I am going to hold onto my dip money here. I didn't build up cash to get in on a 10% drop. Especially when these prices were ATHs just 2 months ago.
Everybody is too sure that the economy and markets are going to continue booming. During Obama everyone always seemed to think a crash was coming and it never came, now that we have a pro business president everyone expects a big boom in the economy and markets. This is when the nasty correction will likely happen, maybe not this winter but sometime within the next year. Could be wrong, have been before for sure.
Like The Crazy Chinaman said, weak hands need to be shaken out. Too many weak hands and index worshipers who have never experienced a real crash. If we don't get a healthy drop soon then whatever comes in the next few years will be real nasty.
If one isn't invested they should get in for sure but if one is already invested heavily I would not throw all the dip fund into this thing just yet.
My very amateur opinion is don't worry if we take off from here, we will get a chance to buy Dow ~25,000 again. Just don't be broke when Dow >20,000 comes.
