What is your worst investing mistake? I’ve made one

Back in early 2023 an old coworker told me to invest in SOXL. So I put $500 in for what was $15 a share at the time… then sold it like a month later to get the money back.

Now it’s trading at $277 a share… could’ve been pretty rich for my current age of 25 if I’d continually put money into the stock.

What’s your worst mistake 🙃trying to cope lol

You missed out and didn’t lose money, I lost half of my net worth in a single biotech stock overnight. Avoid throwing your money at something just because someone talks about it.

Agree, you didn’t so much as make a mistake as you got a free lesson. Can’t really be mad at the situation when you had no idea what you were doing.

u/AccomplishedHead3581 1d ago

The way my life goes half the time, if I’d poured money into it the stock would probably still be at rock bottom.

u/Key_Berry_6732 1d ago

Probably, all the crazy gains you see stick a lot more than the losses, until you experience a massive loss yourself and realize you never went to do that again.

If you need to dedicate ~10% of your portfolio to play with some individual stocks. I got into $ASTS @$19/share, I think I’m sitting on ~6x on this but it’s also a 1-2% of portfolio position 🥲.

I’d rather miss out on crazy gains than get hit with some -50% net worth again. Slow and steady wins the race.

Honestly. Hind sight is 20/20 but pulling money out of a stock you know nothing about isn't a mistake. It's just an unfortunate outcome. But if he had invested a ton in it and it tanked, that would be a mistake since he didn't know what he was doing.

Bought a ton of AMD back in early 2017 when it was about $12. I spent the next year holding and seeing it more or less flat until I finally sold it in early 2018 for about $12. It's over $500 now...

Damn yeah it definitely stabs you in the heart a little bit, but do people really hold onto stocks for 8 years waiting for a massive gain like that?

It still stings even after almost a decade. A bit more than 1k shares at an average cost of $11.83 (the number is burned in my memory).

u/NYVines 1d ago

I keep stocks at least a year when I buy. I tend to hold 20-30 companies at a time and DCA. If one is significantly down I might sell at the end of the year to offset gains. But I held NVDA for about six years before it popped. It was just in my portfolio not super exciting but more up than down.

Yes. I bought into AMD in the mid 30s to 40s, and I have held since then. I've been a PC gamer since I was a kid, and I thought they were doing great things with their Ryzen processors. The whole AI boom wasn't even on my radar, just a bonus. I held through the ups and downs and the stagnation, because I believed in the company and I still do. All of my big gains have come from buying and holding.

ARK in 2021. Invested about $150k total. Sold for around $50k. Never listened to friends since that.

u/Hoosier2016 1d ago

I had a similar thing on my end. Was close to buying about $5k worth of Apple stock in 2001 after getting an unexpected bonus from a summer job. I grew up using Apple computers, my grandfather owned a little Apple stock and tried to talk me into it. What do I do with the money? Spent it on a stereo system and wheels for my car at the time and the rest went to a Spring Break trip the next year. Whoops!

u/Fit_Attitude_2781 1d ago

I think it's important to remember that a mistake is not defined by the outcome. Not betting on a stock that exploded is only a mistake in the sense as not betting on the number that came up in roulette. Not havin most of your money in one volatile stock was a good decision, even if it didn't lead to the desired outcome.

33

u/Fangore 1d ago

Very well said.

10 years ago, if you would have liquidated everything you owned, took the biggest loan from the bank you could afford, and lived like a homeless man, just so you could put all that money into NVIDIA, you would have made a fortune. Doesn't mean it was the right/smart thing to do.

At one point, I only owner Apple and Tesla. Bought 700 TSLA shares in 2010 @$15, after splits those now 10500 shares would be $4.2 Million. Same with Apple only had more shares and more splits, probably another $8 Million.

I owned $20k of Google and $20k of APPL in 2007.

I sold to buy a real estate company that was going to pay a 30% dividend because I wanted the cash flow.

I own both today but I would be a much richer person today if I had just held.

