Monthly Check Cadence
Monthly Check Cadence
A monthly check is the right frequency: often enough to catch errors, infrequent enough that you will not obsess.
Key takeaways
- Check your portfolio once per month, on a regular day (the 1st, or the 1st business day).
- The check takes 5 minutes: scan for errors, verify deposits and withdrawals, nothing else.
- A monthly check is frequent enough to catch fraud, missing dividends, or fee errors.
- It is infrequent enough that you will not be tempted to rebalance based on market noise.
- Monthly checking reduces anxiety for most investors—it replaces the urge to constantly log in.
Why monthly?
Checking more frequently (daily or weekly) correlates with poor performance. Investors who check daily tend to buy and sell more often, incurring higher costs and taxes. They also suffer from recency bias—the last week's market movement feels more important than it is.
Checking less frequently (quarterly or annually) risks missing errors. A fraudulent withdrawal, a missing dividend, or a fee error can compound over months. You want to catch these within weeks, not quarters.
Monthly is the Goldilocks frequency: often enough to keep you informed, infrequent enough to prevent obsession.
The 5-minute ritual
Set a calendar reminder for the 1st business day of each month. When the reminder fires, open your portfolio and perform this five-step check:
Step 1: Scan for obvious errors (1 minute). Log into your brokerage account. Look at the holdings list. Is there a position you did not buy? Is there a position missing that you know you own? Look for typos in fund names or sudden quantity changes.
Most brokerage interfaces highlight recent changes in color or have a "recent activity" view. Use these to skip the holdings that have not changed.
Step 2: Check for missed dividends or distributions (1 minute). Scroll to the "transactions" or "activity" section. Look for dividend payments or distributions from funds. Did the funds you own pay dividends this month? If you own a dividend-paying fund and you do not see a dividend in the past 6 weeks, the fund may not have distributed yet (funds typically distribute quarterly or annually) or there may be an issue.
In rare cases, a dividend is delayed due to a corporate action. But usually, if a dividend is missing, it just has not been paid yet.
Step 3: Verify deposits and withdrawals (1 minute). Scan the transactions for the past 30 days. Do you see the deposits you intended to make? Do the amounts match? If you made a withdrawal, does it match what you planned?
Step 4: Check for fees or unusual charges (1 minute). Look for any debit that is not a dividend or a planned contribution. Account maintenance fees, transaction fees, or advisory fees should be expected, but confirm they match what you agreed to. If you see a fee you do not recognize, click on it for details.
Step 5: Take a total value screenshot or note (1 minute). Look at the bottom of the brokerage page: what is your total account value? Write it down or take a screenshot and note the date. This becomes your monthly snapshot data (from the spreadsheet tracking article).
What to do if you find a problem
Missing deposit: Call or email the brokerage. Usually, deposits take 1–3 business days to clear. If it has been longer, the brokerage may not have received the transfer. Verify the transfer was sent from your bank.
Unexpected withdrawal: Call the brokerage immediately if you did not authorize it. This could be fraud (unlikely but possible) or a system error (more likely).
Missing dividend: If a fund usually pays dividends and you have not seen one, check the fund's recent distributions on the fund company's website (or Morningstar). If the dividend was paid to other holders but not you, contact the brokerage. If the dividend has not been paid yet, note the expected payment date and check again later.
Unexpected fee: Ask the brokerage for an explanation. Most fees are disclosed upfront, but errors happen. If you were charged incorrectly, you can usually get it reversed.
Wrong position: Confirm it is really there. Sometimes, a brokerage lists a position in a subsidiary or a related security that looks different but is actually the same holding. If it is truly wrong, contact the brokerage.
What NOT to do during the monthly check
Do not check performance. You will naturally glance at "gain/loss" or "return," and your eye will land on whether you are up or down this month. Ignore this number. It is noise. A monthly return of +2% or -2% tells you nothing about whether your strategy is working.
Do not rebalance. If your allocations are drifting, note it for the quarterly review. Do not rebalance in response to a monthly check. You will end up rebalancing too often, incurring unnecessary costs and taxes.
Do not check other accounts. If you have multiple accounts (Roth IRA, taxable brokerage, work 401k), check them separately, on different months if needed. Your monthly ritual is one account, one 5-minute review.
Do not open your aggregator or spreadsheet. This is a brokerage statement check. Get the facts from the source (your broker). Let the aggregator or spreadsheet do their monthly update later.
The emotional benefit
For many investors, a scheduled monthly check reduces anxiety. Instead of the constant urge to log in and see how you are doing, you have a designated time. When the urge to check hits, you can say, "I will know the answer in 3 weeks when I do my monthly review."
This ritual also creates accountability. You are making an explicit commitment to your portfolio. A written calendar reminder (or a digital notification) converts the vague notion of "monitoring" into a concrete weekly action.
Variations
Multi-account households: If you have accounts at multiple brokers (Schwab, Vanguard, Fidelity), you could check all of them on the same day, or stagger them throughout the month. Most people find it easier to do one monthly check that covers all accounts in 15 minutes.
Automated contributions: If you use automatic transfers (e.g., a monthly 401k contribution or an automatic rebalancing system), you can abbreviate the monthly check. You mostly just verify that the transfer cleared.
If you use an aggregator: You can log into your aggregator instead of multiple broker sites. The aggregator shows all accounts in one place. Just remember: aggregators sometimes lag by a few hours, and they can have sync errors. If something looks wrong, verify it against the actual broker statement.
When to skip a monthly check
If you are on vacation, sick, or just busy, skip the monthly check that month. The portfolio is fine without monthly monitoring. Do not try to catch up on back months—just do the next month's check when you get back to routine.
However, do not skip it for too long. After 3 months without a check, do a check. It takes 5 minutes, and it ensures you have not missed anything serious.
How it flows
Next
A monthly check catches errors and keeps you informed. But a once-per-month glance is not enough to assess your strategy. That requires a deeper review: looking at allocation drift, considering rebalancing, and checking whether you are on track to your goals. That is the quarterly review, coming next.
