Right! I mean it’s a total joke! The people here that bought 2 days ago made 50% on their money and really we should have all bought BRK like you and doubled our money! Wait that took you years... never mind!
according to SEC most people that trade big boards under perform exchange indexes. Also over 90% of day traders go broke within a year. Does that mean people shouldn't trade? Just give your money to money manager that'll just buy some index funds for you? Or perhaps save management fees and buy index funds yourself? Then keep putting in more and more money over 20 years hoping to make something worth while?
Stick to your blue chips. Some prefer to trade and make money in shorter time frame. Making same % over few days that you will over next 20 years is a little better for some.
