Mutual Funds: A mutual fund is a pool of money and resources from multiple individuals (often vast numbers of people, actually) being put together and managed as a group by investment specialists. The primary appeal of these is that the money is professionally managed, but not personally so; it gives smaller investors access to professional money managers that they would not have access to on their own, at cheaper rates than if they tried to hire one for just their own assets. The secondary appeal is that, due to the sheer number of people, and thus capital, that is being invested at once, the money can be invested in a wide variety of industries, and is generally more stable than investing in just one company or industry. Low risk, low reward, but overall at least mostly reliable. Retirement plans are often invested in mutual funds by employer choice, through companies like Fidelity or John Hancock.

Hedge Funds: A hedge fund is a high risk, high reward mutual fund. Investors are generally wealthy, and have the room and safety to lose large amounts of money on an investment that has no promise of success, especially since money cannot be withdrawn at will, but must remain in the fund for a period of time following investment. It gets its name from "hedging your bets," as part of the strategy is to invest in the opposition of the fund's focus in order to ensure that there is a backup plan to salvage at least some money if the main plan backfires. Other strategies are also on the riskier side, often planning to take advantage of ongoing events like buyouts, mergers, incumbent bankruptcy, and shorting stocks (that's the one that caused the gamestop incident).

Private Equity: Private equity is... a nightmare that got its own incredibly good Hasan Minhaj episode of Patriot Act, so if you've got 20 minutes, an interest in comedically-delivered, easily-digestible, Real Information, and an internet connection, take a watch of that one. (If it's not available on YouTube in your country, it's originally from Netflix, or you can probably access it by VPN.) Private equity companies are effectively hedge funds that purchase entire companies, rebuild them in one way or another, and then sell them at (hopefully) a profit. Very often, the companies purchased by private equity are very negatively impacted, especially if the private equity group is a Vulture Fund. Sometimes, it's by taking it apart to sell off; sometimes it's by just bleeding it for cash until there's nothing left. Sometimes, it's taking over a hospital and overcharging the patients while also abusing the staff! (Glaucomflecken has a lot of videos on the topic of private equity in the medical industry, check him out.)

Venture Capital: In contrast to private equity, which purchases more mature companies, venture capital is focused on startups, or small businesses that have growth potential. These are the kinds of hedge funds that are like a whole group that you'd see some random tv character calling an Angel Investor (they're not actually the same thing, but they overlap by a lot). I'd hesitantly call these less ethically dubious than private equity, but I'm still suspicious.

And finally, to answer your question on what ETFs are and how they fit into the above.

Exchange Traded Funds: ETFs are... sort of like a mutual fund. Sort of. You are, to some extent, pooling your money... ish.

An ETF is like a stock that is made out of partial stocks. So instead of paying $100 for stock A, and not getting stocks B/C/D that all cost the same, you buy $100 of the ETF, which is $25 each of stocks A/B/C/D. You are getting a quarter of a unit of stock, which isn't normally an option, but because you are purchasing through an ETF that officially already bought those Whole stocks, you can now purchase the partial stocks through them.

They buy the whole stocks, then they resell you mixes of those stocks. They still officially own the whole stocks themselves, but you now own parts of the stocks. Basically, you own "stock" in a company that owns stock in other companies, and in that process you own partial stocks in those other companies.

I'm going to re-explain this using fruit.

Imagine you can buy apples, oranges, melons, grapes, etc. You can also buy fruit cups. You can only buy the individual fruits in big batches or you can pool your money with a few other people, hand it to a chef. The chef will decide which fruits look like they'll taste the best by lunch time, buy a bunch of those fruit pallets with your combined money, and plan out the best possible fruit salad for you to share with a bunch of people once lunch rolls around.

You could also buy a fruit cup. You don't have a lot of control over what's already in the fruit cup, but there are a few different mixes available--that one has strawberries, but that one over there uses kiwi, and the other one that way has pineapple--and you can pick which mix you want. It's a pretty small fruit cup, and it's predesigned, but you can choose the one you want without having to pool money with everyone else. You just first have to let someone else design the fruit cups you choose from, and you don't know which ones are probably going to survive the best to lunch time unless you ask a chef (which defeats the purpose of buying a fruit cup instead of pooling your money, and asking the chef costs money).

That's the ETF. The ETF is the fruit cup.

The upside is that you can now just track the prices of your fruit cup, instead of tracking the prices of four different fruits, and so if the price of one fruit drops, you can just... let the other three buoy it.

Of course, in the real world, there are more than just four stocks involved in an ETF. This part of the Investopedia article lists a few examples, and they're usually themed and involve anywhere from 30 (DOW Jones) to thousands (Russell) of shares by stock type, or by commodity/industry. So with the ETF, you can invest in an entire industry, like technology, and just keep track of that single "stock" in the industry game.

They do cost less in brokerage/management fees than regular mutual funds, and they have a slightly lower liquidity (slower to cash out). There also exist actively managed ETFs, which are basically mutual funds for ETFs. You are paying the chef to buy you premade fruit cups.
