Making money successfully from speculation usually requires extensive research, time spent monitoring the performance of investments and reviewing investment decisions, a strong, analytical approach to decision-making that is devoid of emotions such as fear and greed, and the courage to either proceed or back away quickly when it is appropriate to do so.
An investor is someone who invests money in financial assets with the aim of making a profit. Speculators are investors, but not all investors are speculators.
An investor who is not a speculator is someone who takes a medium to long-term view of investment returns, being prepared along the way to accept short-term changes in investment conditions.
Whereas speculators are driven almost exclusively by return, investors find a balance between risk and return they feel comfortable with.
A combination of speculating and investing can work well.
Invest the bulk of your funds, and speculate with a small amount you can afford to lose, in the hope that you might just strike the jackpot.
