Buy and Hold Investing: How It Works and How to Stick With It

What is buy and hold investing?

Buy and hold means choosing investments you plan to keep for many years. You don't try to profit from short-term ups and downs. It can make investing simpler and cheaper, because you trade less.

But buy and hold does not make returns smooth. A weak company can stay weak for years, and even a well-spread portfolio can fall a lot. You still need to check what you own from time to time.

The hard part is rarely the buying. It is holding on when prices fall and every headline says "sell".

Why does the plan come before the purchase?

First decide when you will need the money and how big a fall you could live with. Savings for retirement in 30 years can wait out a bad year. A home deposit needed in two years cannot.

To hold through a fall, you need two things. You need the nerve to watch your balance drop. And you need enough cash elsewhere, so you are never forced to sell. The SEC, the US markets regulator, has a guide to asset allocation that links these choices to your time and your comfort with risk.

What is worth holding for years?

Time alone cannot fix a weak investment. For a company, examine the business, debt, cash and competition. For a fund, check its goal, holdings, fees and concentration.

A broad fund spreads your money, but it can still lean on one country, one industry or a few giant companies. Owning several funds that hold the same companies adds work without much extra safety. See how to diversify.

So when should a buy-and-hold investor sell? Good reasons include:

• you have reached your goal and need the money
• your plans or your time frame have changed
• a fund has changed its strategy
• real news breaks the reason you bought

A falling price alone is a reason to look closer. It does not prove you should sell, or buy more.

How does compounding work when returns jump around?

Compounding means you earn returns on your earlier returns, not just on the money you put in. Suppose $1,000 grows by a steady 5% a year, with no fees or taxes. It becomes $1,050, then $1,102.50, then $1,157.63.

Real share returns are never steady. A 20% gain followed by a 20% loss does not bring you back to the start. $1,000 rises to $1,200 and then falls to $960.

The average of +20% and −20% is zero, but you lost 4%. So don't judge results by averaging percentages. The order of good and bad years also matters when you add or take out money.

Should you invest the same amount every month?

A common habit is to add a fixed amount on a schedule. With $50 each time, you get 2 shares when a made-up share costs $25, and 1 share when it costs $50. You automatically buy more when prices are low. This makes the habit easier, but it does not promise a profit.

You may already have a lump sum, a large amount to invest at once. Spreading it out means some money waits in cash for longer. That can feel calmer, but it is a choice with its own costs.

Fees keep running while you hold. A 0.2% yearly fee on $10,000 is about $20 a year, and a 1% fee is about $100. Over 20 years the gap grows much bigger.

Read the fund's documents and the SEC's guide to fund fees. The ETF vs mutual fund cost guide shows how to compare them.

How often should you check your investments?

Set a review date, such as every six months. Decide in advance what would make you act: one of the selling reasons above, or a big drift in your mix. A busy news day is not on the list.

Rebalancing brings your mix back to plan. Say you aim for 60% shares and 40% bonds on $10,000, but you now hold $7,000 in shares and $3,000 in bonds. That is 70/30. Moving $1,000 from shares to bonds restores 60/40, before costs and tax. New money can do the same job.
