#portfolio management

I just had the worst experience with my investment portfolio. I feel like I made a rookie mistake and now I'm paying for it. Maybe I'm just being too hard on myself, but I keep thinking about what I could've done differently. Anyone else ever have those 'what if' moments with their investments? 💸

so i was trying to diversify my portfolio rn and i think i made a kinda silly mistake tbh, i put a big chunk of my money into this one stock without doing enough research lol, im not even gonna say what it is but lets just say its not doing great, imo i shouldve juste stuck with index funds, anyone else ever do something like this? i feel like ive learned my lesson tho

tbh i was thinking about switching up my portfolio a bit, been reading about value investing and how its supposed to be way more stable than growth investing and i was wondering if anyoneelse has made the switch, like is it really worth it or am i just gonna end up with a bunch of undervalued stocks, lol my broker is always on my case about diversifying so maybe this is the way to go idk, i feel like growth investing is all about speculation and thats not really my thing, i like my investments to be a little more... substantial, like theres actually somethingBacking itUp, anyone have any exp withthis
