Whenever people talk about investing, the terms risk and reward tend to come up a lot, and they usually tend to come up together.발음듣기
대기중
Somehow implying that the more risk you take, the more reward that you might be able to get.발음듣기
대기중
But what I want to do in this video is give a little bit of an introduction to that, or a little bit of context, and a little bit more structure on how do you think about risk and reward.발음듣기
대기중
So let's say that we have $1,000, and we want to figure out what we can do with this $1,000.발음듣기
대기중
And in this situation, our reward - I'll start with the reward first - is we'll get - I don't know - 1% in interest per year, 1% annual interest.발음듣기
대기중
Well, if I'm putting it into a savings account - and I'm assuming I'm putting it into an FDIC insured savings account.발음듣기
대기중
Which means that if for whatever reason that bank were to fail, below some limit, the Fed will insure your money.발음듣기
대기중
So even if this bank fails, and it loses all of its money and everything, you'll still get your deposit back.발음듣기
대기중
So if you're investing, or if you're putting money in an FDIC insured savings account, your risk is essentially 0.발음듣기
대기중
But you might say, look, you know, this is a good risk, but I feel like I can get more than 1% on my money, let me think about the other places that I could invest it.발음듣기
대기중
Well, you could - and obviously I'm not going to be exhaustive on all of the different investment options, I just want to give you a sense of risk and reward.발음듣기
대기중
There's really very few circumstances in which you could imagine that this company would not be able to pay off its debt.발음듣기
대기중
So the reward here, if you lend your money to this company, they will pay you 6% in annual interest on your $1,000.발음듣기
대기중
The Federal Reserve isn't saying that they'll either give the money if the bank goes out of business, or they'll print the money if they don't even have it.발음듣기
대기중
If it goes bankrupt, then all the people that the company owes money to will go after that company's assets.발음듣기
대기중
But maybe you are low on the pecking order, or maybe the company doesn't have enough assets to pay everyone back.발음듣기
대기중
But since this is a very reputable company, and as we said it has a lot of assets, it has a very stable business, it does good in boom times and in recessions, this is a low risk of business default.발음듣기
대기중
So I'll write, low risk, right over here, because we're assuming it is a reputable company that has a lot of assets, and all the rest.발음듣기
대기중
Now let's say that even that 6%, you know, it's all right, but you feel like you could get more.발음듣기
대기중
So let's say that you have a friend who is a - let's say that he's just starting his career as a doctor, so he says he has a nice, stable job.발음듣기
대기중
So he's just starting, and he wants to find people who can help him with the down payment on the house.발음듣기
대기중
And he says, anyone who's willing to lend to me, I will give them 8% annual interest on their money.발음듣기
대기중
Maybe he has of some type of addictive personality, and he likes to drink away all of his money.발음듣기
대기중
But it's definitely riskier than this company, because you have no assets to go after if he doesn't pay.발음듣기
대기중
But there are definitely more risks associated with this individual doctor who does not have assets you can go after.발음듣기
대기중
And you're just going to invest in a bunch of - a broad portfolio, kind of investing in the market as a whole.발음듣기
대기중
So you look at historical results in the market and you say, look it, goes up and down every year.발음듣기
대기중
But over long periods of time, it looks like people - and this isn't the exact number - but it looks like people have averaged approximately 10% per year.발음듣기
대기중
Well, the risk is that this expectation is just based on what the historical returns in the market were.발음듣기
대기중
There are huge periods of time in the market - I'm talking 10, 20, 30 years where the market is flat.발음듣기
대기중
In any given year, the market could go down in the double digits or in the 30 , 40% even, in a really, really bad year.발음듣기
대기중
It's not going to be a constant upward trend, like your savings account will be. Volatility.발음듣기
대기중
Your brother-in-law has been out of work for a little bit, and he says that all he needs to start his new guaranteed money making scheme is $1,000, so he can buy the equipment, so that he can start it up in his garage.발음듣기
대기중
And, let's say that your brother-in-law is right, and this becomes a million dollar business.발음듣기
대기중
So this is a very, very, very, very high reward, if what your brother-in-law is telling you is correct.발음듣기
대기중
Well, the risk here is obviously that he's not correct and that he squanders all of your money.발음듣기
대기중
And not only could you lose the monetary money that you put in, it could also ruin your relationship with your brother-in-law and maybe your spouse.발음듣기
대기중
Once your brother-in-law loses all of your money, it won't be so easy at Thanksgiving anymore to have a civil conversation.발음듣기
대기중
So in general, the overlying - I probably did more of these scenarios than I needed to - but I think you see the general trend.발음듣기
대기중
And if there's something that looks like it's really safe with the really high reward, one of those two things are probably not true.발음듣기
대기중
So if we were to plot all of these, and I haven't really quantified - I haven't given you a way of measuring risk.발음듣기
대기중
In future videos we can think about that, and academics have thought about ways of measuring risk.발음듣기
대기중
If you lend to the doctor, once again, the risk is a little bit higher than lending to that company or the savings account.발음듣기
대기중
Your brother-in-law, super high risk, probably off the charts over here, but also super high reward.발음듣기
대기중