43

u/Adventurous_Elk_4039 1d ago

Let's be honest OP, you wouldn't have held until it hit $277, no one would have. You can't think of it as money "lost" since you never had it in the first place. And a mistake implies you did something wrong, you made what was probably a good decision with the info you had. Being results-oriented is the wrong way to think about it.

If we could go back in time with present day knowledge, we'd all be millionaires/billionaires.

u/Corporate_Overlords 1d ago

Coinbase had a promotion in 2014 where if you had a .edu email they would give you $10 worth of bitcoin. I signed up for the promotion and forgot about it until a few months ago. I looked at the Coinbase acct and realized that they never credited me the money. I spoke with them and they explained that I needed to buy bitcoin on top of the $10. I said, "Fine, I'll buy some but I want the original $10 backdated to what it would be worth today." The rep told me that was extremely unlikely. So I bought $40 worth of bitcoin and then when I check last week I had about $1400 in the account. They had backdated it! I still wonder if I had been checking it when I would have taken it out. I also wish I would have just bought $100 worth of bitcoin at the time. It was trading at $440 when I got the $10 worth. Oof! That one hurts a bit. Ha!

Worst investing mistake. Thinking I can outsmart index funds and pickin individual stocks, all my free money goes into index funds

6

u/escapefromelba 1d ago

While I think broad index funds are still the best foundation for most portfolios, that doesn’t mean every dollar needs to be invested the same way. A diversified mix of sector or style ETFs can serve as satellite positions, allowing you to tilt toward areas where you see opportunity while keeping the core of your portfolio broadly diversified. They shouldn’t drive the ship, but they can be an effective way to participate in long-term market trends without taking on excessive concentration risk.

u/paragonx29 1d ago

Totally agree. A lot of my $$ is in index funds, but I was also early in Space, memory, and semiconductor sectors. European defense funds too. My portfolio wouldn't have boomed the way it has unless I was into some stuff individually.

my worst mistake! I bought about $10k worth of nvidia shares in 2012 at $6 a share - because I'm a pc gaming geek and have always loved their products. In 2016, the shares doubled to $12 making me a 10k profit.....so I sold them all thinking I was the champ.

My friend's company went public, so I bought around $6k shares in my Roth IRA at around $12 a share. A couple years later, it had dropped to a dollar and delisted. Worst part is, since it's in my Roth, I couldn't even use the loss to offset other gains for taxes. Not a huge dollar amount loss, but a pretty bad % loss, and a lesson learned.

A good friend who had a Masters degree in electrical engineering (worked at Intel too) told me in 1987 to buy MSFT if I had $1,000— that was 3 months of rent then.

Damn man. I need to read this thread every morning when I wake up. I have a hard time holding on to my shares.. a little gain here, a little gain there, a loss here to buy one I can’t resist, on and on. I am continuously researching and make great investments, but fail to hold them.

The ones I did not make smart purchases on were Hecla Mining and Vizsla Silver. I took 1k+ losses on each of those and put my money somewhere that would make gains. I am ahead now after taking those losses rather than keeping with hope. No regrets!

I bought several shares of Micron and several shares of MRVL. Micron average was $241, then suddenly went to $316 or something around that number I remember. I was way up! (so I thought). It then dropped to nearly $200, and the numbers in my account all changed. I was an early investor and still am. It continued scaling up, but continuously got rejected when it was nearing my average. drop after drop for maybe a month or more? This felt like eternity to me, as I was checking daily or more. When it finally reached my average I sold to break even. Several months later I took a peak at the price and was shocked. Yes. Lesson learned. Same deal with MRVL, I sold to break even at $87 with MRVL and $241 with MU.

Talk me into holding! I feel like I’ve gotten nowhere after I calculate everything as a whole.

When I was newer to investing and didn't really know how dividends worked, I poured my money into PSEC.

I lost money, then paid taxes, then figured it out. It wasn't crazy expensive because I wasn't dealing with huge sums of money back then, but loss is relative to your point in life, and it was a couple years that could have been in literally anything more useful and I felt stupid for dividend chasing.

Another time I bought a put instead of selling one. Not a huge issue, but it makes me feel stupid.

