5 Mistakes I Made in My First Year of Investing on PSX

The stuff nobody tells you before you open a brokerage account — checking prices ten times a day, chasing tips from group chats, and other things that quietly cost me money in my first year on PSX.

5 Mistakes I Made in My First Year of Investing on PSX
I opened my brokerage account almost by accident. A friend was doing it, said it took twenty minutes, and I figured I'd put in some money I wasn't using anyway. That was a few years ago now. Looking back, I made almost every beginner mistake in the book, and most of them had nothing to do with picking the "wrong" stock. Here's what actually cost me.
1. I checked the price ten times a day
For the first few months, PSX prices were basically a second phone lock screen for me. Market opens, I check. Lunch break, I check. Before bed, I check one more time just in case. It did nothing except make every red day feel like a personal disaster and every green day feel like I was a genius. Neither was true. I wasn't trading on any of that information — I was just watching numbers move and reacting emotionally to them.
The stocks I actually made money on were the ones I checked the least. The ones I stared at constantly, I ended up selling out of pure anxiety, usually right before they recovered.
2. I bought stocks because a WhatsApp group said to
Every investing group chat has that one guy. Confident, always has a "tip," always talking about some cement or sugar stock that's "about to move." I bought into two of these tips in my first six months. Both times I had no idea why the stock was supposedly about to move, what the company actually did beyond the name, or what their last quarterly results looked like. I just trusted the guy.
One of the two worked out fine, honestly, more by luck than anything. The other one I held for eight months waiting for a "move" that never came, and eventually sold at a loss out of boredom. The lesson wasn't "don't listen to tips" — it was that I should never buy something I couldn't explain to another person in two sentences.
3. I ignored dividends completely
For a while I was purely focused on share price going up. Buy low, watch it climb, sell high — that was the whole plan in my head. It took embarrassingly long for me to actually pay attention to dividend-paying stocks and realize some of my holdings were quietly paying out cash every year regardless of what the share price was doing on any given week. A couple of the more boring, unglamorous stocks in my portfolio — the ones I almost sold out of impatience — turned out to be the ones giving me the most consistent return once you counted dividends in.
4. I never actually tracked my overall portfolio
This one's almost funny in hindsight given what I do now. For over a year, I genuinely did not know my total return across everything I owned. I knew roughly how individual stocks were doing because the app showed me green or red next to each one, but nobody was adding it all up for me — gains here, losses there, dividends I'd half-forgotten about. I was investing without actually knowing if I was ahead or behind.
It sounds basic, but this was honestly the biggest one. You can make every other decision right and still have no idea whether you're winning, simply because you never sat down and looked at the full picture.
5. I panic-sold during a dip that reversed a week later
There was a stretch where the market had a rough couple of weeks — nothing unusual in hindsight, PSX has these periods regularly — and I sold two positions out of pure nerves. Both recovered within about ten days. I'd locked in real losses on paper money that would have been fine if I'd just left it alone. What made it worse was that I hadn't set any actual plan beforehand for what I'd do in a downturn. I was making the decision in the moment, scared, which is exactly the wrong time to be making it.
What I'd tell my first-year self
Check less often. Understand what you own well enough to explain it simply. Pay attention to dividends, not just price movement. And keep an actual running total of how your money is doing across everything — not stock by stock in your head, but the real number.
That last one is honestly why we built the portfolio tracking on PortfolioPK the way we did — one view of everything you hold, updated as prices move, so you're not doing the math in your head at 11pm wondering if this year was actually a good one.
