Yes
People need fitness to swim 500m
Ive been in many rips. Usually only 30m to 50m wide. Go sideways swim in. Maybe a 250m swim.
You can often see rips from shore. Study the water pattern before going in
Put a 2 year moving avg on stocks. Std dev Bands at 10%, 25%, 33%.
If a stock is -33% by definition its cheap. At 33% its expensive.
Then look at roe, net profit margin etc.
They take advice from brokers. Brokers say buy near the top and sell near the low.
When BHP was $54 brokers said buy. One predicted $100 in 2 years, another more. Now $37. It might hit 100 in 2 years but could hit 30 soon.
When bhp was $14 in 2016 i saw many brokers saying sell. Said it would hit $8. $14 was the low.
They are like sheep.
