Apple stock seems to not be able to keep its gains.
This has been the history of Apple stock for quite some time. Once you understand the cycles and when they occur you can make some easy money using Apple as a stock that you trade around a core position. There are many strategies for making money in the stock market but Apple is a classic example of this one being the best way with a good margin of safety to make more money than just the age old strategy of buy and hold for dollar cost averaging as it continues to go up over the long haul.
Trading around a core position is where you buy in increments when the stock is in a dip, like now or yesterday, and sell a fractional amount of your total shares when the stock is on its frequent all time high like it was on April 9th. You never go all in at once and you never sell out at once. Trade commissions today are so low that this type of buy and sell is affordable. The company does not switch its profitability as frequently as the stock changes which means the company is solid but the stock is volatile and is used by the hedge funds to raise cash to cover their blunders. You and I can do the same except we aren't hedge funds so we use Apple to build a nice nest egg for our future. Note that this does require work so if you don't have the time to work at it on a daily basis, its best to not trade Apple but stick to simple investing, dollar cost averaging building the position. Soon you will also benefit with an income that you can reinvest as Apple has declared a small dividend too. Microsoft, IBM, and Intel are others that are excellent companies for long term that pay a dividend. I presently am not into these at this time. Google is only good for trading, IMO, because it has been flat for well over a year now. The company went flat when it decided to bail on the Chinese market.
