Short

The most fundamental method is “physical” selling short or short-selling, which involves borrowing assets (often securities such as shares or bonds) and selling them. The investor will later purchase the same number of the same type of securities in order to return them to the lender.

Short positions can also be achieved through futures, forwards or options, where the investor can assume an obligation or a right to sell an asset at a future date at a price that is fixed at the time the contract is created.

Impatiens balsamina (凤仙花)

Human use

Different parts of the plant are used as traditional remedies for disease and skin afflictions. Juice from the leaves is used to treat warts and snakebite, and the flower is applied to burns. This species has been used as indigenous traditional medicine in Asia for rheumatism, fractures, and other ailments. In Korean folk medicine, this impatiens species is used as a medicine called bongseonhwa dae (봉선화대) for the treatment of constipation and gastritis. Chinese people used the plant to treat those bitten by snakes or who ingested poisonous fish. Juice from the stalk, pulverised dried stalks, and pastes from the flowers were also used to treat a variety of ailments. Vietnamese wash their hair with an extract of the plant to stimulate hair growth. One in vitro study found extracts of this impatiens species, especially of the seed pod, to be active against antibiotic-resistant strains of Helicobacter pylori. It is also an inhibitor of 5α-reductases, enzymes that converts testosterone to dihydrotestosterone (active form of testosterone), thus reducing action of testosterone in our body.

In Nepal, the balsam leaves are crushed to dye fingernails on the day of Shrawan Sakranti (Shrawan 1). The day is also observed as Luto Faalne Deen (Go Away-Itch Day). Similarly, in China and Korea, the flowers are crushed and mixed with alum to produce an orange dye that can be used to dye fingernails. Unlike common nail varnish, the dye is semi-permanent, requiring dyed nails to grow off over time in order to remove any traces of color.
