Was never smart enough to get into chartology, never dumb enough to trade on it. I like Cramer. He talks about this stuff as a potential to game entry points, but copying 90% of great investors he's a value guy to the end. I watch charts when I'm interested in buying something, but mostly I buy after several years and a high level of comfort. Charts don't matter much when everything else is in line.
Do yourself a favor and stick to index funds for a long time. Dollar cost averaging is still alive and well. Follow a few simple to understand stocks for several years before possilby buying. Try to kill every investment thesis behind a stock you have. Don't ever care about being right or wrong. It's never about that. Don't step in front of the bond steamroller. It might not be in motion ATM, but no need trying to pick up that dime either.
Also, and most importantly (rule #1), if you think the world is going to end then don't bother investing at all. It's not going to end, yet this is the number one reason the average 401k skittish donk loses money year in year out.
Again, unless you are a genius and/or have 8 hours to spare per day, don't waste your time and go with index funds. Most people can make 5000 times the return doing a mindless job on the side than wasting time trying to be a hero while puting capital at risk.
Good luck. Throw away this advice like we all do and go pay your tuition, as we say. Let us know when you realize you didn't know what you thought you knew.
