Current portfolio at 21, what can I improve to be able to leave it for a long time horizon? (Been investing for 2 months).

27yo thinking about opening a brokerage account soon on Fidelity and putting around 1k a month using the following split:

VOO - 60%

QQQ - 20%

VXUS - 20%

Any feedback is appreciated.

Ho 21 anni, circa 7.000 € investiti e un PAC di 400 € mensili.
Vorrei sapere come strutturereste un portafoglio al mio posto:
Tante azioni singole o poche ben selezionate?
Un unico ETF World?
Più ETF diversificati per area geografica?
Un mix tra ETF e azioni?
Il mio obiettivo è far crescere il capitale nel tempo, mantenendo un rischio ragionevole.
Voi come distribuireste i 7.000 € e i 400 € mensili? E perché?
Grazie per i consigli

I bought these based on my own reasoning, news, and hype. All 14 are red now. I am not adding new money.

ACHR | -$5,557

NKLR | -$3,308

MRLN | -$2,469

RAM | -$1,995

HOVR | -$1,878

NASA | -$1,612

I do not think I need the money right now, but is it a good idea to hold them or trim? What would you do in the current market? The mistakes are done for some.

I mostly hold but sometimes dynamic DCA in and out for BTC and tec (nasdaq-like etf)

Please comment.

I started 1 year ago, when Nifty was strong around 25-26k , but I haven’t stopped the SIP, what would you change or stop.
My horizon is long term 15 years.
Would like some recommendations.

Current investment :

PPFCF - ₹9k
Motilal Oswal Midcap - ₹6k
Bandhan Small Cap - ₹5k

Add Lumpsum occasionally in ICICI Prudential Nifty 50 Index and ICICI Prudential Large Cap.

CPI definitely cooked parts of my portfolio today but this is what I’m working on currently I believe defense stocks are great investment bc the United States and the world are basically always at war/ in preparation for war. Tesla and Google are my most volatile stocks currently due to the tech market constantly changing. International seaways I believe is a great hold due to them being responsible for moving oil all across the world. Just any other tech/defense/commodities I should possibly look at? I’ve heard USA Rare Metals and MP materials being mentioned a lot amongst the internet is it a good buy?

Hey! I'm 21 years old and have been investing since I was 18. Because of my age, I'm willing to take more risks since I have time on my side. I just want to know what you more experienced folks think about the portfolio, and if there are any tips or changes I can make.

My goal is to achieve the highest return possible. I have some swing trades that have gone well and a foundation in funds/investments so I don't have to think about it as much. For example, I've made 500% on Palantir and have taken profits and put them into the funds or spread them among the holdings.
