Donât Check Your P&L More Often than Once a Month
When you check your brokerage statement, how does it make you feel?
If itâs up since the last time you looked, it probably feels pretty good.
If itâs down, it makes you feel bad.
People donât like to feel bad. So if the market has been going down for a while and they think theyâre losing money, theyâll stop checking it.
If the market has been going up for a while, theyâll check it every day. In fact, most people will check it multiple times a day.
For all the spreadsheet jockeys out there, you know that if you press the âF9â key then it recalculates the spreadsheet.
When I was a trader, I noticed that I pressed F9 a lot more on good days than on bad days. On terrible days I would absolutely dread pressing the F9 key. On great days I was pressing it three times a second.
Over time, I began to think of this as The F9 Problem.
On one hand, pressing it every second gives you more information, but isnât necessarily a good thing. More information can lead to worse decisions. That is an argument for checking it less often.
But on the other hand, sometimes you need to know how bad the damage is so you can take action. You canât stick your head in the sand because most problems donât get better if you ignore them.
If you do this, you are no better than the investor who leaves his monthly statements on the counter unopened.
What is the answer?
The Sweet Spot
Michael Batnick, director of research at Ritholtz Wealth Management, published an important finding a few weeks ago on Twitter.
He noted that if a hypothetical investor were to check his P&L on a daily basis, there would be a 46% chance that he would show a loss.
But if he were to check his P&L once a year, there would only be a 26% chance that he would show a loss. (Because markets go up over time.)
The goal here is to stay invested and continue compounding. And if you are regularly seeing losses, you are more likely to get frustrated and liquidate your investmentâand stop compounding. Which would be catastrophic.
Like I said, this is an important finding. It argues strongly for looking at your P&L less often.
But thereâs a sweet spot. If you look at it too infrequently, you may miss an opportunity to change your asset allocation.
Most investors shouldnât try to time the market, but I do think that there are one, maybe two times in your investing career that might argue for a sizable shift in your investment mix.
My answer? Something in the middle, which is about what I do.
Donât turn off paper statements! Get them delivered to your house, and when they come, open them. But donât log onto the website.
Once a month should balance the competing concerns of having too much negative feedback, versus willful ignorance. Before the internet, people did just fine with monthly statements.
The Merits of Illiquidity
There are bigger implications of the F9 problem.
Everyone loves private equity (and venture capital) nowadays. I will tell you the reason everyone loves private equity.
Because it locks up your money for 10 years!
Imagine you could log onto a website and watch your private equity fund tick second by second, like a stock. Imagine it gave you quarterly liquidity.
You would be out of it in a second. But you literally canât get your money back for 10 years, so you donât worry about it. There arenât too many 10-year periods in history where the stock market shows a loss, so you are probably going to be happy at the end.
Thatâs it! Thatâs the only advantage.
You canât F9 your private equity investment. Unlike a hedge fund, which offers quarterly liquidity.
I personally donât think a lockup of three, five, or 10 years on a hedge fund is unreasonable. A hedge fund manager is free to take different risks if they donât have to constantly worry about getting their assets yanked.
The takeaway here is that you should not be afraid of illiquid investments. Fear the valuations, not the illiquidityâespecially if you are pretty sure you are not going to need the money.
Being a capital markets guy by trade, I have always been leery of situations in which it is difficult to get my money out, but I am getting used to the idea. (I used to brag that I could be out of my entire portfolio in 5 minutes.)
It is hard to F9 your rental house, or your gas station, or your laundromat. If you hold it for 10 years, there is a pretty good chance you are going to make money on it.
Of course, the ultimate illiquid investment is your retirement account, for which you must pay an early withdrawal penalty.
Itâs no surprise people donât dwell on the daily performance of their retirement accounts. And for heavenâs sake, donât get yourself in a position where you might have to withdraw from it and pay the penalty.
Donât check your account every day. Check it every month. But make sure you check it, no matter what surprises you think may await you.
