I am assuming (1) that you bought the stock for $1000 (a long position, not a short position), (2) you are discussing selling the stock after two weeks (a short term profit), and (3) US tax laws apply.
If you were to sell the stock at this point, your taxable profit would be $2; you would not pay tax on the $1000 originally invested.*
The simplest pro in this situation is you would collect your gain. The simplest con is that your transaction costs (mainly the broker's commission) probably is more than the profit.
Whether this would all be beneficial for you is a question you ought to ask your financial advisor (professional or not).
* A short term profit is taxed at your ordinary income rates. In the US this presently varies from 10% to 39.6%, exclusive of phase-outs.
