market makers are firms that stand ready to buy and sell at publicly quoted prices. Because they always show a price on both sides, everyone else can trade more easily. They earn from the small gap between the two prices.
Banks and brokers route orders, trade for clients and for themselves, and are the main dealers in markets such as currencies and many bonds.
Companies use markets for their business. An airline may lock in its fuel costs, an exporter may protect itself against currency moves, and a firm may buy back its own shares.
Central banks set short-term interest rates and steer the money supply. Some also buy or sell bonds or currencies. One decision can move entire markets.

None of these groups is the enemy. But most of them have more information, more capital or more time than a single retail trader, and none of them is trying to help you.

One candle, many reasons

Imagine a fictional stock falls 3% one afternoon. On the chart it is one red candle. Behind it, very different things may be happening at the same time:

A pension fund is selling a large position slowly, over several days, to bring its portfolio back to its target mix.
A hedge fund is selling because its model has turned negative on the sector.
Market makers are buying from sellers and selling to buyers all afternoon, keeping a price on both sides.
Hundreds of retail traders sell because the drop scared them, and a few buy because it looks cheap.

None of them coordinated with the others. The candle is simply the sum of their decisions. That is why one candle rarely has one reason, and why stories that explain every move after the fact deserve some caution.

Common mistakes

"They are manipulating every move." Most moves are many participants acting at once, not a plot. Real manipulation, such as pump-and-dump schemes, does exist, and it is illegal.
"Big players always win." Institutions make losing trades too. They have different constraints, not a free pass.
"The market maker is trading against me personally." Market makers quote prices to everyone and manage their own risk. They do not see or care about your plan.
"Central bank decisions only matter to economists." A single rate decision can move stocks, bonds and currencies within minutes.
Copying what big players seem to be doing. By the time a large trade shows up in the news or on a chart, it is often already finished. You only see its traces.

The takeaway

Every price is the meeting point of very different players. Know who they are, and you stop taking every move personally.

Quick quiz

4 questions. Instant feedback, nothing is saved.

1Tap the group that sets short-term interest rates and can move entire markets with one decision.

Tap the chart.

Central banks set short-term interest rates and steer the money supply. Their decisions can move stocks, bonds and currencies at once.
2What does a market maker do?

A market maker quotes a price to buy and a price to sell, which makes trading easier for everyone. It earns the small gap between the two.
3A pension fund buys shares with its members' retirement savings. Which group is it?

Pension funds, insurers and fund providers invest large sums on behalf of others. That makes them institutional investors.
4A stock drops 3% in one afternoon. What is the most realistic explanation?

A price move is the sum of many independent decisions. Single-cause stories usually come after the fact.
