Cramer considers stocks and bonds to be in two separate categories. Stocks are a tool to make money, and bonds are for capital preservation — for protecting money and providing a small, steady return that can offset the impact of inflation.
"Depending on how old you are, there is a huge difference in how you should approach the very idea of putting your money in bonds," Cramer said. (Tweet This)
In Cramer's perspective, many financial experts tell their clients to own more bonds a lot earlier in their lifetime than what is really necessary. An investor likely will not get rich from owning Treasury bonds. So, for those investors under 35 who own a bunch of bonds with the idea that they will slowly make money, Cramer thinks they're being too cautious.
Even in a 401(k) and an IRA, Cramer recommends that younger investors weigh their investments very heavily toward stocks, particularly because these types of accounts will allow investors to avoid capital gains or dividend taxes. That means gains can compound tax-free year after year.
However, as investors grow older, owning Treasury bonds becomes absolutely essential because bonds are simply safer. So, once investors have used the stock market to make themselves financially independent, they should put more money into U.S. Treasuries for protection.
How much of a retirement portfolio should be kept in bonds versus stocks? Cramer broke it down by age:
- 20s: None
- 30s: 10 percent of your retirement fund; 20 percent if you are conservative
- 40s: 20 to 30 percent
- 50s: 30 to 40 percent
- 60s: 40 to 50 percent bonds
- Post-retirement: Increase bond exposure to 60 to 70 percent
"You're going to be living off your investments for the rest of your life, so some part of your portfolio should always be trying to create more wealth in case you live longer than you expect and need more money to support yourself," Cramer said.
So, for younger investors, Cramer says putting money into bonds is a "fool's game." But as one grows older, that bond exposure should grow. This will ensure the wealth generated from stocks is protected against the volatility of the stock market.
