I am also terrible at market timing, so I have stayed pretty much 100% invested for the whole ride down, and have just moved my weightings according to their cheapness. It's the exact same methodology I used a year ago and it worked out quite well.
The only caveat is I have to be very very comfortable with each of my holdings long-term future otherwise it doesn't work, because I will go extra heavy on the most beaten-down ones since they will have become the least risky(in my mind anyways), and I usually only hold 5-6 stocks at a time so I could be 30-40% into one stock if the correction is deep enough. If I don't have complete faith in my company I will second-guess my decisions and will not be able to take advantage of the severe dips without worrying. That usually is an indication to myself that I should not be holding that company in my portfolio.
Good luck tomorrow everyone,
-Adam
