Should You Invest When the Market Is At An All Time High?

The market hits a new high, and suddenly everyone gets nervous.

Nobody says it that way when the market is down 20%. Then people say they are waiting for things to “settle down.” When the market is up, they say it feels too expensive.

This means the perfect time to invest is apparently never.

That is the weird thing about all time highs. They sound dangerous because they feel like a ceiling. The market has gone up, so it must be ready to fall.

Maybe it will.

That is always possible. Markets can and do drop when they are at all time highs. They can also drop when they are nowhere near all time highs. The market does not need your emotional permission to do either one.

The problem is that people treat “all time high” like it means something it usually does not.

They hear “record high” and translate it into “about to crash.”

History does not support this translation.

According to Dimensional, from 1926 through 2022, 30% of monthly S&P 500 closing levels were new market highs. After those highs, the average annualized returns were almost 14% 1 year later and more than 10% over the next 5 years. Those results were close to the market’s average returns over any period of the same length.

That does not mean stocks are safe over the next year.

It means all time highs are normal.

A market that grows over time has to hit new highs. Repeatedly. Otherwise, it would not be growing. We just get weird about it because “new high” sounds like “last high.”

Those are different things.

A new high can be followed by a correction. It can be followed by a crash. It can also be followed by another new high.

The headline tells you where the market is today. It does not tell you what your plan should be.

For someone in retirement, this is where the conversation needs to get more serious.

If you need money in the next 6 months, 12 months, or maybe even the next few years, that money probably should not be riding on the stock market anyway. Record high or not.

That is grocery money. Mortgage money. Tax money. Distribution money.

Putting that money in stocks and then acting shocked when stocks act like stocks is like buying a chainsaw and getting mad that it is bad at slicing tomatoes.

Wrong tool.

Short term money needs stability. Long term money needs growth. Mixing those up is where people get themselves in trouble. This is why whether now is a good time to invest depends first on when you need the money.

So, if you are 3 years from retirement, the question is not simply whether the market is too high. The better question is which dollars you actually need soon.

Some money may need to sit in cash or short term bonds. That gives you room to take withdrawals without being forced to sell stocks after a bad decline.

Other money may need to stay invested for the next 10, 20, or 30 years. That money still has a job to do. It has to fight inflation, replace a paycheck, and keep working long after you stop working.

Do not forget that.

Retirement does not turn you into a short term investor overnight. Yes, some of your money becomes short term. But unless you plan to die next Tuesday, a meaningful part of your portfolio still has a long time horizon.

That long term money is where "all time high" fear can get expensive.

You see the market at a record high. You wait.

Then the market goes higher. You wait again.

Then it finally drops, but maybe only back to a level higher than where you first got nervous.

Now you feel dumb buying after a drop that still leaves you worse off than if you had just followed the plan in the first place.

This is how “being careful” quietly turns into market timing.

And market timing rarely announces itself because nobody says, “I am going to make a poorly timed emotional decision today.”

They say something that sounds more prudent such as, “I just want to wait until things calm down.”

However, things rarely feel calm when the decision matters.

When markets are falling, people are scared. When markets are rising, people are suspicious. When markets are flat, people are bored and waiting for something to happen.

There is always a reason to hesitate.

That does not mean you blindly throw every dollar into stocks whenever you have it. That is not planning. That is just the other version of being reckless.

A good retirement plan separates the money by purpose.

Money for near term spending gets treated differently than money for long term growth. Tax planning matters. Withdrawal order matters. Cash reserves matter. Your pension, Social Security, Medicare, and spouse’s income all matter.

“All time high” is only one piece of the picture. Usually, it is not the biggest piece.

If the market being at a record high changes your entire plan, then the plan was probably too fragile to begin with.

The better approach is boring.

Know how much you need soon. Keep that money out of the blast zone. Keep long term money invested according to the job it has. Rebalance when your plan calls for it. Do not let a headline make a permanent decision for you.

Simple. But not easy.

All time highs feel scary because they make the future feel expensive. But the future usually looks expensive when you compare it to the past.

Houses used to cost less. Cars used to cost less. College used to cost less. A cup of coffee used to cost less. That does not mean the old price is coming back just because you remember it fondly.

The stock market works the same way often enough that waiting for the old price can become its own kind of risk.

So, when the market hits a new high, do not ask whether that high is good or bad.

Ask what each part of your money is supposed to do.

• Which dollars do you need soon?

• Which dollars need to grow?

• Which dollars would hurt the most if the market dropped right after you invested?

• And which dollars are you keeping on the sidelines because the headline scared you?

How you answer that makes a bigger difference than the market’s latest record.

If you are near retirement and trying to sort out cash reserves, withdrawals, taxes, and long term investing, this is the kind of work that belongs inside a real retirement planning process.
