In a bull market it’s too hard to tell if you are a genius or taking a random walk on a rising tide. Most think they are the former.
If you can successfully flip the colors, long green is sell, red is a sale, then you can beat the market in the only way small investors can. It is very difficult to do, because of that FOMO.
Some of the better stocks like Apple, Google, Amazon will be splitting in summer, that is a nice regular bump. Prices on some of these will never be this low again. Good time to start dipping buys into index funds (VOO, VTI, VOOG, VOE) etc if you can.
Dollar cost averaging works best if you aren't selling off every downturn and every so often banking some profits. If the only time you are selling is in downturns then that is a problem, selling should be as regular as buying.
A bit surprised this is so controversial. Taking gains regularly, even if you leave some gains on the table is better than only selling in downturns which is what happens in massive pullbacks. The massive pullback reds are when you should have some on the sideline to invest.
The base is sell high buy low, easier said than always done but if you have a regular sell strategy then you can bank some of those higher points just like DCA gets you into some of the lower points.
This doesn't mean you shouldn't dollar cost average or buy the dip, it means you have some cash to invest when there are pullbacks to get in lower. This allows you to continue doing other price target strategies and dollar cost averaging etc. You want some money in cash to be able to get into buying opportunities, like right now there is massive sale due to selling.
Basically have a regular buy strategy and a regular sell strategy.
