How to evaluate investment risks: a 7-question check

Every investment can lose money. Here’s how to work out how much, how likely, and whether you could live with it.

The title of this post in black and gray on a white background.

TL;DR

  • Start with the worst case: how far has this kind of investment fallen before? The S&P 500 fell 57% in 2007–09, and bitcoin 77% in 2021–22.
  • Then match it to you: when you need the money, how much of your savings it is, and whether you could hold on through a fall like that.
  • Watch for borrowed money, things you can’t sell quickly, and anyone promising a guaranteed return.
  • LemonTrades tells you what moved your investments, and why, as it happens, so a big drop never comes out of nowhere.

Most people ask how much an investment could make. The better first question is how much it could lose, and what you’d do if it did.

The seven questions

  1. How far has it fallen before? Look up its worst drop, not its average year.
  2. When will I need this money? Money needed within a few years shouldn’t be in anything that can halve.
  3. How much of my savings is it? One stock or coin should be a small slice, so a collapse doesn’t sink you.
  4. Can I sell it quickly at a fair price? Property, private deals and small coins can be hard to sell in a panic.
  5. Is there borrowed money? Margin, leveraged funds and CFDs can lose more than you put in.
  6. Do I understand how it makes money? Profits, interest, rent, or only someone paying more later?
  7. Who is selling it, and how are they paid? Commissions and fees can push people toward worse products.

How far common investments have fallen

InvestmentWorst fallWhenBack to the old high
S&P 500About −57%2007 to 20092013
Nasdaq CompositeAbout −78%2000 to 20022015
GoldAbout −70%1980 to 19992008
Long-term Treasury bondsAbout −50%2020 to 2023Not yet
BitcoinAbout −77%2021 to 20222024
NvidiaAbout −66%2021 to 20222023

Approximate price falls from peak to low, before dividends and inflation. Even “safe” assets can drop a long way: long-term government bonds lost about half their value when interest rates jumped.

Red flags

  • A guaranteed or unusually high return with little risk.
  • Pressure to act now, or to keep it secret.
  • Payment in crypto, gift cards or a wire to a person.
  • A seller or adviser you can’t find on FINRA’s BrokerCheck or the SEC’s adviser database.
