<prompt> Human: Im a relatively young guy who recently came into about 60k. I also managed to invest around 30k when Apple was around 330 despite knowing dick about the market, so Ive been very happy with the results. I want to invest again, a sizable chunk of the 60k probably half into Apple. Ive been trying to read up on it but right now the stock seems a bit volatile - having dropped from 640 to 580 and on its way back up. Basically I guess Im looking for advice, since I dont really know much about the stock market. Any help would be greatly appreciated. From searching around a bit, some people think that Apple is overpriced and will come down sooner or later. However Ive also read predictions from financial institutions such as MS that claim a bull of close to 1000. I am aware that the quarterly earnings will be released next week. My question is, what will happen when it does? From what I understand Apple has consistently exceeded expectations in this regard. But what has happened in the past when the quarterly earnings have been released? Does the stock drop anyway as Ive heard from some or will it climb? I know nothing is certain, but what Id like to know is would one in my situation buy now, while its at 610ish, before it continues to climb, or should I wait, let it drop again as it recently did before buying? Thanks to anyone for any advice.  <response>: Good investing means being well diversified. You probably shouldnt have more than 5 10 max of your money in any single asset.Placing all or a majority of your capital into a single asset isnt investing, its gambling. Youll unlikely find many on rpersonalfinancerpersonalfinance who would recommend that. My advice would be to invest in a diversified portfolio of stocks and bonds. If you dont have the knowledge to pick specific assets to invest in, you should look into ETFs or mutual funds to manage your diversification.For your specific questions about Apple stock, rinvestingrinvesting may be a better place to ask.
