You can ask yourself if you are using the right stock market investing strategy when corrections like the current one do worry you. Corrections Happen. You can't avoid them. You do not know if or when they happen. So how do you deal with it?

It would be great if you can predict exactly when corrections will happen. Maybe some people can do this. But remember that predicting the future is very difficult and those who attempt so would in any case always need to follow the markets on a daily basis very closely and to be able and willing to act quickly. Trying to pre-empt corrections, also means taking the risk of additional trading costs and maybe missed gains if the markets do now behave as you has seen in your crystal ball.
