Throw away account here as I'll share some financial details.
tldr: You won't make money day trading. Invest for the long term taking into account tax considerations and your risk appetite. I have and it has served me well.
In general I've learned that reducing fees [0] and thinking carefully about how to allocate investments across asset classes [1] is a much more successful strategy than picking individual stocks. Also try to hold on to investments for more than a year so you're taxed 15% on the profits rather than 30+% [2].
First thing you'll want to do is consider your asset allocation. I haven't used this tool myself, as I used an advisor, [3] but I consider Vanguard trustworthy as they are owned by their customers and have a good reputation. The purpose of a tool like this is to get a feel for how much you should be investing in equity vs bonds, vs real estate vs other exotic investments (hedge funds /private equity). I took a similar test through a financial advisor years ago and found it useful.
Over the last 9 years, I've invested roughly in this order of priority:
1) 401k for company matching & tax benefits - total profit of ~70k over the years. Starting from 0 balance 9 years ago, but recently have been maxing out contributions at ~17k per year 2) Exchange Traded Funds - SPY, DXJ, HEDJ. Essentially diversified, low fee investments in the US Stock market, Japan stock market and Europe. Total profit of ~30k over the years. 3) Bought a house, which I ended up renting. On paper profit of ~100k, but transaction costs (costs to buy and sell) eat into a large part of it. Long term it's a good plan. 4) Invested in a few individual stocks, lost a few hundred dollars. 5) Invested in options on a few individual stocks, lost ~3k. Learn about time decay before doing this.
Hope this helps!
