This answer is not a simple one.
I know a guy who gave up a job making over 100,000 dollars a year as a medical equipment salesman. They also paid for a lot of his expenses like a company car, telephone line at home, internet, cell phone, etc.
He traded very successfully over the years and turned tens of thousands into hundreds of thousands and then into millions. However, we have been in roaring bull market the last 2-3 years. You could have invested in most anything the last few years and it went up with a few notable exceptions. 100,000 invested 2-3 years ago in a diverse portfolio would have yielded substantial gains today. We could even blindly pick 10 stock symbols out of a hat from 2-3 years ago and a buy/hold strategy would have probably yielded substantial gains.
However, where are we going from here? I dunno. Are you able to trade in a real down unpredictable or sideways market?
We dont know what the future will bring. I hold down a job and trade the market at the same time. There are times when I am up to 2am doing research and completing tasks. Its very difficult. I do make more cash in the market then at my regular job. However, I choose to keep my regular job for security.
From 1997-1999 there was a huge bull market. I remember there were some daytrading brokerages that opened up where you could go in and use their systems to trade. There were these ridiculous commericals on television with the tow truck driver who owned an island from the proceeds he got from trading. It was a big party.
Then it happened overnight, the market went dark and people were losing their shirts. 2 years later, everything was horrible. Jets crashing into buildings, the good times were over.
Now we are at a point where the good times are back again and some people have forgotten the lessons learned from 1999.
I have not forgotten and do have a comprehensive risk management in place for myself. For one, I keep 6 months of cash in sleepy savings bonds at all times. I contribute the maximum into diversified retirement accounts and 1000 every two weeks to DRIP plans with those dividend stocks you love like Kelloggs and Colgate. Come on, you guys love the DRIP plans.
There is one thing that is certain. A downturn is in the future. It may not be next month, next year. It may take a decade or longer. Whenever it comes, it will be when you least expect it. The most expensive seat on the NYSE was purchased for $625,000 (six million in todays dollars) shortly before the 1929 crash. They didnt expect it.
I would say that you know yourself better then anyone. Ask yourself if you can manage the risk. The consequences are quite high if your wrong or fail.
There are a lot of persons (vendors) on this website who I will not mention by name. They respond very well to some of the posts providing lots of knowledge. They promote their prop trading firms and whatever products they have. These guys will disappear when the market turns bad again. Just like the tow truck guy with the island and the daytrading brokerages.
