Expecting the company stock to remain on top is not a well thought out mindset. One must prepare for the inevitable and sometimes this involves financial ruin. The ideal world presents cash flows and investments that grow exponentially, but there is no ideal world for the typical worker and investor. When the stock fades and the options are few do not lose hope. Sometimes it's also not a good idea to cash out, as there can be a rebound.
Deciding where to put money early on makes a difference. Investing in a stock whether company oriented or not takes time and research. The fact of the matter is that the stock has to be worth the investment money. If it's not, then the best thing to do is to leave it alone. But where the company stock goes down don't be down and out. A portfolio comprises many resources including land and other mutual funds. When they say diversify it means that one should look for other means to collect.
The corporate world makes many promises one of them is immense pay. While they stand up to this claim (based on the job) there are still a few catches. There could possibly be a shortfall and the firm could go under or get taken over by some other entity. These are the things to think about when deciding where to work and how much trust to put into company longevity. Computer oriented startups, for example, are great on paper. But these firms have no clear track record and can collapse due to a variety of factors.
A fading stock can bring tears to the eyes of a hardened investor because the cash was not invested properly. It's easy to lose money when no thought is used to pick and choose the right collection on stocks. The general rule is to use due diligence. This means that efforts have to be in place to either consult with a professional or trust one's personal analysis. It's a speculation so it could go either way.
