I Check My Portfolio at 4 AM. If It's Up, I Stare. If It's Down, I Close the App

4 AM. The Only Light Is My Phone Screen

The house is dark. Everyone’s asleep. The only light comes from my phone screen.

It’s 4 AM. Ever since I started going to bed at 10 PM with my daughter, I naturally wake up at this hour. It’s been about four or five years now. My body just wakes up before the alarm.

The first thing I do is check the Dow and S&P 500. Still in bed, I open my phone and see how New York closed the night before. My index funds track these two indices almost perfectly, so by looking at them, I already know roughly what my portfolio looks like.

Here’s the thing — the real heart-pounding moment isn’t when I open my brokerage account. It’s when I check the Dow and S&P 500. Because at that point, the outcome is basically decided. If I see +2%, I think “nice.” If I see -1.5%, my stomach tightens. And I’m still in bed.

Opening the Account at 5 AM

After checking the Dow and S&P 500, I open my actual brokerage account around 5 AM.

Honestly, the feeling is closer to “scared but I have to look” than excitement. I rarely open it with a sense of anticipation. More often, I brace myself — “okay, how bad is it today?” Strangely, no matter how many years I’ve been investing, this feeling never goes away.

But since I’ve already checked the indices, the result is almost always what I expected. The only wildcard is the exchange rate. If the yen weakened overnight, my portfolio looks better than expected. If it strengthened, the opposite. When you’re invested in US index funds from Japan, the yen-dollar exchange rate is the only real surprise each morning.

If It’s Up, I Stare for Five Minutes

When I open the account and it’s up?

I stare at the numbers. How much unrealized gain do I have? How much did it go up from yesterday? I just look at it. For about five minutes. I’m not analyzing anything. I’m just soaking in the good feeling of watching a number get bigger.

My secret 4 AM grinning session, invisible to everyone.

Some people might call this a waste of time, but it’s important to me. Because I literally can’t tell anyone. “Hey, my unrealized gains went up 300,000 yen yesterday” — you can’t say that to your coworkers or friends.

I once had a boss who constantly bragged about money. The reactions from people around him were predictable: “Then buy us dinner” or “Must be nice having no pressure at work.” The moment you talk about money, relationships are at risk. So I say nothing.

Instead, I grin at my phone screen alone at 4 AM.

If It’s Down, I Close the App Immediately

When it’s down?

The viewing time is extremely short. “Eh, that’s how it is today.” Close the app. Pretend I didn’t see it.

I couldn’t do this before. When I was sitting on unrealized losses, the negative numbers would haunt me all day. This constant background noise of “I’m in the red again today.”

But things are different now. After eight years of steady investing, I have a substantial cushion of unrealized gains. Even if it drops, the overall position is still well in the green. So a daily dip is just “today wasn’t great.” By the next morning, I’ve already forgotten.

Short-term trading was a completely different beast. When I was trading individual stocks, every loss felt personal because I made the call. “I should have sold then.” “Why did I buy more?” I’d beat myself up over my own decisions. Not just for a day — for days. I once lost ¥2 million on a single stock and couldn’t stop checking the price obsessively — that version of “checking” was nothing like what I do now.

With index investing, my judgment isn’t part of the equation. When the numbers go down, it’s just “the whole market is down.” The emotional damage is dramatically smaller. The reason my morning portfolio check doesn’t wreck my mental health is probably because of this structure.

Living in a World Where 1 Million Yen Moves in a Day

As your portfolio grows, daily swings become absurd.

I’ve had mornings where it went up nearly 1 million yen (~$7,000) overnight. That genuinely freaked me out. More than my monthly salary, generated while I was sleeping. No matter how many times it happens, I can’t get used to it. The feeling is less “happy” and more “is this okay?”

On the flip side, there are days when it drops by hundreds of thousands of yen. But oddly, the impact doesn’t hit as hard as the gains. Loss aversion theory says losses should hurt more, but I think the cushion of unrealized gains lets me rationalize: “I’m still way up overall.”

This experience of “daily portfolio swings exceeding my monthly salary” has loosened my grip on income obsession. Same reason I stopped caring about colleagues getting promoted. The salary gap between me and a department head? That’s a rounding error compared to how much my portfolio moves on any given Tuesday.

The Morning I Crossed 30 Million Yen

The most memorable morning check was when my assets crossed 30 million yen (about $200,000).

Why 30 million? Because it was roughly equal to my remaining mortgage balance.

Having assets exceed the mortgage meant something deeply personal to me. The loan was still there — monthly payments continued as usual. But psychologically, I felt like the house was mine. Worst case, assets cover the debt. The house stays. That feeling was worth more than the number itself.

That morning, I told my wife.

“We crossed 30 million.”

Her response: “Oh nice, that’s great!” She was happy because I was happy. Not so much about the number itself, but because she saw me genuinely excited. That made it even better.

I remember crossing 50 million too. But the 30 million morning hit harder. Having a clear goal — surpass the mortgage — made the achievement feel concrete. Reaching 50 million was nice, but it immediately became “okay, next is 60 million, then…” A checkpoint in an endless marathon.

And now 60 million is the current target. I catch myself constantly calculating how long it’ll take to get there. I’ll probably be chasing the next number for the rest of my life. But honestly, I don’t mind. As long as there’s a morning where I get to open my account and think “how’s it looking today?”, the marathon doesn’t feel like suffering.

My Family Has No Idea

My wife and daughter don’t know about this morning routine.

They probably think I’m playing games or doing whatever during my alone time. Not once has anyone asked what I’m doing at 4 AM.

I’m not hiding it. If asked, I’d tell them. But nobody asks, and there’s no reason to volunteer it. “I check my brokerage account on my phone at 4 AM” — that conversation would end with a “huh, okay.”

But when I think about it, this state of “nobody knowing” might be the essence of my investing style. Nothing flashy. Tell no one. Check the numbers alone at 4 AM. Grin if they’re up. Close the app if they’re down. Repeat.

Five Morning Minutes That Anchor the Day

One practical benefit: checking my portfolio in the morning means I don’t think about it during the day.

Sneaking peeks at my brokerage account during work would be terrible. Imagine sitting in a client meeting while mentally calculating unrealized losses. But by getting the lay of the land in the morning, I can coast through the workday thinking “it was fine as of this morning.” Five minutes of morning checking buys me an entire day of mental calm.

What would I do with this 4 AM time if I weren’t investing? Probably waste it. In fact, I used this early morning window to study for and earn my FP (Financial Planner) certification. Once my mornings became about “doing something that builds my own assets,” getting up early stopped feeling like a chore. Going to bed at 10 PM with my daughter is partly for her, and partly to secure this morning time for myself. Without a kid, I’d probably stay up late and sleep in.

At the end of the day, if someone asked me what I actually do as an investor, the answer would be: “I check my portfolio at 4 AM.” I haven’t made a single trade. I haven’t sold a single index fund since 2018. This is literally all I do. Check the numbers every morning. Stare for five minutes if they’re up. Close the app if they’re down. That’s it.

I didn’t think something this boring could fill an entire article, but here we are. Probably because this quiet morning ritual contains every emotion I have as an investor. Joy, anxiety, loneliness, accomplishment. It’s all there, on a phone screen at 4 AM.

Tomorrow morning, I’ll wake up at 4 again. Check the Dow. Check the S&P 500. Open my account at 5. Grin for five minutes if it’s up. Close the app if it’s down. I’ll probably still be doing this ten years from now.
