Buying individual stocks is a fools game for non-UHNI (poor) people. Keep your more-or-less passive funds investments, like low-fee mutual funds and index funds.
If you want more retirement money, it’s far better to spend the time to in yourself (skill upgrading/job upgrading) than it is to worry about trying to bet on individual investments. If you’re putting away 10% of your income per year into your retirement savings, you can double your retirement savings by increasing your job salary by 10% and then just putting all of the extra away too. Getting a 10% increase in your salary is a lot easier than picking a stock or stocks that will going to go up twice as much as the overall market.