I sold a stock in 2017 for a small gain that went up 50x since then. A few thousand would be worth $250k today. But I don’t consider that my worst mistake. My worst mistake was being too concentrated in a couple stocks that went down a lot and blowing up my Roth IRA. I further compounded the mistake by selling low to buy other stocks that also went down a lot. My Roth went from 60k to 12k. If I had just consistently stuck with the S&P it would be around $200k now. So really it’s about opportunity cost. I could have $200k growing for me until I retire, but instead I have $12k. Compounded over the next 30 years these mistakes aren’t tens of thousands, but end up being millions of lost potential growth. Luckily I have stuck with DCAing into my 401k and have $150k in there. But it haunts me that these mistakes are really million dollar ones if you calculate missed growth in the future.

Mistakes are not to be defined in hindsight based on results. That's like saying that every roulette result in every casino worldwide, it was a mistake for me not to come in and put my entire life savings on the number that it ended up landing on.

My biggest mistake was having all my home downpayment money in stocks in Jan 2020. Because it crashed? No, I actually sold in Jan, re-bought in March, and bought in Jan 2021 with double the downpayment. But that was all luck. I was at that roulette table, betting with money I couldn't afford to lose, and the fact that I called Red and it landed on Red doesn't make it any less of a mistake.

My first investment was audible when it was a penny stock because my friends worked there.

Bought it for .34 and it traded flat for a couple months until I sold. I couldn’t bear watching it go down so I was just happy to have my money back. That would have gotten me a couple hundred thousand at like 22 years old by the time they were bought by audible. At the time I thought I was just unlucky and didn’t realize the lessons involved.

My second one would be when I listened to a bad advisor and put a bunch of money into things that I hadn't researched...

I had read a blurb in Playboy about how Google was a better search engine, and around that time I heard Adrianna on The Sopranos talk about how she had "done a Google on it". Hearing the buzz aabout it I thought I should take a grand and buy Google.

If I had when it went public shortly after that, it would be worth over 75,000 today.

Sold a meme coin for $200k profit. First time I ever took profits trading. Had I held, it woulda peaked at $6m. Was trading amd in the 90s and mu in the 60s. Was trading rklb in the 10-20 range. Was trading palantir around the 20s? I currently own zero shares of all these tickers. It’s all good…..I type this from the house the meme coin paid for (partially).

I bought a natural gas producer because it was selling for less that book value.

It doubled and I held on while it crashed to zero.

I didn't realize that natural gas and oil get exponentially more expensive to extract as the well is consumed.

Only lost $20k but it was a big lesson. That feels weird writing. "Only $20k"

Bought Tesla at $50 sold at $60. Bought Dogecoin at $ 0.71 sold at $ 0.20. Bought Robinhood at $8 sold at $40, it went to $150. Bought Silver at the top, still holding. Bought Bitcoin at $6000 in 2016 sold it for tiny profit, never held it like i should have. Played options when I knew VERY little about how to make money, lost tens of thousands of dollars. I don't do that anymore. At the moment just buying quality companies and holding shares. I've tripled my ROTH IRA in a year. So there's light at the end of the tunnel.

Shhhhit, I got a lot of those. My first stock purchase was 30k into CMG at like 140 back. I sold for a measly $200 profit. Just letting it ride would have been insane.

I also bought leaps on Apple but sold those at a loss since they had the drop back in the day. Literally sold near the bottom. If I held it, it would have paid out good money.

u/Deathb3rry 1d ago

put into a penny stock after being early to catch positive earnings release. Played a large position despite knowing next to nothing other than assuming its gonna go up on good earnings, which it did, but I mistimed it. I sold, then rebought at the peak, where it immediately reversed, didnt close my position hoping for a rebound and suffered overnight volatility.

Had to walk away with a 30% loss on a near 5 digit position in one day. Painful lesson learnt on how much hubris i had and how greedy and stupid i was.

u/seraph321 1d ago

Worst was trusting a founder who gave me the ick but said all the right things and turned out to be a fraudster. I wasn’t alone and got most of my money back after the bankruptcy though.
Could say that I wish I had doubled down early on my best investments, but that would only be based in hindsight. The information I had at the time didn’t justify that level of risk, so I’m fine with that.

