What is "cash"? A safer and more secure option

Cash investments can lower the overall risk of your portfolio and give you a place to hold money while you wait to invest it.


  • Cash investments are a place to keep money safer from market risk.
  • Your choice between money markets and CDs depends on factors like whether you need to lock in a certain yield and whether you prefer to be covered by FDIC insurance.

Why invest in cash?

Cash investments are very short-term investments. While intended to be stable, they aren't quite as safe as a bank account. So why bother with them? If you have money you need to keep accessible—because you plan to spend it soon or because you're holding onto it while you research other investments—you can often earn a little more interest than you'd get in a bank account.

But making money isn't the goal. They're meant to They're meant to provide a relatively low-risk investment option for money you already have.

What is a money market?

These securities have ultra-short-term maturities (from a few days to 1 year) and are considered lower-risk investments. Their share prices are intended to be stable, although the interest rates they pay will fluctuate (and the stability of the share price isn't guaranteed).

Money markets are also extremely liquid. You can invest in them through a mutual fund.

What is a CD?

Certificates of deposit (CDs) are promissory notes issued by banks. As such, they're insured up to a certain amount by the Federal Deposit Insurance Corporation (FDIC) and considered completely safe if held until maturity.

Like bonds, CDs have a specified interest rate and maturity date (usually 5 years or less).

If you buy a CD through a bank, you'll pay an interest penalty if you need your principal back before the maturity date. If you buy a CD through a brokerage, the value of the CD will fluctuate but there's no penalty for selling the CD on the secondary market before maturity.
