Short-term investing is traditionally defined as any investment held for less than 1-year. It doesn't matter if you trade buy a stock only to sell it 7 hours later in a day-trade or hold it for 6 months - both of these are considered short-term investments.
A long-term investment is any investment held for more than one year. -
Long Term Investment ChartThe time-frame for investing can have a big impact on investments for a variety of factors. It is widely accepted that long-term investment in a broad diversity of places is the most conservative and safest way to earn a return on your capital. Short-term investing in contrast, can be very volatile due to the many factors that determine a share price or interest rate.
As an illustration take a look at chart below. Over the long term, the investment gained a large amount, but short-term spikes (volatility) made the investment gain and lose value several times. - Besides gain or loss, the most important factor to consider when investing is taxes. The time frame has a significant impact on what is called capital-gain taxes. The tax code in the U.S. and many other countries is written to encourage long-term investing. The current capital gain tax in the U.S is up to 35% for most short-term investments. Long-term capital gains taxes range from 0 to 15%.
- Warren Buffett, a noted American investor once said, "In the short term the market is a popularity contest; in the long term it is a weighing machine." This can be interpreted to say that even if you make a good investment on solid fundamentals, it can still go down in the short term because of group psychology and techinical factors. Long-term however, investors find the quality companies and are rewarded.
- Overall, short-term investing should be seen more as gambling (high-risk and unpredicatible). You really have to be an expert in market trends to do well with most short-term investments. Long-term investing is less risky, and though you might have to go through many periods of losses and gains, your overall investment will likely go up.
