Wake
I have witnessed massive fortunes being made and lost in the financial markets. The primary lesson I learned was- Investing is not speculating and vice versa. If you want to get rich quick- go to Vegas or trade stocks and commodities. You'll probably end up broke, but you will have a shot. If you're a gambler take 2-5% of your portfolio and try your hand at market timing, options, or inverse funds/etf's. It can work out. Usually it doesn't.
If you want to become wealthy in a systematic and progressive way, invest in the stock market- but buy the whole shebang. Buy a diversified index fund (or ETF) that captures the entire market (vanguard total stock market or similar) Then regularly add to it. Hold your approximate age in a diversified bond fund like Vanguards total bond market fund. Rebalance once a year or after large swings. So if you are 40 years old - hold 60% stocks and 40% bonds. (this is an oversimplification for illustration purposes). You can adjust these percentages as you see fit, but the younger you are the more equities you should own. I have always been conservative and held a 60/40 portfolio for most of my life. I made a lot of money from boring old bonds......lol.
I do think we are going to see a correction or even a stock market crash- probably sooner than later. But I don't care!! I've already increased my allocation to fixed income and lowered my exposure to equities. That is what you do after making 30% the year before - you sell HIGH by rebalancing. I am holding a lot of cash too (cash is an asset class that does quite well in deflationary times) . If the market does fall precipitously, I will simply rebalance my portfolio and increase my exposure to equities.
Bottom line - nobody knows what is going to happen. At age 26 you have time on your side.
