In this lesson you will
Sort your money goals by when you will need the money, and understand why that date changes how much price movement you can accept.
The idea in plain language
FactThe SEC's investor education site defines risk as “the degree of uncertainty and/or potential financial loss inherent in an investment decision,” and notes that all investments involve some degree of risk.
Two ideas from the same source shape almost every investing decision:
- Time horizon is how many months, years, or decades you plan to invest before you need the money for a goal.
- Risk tolerance is your ability and willingness to lose some or all of your original investment in exchange for potentially greater returns.
Money you need soon has little time to recover from a drop. Money you will not touch for decades can ride through more ups and downs, though time does not guarantee a recovery. Cash has risks too: inflation reduces what a fixed amount can buy.
Worked example
IllustrationSame drop, different goals
Alex has $3,000 for a car repair fund needed in nine months, and separate retirement savings that will not be touched for decades. Suppose both fell 20 percent in a bad month.
- The repair fund drops to $2,400. Alex is $600 short on a date that will not move.
- The retirement savings have years before they are needed, so there is more time for prices to change again. Not a promise, just more time.
| Loss | Gain needed to recover |
|---|---|
| 10% | 11.1% |
| 20% | 25.0% |
| 30% | 42.9% |
| 50% | 100.0% |
Losses and gains are not symmetric. A 50 percent loss needs a 100 percent gain just to return to where you started.
Try it: sort your goals by date
Fill in one row per goal. Then group them: within 1 year, 1 to 5 years, more than 5 years.
| Goal | Amount | Date needed | Months away | Group |
|---|---|---|---|---|
For each group, write one sentence answering: “If this money fell 20 percent right before I needed it, what would I do?”
