To my own knowledge and i will also be glad if i can get some opinions to me before you ask what, ask why. Why are you investing?
Investing is like a project. All projects have a goal or finished item.
What is your goal? Be specific. Getting rich is not specific. One million saved or $1000.00 a month in dividends is specific.
Your goal should be your realistic. One million is realistic. One billion is not. One thousand in dividends is realistic, $10,000 per month, no.
Define your time horizon. Months, years? The time will help you to stay on target and provides measurable times.
Always take risk into account. What is your risk tolerance?
In my part I always prefer to invest in 3 stages, it is more wise to invest in different prices, because if we invest our money on the current price and then it drops in the next days we will surely lose and the opportunity of buying more in lowest price will disappear because all our money is already invested. But if we invest in 3 stages we can still buy more when prices drops in the next days, that is what we called taking an opportunity everytime depending on the market situations.