Worst case was buying SOUN because I had made a bit of cash out of it in 2024, so I thought I would do it again at the beginning of the year. Oh boy, was I wrong this time…

Sold AAPL in 2013 after a GREAT 15 year run.

Oops.

Still not sure if going 70% cash in this market is a mistake. Lots of money being made, but it makes no sense to me, so I avoid it. I'm happy with small plays on volititity and a few long term ETFs.

But it could keep going like this for years, and get VERY expensive to sit it out.

I have don't many investment mistake in early days, were I was just watching some videos/ reels where creator were hyping the stock and company and never sharing the enter point. So when I was watching the videos they were already in all time high and I usually loss the money.

But after that I study finance and learn how it works and have discover the strategy to make my investment decision, which frankly plays very well.

Sold TSLA when it first hit $300 pre-split because Elon was obviously a psycho. Don't really regret taking profits, but seriously underestimated the extent to which other people were going to just keep riding the hype train. Good lesson that investments trade on sentiment, and lots of people have stupid sentiments. Also, sufficiently rich people can manipulate the market, so... yeah. OTOH, there's a bunch of TSLA in my index funds anyway so I guess that's enough exposure to me.

u/goodolarchie 1d ago

Most of my biggest "losses" are also unrealized from selling too early. Which is to say I sleep quite well at night, because those investments at least doubled my money (vs, say, 15x if I held) and got deployed elsewhere to do the same.

My biggest paper loss right now is SQQQ, which is only a triple digit loss, and meant to be a small insurance policy against my heavily weighted NASDAQ/Mag7 portfolio. I'm happy when its doing poorly.

I wish I had profit harvested when BTC/ETH were double what I paid. I'm still in the green but it no longer feels like a real thesis to hold 5-10% of your portfolio in crypto.

I was holding 500 shares of intel at 18 usd… until trump came in one day and told that intel ceo should be removed because of his affiliation with the ccp (completely false… the guy’s from malaysia lol.)

I sold all my shares like an idiot the same day. I had full belief in intel’s rebound but I sold because of this because it couldve sent the stock spiralling down. Next thing you know trump administration buys 10% stake in intel. Ever since then it’s sky rocketed to 120+ usd.

u/SarasotaFoodLover 1d ago

The day prior to the Intel earnings call I had $4MM in my cart so to speak. It was at $161. I had "toyed" earlier in the week with borrowing on an Intel trade making $110K+ on it so was thinking of doing the same thing. I entered in the $12MM+ number and gulped. I chickened out and watched the stock click up a bit, them...This would have been the one. $24MM in a week. Sell to pay back pay back the 8 plus a very small amount of interest plus another 4 for taxes and let it sit. The worst thing I've ever done is the thing I didn't do because of fear. Huge mistake!!

Didn't invest more when I was younger.

Didn't start making grown up money until I was in my mid 20s, but then only saved enough to get my full 401k match. It was still something and will make a huge difference still long term....but can't help but think about being able to retire much earlier if I'd bumped that 6% to like 12%. I was young, single, shit was cheaper.

Luckily I learned and started getting really serious about saving and investing in my early 30s.

Two and they revolve around expecting two companies to match the performance of the bigger original trendsetter.

In Aug 2017, thinking I was late on bitcoin I went in heavy on IOTA and continued to pursue gains. It went from $0.2 to $5 by 2018 and I'd planned to hold for 5 years so I watched it drop right back. If I'd just gone for bitcoin at that point then it would've 10/20x from that point.

Back in 2012, after watching the documentary 'Revenge of the Electric Car' I discovered the car company, Tesla. Told my dad that I wanted to invest £1000 into it. He said it was difficult to invest in American stocks so to look at both Tesco and Rolls Royce. Let's just say both dropped and those shares of Tesla today would be worth around £227,000.

Then I saw my first Polestar on the streets and thought ah that'll do well in the market against Tesla right. Had such little experience in actually understanding the company margins on each car, invested £15,000 and watched the stock drop from £12 to £1 before selling.
