*sic*

Latin, "thus"; used to indicate that an error in the original has been replicated in a quote.

When you're quoting someone else, and the original includes an error (spelling, fact, conception) it may be necessary to assure readers that (a) you noticed the error and (b) it is not yours, but that of the person you're quoting. Since it is a Latin expression, it needs to be italicized, and in the Urban Dictionary this means enclosing it in asterisks.
His columns are full of brilliant insights such as this one:

"World War II erupted at Munich *sic* in 1941 *sic* because President Roosevelt *sic* was too weak-kneed to stand up to Hilter *sic*."

The man should not be allowed to go about unattended, let alone publish newspaper columns.

trade surplus

the amount of goods and services that a country exports, minus the goods and services that it imports *in a calendar year*. In 1999 Japan exported much more than it imported, so it had a trade surplus. The same year, the United States imported more than it exported, and therefore had a large trade deficit.

While Japan had a trade surplus and the USA had a trade deficit, both had something called a trade balance, which was negative for the USA and positive for Japan.

A country can have an overall trade deficit (like the USA in all years since 1980) and still have trade surpluses with individual countries (e.g., the USA occasionally has trade surpluses with Brazil).
Usually, when a country runs a trade surplus it tends to export the excess foreign currency back to the deficit country as portfolio investment. In this way, the foreign currency retains its value.

Corner

(FINANCE) Used either as a noun: a situation in which a trader controls the supply of a traded item, such as shares of stock, supplies of a commodity, etc.

Or else, used as a verb: to obtain control over the supply of a thing, so that one can drive the price up to extremely high levels.

Cornering the market for anything (or getting a corner) is extremely difficult and requires not only immense amounts of money (usually borrowed for the purpose), but also timing and the ability to bluff opponents.

A corner is ultimately a long position in the sense that it is a direct attack on investors taking a short position.
The corner must be timed very precisely, because it cannot last for more than a very short time. Even when the the price of the thing (like, say, silver) goes up to very, very high levels, more supplies cannot come onto the market or the corner will be lost.

At the same time, there has to be a target of the corner--some group of people who have to buy the cornered item no matter how high the price goes (otherwise, the quantity demanded will just go to zero). For this reason, corners are nearly always part of an attempt to squeeze the shorts.
