Broker apps push the idea that you should constantly invest. Weekly! No, better - daily!
Just add small amounts, savings to your trading account.
Brokers have an obvious incentive: you pay comission on bought and sold stocks.
But you also pay with your time: top-up account, browse stocks, buy, sell.
And you also pay attention.
Yes, it may be wise to follow the news about the stock market, but from a distance.
Preferably without access to internet, on an uninhabited island.
That's why you should invest once and stay away from the stock exchange.
I used to be a day trader and think that I've made decent amount of money this way, about $2000 give or take.
But day trading is a second job, where you risk burning the money instead of getting a paycheck.
Now my investment strategy is this:
Spend as little time as possible on the stock market and what surrounds it.
Pick a small list of companies I believe in. (This is my way, do your own research!)
Buy the dip only if it feels right (10, preferably 20% or more discount).
The more I think about it, the more it seems to me that perfect strategy would be to buy once, hold and never sell.
Allocate a fixed amount of money that, if lost, you'd just shrug and don't stress over it.
Decide on a list of stocks/ETFs to hold indefinitely.
Don't top up your account after that.
Resist it as long as you can.
This aligns well with Warren Buffett's idea that a holding period of a wonderful company is forever.
