Nah bro, there's no way we can be at a market top. The people running all of the companies can't be smarter than us.
I am not strictly a value investor or fundamentals guy but I will say this: valuation doesn't matter until all at once it does. Fundamentals don't matter until all at once they do.
There is a reason I am doing more shorter-term trading like the short squeeze @Weston Nakamura posted. Because a day is coming in the future where people will realize stock prices can move in more than one direction. Leveraging up long at this point is how you can easily take your account to 0. Fortunes are made and lost in these types of situations.
